BACKGROUND OF THE INVENTION
Field of the Invention
[0001] This invention generally relates to a signal station for a fire alarm system responsive
to a fire signal from means for informing fire occurrence such as a fire detector,
for actuating an alarm means to give an alarm, and more particularly to a signal station
of this type which is capable of outputting messages stored in a storage means concerning
actions to be taken when a fire arises, etc. in the form.of voice through a voice
synthesizing means.
Description of the Prior Art
[0002] Fact-finding of fires in buildings, hotels, etc. reveals, that most of conflagrations
or tragedies due to a fire can have been prevented if contact is quickly made with
a fire station when a fire starts or if people are guided more appropriately to a
safe place. The largest reason to cause such serious troubles lies in that janitors
of the buildings or employees of hotels have not taken appropriate actions although
fire alarm systems have operated properly.
[0003] In general, a conventional fire alarm system is comprised of a signal station connected
to means for informing fire occurrence such as a fire detector, push button, etc.
for receiving a fire signal therefrom, an alarm means including a bell, lamp, etc.
and an operating means for operating the fire alarm system and related facilities,
if necessary. This conventional signal station raises an alarm by sounding the bell
and lighting the lamp upon receipt of the fire signal, but it does not give instructions
for actions to be taken at the time of fire, such as operating procedures of the operating
means. Such procedures are usually described in an instruction manual or indicated
on a panel. If the janitors or employees are inexperienced or unpracticed to the operation
of the signal station, or they are upset, they cannot act quickly and appropriately
or cannot take necessary steps, or they operate the signal station wrongly. From this
fact, it can be understood that education and training of the actions to be taken
at the time of fire and operation training of the facilities related to the fire alarm
system are very important. At present, however, there are no measures to easily and
effectively educate and practice the actions required at the time of fire. In especial,
there is little chance to experience the operations of the equipments and facilities
related to the fire alarm system because they are not used daily. Moreover, it is
bothersome and therefore slighted to read the instruction manual to memorize the actions
to be taken at the time of fire.
OBJECTS OF THE INVENTION
[0004] It is a first object of the present invention to provide a signal station for a fire
alarm system which is capable of outputting, upon receipt of a fire signal, messages
for necessary actions which has been preliminarily stored in a storage means, in the
form of voice, to instruct janitors or employees to act quickly and appropriately.
[0005] It is a second object of the present invention to provide a signal station for a
fire alarm system which is capable of outputting, upon request, messages for instruction
manual of the fire alarm system and the related equipments and facilities, if necessary,
and messages for necessary action at the time of fire, in the form of voice, to educate
and train janitors or employees.
[0006] It is a third object of the present invention to provide a signal station for a fire
alarm system equipped with an announcing facility which is capable of announcing messages
for guide in an emergency.
SUMMARY OF THE INVENTION
[0007] In accordance with the present invention, there is provided a signal station for
a fire alarm system for giving an alarm upon receipt of a fire signal from a fire
informing means such as detectors or push buttons, which signal station comprises:
a storage means storing messages concerning measures to be taken at the time of fire
and/or messages concerning operating and handling method of the fire alarm system
and connected equipment or equipments;
a voice synthesizing means for synthesizing a voice signal for the message output
from said storage means;
a voice outputting means for outputting said voice signal as a voice;
a manual input means for generating a message output requesting signal for requesting
output of the message stored in the storage means; and
a processing means receiving and processing the fire signal and the message output
requesting signal to select a requested message from the messages stored in the storage
means and control said voice synthesizing means for vocalizing the message.

DESCRIPTION OF THE EMBODIMENTS
[0009] Fig. 1 is a block diagram of a first preferred embodiment of the present invention.
A signal station 10 for a fire alarm system is comprised of a processing means 11
for processing an input signal for controlling various equipments and instructing
necessary operations thereto, a storage means 16 storing messages for actions to be
taken against a fire, a manuar input means 15 for generating a signal for requesting
outputting of the messages of the processing means 11, a voice synthesizing means
20 for synthesizing voice signals for messages outputted from the storage means l6,
a voice outputting means 18 for outputting voice from the voice signal and a display
means 17 for indicating required matters. The signal station 10 further includes a
receiving means 12, an alarm means 13 and an operating means 14.
[0010] Fig. 2 illustrates one form of a fire alarm system to which the signal station 10
of the present invention is suitably applied. This fire alarm system comprises the
signal station 10, a signal line 1 connected to the signal station 10 and wired over
various places in a building, connection stations 2 each provided for respective fire
blocks and connected to the signal line 1, fire detectors 3a and push buttons manually
operable to inform a fire which are connected to each of the connection stations 2
together with identification signal connecting means 4 and alarm bells 5 and a fire
door releasing means 6 which are also connected to each of the connecting stations
2. This fire alarm system further comprises, as related facilities, a fireplug 7,
a sprinkler 8, etc. operatively connected thereto. An announcing facilities 9 may
also be connected to the signal station 10 according to necessity. It is not always
necessary to provide all these equipments and facilities, but other equipments or
facilities may further be connected, if necessary.
[0011] The processing means 11 is comprised, for example, as illustrated in Fig. 3, of a
central processor unit (CPU) lla, a read-only memory (ROM) llb whose contents are
not lost or erased, a random-access memory (RAM) llc free to write therein, an input/output
port (I/O PORT) lid and a bus (BUS) lie for connection therebetween. ROM llb stores
programs for CPU lla and CPU lla runs various processing operations according to the
programs. RAM llc is a memory temporarily used for running CPU lla. I/O PORT lld is
used for connecting various input/output equipments to the processing means 11, and
in the embodiment as illustrated, I/O PORT lld connects the receiving means 12, the
manual operating input means 15, the alarm means 13, the operating means 14; the display
means 17 and the voice synthesizing means 20 to the processing means 11 through respective
interfaces. Other equipments or facilities such as a printer may also be connected.
[0012] The receiving means 12 is comprised, as illustrated in Fig. 3, of a receiving circuit
12a connected to the signal line 1 and an interface 12b for inputting an output signal
from the receiving circuit 12a to the processing means 11. The receiving means 12
receives a fire signal from the fire detectors 3a etc. indicating fire occurrence
and further receives a block name signal and an identification signal from the connection
station 2 and the identification signal connecting means 4, respectively, and a trouble
signal and a normal signal, etc. The kinds of the signals other than the fire signal
depend upon the function of the fire alarm system employed, and it is not always necessary
for the receiving means 12 to receive all of these signals. In a fire alarm system
of the most simple construction, it will suffice for the receiving means 12 to only
receive the fire alarm signal. The receiving means 12 may further have a function
to transmit a signal to the connection station 2, the fire detectors 3a, etc. According
to circumstances, the receiving circuit 12a may be omitted. In this case, the interface
12b may be connected directly to the signal line 1.
[0013] The manual input means 15 is comprised, for example, as illustrated in Fig. 3, of
a switch array 15a and an interface 15b and generates a message output requesting
signal for requesting outputting of a message stored in a storage means l6 as will
be described in detail later. These messages can be selected and the selection is
carried out by.a code formed, for example, by on-off combination of the switch arrays.
By operating the manual input means 15, messages for necessary actions to be taken
at the time of fire or messages for instruction manual of the fire alarm system and
equipments connected thereto can be heard and training against a fire can be conducted
even at the,normal time. The manual input means 15 may alternatively be so formed
that the switches 15a are preliminarily combined to correspond respective codes so
that the codes may be selected by operating a selector switch or depressing push buttons
corresponding to the respective codes. Further alternatively, the manual input means
15 may be formed of a keyboard. In the latter case, input of sham fire data for training
can be carried out easily.
[0014] The alarm means 13 is comprised of a sound generating means such as a bell and a
lamp and adapted to be driven by a signal from the processing means 11 connected through
an interface (not shown).
[0015] The operating means 14 comprises a circuitry portion, switches for providing instructions
to the circuitry portion, a telephone, etc. and is adapted to be manually or automatically
operated to stop the sound of the alarm means l4, phone to required places and actuate
the relevant equipments such as the sprinkler etc. according to an instruction signal
from the processing means 11. This operating means l4 in the embodiment as illustrated
is further adapted to supply to the processing means 11 an operation confirming signal
for confirming that required operations are surely carried out in response to the
operations of the operating means l4. However, it is not always required for the operating
means 14 to have a function to supply the operation confirming signal. The operating
means l4 may be provided independently of the processing means 11 without being connected
thereto.
[0016] The display means 17 is comprised of a combination of a character board and an indicating
lamp, a simple display formed of 7-segment light emitting diodes, a liquid crystal
display for indicating a block name where a fire occus; actions to be taken, etc.
by letters or marks on a panel of the signal station. Alternatively, a CRT display
may be used as the display means 17. In this case, the messages stored in the storage
means l6 can be indicated simultaneously with or independently of voice synthesizing
by the voice synthesizing means 20. As the case may be, this display means 17 may
be omitted from the fire alarm system.
[0017] The storage means l6 is formed of one or more non-volatile read-only memories (ROM)
of random access type and stores messages for actions to be taken when a fire occurs,
instruction manual of the fire alarm system, fire training instructions and messages
for guide announcement according to necessity. The storage means l6 may further include
RAM, if necessary. Although the storage means l6 is connected to the voice synthesizing
means 20 in the embodiment as illustrated, the means l6 may alternatively be provided
in the processing means 11.
[0018] The storage mode of the messages in the storage means l6 is varied depending upon
the type of voice synthesizing and/or amount of messages. For example, in case of
voice synthesis by a voice synthesizing portion 22 as will be described in detail
later referring to Fig. 5, the messages are sequentially stored in the form of voice
parameters and an address table is provided for indicating a start address for every
message group or a word group.
[0019] Fig. 4 shows one example of the address table, wherein, for example, a common phrase
"A fire has started at" is stored in an area a
0 starting from a start address 100, block names such as "a utility room", "a warehouse",
"office" etc. are respectively stored in areas a
1 to a
8, starting from starting addresses 200 to 900, respectively. In areas b
0, b
1 and b
21 messages for measures to be taken when a fire occurs are stored, respectively. Similarly,
messages for fire training are stored in areas c
0 and c
1 and data for guide announcement is stored in areas d
0 to d . The start addresses shown in Fig. 4 are given for the convenience of explanation,
but, in fact, they are determined taking the lengths of the messages into consideration.
The address table may, alternatively, be provided not in the storage means 16 but
in ROM llb.
[0020] The voice synthesizing means 20 is comprised, for example, as illustrated in Fig.
5, of an interface 21 connected to a bus 19 from I/O PORT lld, the voice synthesizing
portion 22 for synthesizing a voice, an audio filter 23 for a voice signal and an
amplifier 24. The voice synthesizing means 20 is connected to the storage means 16,
the voice outputting means 18 and the processing means 11 so that it reads out messages
from the storage means 16 in response to an instruction from the processing means
11 and synthesizes voice signals for the messages for outputting them in the form
of voice from the voice outputting means 18.
[0021] The voice synthesizing portion 22 comprises, for example, as illustrated in Fig.
6, a voice synthesizer 22a formed in one chip LSI and a controller 22f for controlling
the voice synthesizing. The synthesizer 22a is comprised of a sound source 22b, an
interpolation circuit 22c, a digital filter 22d and a D/A converter 22e. In the voice
synthesizing portion 22, the controller 22f reads out voice parameters constituting
a message from the associated addresses according to an instruction from the processing
means 11, the parameters are sequentially input to the voice synthesizer 22a and a
voice signal is synthesized based on a pulse supplied from the sound source 22b. This
voice signal is supplied to the voice outputting means 18 through the audio filter
23 and the amplifier 24. The controller 22f outputs a busy signal during these operations.
This function of the controller 22f may, alternatively, be carried out by the processing
means 11. In this case, the controller 22f may be omitted. Further alternatively,
the controller 22f may be provided integrally with the voice synthesizer 22a and,
if desired, further integrally provided with the storage means l6.
[0022] The voice outputting means 18 comprises a speaker l8a provided at the signal station
10 and speakers l8b and l8c disposed at other places for outputting the voice signal
as voice. These speakers 18a, 18b and l8c are switcheably connected according to contents
of the messages. Of course, the speakers may be switched over by a manual operation.
As the case may be, the speakers l8b and l8c may be omitted. In addition to the speaker
or speakers, the announcing equipment may be connected to the voice synthesizing means
20 through similar switch.means.
[0023] Fig. 7 illustrates another form of voice synthesizing portion 22 which includes a
microprocessor 22i, ROM 22g, RAM 22h and a D/A converter 22e. In this voice synthesizing
portion 22 stores phonemic data of respective phones collected by PCM-recording a
natural voice and an editing and synthesizing program in ROM 22g. On the other hand,
messages are stored as character information in the storage means l6. The microprocessor
22i reads out a message from the storage means 16 and corresponding phonemic data
from ROM 22g according to an instruction from the processing means 11 and edits the
phonemic data according to the editing and synthesizing program to synthesize a voice
signal. RAM 22h is a memory temporarily used in the course of these operations by
the microprocessor 22i. In the case as illustrated in Fig. 7, the operation of the
microprocessor 22i may be imposed on the processing means 11 and the storage means
16-and ROM 22g may be provided integrally.
[0024] The method of voice synthesis is not limited to those as described above and another
voice synthesizing method may be employed in the present invention. For example, messages
may be PCM-recorded, reduced into suitable word or sentence groups to be stored in
a storage means, and read out by the processing means 11 or a special-purpose microprocessor
to edit and synthesize a speech.
[0025] The operation of the signal station for a fire alarm system according to the present
invention will now be described.
[0026] Fig. 8 is a flowchart of a main routine to be run by the processing means 11 of the
signal station of the embodiment as illustrated. To start fire signal monitoring after
the fire alarm system has been installed, the processing means 11 is subjected to
initialization 30 to clear memories and registers in preparation for running various
processing operations. The main routine is circulated at a constant speed.
[0027] The first operation is a signal line check 31 in which whether the signal line 1
(Fig. 2) is normally operating or not is checked through the receiving means 12. In
a succeeding signal line data inputting operation 32, a signal such.as a fire signal
and/or a trouble signal, when such a signal is supplied from the signal line 1, or
an operation confirming signal, when such a signal is supplied from the operating
means l4, is stored in a buffer means, e.g., a predetermined area of RAM llc, a buffer
register (not shown), etc. In a manual input data inputting operation 33, a message
output requesting signal is similarly stored in a predetermined buffer means when
such a signal is supplied from the manual input means 15.
[0028] A data processing operation 34 is provided for carrying out processing of various
input data,and is illustrated in detail in Fig. 9. First, a determination is carried
out at 40 as to whether the input data represents a fire signal. If the determination
is "yes," a flag representing a fire is set in a flag setting means such as a predetermined
area of RAM llc, a flag flip-flop (not shown), etc. and the block name and the identification
signal stored in the buffer means are decoded, converted into'the corresponding block
name and the identification number, and stored in RAM llc (as shown at 41 and 42 in
Fig. 9). The so stored block name and the identification number may further be converted
into start address data of voice parameters for the corresponding block name and identification
number stored in the storage means 16.
[0029] Then, a determination is carried out at 45 as to whether there is a trouble signal
representing a trouble such as disconnection of the signal line, a trouble with a
power source for the connecting means, disconnection of the fire detectors. If the
determination is "yes," a trouble-indicating flag is set in a flag setting means in
a similar manner to the case of determination at 40 and a block name in trouble is
decoded and stored in RAM lie (as shown at 46 in Fig. 9). On the other hand, the determination
is "no," a further steps are taken without carrying out the operations as described
above.
[0030] A further determination is carried out at 47 as to whether there is a normal signal
representing that the related facilities are not in operative states, a patrol confirming
signal for a patrol investigation, an operation confirming signal, etc.- If the answer
is "yes," flags corresponding to the respective normal signals are set in flag setting
means, respectively and the contents of the signals are decoded and stored in RAM
llc (as shown at 48 in Fig. 9).
[0031] If the answer to the determination at 40 as to whether the input data is a fire signal
is "no," a further determination is made at 43 as to whether there is an input signal
such as a message output requesting signal etc. from the manual input means 15. If
the determination is "yes," a manual input-flag is set in a flag setting means and
the content of. the input signal is decoded and stored in RAM llc. Although this step
is simply expressed by 44 as one operation in Fig. 9, the step is carried out according
to the content of the input, i.e., flags are set in corresponding flag setting means
for respective messages requested to be output, such as a message for instruction
manual, a message for operation training, guide announcement data, etc. After completion
of these operations, the program goes back to the first operation at an END position
of this data processing routine. On the other hand, if the determination at 43 is
"no," the program is branched to the decision point 45 to make determination as to
whether there is a trouble signal.
[0032] After the data processing operation 34, a control signal processing operation 35
is carried out according to the main routine. In this step, the respective flag setting
means are checked and an actuating signal for the alarm means 13 and a control signal
for the related facilities such as the fireplug 7, sprinkler 8, etc. is supplied.
[0033] In a display conducting operation 36, the content of the input signal, e.g., a fire
signal, a trouble signal, etc. is read out from RAM llc and indicated in the form
of characters and/or marks by the display means 17..In case a CRT display is connected,
an operation for indicating the same message as the message synthesized by the voice
synthesizing means 20 is also carried out.
[0034] In a voice control operation 37, a control operation for synthesizing of a voice
for a required message by the voice synthesizing means 20 is carried out. This operation
is illustrated in detail in Fig. 10. First, a determination is made at 50 as to whether
outputting of the required message is over. This determination is made by checking
whether the fire indicating flag and the manual input flag has been set by the. operations
shown at 4l and 44 in Fig. 9. More specifically, when these flags are in reset positions,
namely, when they have never been set or reset after completion of an operation 52
for actions to be taken at the time of fire (hereinafter referred to as "a fire action
operation") as will be described in detail later, the answer is "yes" and the program
is branched to pass the succeeding voice control operation and the processing means
11 runs a further operation of the main routine. On the other hand, when either one
of the flags is in a set position, the answer to the determination is "no" and the
succeeding voice control operation is carried out. This determination at 50 may be
omitted.
[0035] A determination at 51 is made as to whether messages to be output are fire data such
as data for actions to be taken when a fire occurs, etc. If the answer is "yes," the
fire action operation is conducted, and if the answer is "no," the program is branched
to a further determination. At a decision point 51, a determination is made as to
whether the messages to be output are messages for instruction manual and/or messages
for operation training. If the answer is "yes," an operation (as shown at 54) for
explaining instruction manual for the fire alarm system and the
' related facilities (in case such facilities are not connected, explanation for them
is not necessary as will be described in detail later) and an operation at the time
of training are carried out. If the answer is "no," the program is branched to a further
determination. At a decision point 56, a determination is made as to whether the messages
to be output are for guide announcement, and if the answer is "yes," a guide announcement
operation 57 is carried out, whereas if the answer is "no," the program is branched
to another step of the main routine.
[0036] Among the determinations 51, 53 and 56, the determination 51 as to a fire data is
made with priority, so that, when a fire signal is received during the processing
of other messages such as messages for in
7 struction manual etc., the fire action operation 52 is carried out through the determination
at 51. These determinations at 51, 53 and 56 are made by checking the states of the
flags set by the data processing step 34 as in the case of the determination at 50.
[0037] . In the fire action operation 52, as illustrated in Fig. ll, a determination at
60 as to whether a fire occurrence is already informed is first made. If the determination
is "no," a fire information is made. If the determination is "yes," the program proceeds
to a further determination at 62. This determination at 60 is made by checking a fire
informing flag set in a flag setting means after completion of a common phrase outputting
operation 77 as will be described in detail later. Further determinations at 70, 74
and 76 as to whether the block name on fire has been read out, as to whether the common
phrase has been uttered and as to whether the block name has been uttered, respectively,
are made in similar manners.
[0038] In a fire information 61, as shown in Fig. 12, the determination is made at 70 as
to whether a block name on fire has already been read out. If the answer is "no,"
the block name is read out from the fire data stored in RAM llc and a start addresses
of voice parameters corresponding to the block name stored in the storage means 16
are computed from the read out block name. This computation is carried out referring
to the address table provided in the storage means l6 or ROM llb.
[0039] Then, a determination is made at 73 as to whether the voice synthesizing means 20
is ready. This is done by checking whether a busy signal is supplied from the voice
synthesizing portion 22 through
.the interface 21 as illustrated in Fig. 5. If the answer is "no (busy)," the program
is branched to a further step of the main routine, passing the succeeding voice synthesizing
operation. The processing means 11 repeats running of the main routine until the determination
becomes "yes (ready)." If the answer is "yes" or the answer becomes "yes" after repition
of the main routine, the determination at 74 as to whether the common phrase has already
been uttered is made at 74.
[0040] If the answer is "no," the start address, for example, #100, of the common phrase
"A fire has started at" to be read out from the storage means 16 is applied to the
voice synthesizing portion 22 and a start signal is supplied thereto to synthesize
a voice signal for vocalizing the common phrase (as shown at 75).
[0041] If the common phrase has already been uttered, a determination is made at 76 as to
whether the block name has been uttered. If the answer is "no," a start address, for
example, #200 of "utility room" to be read out from the storage means l6 is applied
to the voice synthesizing portion 22 and a start signal is supplied to synthesize
a voice signal for uttering the block name (as shown at 75). If the block name has
already uttered, the processing means proceeds to a further step without carrying
out the above-specified operation.
[0042] Thereafter, a determination is made at 62 as to whether main and local sounds are
stopped as shown in Fig. ll. The main sound is a bell'of the alarm means 13 provided
in the signal station and local sounds are alarm bells provided in the respective
fire blocks. If the answer is "no," an instruction for stopping the main and local
sounds is vocalized by the voice synthesizing means 20 by the same procedure as that
of the fire information operation 6l. This instruction may, for example, be such a
message as "put a main sound stopping switch and a local sound stopping switch to
a stopping position."
[0043] If the determination at 62 is "yes," a further determination as to whether the spot
has been confirmed is made at 64. The latter determination is made by checking the
status of a predetermined flag of the flag setting means. When the operator has put
a spot confirming switch of the operating means l4 provided at the signal station
to an "on" position, the predetermined flag has been in "1" position. If the answer
is "no," a spot confirming instruction 65 is carried out in a similar manner. This
instruction may, for example, be a message "Dial no.···, or rush to the spot for making
confirmation. When confirmed, depress a confirmation switch."
[0044] If the determination at 64 is "yes," a further determination as to whether an action
after spot confirmation has already been taken is made at 66. This determination is
made by checking the position of a corresponding flag of the flag setting means which
is in "1" position by an operation confirming signal from the operating means 14 indicating
that the sound stopping switch is in the predetermined position. If the answer is
"no," an action instruction 67 after the spot con-
firmation is carried out in the same manner as described above. This instruction may,
for example, be a message "If actual fire, contact the fire station and guide people
to a safe place. If not, reset by operating the resetting switch and return the sound
stopping switch to the predetermined position." ,
[0045] The fire action operation as described above is carried out in a manner such that
whether the operator has carried out required operations or taken required action
is determined by the processing means 11 and necessary message or messages selected
from the messages concerning measures to be taken when a fire starts are output, in
the form of voice, according to the result of the determination. By this operation.,
the operator can conduct necessary operation and take the necessary action. However,
it is possible to employ a system in which the determination is not carried out and
all the messages are repeated sequentially. In this case, it suffices to apply only
a start address of the messages to be output to the voice synthesizing means 20, so
that the program of the processing means 11 can be simplified and the load thereof
can be reduced.
[0046] . The operation 54 for instruction manual is for explaining a method for handling
the fire alarm system and the related equipments and facilities. As to the related
equipments and facilities, explanation is made only for the equipments and facilities
which require manual operations, or the explanation may be omitted. The explanation
comprises informations and messages of the status of the fire alarm system and the
measures to be taken at the normal time, at the time of power stoppage and at the
time of fire. This explanation is output by an instruction manual output requesting
signal from the manual input means 15.
[0047] An operation 55 for training is carried out following the operation for instruction
manual in the embodiment as illustrated, but it may be carried out independently.
In this operation, as shown in Fig. 13, a determination is first made at 80 as to
whether the training starting message is over. If the answer is "no," a message 81
for starting training such as "Now, operation training starts. A fire alarm is given,
so please conduct operations according to the instructions" is uttered. Then, a fire
alarm 82 is given. On the other hand, if the determination at 80 is "yes," the program
is branched, passing the aforesaid operation. Then, the routine of the fire action
operation 52 is called allowing the messages for the measures to be taken at the time
of fire to be uttered. Thereafter, a determination as to whether the fire action has
been taken is made at 83. If the answer is "yes," such a message as "Now, training
is over." is uttered to end the operation (as shown at 84).
[0048] In the guide announcement operation 57, emergency equipments of the building, emergency
system, caution at the time of fire, etc. are given to the announcing facility in
the form of a voice signal. The announcement may be given whenever desired except
for at the time of fire or training. For example, in hotel etc., the messages may
be broadcast upon request by lodgers. Where a message for guiding people to a safe
place is stored in the storage means l6, the guide announcement can be made properly
at the time of fire as well as at the time of training.
[0049] At the completion of the voice control 37, the processing means 11 resets the flag
associated with the voice control which is set in the flag setting means, after giving
instructions to utter the last messages in the fire action operation 52, operation
55 for the training and the guide announcement operation 57, respectively.
[0050] After completion of the voice control, the main routine of the processing means 11
returns to the signal line check 31. However, if the related equipments and facilities
such as an automatic fire testing equipment, an indication testing equipment, a printer,
a communication means, announcing means, etc. are connected, the main routine returns
to the signal line check 31 after completion of the control operation for these equipments
and facilities. Where the printer is connected, not only the fire data but the times
when the required operations and actions are taken are printed out, so it becomes
easy . to know whether such operations and actions have been done properly. To print
out the times, a clock must be connected.
[0051] The speakers l8a, l8b and l8c of the voice outputting means l8 are switched so that
all the speakers 18a,-18b and
l8c or at least the speaker 18a may be connected in case of a message, for example,
by a fire signal and only the speaker or speakers selected by the manual input means
15 may be connected in the remaining cases, under control of the processing means
11.
[0052] Fig. l4 illustrates another embodiment of the signal station for fire alarm system
according to the present invention. In this embodiment, the receiving means 12, the
alarm means 13 and the operating means l4 are provided separately from the processing
means 11. The receiving means 12 is formed of hard-wired logics such as a relay etc.
as in an ordinary fire alarm system, and the alarm means 13 is driven by the hard-wired
logic. The processing means 11 is connected to the receiving means 12 through an interface
(not shown) or includes the interface for connection to the receiving means 12.
[0053] The signal station 10 of the present embodiment is suitably employed when it is required
to additionally import a function to output, in the form of voice, messages for the
actions to be taken at the time of fire etc. to a conventional signal station for
fire alarm system.
[0054] The processing means 11 operates and controls voice synthesizing, in substantially
the same manner as in the first embodiment, upon receipt of a fire signal. In this
embodiment, however, the messages are simply repeated because the operating means
l4 is not connected to the processing means 11. Of course, the operating means l4
may be connected to the processing means 11 as in the first embodiment according to
necessity, to select the appropriate messages by determining as to whether required
operations are carried out. Although the storage means l6 is,provided in the processing
means 11 in the embodiment as illustrated, it may, of course, be connected to the
voice synthesizing means 20.
[0055] In the foregoing embodiments, the signal station 10 receives a fire signal etc. through
one signal line, but a plurality of signal lines may be connected or different types
of fire informing means may be,connected to the respective signal lines. In these
cases, a program for searching fire data of block names corresponding to the respective
signal lines is provided to operate the searching operation by the processing means
11.
[0056] As described above, according to the present invention, the messages concerning the
measures to be taken at the time of fire can be automatically output in the form of
voice, so that it becomes possible to instruct the, janitor etc. to act quickly and
properly. At the normal time, messages for the instruction manual for the fire' alarm
system etc., messages for operation training, etc. can be output in the form of voice,
upon request, to conduct training of the janitor etc. In addition, if connected to
the announcing equipment, explanation of emergency equipments, messages for guiding
for leading to a safe place, etc. can be announced.
