Warning light system |
(57) The present invention provides alarm apparatus (14) comprising at least one light
source (16) (preferably an electric light bulb), a detection circuit (preferably a
microphone) (32), and a power source (38) therefor, the light source being adapted
to attract attention and to be activated when the detection circuit detects a predefined
signal, wherein the detection circuit is maintained in constant ready condition and
the predefined signal is emitted by a hazard warning device, such as a smoke detector
(12), the apparatus serving to reduce response time before activation of the warning
light by being on constant standby and being useable with existing hazard warning
devices.
