Abstract (en)
[origin: EP2479733A1] The device has a monitoring circuit (5) provided with end elements (9) and supplied by a power supply (6). A connection line (10) includes a signal line (11) that activates a locking device and an alarm sound. The signal line connects contacts of signaling devices (3) i.e. relay, of a smoke switch (1) in a series circuit. A deactivator (12) i.e. scratch bridge, of the smoke switch interrupts a connection of the end elements to one of lines of the connection line. The end element and the deactivator are arranged on a printed circuit board of the switch.
