The SR135 FIRE 24 V is a high-power back-up battery sounder (105 dB at 3 m) protected against tampering
(opening, tearing off). It features a 10 W flasher and a sound/flash timer, variable with adjustable trimmer from
1 min. to 7 min., which trips in case of prolonged alarm (e.g.. connection cable cutting). It has a first switch-on
stop function to prevent the sounder from tripping during installation (for enabling the sounder for normal use
it is necessary to activate/deactivate alarm start).
