Conventional Fire Alarm Systems
A conventional fire alarm system normally consists of a control panel linked to a number of circuits of smoke, heat detectors and manual call points, with a number of sounder zones. Control Panel
The control panel drives the detection lines and the sounder lines, provides LED indications of fire, fault or normal conditions and contains switches to allow the sounders to be activated or silenced and the detectors to reset after an alarm. The control panel is powered from 240V mains, but contains backup batteries in case of power failure.
