Description
The relay circuits in the GJD-L3C system have relay contacts for low alarm level, high alarm level and system fault.
The relay circuits facilitate the control of external functions like ventilation systems, magnet valves, sound beacons etc.
The system can be programmed so the alarm is activated in the event of increasing or decreasing concentrations, typically used when the oxygen level is monitored.
GJD-L3C is equipped with a fault-finding circuit, that also monitors the detector cable.
The central alarm unit is encased in a sturdy, granite-grey plastic cabinet with a transparent lid.
