Gas Control Modules provide indication and control of 1-4 zones of gas extinguishing on F3200 and MX4428 CIE. They are pre-wired modules (requiring appropriate input/output modules). The modules have a 12 way screw terminal block for easy termination of the field wiring for the Local Gas Control Stations, gas discharged pressure switch, warning signs and gas release output. The connection for the Alert/Evacuate warning signs is a 2-wire polarity switched output that supports up to 10 AVI Mk2 units. All outputs can be supervised (this requires appropriate programming and configuring in the panel).
The gas control modules provide LEDs for each gas zone to indicate:
– Gas Initiated (red)
– Manual Release (red)
– Gas Discharged (blue)
– Gas Inhibited (yellow)
– Gas Isolated (yellow)
– System Inoperative (yellow)
A Gas Discharge Isolate switch that physically isolates both poles of the gas release actuator output is also provided for each gas zone.
