Overview
The GS100M is a wall or panel mounted microprocessor based gas detector control unit. It has a secure test facility
which allows sensors to be fully tested by applying test gas without disconnecting the electrical supply to Gas valves.
The GS100M can be configured to meet customer requirements. The following parameters can be changed using on
board DIP switches:
(See Configuring the GS100M)
•
Sensor (on or off)
• Type of gas to be sensed (explosive or toxic)
•
Positive Safety Option (on or off)
• Main alarm relay action (latching or auto-reset)
The GS100M has two plug in terminal blocks. One is for the incoming mains supply and alarm circuit wiring and the
second is for connecting the sensor wiring.
This reduces the chance of incorrect site wiring. The front panel has two overload lights which indicate when a short
circuit or an overload has occurred on the sensor wiring.
