Product Description

The GS300Mc Gas Detector 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 GS300Mc can also be configured to meet customer requirements. The following parameters can be changed using on board DIP switches:

•Number of sensors from 1 to 3
•Type of gas to be sensed (explosive or toxic)
•Intrinsically safe option (on or off)
•Main alarm relay action (latching or auto-reset)

The GS300Mc 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.
