Overview

The GS300M is a wall or panel mounted microprocessor based gas detector control unit. The GS300M can be con-

figured to meet customer requirements. The following parameters can be changed using on board DIP switches: (See

Configuring the GS300M)

•

Number of sensors from 1 to 3

•

Type of gas to be sensed (explosive or toxic)

•

Positive Safety Option (on or off)

•

Main alarm relay action (permanent or auto-reset)

The GS300M has one fault relay that breaks the connection in case of system failure. This can be used to constant-

ly monitor the operation of the controller remotely (eg through a BMS). The relay driving techonogy (de-energized

when triggered) will ensure a prompt indication even in case of mains power failure.

The GS300M 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.
