GS300Mc Product Description

The GS300Mc Gas Detector has an override feature. This allows sensor testing without removing the electrical supply to Gas valves when applying test gas. The GS300Mc can also be set to meet requirements, for example the following can be changed using DIP switches:

•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 (latching or auto-reset)

The GS300Mc has two plug in terminal blocks. One for mains supply and alarm circuit wiring and the second for sensor connections. This reduces the chance of incorrect site wiring. The front panel has two overload LEDs which indicate when a short circuit or an overload has occurred on the sensor wiring.
