GS300Mc Product Description

Firstly, the GS300Mc uses a colour changing display. Therefore, panel status is immediately obvious to the user. The Gas Detector also has an override feature. As a result, sensor testing can be done with full control over outputs. This can be set up to suit requirements 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)
•Oxygen Detection (on or off)

Two LED’s show either battery or a sensor wiring faults. Finally, there are two plug in terminal blocks. One for mains supply and alarm circuit wiring. The second for sensor connections. This reduces the chance of incorrect site wiring.
