GS100M Product Description

Firstly, the GS100M Gas Detector can be set up to suit requirements using DIP switches:

•Gas type (explosive or toxic)
•Positive Safety Option (on or off)
•Main alarm relay action (latching or auto-reset)

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.
