Overview

A fixed single point alarm unit that meets the requirements for economic and reliable monitoring of gas levels in a wide range of environments from commercial premises through to heavy industrial applications that may require hazardous area sensing.

The 101 may be utilised as a standalone unit or as an addressable sensor forming part of the Combi CANbus addressable network system and therefore offering the features of our most advanced system. Typical monitor locations are:

Public buildings
Boiler plant rooms
Swimming pools
Water treatment works
H&V control systems
Manufacturing and process plants
