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 |
