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 which may require hazardous area sensing.
Typical monitor locations are – public buildings, boiler plant rooms, swimming pools, water treatment works, H&V control systems, manufacturing and process plants.
Additional Features
- Low power consumption
- 4-20mA analogue output
- Sealed to IP65 rating
- Extensive fault detection circuitry
- Delay to alarm options
