These detectors react to the whole range of fire products from slow smouldering fires,
producing visible particles to open flaming fires producing large numbers of very hot
smaller sized aerosols. It combines optical and heat detector technology to detect
clear burning fire products which hitherto could only be easily detected by ion chamber
detectors.
For normal ambient conditions, the high performance optical detector behaves as a
normal optical detector. Only when a rapid rise in temperature is detected does the
sensitivity of the detector increase and the presence of smoke will confirm a fire
condition which will be transmitted as an alarm level. Used in paint stores, battery
rooms, pump rooms and Zone 1Ro-Ro deck.
The MR601TEx detector is designed to comply with EN 50 014 and EN 50 020 for intrinsically safe apparatus and is certified:
- ATEX Code: Ex II 1G
- Cenelec Code: EEx ia IIC T5
