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
