Product Description

Its range of intelligent addressable sensors has been specifically designed to operate with Cooper intelligent addressable fire systems. All sensors are third party approved to the relevant section of EN54 (part 7 for smoke detectors & part 5 for heat detectors).

The optical sensor (CAP320) is suitable for most applications giving the fastest response to slow burning or shouldering fires which give rise to large visible smoke particles.


The photo-thermal sensor (CAPT340) will respond quickly to fast clean burning fires yet maintain the advantage of optical sensors when detecting smouldering fires. The thermal enhancement of this sensor allows a higher alarm threshold which provides a greater rejection of false alarms. The sensor will also raise an alarm at temperatures exceeding 60ºC.

The heat sensor (CAH330) can be set to one of 3 modes 77ºC / 92ºC and rate of rise. These sensors are designed to be used in environments where the ambient conditions might cause false alarms if smoke detection were to be used, for example where there is a high level of dust, fumes, steam or smoke under normal conditions.
