ProFyre Conventional Detector Types

ProFyre Conventional Optical Detector

ProFyre Analogue Addressable Optical Detector

The optical smoke detector uses a pulsing IR LED and photodiode to detect IR scatter caused by smoke entering the chamber. The detector is particularly suitable for detecting optically dense smoke, involving materials such as soft furnishings, PVC, plastic, foam and all similar materials which produce small visible particles (0.5 to 10μm).

Approval Label

ProFyre Conventional A2R Heat Detector (Rate of Rise)

The rate of rise heat detectors use a thermistor arrangement to sense a quick rise in temperature and also a fixed threshold temperature of 57°C.

ProFyre Analogue Addressable A2R Heat Detector

Approval Label

ProFyre Conventional A2S Detector (Fixed Heat)

ProFyre Analogue Addressable A2S Detector

The fixed heat detector has a single thermistor arrangement that initiates an alarm at a temperature of 90°C.

Approval Label

ProFyre Conventional Combined Smoke & Heat Detector

The combined smoke and heat detector uses a combination of features from the optical smoke detector and heat detector.
