IR FLAME DETECTOR MODEL RIV-601P/FA EXPLOSION-PROOF ENCLOSURE

The IR flame detector model RIV-601P/F is an electronic optical fire detecting device which responds immediately to the thermal infrared radiation emitted by fire and is tuned to the flickering frequency of the flame to ignore sun and lamp light.
It is enclosed in a cast aluminium watertight case with IP 66 grade protection, which allows to withstand dusty environment and rain. An IP 66 explosion-proof enclosure is provided for the RIV-601P/FA model.
Nominal 24VDC input power is required, with wide span allowed, and two different outputs are provided: one heavy changeover relay contact, and one NPN transistor open collector.
Both outputs go into alarm state after a pre-set time delay, but they come back to the stand-by state as soon as the fire stops.
The delay time is normally set to 5 seconds, but can be set in the range from 1 to 10 seconds.
WHY IR (infrared) FLAME DETECTOR
Eye is faster than nose. In the event of live fire the IR flame detector responds immediately. Its behaviour is similar to that of the eye. In fact it "sees" the radiation emitted by fire, and its sensitivity is inside a cone of 90° which is called the field of view. The minimum flame size that can be detected by the RIV-601P/F varies with the distance. It doubles at double distance and is half at half distance. The sensitivity value is 2-3% of the distance. For example, at 10 m the smallest detectable flame size is 20-30 cm.
