IR flame detector RIV-601P/F

IP66

Cast aluminium watertight case, IP 66 grade protection (dust and water spray). Explosion-proof available with the model RIV-601P/FA. Power voltage 24VDC ±15% (20 to 28V). Current consumption 13 mA in stand-by (0.25W), 50 mA in alarm state (max 1.5W including 20 mA for test). Anti-inversion diode on +24V and + Test (T+). Spectral response infrared 1 to 3 micron. Tuned to flame pulsing frequency (flickering). Field of view 90° cone. The detector can see outside the field of view or indirectly by reflection, or even through smoke, with a reduced sensitivity. Sensitivity 2-3% of the distance, which means that the smallest detectable flame size is 2-3% of the distance. For example, at 10 m the smallest flame size is 20 cm. Typical covering figure is 400 square meters at 20 m distance. Alarm delay time set to 5 sec. Adjustable from 1 to 10 sec. Reset is automatic. The detector turns on 5 seconds after the flame is started. As soon as the flame stops, the detector returns off. Front LED lamp lights in alarm. It blinks shortly during the teletest. Output on changeover SPDT relay contact rated 1A 30VDC. Other output on NPN transistor open collector rated 50mA 24VDC, which goes low in alarm. Built-in "Teletest" device for the remote monitoring of the detector ability. Needs a 24VDC ±15% 20mA. Built-in modulator. When the teletest circuit is powered,a small incandescent bulb placed near the sensor starts pulsing so as to simulate a flame. During the test the detector turns on for half a second every 4 seconds. The teletest can be remotely controlled from the control panel, or can be wired for a continuous and automatic operation.
