22318.10.03 15.09.05 1 1. System description. Fireray 50/100ru detector comprises a transmitter and receiver contained within one enclosure. The detector installs to the building fabric between 1 and 2 feet from the ceiling. The transmitter emits an invisible infrared light beam that is reflected vi...
22318.10.03 15.09.05 2 3. Detector positioning. An infrared signal is projected out of the transmitter optics (see fig 3) to the reflector placed at the opposite end of the detection zone. The signal is reflected back to the receiver where it is analysed for fire and trouble. It is important that th...

Select the required alarm threshold using switches 3 and 4 (see fig. 4. For switch configuration settings). The factory default setting is...
22318.10.03 15.09.05 4 5. Prism targeting mode. Apply power to the detector. There is a 5 seconds pre-charge delay after power is applied to allow the internal circuits to stabilise correctly. After this period the red indicator will flash once to indicate that the model is a 50ru or will flash twic...

Cover the prism totally with a non-reflective material and confirm that the detector indicates a trouble condition after approximately 10 seconds (the amber led on the detector will illuminate, and the trouble relay opening will indicate this). The trouble c...
