Page 2: Technical Specification
Both detectors combine Microwave and Passive Infra Red (PIR) technologies in a single small detector. However, the 1081 detector is designed for wide angle applications, while the1082 detector is designed for long range (Corri- dor) applications. - Page 3 1081/1082 Technical Specification Detection Pattern 1081 Wide Angle 21.3m, 90° angle at 2.5-3.65m from floor. Figure 1. 1081 Wide Angle. 1082 Long Range 30.5m. 10° angle at 2.5-3.65m from floor. Figure 2. 1082 Long Range. Operating Temp. -10° C to +55° C MW Range Adjustable 100 - 30% by potentiometer.
- Page 4 Wiring the Detector 1081/1082 Infra Red Sensor Dual element pyroelectric detector, hermetically- sealed. Microwave Supervision In the event of a microwave section failure, super- vision circuitry reverts unit to PIR only operation and causes PIR to convert from Single Edge to Double Edge PIR operation.

Setting the Lens Carrier Position. Walk in front of the detector. Mark the maximum sensitivity point for each lens segment by observing the brilliance of red light through each lens segment.
- Page 7 1081/1082 Testing Once the detector is installed and the PIR lens pattern adjusted, both the PIR and MW sensors must be walk tested to ensure that the required area is fully protected. Note: If Remote LED Test Enable is used, ensure that the control panel or test switch is in the Walk Test position before proceeding.
- Page 8 Masking 1081/1082 NOTE: Do not, UNDER ANY CIRCUMSTANCES, fit links over both the Microwave and PIR test jumpers at the same time. Masking It may be impossible to avoid problem areas within the PIR surveillance pattern, e.g., hot surfaces or radiators. If false alarms are established during walk testing and the cause cannot be removed from the protected area, locate the cause and establish the lens segment covering the particular area.
