Model 836LM PERIMETER ALERT SENSOR Overview The Perimeter Alert Sensor is a Passive Infra-Red (PIR) Motion Sensor that detects movement of people and vehicles, while allowing small animals to pass through undetected. Each sensor has its own unique ID, for a secure radio link. The base station (not provided) can learn the signals of up to 8 sensors. The base station gives a single beep for the first sensor that is programmed, a double beep for the second, and so on. Additionally, multiple base stations can work with the same sensor to sound in different places.

Tighten screw until PIR Motion Sensor stays in place when repositioned. 2 Install 4 AA Alkaline batteries. (Lithium batteries recommended for colder environments.) LED light will flash. SWITCH SETTINGS Antenna PIR Motion Sensor Switch #1 Learn Button Switch #2 3 A Ensure Base Station and PIR Motion Sensor are in close proximity to each other. Press and release Learn Button on Base Station. Buzzer will sound. B Within 60 seconds, press the Learn Button on the inside of the PIR Motion Sensor. LED light will illuminate and Base Station will buzz. 4 Insert battery pack facing away from circuit board and fasten cover with the smallest screws (provided). NOTE: Ensure the batteries do not touch the circuit board and the antenna and battery wires are not pinched. Learn Button Learn Button SWITCH #1: OFF 15 Feet Detection Range ON 30 Feet Detection Range (Default) SWITCH #2: OFF 12 ON OFF Low Sensitivity ON High Sensitivity (Default) NOTE: To avoid unwanted detection of small animals move Switch #2 to OFF. 5 Test PIR Motion Sensor by waving hand in front of sensor. LED light should flash and the Base Station will buzz X number of times indicating which sensor has been activated. 1
