[. . . ] To prevent possible SERIOUS INJURY or DEATH from electrocution, outputs are suitable ONLY for controlling low voltage devices, 24V max, ac or dc. Carton Inventory Swivel Bushing Base Station Passive Infra-Red (PIR) Motion Sensor Rubber Pads Batteries: If the AC adapter is not connected, the AA batteries in the Base Station should last up to one week. If the Base Station batteries are low, the Base Station will beep every 30 minutes. The AA batteries in the PIR Motion Sensor will last up to 2 years depending on use (lithium batteries are recommended for colder environments). [. . . ] Adhere rubber pads to the bottom of the base. 4 AA batteries are optional in case of a power failure. Step 2 B Install 4 AA Alkaline batteries. (Lithium batteries recommended for colder environments. ) Test light will flash. Step 4 A Learn Button Switch Settings Antenna PIR Motion Sensor Switch #1 Learn Button Switch #2 A Ensure Base Station and PIR Motion Sensor are in close proximity to each other. Press and release Learn Button on Base Station. OFF 15 Feet Detection Range ON 30 Feet Detection Range (Default) Switch #2: OFF Low Sensitivity ON High Sensitivity (Default) OFF 1 2 ON B Learn Button B Within 60 seconds, press the Learn Button on the inside of the PIR Motion Sensor. Test light will illuminate and Base Station will buzz. NOTE: To avoid unwanted detection of small animals move Switch #2 to OFF. 2 PIR Motion Sensor Installation Step 5 Step 7 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. Mount PIR Motion Sensor horizontally on solid surface a few feet off the ground and within 1/2 mile of Base Station (rotate sensor to access screw holes). Unit should be able to swivel as needed. NOTE: Keep PIR Motion Sensor antenna away from metal objects. Do not mount PIR Motion Sensor in direct sunlight, near moving tree branches, or in the path of a sprinkler system. Vehicle Alert Installation: For cars, the best mounting position is about 4 feet high, between 10-20 feet back, and angled to see the back of car after passing the sensor. Step 6 10' - 20' 3' - 5' Test PIR Motion Sensor by waving hand in front of sensor. Test light should flash and the Base Station will buzz. 3 Troubleshooting The PIR Motion Sensor lights up, but the Base Station does not respond. The PIR Motion Sensor must be programmed to Base Station (See Step 4). Ensure Base Station is on and the volume is turned up. The Alert is not getting expected transmission range. Keep both antennas vertical and keep PIR Motion Sensor antenna away from trees and metal objects. Ensure Base Station is in clearest possible sight of the PIR Motion Sensor. The less objects between the devices, the longer the range. [. . . ] Check the PIR Motion Sensor(s), if the LED illuminates on all of the PIR Motion Sensors, change the batteries in the Base Station.
