NX-480 Wireless Motion Sensor Document Number: 466-1479 Rev. D May 1998 60-639 Installation Instructions Product Summary A motion sensor (passive-infrared or PIR) detects movement within a specific area by sensing the infrared energy emitted from a body as it moves across the sensor's field of view, causing a temperature change in the sensor's zones. When this motion is detected, the sensor transmits an alarm signal to the control panel. Use motion sensors to protect locations where door/ window sensors are impractical or not needed. For example, use a motion sensor to protect large areas or open floor plans. Motion sensors also provide backup protection for door/window sensors. The NX-480 Wireless Motion Sensor includes the following features: s 35 feet by 40 feet coverage area for standard and animal- alley lenses s Masking kit provided to block portions of cover- age area s 3-minute transmitter lockout time after an alarm that helps extend battery life s Cover-activated tamper (optional wall-activated tamper is included) s Supervisory signal transmitted every 64 minutes to the control panel s Sensor low battery reports (trouble) to the control panel s Field-selectable sensitivity options NX-480 Wireless Motion Sensor Installation Guidelines Motion sensors are ideal whenever it is not practical to install Door/Window sensors on every opening. Large areas in an open floor plan, downstairs family rooms, and hallways are candidates for motion sensors. Motion sensors are not suitable for rooms where pets can enter. Use the following guidelines for installing motion sensors. s If possible, locate sensors within 100 feet of the panel. While a transmitter may have a range of 500 feet or more out in the open, the environment at the installation site can have a significant effect on transmitter range. Sometimes a change in sensor location can help overcome adverse wireless conditions. s Mount the motion sensor on an insulated, outside wall facing in. s Mount the motion sensor on a rigid surface which is free from vibrations. s Position the sensor so it faces a solid reference point, like a wall. s Do not aim the sensor at windows, fireplaces, air conditioners, area heaters, forced air heating vents, or place it in direct sunlight. Sudden changes in temperature may trigger a false alarm from these devices. s Do not mount the sensor near duct work or other large metallic surfaces which may affect the RF signals (see RF Testing). Actual acceptable transmitter range should be verified for each installation. s Mount the sensor permanently on a flat wall or in a corner. Do not set it on a shelf. s Windows should be closed in any area which has an armed motion sensor. s A pet will trigger a motion sensor. See Animal Alley lens guidelines to use a motion sensor when pets are present. s Position the sensor to protect an area where an intruder would be most likely to walk across the detection pattern (see Figure 1).
