Wireless Infrared Motion Sensor (490-2025A) Installation Faxback Doc. # 18323 Follow these steps to properly install the motion sensor. 1. Choose a mounting location. 2. Temporarily place the motion sensor at the mounting location. 3. Test the coverage area and range. 4. Permanently mount the motion sensor. CHOOSING A MOUNTING LOCATION There are some things you should consider when you choose a mounting location for the motion sensor. The sensor should be mounted on a wall. The sensor should be mounted 6½ feet high and parallel to the floor for a maximum coverage area of about 43 feet long by 54 feet wide when SENSITIVITY is set to MAX. (When SENSITIVITY is set to MIN, the coverage area for these mounting specifications is about 23 feet long by 31 feet wide. The maximum transmission range from the sensor to the base is about 150 feet (in open space with no obstacles). Walls, windows, furniture, and other similar objects between the sensor and the control base can decrease the range. Concrete and metal objects decrease the range the most. Mount the sensor where there are as few obstacles as possible between the sensor and the control base. Mount the sensor where an intruder would move within the sensor's coverage area. In addition, to avoid false alarms, mount the sensor: Out of direct sunlight. Away from heaters or any other device that quickly changes temperature within the coverage area. Away from air conditioners or other devices that blow air directly on the sensor or create strong drafts within the coverage area. So the coverage area is above where small pets and children will trigger the sensor. SENSOR COVERAGE The sensor divides its coverage into six upper sectors and three lower sectors. The upper sectors cover a horizontal area 78 degrees wide. The lower sectors cover a horizontal area 60 degrees wide. NOTES: There is a non-coverage area of 2 feet directly in front of the sensor (16 feet with the lower-sector filter installed). The lower sectors can be disabled. See "Using the Lower-Sector Filter,". Both upper and lower sectors cover a vertical area about 20 degrees wide. The sensor's coverage depends on the height and angle of the sensor, the SENSITIVITY setting, the shape of the protected area, and the texture of the walls and other surfaces in the area. The sensor is most sensitive to motion across the sectors and least sensitive to motion toward or away from the sectors. NOTE: The following measurements are based on the sensor being mounted 6½ feet off the floor and SENSITIVITY set to MAX.

You might want to check several locations to determine the best permanent mounting location. One simple way to check the coverage is to place the system on a stepladder at the desired height. Before permanently mounting the system, you must test the coverage and range of the sensor. TESTING THE COVERAGE You must test the sensor's coverage to be certain it covers the area you want it to monitor. Follow these steps to test the sensor's coverage. 1. Set the sensor's ARM/DISARM switch to DISARM. 2. Confirm that the protected area is clear of people, pets, and other potential causes of false alarms. 3. Walk around the protected area and look at the sensor's indicator. When the sensor detects motion, the indicator lights. 4. If the sensor does not detect your motion, do any or all of the following. Adjust the sensor angle. See "Adjusting the Sensor Angle,". Change the setting of the SENSITIVITY control or PULSE switch. See "Adjusting the Sensitivity" and "Setting the Pulse Switch,". Change the location of the sensor. After you make the adjustments, walk around the protected area again. 5. Walk outside of the protected area. The sensor's indicator should not light. If it does, find whatever is causing the false alarm and remove it from the area. Repeat Steps 3 and 4. TESTING THE RANGE The range is the distance from which the sensor can transmit a signal to the base. Before you permanently mount your motion sensor, you must test the range. Follow these steps to test the sensor's range. 1. Press TEST on the base. The TEST indicator lights. 2. Press TEST on the sensor. The sensor sends a test signal to the base and the sensor's indicator flashes. If the base receives the signal, it sounds a short tone. NOTE: You may need someone to stand next to the base to hear the tone. If the tone does not sound: The sensor's battery is low or improperly installed. Check the battery and replace it, if necessary. Then test the range again. The sensor might be out of the base's range, or something might be blocking the transmission. Move the sensor or base to another location, then retest the range. 3. Press TEST on the base to exit the test mode. The TEST indicator turns off and the base enters the disarm mode. ADJUSTING THE SENSOR'S SENSITIVITY Using a small, flathead screwdriver, rotate SENSITIVITY clockwise (toward MAX) to increase the sensor's sensitivity or counterclockwise (toward MIN) to decrease it. If you have frequent false alarms, rotate SENSITIVITY all the way to the left (MIN). ADJUSTING THE SENSOR'S ANGLE The sensor is attached to a ball and socket joint so you can adjust it to a variety of angles. To adjust the sensor's angle, loosen the collar screw at the neck of the sensor. Then carefully move the sensor's head for the desired angle, and tighten the collar screw. To determine the sensor angle, use the supplied angle gauge template (printed on the insert). Place the gauge against the sensor and wall, as shown and rotate the sensor to the desired angle. SETTING THE PULSE SWITCH When the sensor detects a temperature change in its coverage area, it registers the change as a pulse. The setting of PULSE (1, 2, or 3) determines how many pulses the sensor must detect before it signals the base. Set PULSE to 1 when you need the sensor to respond immediately; however, this setting is so sensitive that frequent alarms might occur. Set PULSE to 2 to slightly reduce the possibility of false alarms. Set PULSE to 3 for the maximum protection against false alarms. USING THE LOWER-SECTOR FILTER If you experience frequent false alarms caused by pets or small children, you can disable the lower sectors by using the supplied lower-sector filter. See "Sensor Coverage,". To install the filter, insert its side tabs into the slots on the sensor window. TESTING THE INSTALLATION NOTES: To verify proper operation, test the sensor once a week. This test sounds the alarm. After you mount the sensor, follow these steps to test the installation. 1. Set the motion sensor's ARM/DISARM switch to ARM. 2. Press AWAY on the base. 3. Enter the access code. The 30-second exit delay begins. 4. After 30 seconds, walk around the protected area and watch the sensor's indicator. It flashes when the sensor signals the control base. NOTE: If you arm the sensor immediately after you install the battery, the sensor does not detect motion for 2½ minutes. 5. About 45 seconds after the sensor signals the base, the base sounds an alarm. 6. Enter the access code at the base to stop the alarm. 7. After you test the sensor's installation, make sure ARM/DISARM is set to ARM for proper operation. MOUNTING THE SENSOR After you test the sensor's coverage and range, follow these steps to mount the sensor. 1. Using the sensor's bracket as a template, mark the positions for the four wood screws on the mounting surface. 2. Mount the sensor using the supplied wood screws. Note: To allow better access to the screws, loosen the sensor's collar screw to rotate the sensor's head and tilt it away from the screw hole. (CS 10/24/95)
