Motion Sensor (490-0550) Installation Faxback Doc. # 6170 To wire the sensor to the alarm system's protection loop and 12-volt DC power, you need 24-guage or larger wire. Use a four-wire cable. Caution: Be sure your power source does not exceed 18-volt DC power. To connect your alarm system to the sensor, do the following: Note: The illustration shows a single-sensor connection. For multiple sensor connections. For multiple sensor connections, you must connect the sensors in series to the control unit's alarm terminals. 1. Carefully strip away about 4 inches of insulation from both ends of the cable. 2. Carefully strip about 1/2 inch of insulation from each wire. 3. Use a Phillips screwdriver to remove the screw on the sensor's base and slide off the base's cover. 4. With a screwdriver, punch out the wiring holes on the bottom of the base and route the wires through the holes. 5. Connect one end of the wires to the sensor's ALARM NC terminals and the other ends of those two wires to your alarm system's normally closed loop (NC) ALARM terminals. 6. Connect one of the other wire's ends to the sensor's DC 12V POWER - (negative) terminal and the wire's other end to your power source's negative terminal. 7. Connect the last wire to the sensor's DC 12V POWER + (positive) terminal and to your power source's positive terminal. Note: If you use this sensor with a multi-zone alarm system, you can turn off the zone the sensor is in and leave the alarm system's other detectors on. This lets you arm your system and walk around your house without triggering the system. MOUNTING THE SENSOR To mount the sensor on a wall or ceiling, do the following: 1. Using the sensor's base as a guide, mark the position for the screw holes. 2. Drill a 3/16 inch hole at each marked location, and insert the supplied plastic screw plugs into the holes. 3. Replace the base's cover. 4. Align the base's mounting holes with the two plastic screw plugs and insert the supplied screws through the base's mounting holes and into the plastic plugs. POSITIONING THE SENSOR Angle the sensor so its zones cover the chosen area and terminate on a solid surface. To angle the sensor, do the following: 1. Loosen the sensor's collar and the set screw. 2. Align the supplied angle gauge with the sensor so that the gauge's appropriate line is even with the sensor body's center line, as indicated: * If you are planning to angle the sensor toward the gauge's SIDE B, first line up the sensor's center line with the gauge's line-Y. * If you are planning to angle the sensor toward the gauge's SIDE A, first line up the sensor's center line with the gauge's line X. 3. Angle the sensor up or down as needed to cover a specific area. Then, tighten the sensor's collar and set screws. Cautions: * Do not force the sensor in either direction as this could damage the wires that connect the bracket to the sensor body. * Never angle the sensor more than -60 degrees in either direction. 4. Note how far you moved the sensor by referring to the gauge. The gauge's line that is now parallel to the sensor's line shows how many degrees you moved the sensor. Note: With the sensor body angled all the way up, the sensor's center line indicates -4 degrees if wall mounted and -2 degrees if ceiling mounted. SETTING THE SENSITIVITY The PULSE AND GAIN controls affect the sensor's sensitivity. Setting the Sensor's Range The GAIN control has three settings, which determine how much area the sensor covers. As you increase GAIN, you increase the covered area, as shown in the table. This control also affects the sensor's sensitivity to changes in temperature. As GAIN increases, the sensor's sensitivity increases. For example, when GAIN is set to 3/4, this sensor can detect the temperature difference within 5 degrees Fahrenheit. Setting the Sensor's Detection Three pulse settings determine how many zones the intruder must break and for how long, before the sensor triggers the alarm. As you increase the PULSE setting, you increase the number of zones and how long the intruder must break the zones before the sensor triggers the alarm system. * If an intruder would cross only one or two zones, set PULSE to 1. * In most cases where an intruder would cross several zones, set PULSE to 2. * If an intruder would cross a great number of zones or if the covered area has conditions that could cause false alarms, set PULSE to 3. This setting minimizes the chances or false alarms. Note: If you mounted and angled the sensor for its maximum range, use the 3-pulse mode. (RLR-02/25/94)
