180 Degrees Passive Infrared Motion Sensor (490-0208) Installation Faxback Doc. # 17224 READ THIS BEFORE INSTALLATION Before you install the motion sensor, read the entire "Installation" section. Decide where to mount the motion sensor and where to route the wires. NOTES: This motion sensor is for indoor use only. The sensor does not have an internal alarm sounding device or power supply. It is designed for use with a UL-listed central alarm panel system that provides a minimum of 4 hours of standby power. The sensor requires 9- to 16-volt DC power at 25 milliamps. If your alarm system's terminals do not provide this power, you need an additional power supply. Your local Radio Shack store sells a wide variety of suitable alarm systems and power supplies. The sensor's operating temperature is from 32 to 104 degrees F (0 to 40 degrees C). If you use this sensor with a multi-zone alarm system, you can turn off the zone where the sensor is and leave the alarm system's other zones on. This lets you arm your system and walk through the zone where the sensor is without triggering the alarm. CHOOSING A MOUNTING LOCATION IMPORTANT: Do not mount the sensor until after you wire it and check the connections. You can mount the sensor or on the ceiling, a wall or any flat surface. For reliable operation, choose a location where the sensor has a solid surface (such as a wall or ceiling) to use as a steady temperature reference. If an intruder passes between the sensor and the surface, the sensor detects the temperature change. This sensor is more sensitive to movement across its zone and less sensitive to movement directly toward or away from the zone, so choose a mounting location (such as a hallway wall) where an intruder must walk across the protected zone. Avoiding False Alarms When you choose the sensor's mounting location, avoid locations where: Sunlight shines directly on the sensor The sensor will be exposed to humidity or rain Any opening (such as a vent, window, or door) constantly exposes the sensor to outside elements Sources of heat (such as space heaters, radiators, exposed light bulbs, fireplaces, or refrigerators) are in or near the protected zone. Strong drafts of air (such as from a central heating vent or an air conditioner) hit the sensor The sensor is aimed at an exterior metal wall NOTES: The sensor's ability to detect temperature changes decreases when the reference surface and an intruder's body are almost the same temperature. The sensor must be mounted at least 6.6 feet (2 meters) above the floor, except when using the pet lens. (See "Selecting the Lens.") SELECTING THE LENS The sensor has four different lenses. It comes with the wide angle lens installed. If you decide to use another lens, see "Replacing the Lens." NOTES: The wide angle and long distance lens sets each contain two lenses, one for long distances and the other for shorter distances. The pet lens does not detect movement from floor level to about 18 inches off the floor (when mounted at the height specified in the table). Use it to prevent accidental triggering by small animals. The curtain lens does not detect movement to one side, so you can avoid accidental triggering by blowing curtains. Use this table to select the proper lens for the coverage you need. The lens number is marked on the tab of the lens. ┌──────────────┬─────────────────────────────────────┐ │ LENS NO. │ 1 │ ├──────────────┼─────────────────────────────────────┤ │ Type │ Wide Angle │ │ Mounting │ 6.6 Feet │ │ Height │ (2 Meters) │ │ Zone's │ 1st Zone 2nd Zone │ │ Coverage │ 110 degrees 180 degrees │ └──────────────┴─────────────────────────────────────┘ ┌──────────────┬─────────────────────────────────────┐ │ LENS NO. │ 2 │ ├──────────────┼─────────────────────────────────────┤ │ Type │Long Distance │ │ Mounting │ 6.6 Feet │ │ Height │ (2 Meters) │ │ Zone's │ 1st Zone 2nd Zone │ │ Coverage │ 20 degrees 110 degrees │ └──────────────┴─────────────────────────────────────┘ ┌──────────────┬─────────────────────────────────────┐ │ LENS NO. │ 3 │ ├──────────────┼─────────────────────────────────────┤ │ Type │ Pet │ │ Mounting │ 4.3 Feet │ │ Height │ (1.3 Meters) │ │ (Zone's │ 110 degrees │ │ Coverage) │ │ └──────────────┴─────────────────────────────────────┘ ┌──────────────┬─────────────────────────────────────┐ │ LENS NO. │ 4 │ ├──────────────┼─────────────────────────────────────┤ │ Type │ Curtain │ │ Mounting │ 6.6 Feet │ │ Height │ (2 Meters) │ │ Zone's │ 20 degrees │ │ Coverage │ │ └──────────────┴─────────────────────────────────────┘ Using the Curtain Lens The reflecting mirror in the lens gives the sensor a narrower coverage area. You can use the curtain lens with or without the reflecting mirror. (See "Removing the Reflecting Mirror." Curtain 'A' (without the reflecting mirror) covers these areas: Top view Side View Curtain "A" Curtain'B' (with the reflecting mirror) covers these areas): Top View Side View Curtain "B" WIRING THE SENSOR To wire the sensor to the alarm system's protection loop and to connect it to 9- to 16-volt DC power, you need 24 gauge or larger six-wire cable (Radio Shack Cat. No. 278-874). CAUTIONS: Be sure your power source does not exceed 16 volts DC. Disconnect power from the main control unit before you connect the sensor to it. Follow these steps to connect the sensor to your alarm system. NOTE: Refer to the first illustration for an example of a single-sensor connection. If you use more than one sensor, you must connect them to the control unit's alarm terminals in series. Multi-Sensor Connection 1. Carefully strip away about 4 inches of outer jacket insulation from both ends of the cable. 2. Carefully strip about 1/2 inch of insulation from both ends of each wire. 3. Use a Phillips screwdriver to remove the screw on the sensor's upper case, then lift off the case. 4. Remove the screw that holds the printed circuit board (PCB) in place, then lift off the PCB. 5. Use a screwdriver to knock out the elliptical hole on the lower case, then route the cable through the hole. 6. Loosen the screws on the sensor's terminals to connect the wires. 7. Connect the wires from the sensor's T1 and T2 terminals to the alarm system's Panic (Normally Open) terminals, then tighten the screws. 8. Connect the wires from the sensor's T3 and T4 terminals to the alarm system's Normally Closed (N.C.) terminals, then tighten the screws. 9. Connect the wires from the sensor's T5 terminal to the alarm system's 12-volt positive (+) terminal and connect the sensor's T6 terminal to the alarm system's 12-volt negative (-) terminal. Then tighten the screws. NOTES: Check to ensure the terminal connections are correct and secure before you continue with the installation. Do not replace the PCB or the upper case until after you mount the sensor in the selected location and adjust the detection distance. After you complete the wiring, paste the single-sided adhesive pad over the wiring hole to prevent dust, dirt, and insects from getting in. Do not apply power to your alarm system until you replace the sensor's upper case (after you adjust the detection distance). Setting the Pulse Count The pulse count setting determines how many zones the intruder must cross and how long the zones must be violated before the sensor triggers the alarm. NOTE: You must set the pulse count to one when using the curtain lens. Lift the jumper off one pin of P2 to set the sensor to one-pulse count mode. The sensor triggers the alarm system when the first zone is violated. Leave the jumper on both pins of P2 to set the sensor to two-pulse count. The intruder must violate two zones before the alarm is triggered. MOUNTING THE SENSOR You can either mount the sensor with the supplied double-sided adhesive pad, or follow these steps to use the supplied screws (or other suitable mounting hardware). NOTE: The adhesive pad blocks dust, insects, and other debris from getting into the wiring hole. 1. Using a screwdriver, knock out the mounting holes on the sensor's lower case according to the selected mounting location. Location Knock Out Flat Wall M5 and M6 Corner M1 and M3 Ceiling Edge M2 and M4 2. Using the holes as a template, mark the mounting location with a pencil. 3. Drill two starter holes into the marked location. Then hammer the supplied screw anchors into the wall, or use other mounting hardware suitable for the mounting surface. NOTE: The supplied screw anchors are suitable for sheetrock and masonry surfaces. 4. Align the mounting holes on the sensor's lower case with the supplied screw anchors (or suitable mounting hardware) and secure the sensor to the mounting location with the two supplied screws. NOTE: Do not replace the PCB or the upper case until after you adjust the detection distance. Replacing the Lens 1. Use your fingers to gently push in both ends of the lens until the lens and its locking frame pop out from their place in the cover. 2. Install the selected lens with the polished side out. Align its tab with the recess on the upper window, then gently push in the sides for the lens to snap it into place. 3. Push the lens' locking frame in to snap it in place. Removing the Reflecting Mirror If you want to use the curtain lens and select curtain A, follow these steps to remove the reflecting mirror. 1. Grasp the upper and lower flat portion of the reflecting mirror, then gently lift it from the PCB. 2. To prevent reflections from the sensor's internal components from affecting the sensor, put the supplied rubber ring over the sensor. ADJUSTING THE DETECTION DISTANCE The scale setting on the PCB's left edge, along with the lens you select, determines the detection distance. Lens 1 Scale Wide Angle Setting Zone 1 Zone 2 Feet (Meters) Feet (Meters) 1 16.4 (5) 3.3 (1) 2 23.0 (7) 6.6 (2) 3 26.2 (8) 9.8 (3) 4 32.8 (10) 13.1 (4) 5 39.4 (12) 16.4 (5) Lens 2 Scale Long Distance Setting Zone 1 Zone 2 Feet (Meters) Feet (Meters) 1 39.4 (12) 3.3 (1) 2 45.9 (14) 6.6 (2) 3 52.5 (16) 9.8 (3) 4 59.1 (18) 13.1 (4) 5 65.6 (20) 16.4 (5) Lens 3 Lens 4 Scale Pet Curtain Setting Zone 1 Zone 1 Feet (Meters) Feet (Meters) 1 39.4 (12) 39.4 (12) 2 - - 3 - - 4 - - 5 - - NOTE: The detecting distance is measured at the operating temperature of 68 degrees F (20 degrees C). Follow these steps to adjust the detection distance. 1. Use the tables to determine the scale setting for the lens you installed. 2. Insert the PCB between the two PCB holders on either side of the lower case. Align the desired scale setting (1-5) with the top of the PCB holder on the left side of the case and the bottom of the holder on the right side of the case. 3. Secure the PCB with its screw. NOTE: Before replacing the upper case, be sure the jumper is on both pins of P1. If the jumper is off one pin of P1, the test indicator will not light. 4. Replace the upper case by aligning the latch on the bottom of the upper case with the recess on the lower case, then press the upper case onto the lower case and secure it with its screw. 5. Turn on your alarm system's power and wait about 1 minute to let the sensor warm up. TESTING THE SENSOR Follow these steps to test the sensor. 1. Disarm the alarm system. 2. Confirm that the protected area is clear of people, pets, and any of the potential problems listed in "Avoiding False Alarms." 3. Take at least five steps across the protected area. Repeat this from four different directions. See if the sensor's test indicator lights within the first few steps. The sensor should detect movement in at least three out of the four directions you walked. NOTES: When the two-pulse count is set, at the first trigger, the indicator dimly lights. At the second trigger, the indicator fully lights up. When the one-pulse count is set, the indicator fully lights up as soon as it is triggered. 4. Stand clear of the protected area, but where you can see if the test indicator lights. If the indicator lights, find and remove the cause of the false alarm. (See "Avoiding False Alarms.") 5. Remove the sensor's upper case. The alarm system's panic alarm sounds. 6. Lift the jumper off one pin of P1 so the test indicator will not light. (This prevents an intruder from knowing whether or not the sensor is operating.) Replace the upper case and secure it with its screw. 7. Arm the alarm system.
