Passive Infrared Alarm (490-0320) Installation Faxback Doc. # 18578 CAUTION: Be sure to leave ALARM (on the back panel) set to OFF during installation. CHOOSING A LOCATION Where you place and how you position the alarm affects the sensor's coverage. Use the following suggestions for choosing a location and for positioning the alarm as desired for your security needs: Choose a location that is near an AC outlet and where you can position the alarm's sensor to cover entrance areas, such as front and back doors or windows. You can turn the sensor window right or left to cover the areas you want. For reliable operation, aim the sensor toward solid surfaces, such as a wall or ceiling. The sensor uses the surface as a steady temperature reference. If pets do not enter this area, you can aim the sensor toward the floor. Place the alarm where an intruder would move across several zones. The sensor is most sensitive to motion across its zones and less sensitive to motion toward or away from the zones. For maximum coverage, choose a location that is 6 feet or more above the floor. At 6 feet, 7 inches off the floor, the sensor reaches its maximum range. At this location, the upper zones cover up to 30 feet from the sensor with a 40 feet, 10 inch span at 30 feet. The lower zones cover up to 10 feet from the sensor with a 10 1/2 foot span at 10 feet. CAUTION: When you choose a location, avoid the following conditions that could cause false alarms: Where sunlight shines directly on the sensor Where heat sources, such as space heaters or radiators, are located Where strong drafts of air hit the sensor, such as from a central heating vent or an air conditioner Where any openings constantly expose the sensor to outside elements Where animals would cross zones Where the sensor is aimed at heating or air conditioning vents or ducts, an exterior metal wall, a refrigerator, exposed light bulbs, fireplaces, exterior windows, or anything air might move NOTES: Depending on where you place the alarm, the area directly under and in front of the sensor might not be covered. Never cover or try to change the color of the sensor window. If the sensor's lower zones must be aimed at areas that might cause false alarms, cover the lower portion of the sensor with the supplied mask. Remove the mask (labeled LOW BEAM CUT FILTER) from the alarm's bottom cabinet by inserting a pointed object such as a paperclip through the sensor window slits. Then insert the mask's tabs into the sensor window's slits. ADDING OPTIONS You can add optional devices to the alarm for more security and convenience. These options include back-up battery power, an external alarm, an automatic telephone dialer, and a remote switch (available at your local Radio Shack store). If you choose not to add any other options, we do recommend that you install batteries so the alarm functions even during a power failure. Then proceed to "Connecting Power," (SEE BELOW). Adding Back-Up Battery Power If you install batteries (not supplied), the alarm automatically switches to battery power if AC power fails. The alarm uses eight C-size alkaline batteries, such as Radio Shack's Cat. No. 23-651. The alarm can operate from the batteries for about 40 hours with no alarm sounding, or for about two full 5 minute alarm cycles. We recommend you install batteries to ensure continued operation and protection. Follow these steps to install batteries. 1. Use a Philips screwdriver to loosen the two screws that secure the battery compartment cover. 2. Insert the screwdriver into one of the screw holes. Then lift up the cover with the screwdriver. 3. Place the batteries in the compartment, following the polarity symbols (+ and -) as marked inside the compartment. 4. Replace the battery compartment cover and tighten the screws. When all the batteries are correctly installed, the ALARM/BATT TEST indicator starts flashing and the alarm begins to warm up. See "Warming Up the Sensor" in "Connecting Power," (SEE BELOW). NOTES: Test the batteries once a week. If the ALARM/BATT TEST indicator does not light when you press and hold down ALARM/BATT TEST, replace all the batteries and check the fuse. See "Replacing the Fuse." (Refer to Faxback Doc. # 18579, Operation). Remove the batteries if you unplug the alarm for a week or more. Replace the batteries every two years even if there are no power failures. Clean the battery contact points with a cloth every few months. Adding an External Alarm You can connect an external alarm to the EXT terminals on the back of the alarm. Use only a 12 - 16 volt DC alarm that requires no more than 1 ampere of current, such as Cat. No. 49-488. NOTE: If you want to silence the internal alarm when you use an external alarm, remove the jumper between the INT JUMP terminals. Loosen the screws on the terminals, remove the jumper, and re-tighten the screws. Keep the jumper for future use. Adding a Remote Switch You can add a remote arm/disarm switch to the alarm so you can arm/disarm it from a remote location. Use a remote switch such as a Digital Keypad or a Remote Key Plate (Cat. No. 49-524) and Locking Contact Switch (Cat. No. 490-0535 or 490-0537). Do not use a momentary type remote switch. 1. Disconnect the jumper from the REMOTE SWITCH terminals on the back of the alarm. NOTE: Leave the jumper in place if you do not want to use a remote switch. 2. Connect a remote switch to the REMOTE SWITCH terminals by following the instructions provided with the remote switch, and connect an LED as indicated. 3. After you complete all connections and testing, set ALARM to ARM so you can use the remote switch (see "Turning on the Alarm"). (Refer to Faxback Doc. # 18579, Operation). Adding Remote Keypad (Cat. No. 490-0535) 1. Remove jumper from the keypad. 2. Set latch to IN. 3. Connect keypad to terminals 1/2 on the Alarm. 4. Position red LED to terminal 3 and negative of red LED to terminal 2 on alarm. Adding an Auto-Dialer You can add other devices, such as an automatic telephone dialer, to the alarm's terminals. These terminals do not supply power, but act as a switch for the device's own power supply. The terminals turn on the device's power supply when the sensor detects an intruder and turns off the device's power supply when the alarm stops. Any device you plan to connect to these terminals must have its own power supply and the rating of the device must not exceed 24 volts DC, 1 amp, or 130 volts DC 50 mA. Use the N.O. (normally open) terminals as needed for the devices you want to connect. NOTE: If a telephone dialer is connected to the alarm, do not program it to place a call to your police department unless your police department allows this. This might be permitted by some low enforcement agencies. If not, you can program the dialer to call a friend or private security agency who, if needed, can call the police. CONNECTING POWER Plug the alarm's power cord into a standard AC outlet. Do not connect it to a receptacle controlled by a switch. The AC POWER indicator (on the back panel) lights. Warming Up the Sensor When you first install batteries or plug the alarm into AC power, wait about 90 seconds before using or testing the alarm. Securing the AC Power Cord The supplied plastic clamp is designed to help prevent the alarm's AC power cord from being accidentally unplugged from the AC outlet. Follow these steps to connect the clamp and cord to an AC outlet. 1. Turn off power to the outlet at the fuse box or breaker panel. 2. Follow the instructions for the type of outlet you want to use: For a standard, household, two plug outlet, remove the screw that secures the outlet cover plate. Then secure the plastic clamp and the outlet cover plate to the outlet by reinstalling the screw. For a four plug outlet (such as in basements, garages, or workshops), remove the screw that secures the corner of the outlet cover closest to the power plug. Then secure the plastic clamp and the outlet cover plate to the outlet by reinstalling the screw. 3. Restore power at the fuse box or the breaker panel and test the alarm. (JC/ir--09/24/96)
