Invisible Beam Entry Alert (490-0316) Installation Faxback Doc. # 18317 We have designed your Invisible Beam Entry Alert to conform to federal regulations. To avoid problems, we urge you to read this manual completely before you install or use the Entry Alert. The Entry Alert is for indoor use only. This product is UL-listed to standard number UL639 for Intrusion Detection Units, and should only be used with UL-listed accessories. CHOOSING A LOCATION The Entry Alert is designed for indoor operation only, and the distance between the main unit and the reflector should be between 3-50 feet. For most applications, the main unit and the reflector are mounted on parallel walls so the beam is aimed across a doorway or other opening. It is best to mount the main unit and the reflector on parallel walls and at the same height. However, you can mount both units at different heights and then adjust the beam to compensate (see "Aligning the Beam", below). With the supplied desk mounting stand, you can put the main unit on a desk or counter top. You can attach the reflector directly to a door so when the door is opened, the beam is interrupted. Position the main unit within 6 feet of an AC outlet. The outlet should always be on (not controlled by a wall switch) so the Entry Alert will not be accidentally turned off. NOTES: The main unit and reflector should be high enough to keep someone from easily stepping over the beam. Avoid locations that will expose either the main unit or the reflector to direct sunlight, which could cause false tripping or damage the Entry Alert. CONNECTIONS To operate the Entry Alert, you must connect the supplied AC adapter to the main unit's terminals, located at the bottom of the unit. Use a Philips screwdriver to remove the screw on the top of the main unit. Pull off the cover to expose the terminals. You can also connect an external alarm (or other device which operates when the beam is interrupted) and an optional backup battery (as an alternate power source). Caution: Set the mode switch to TEST/OFF before making any connections. Connecting the AC Adapter Use the supplied two-conductor wire to connect the supplied AC adapter to the AC POWER 12V 830mA terminals on the main unit. NOTES: If you wish to connect an external alarm to the Entry Alert, cut a piece of wire approximately 4 inches long to use as a jumper wire before you use the remaining wire to connect the AC adapter. (See "Connecting an External Alarm" below.) Connect the wire ends with 3/8-inch stripped to the AC adapter, and the wire ends with 3/16-inch stripped to the main unit's AC POWER 12V 830mA terminals. 1. Use a Philips screwdriver to loosen the two screws on the adapter, then wrap a twisted wire end (with 3/8-inch stripped) around each screw. Tighten the screws. 2. Insert the other wire ends (with 3/16-inch stripped) into the holes under the main unit's AC POWER 12V 830mA terminals, then tighten the screws. 3. Plug the AC adapter into a standard AC outlet. Connecting an External Alarm NOTE: You must have the 4-inch-long piece of wire you cut before connecting the AC adapter as a jumper (see "Connecting the AC Adapter", above). If you connect an external alarm to the Entry Alert and set the mode switch to ALARM, the external alarm sounds when the beam path is interrupted. CAUTION: The external alarm sounding device must be rated at 12 VDC, 0.5 A or less. Use Type CL2, 22-gauge wire (such as Cat. No. 278-862 or 278-863) to connect an external alarm. 1. Separate about 2 inches of one end of the two-conductor wire. 2. Use a wire stripper to remove about 1/4 inch of insulation from the end of each conductor, then twist the loose strands. 3. Use a Philips screwdriver to loosen the GND terminal screw. Then wrap one of the conductors around the screw and tighten the screw. 4. Insert the other conductor into the hole under the main unit's N.O. terminal, then tighten the screw. 5. Connect the other end of the wire to the external alarm. 6. Separate the two conductors of the 4-inch jumper wire you cut before connecting the AC adapter (only one is used for the jumper). 7. Use a wire stripper to strip 1/4" of insulation from both ends of the jumper wire, then twist the loose strands. 8. Insert one of the jumper wire ends into the hole under the terminal at the operating point of the main unit's relay (between N.C. and N.O.), then tighten the terminal's screw. 9. Insert the other wire end into the hole under the main unit's positive (+) OUTPUT 12V DC 0.5 A terminal (labeled EXT OUTPUT), then tighten the terminal's screw. Connecting Another External Device You can connect another external device (such as a phone dialer or an alarm system) instead of an external alarm. If the beam path is interrupted with the mode switch set to ALARM, the Entry Alert activates the external device. CAUTIONS: Do not connect a jumper wire to the OUTPUT 12VDC 0.5A terminals. The device must be rated at 12 VDC,0.5A or less, and it must have its own power supply. Use Type CL2, 22-gauge wire (such as Cat. No. 278-862 or 278-863) to connect a device to the N.O. or N.C. terminals of the main unit. 1. Separate about 2 inches of one end of the two-conductor wire. 2. Use a wire stripper to remove about 1/4 inch of insulation from the end of each conductor, then twist the loose strands. 3. Use a Philips screwdriver to loosen the N.O. or N.C. terminal screws. Then insert the stripped wire ends under the N.O. or N.C. terminals and tighten the screws. 4. Connect the other end of the wire to the external device. Refer to the instructions in the external device's Owner's Manual to confirm connections and operation. Connecting a Backup Battery When a backup battery is installed, the Entry Alert automatically switches to battery power during an AC power failure. Use type CL2, 22-gauge wire (such as Cat. No. 278-862 or 278-863) to connect a 12-volt battery (Cat. No. 23-007 to the main unit's STAND-BY BATT 12V terminals. 1. Separate about 2 inches of one end of the two-conductor wire. 2. Use a wire stripper to remove about 1/4 inch of insulation from the end of each conductor, then twist the loose strands. 3. Use a Philips screwdriver to loosen the two screws on the main unit's STAND-BY BATT 12V terminals. Then wrap one conductor around the screw marked GND, insert the other conductor into the hole under the terminal marked 12V BATT., and tighten the screws. 4. Connect the other end of the wire to the battery. Be sure to match the polarity, as indicated by the markings on the terminals of the Entry Alert and the battery. NOTES: If there are no AC power failures, a fresh battery lasts about two years. During a power failure, if no alarms sounds, a fresh battery powers the Entry Alert for about 10 hours. Routing the Wires When you finish wiring the components to the screw terminals, route the wires through the wire slot at the bottom of the main unit. If you mount the main unit on a desk using the stand, route the wires from the screw terminals through the hole on the stand. MOUNTING THE ENTRY ALERT Position the main unit and reflector so the reflector correctly reflects the beam from the main unit. If you cannot mount the reflector directly across from the main unit, you can adjust the reflector angle up to 35° from center and adjust the beam lens up to 45° vertically and 5° horizontally. Mounting the Main Unit You can mount the main unit on a wall (using the four supplied wood screws), or on a desk (using the stand, two wood screws, and two machine screws, all supplied). NOTE: The supplied screws are suitable for wood surfaces only. If another type of surface is used, you might need other, appropriate hardware. Before you mount the Entry Alert, follow these steps. 1. Use a Philips screwdriver to remove the screw on the top of the main unit, then pull of the cover to expose the screw holes. 2. Set the mode switch on the main unit to TEST/OFF. NOTE: Leave the cover off until after you have finished aligning the beam (see "Aligning the Beam", below). Follow these steps to mount the main unit on a wall. 1. Using the main unit as a template, mark the position of the four screw holes on the selected wall location. 2. Drill four 1/8 inch holes in the marked positions. 3. Insert one of the supplied wood screws through each of the screw holes on the main unit and into the mounting surface, then tighten the screws. Or, follow these steps to mount the main unit on a desk. 1. Place the supplied mounting stand on a desk and use it as a template to mark the position of the two screw holes on the desk. 2. Drill two 3/32-inch holes in the marked positions. 3. Attach the stand to the desk with two of the supplied wood screws. 4. Mount the main unit on the stand by driving the supplied machine screws through the holes in the rear of the stand and into the unit. Mounting the Reflector Use the supplied mounting bracket, screws and adhesive strips to mount the reflector vertically or horizontally. 1. Using one half of the bracket as a template, mark the position for the two screw holes. 2. Drill two 5/32-inch holes in the marked positions. 3. Insert one of the supplied wood screws through each of the two screw holes in the bracket and into the mounting surface, then tighten the screws. 4. Remove the protective paper from the adhesive strips on the back of the reflector, and attach the reflector to the other half of the bracket. 5. Attach the half of the bracket with the reflector to the half you mounted on the wall in Step 3, using two of the supplied machine screws (with attached washer). NOTE: Do not tighten the machine screws until after you adjust the reflector's angle (see "Adjusting the Reflector's Angle", below). ALIGNING THE BEAM After you mount the main unit and reflector, you must make sure they are aligned correctly. 1. Check the angle adjustment by looking into the hole on the side of the main unit's mirror box, above the lens head. NOTE: If you cannot look into the hole on the mirror box from one side, slide the box out, turn it upside down, and reinstall it with the round hole facing toward the front. Then look into the mirror box from the other side. You can leave the mirror box in this position. If you do not see the reflector through the hole, readjust the angles of the reflector and/or main unit's lens (see "Adjusting the Reflector's Angle" and "Adjusting the Main Unit's Lens Angle", below). 2. Replace the front cover on the main unit and tighten the screw on top. 3. Turn SENSITIVITY fully clockwise to MAX. If the alignment is correct, the ALIGNMENT indicator lights. The indicator turns off when the beam is interrupted or when SENSITIVITY is set to MIN. If the ALIGNMENT indicator does not light, the main unit and reflector are not aligned properly. Readjust the angles of the reflector and/or main unit's lens. Adjusting the Reflector's Angle You can adjust the angle as much as 70°. To adjust the reflector's angle, turn the half of the bracket with the reflector attached to it until the reflector is at the desired angle, then tighten the screws. Return to Step 2 of "Aligning the Beam," above. Adjusting the Main Unit's Lens Angle You can adjust the lens as much as 45° vertically and 10° horizontally. Follow these steps to adjust the lens angle vertically. NOTE: Remove the front cover from the main unit, if necessary. 1. Using a Philips screwdriver, loosen the screw on each side of the lenses. 2. Move the lens head to the desired angle. 3. Return to Step 2 of "Aligning the Beam," above. Follow these steps to adjust the lens angle horizontally. NOTE: Remove the front cover from the main unit, if necessary. 1. Insert a Philips screwdriver through the square hole on top of the main unit and loosen the screw under the hole. 2. Move the lens head to the desired angle. 3. Return to Step 2 of "Aligning the Beam," above. ADJUSTING SENSITIVITY After you align the beam, adjust SENSITIVITY to ensure reliable performance and minimize the chance of false alarms. 1. Loosen the screw on the door at the right side of the main unit and open the door to expose the sensitivity and mode switches. 2. Set the mode switch to TEST/OFF. 3. Turn SENSITIVITY fully counterclockwise to MIN. The ALIGNMENT indicator turns off. 4. Turn SENSITIVITY clockwise until the ALIGNMENT indicator lights. 5. With the mode switch still set to TEST/OFF, interrupt the beam by walking between the main unit and the reflector. The ALIGNMENT indicator turns off. NOTES: If you adjust SENSITIVITY too close to MAX: The Entry Alert might not detect a broken beam if you walk near the main unit. If this happens, walk in the area away from the main unit to check if the ALIGNMENT indicator turns off. The Entry Alert might not detect a person who is wearing highly reflective clothing. 6. When you are satisfied with the SENSITIVITY setting, close the door and tighten the screw to secure it. (CS 10/23/95)
