ˆ Features Your RadioShack Invisible Beam Entry Alert projects an invisible beam of infrared light across an area you want to secure. With your alert, you can easily detect an unauthorized entry through a doorway, window, or opening up to 50 feet wide. The alert includes a transmitter/sensor and a reflector. The transmitter sends out an invisible beam of infrared light which bounces off the reflector and returns to the sensor (if both units are aligned correctly).
Power Failure Alarm — triggers an external device when both AC power and a backup DC power limited source (if one is connected) are off. GENERAL INFORMATION Note: Some insurance companies provide a discount for homes protected by properly installed security and fire alarm systems. Check with your insurance carrier for requirements. Your Invisible Beam Entry Alert is designed to conform to federal regulations. To avoid problems, we urge you to read this manual completely before you install or use the alert.
Caution: Home security systems require a permit in some areas. Check with your local law enforcement agency before you install your system. ˆ Installation CHOOSING A LOCATION This alert is designed for indoor operation only. The distance between the alert and the reflector should be between 2.7–50 feet. Position the alert on a desk or counter top, within 6 feet of an AC outlet. The outlet should always be on (not controlled by a wall switch) so the alert will not be accidentally turned off.
alert, you can adjust the reflector angle up to 10° from center and adjust the beam lens up to 10° vertically and 5° horizontally. You can attach the reflector directly to a door so when the door is opened, the beam is interrupted. It is best to mount the alert and the reflector on parallel walls and at the same height, so the beam is aimed across a doorway or another opening. However, you can mount both units at different heights and then adjust the beam to compensate (see “Aligning the Beam” on Page 10).
MOUNTING THE ALERT You can mount the alert on a wall or on a desk using the supplied wood screws. Notes: • The supplied screws are suitable for wood surfaces only. If another type of surface is used, you might need other hardware. • Leave the cover off until after you have finished aligning the beam (see “Aligning the Beam” on Page 10). Before you mount the alert, loosen the screw on the door on the side of the alert, then open the door.
Or, follow these steps to mount the alert on a desk. 1. Place the alert 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. Thread the two supplied wood screws through the holes on the alert and into the mounting surface, then tighten the screws. 4. Plug the adapter into a standard AC outlet.
4. Remove the protective paper from the adhesive strips on the back of the reflector and press the reflector onto 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 the two supplied machine screws with attached washers. Note: Do not tighten the machine screws until after you adjust the reflector’s angle (see “Adjusting Sensitivity” on Page 11).
2. Turn SENSITIVITY clockwise to MAX. If the alignment is correct, the ALIGNMENT INDICATOR lights. The indicator turns off when the beam is interrupted or when SENSIVITY is set to MIN. If the ALIGNMENT INDICATOR does not light, the alert and reflector are not aligned properly. Readjust the angles of the reflector and/or the alert’s lens. 3. Replace the front cover on the alert.
• The alert might not detect a broken beam if you walk near the alert. If this happens, walk away from the alert to see if the ALIGNMENT INDICATOR turns off. • The alert might not detect a person who is wearing highly reflective clothing. 6. When you are satisfied with the sensitivity setting, close the door. CONNECTING OPTIONAL COMPONENTS You can connect an external siren (or device which operN.C ates when the beam is interN.
switch to ALARM, the external siren sounds when the beam path is interrupted. Caution: The external siren sounding device must be rated at 12 VDC, 0.5 A or less. 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 Phillips screwdriver to loosen the GND terminal screw. Then insert one of the conductors into the hole under the GND terminal and tighten the screw. 4.
Connecting Another External Device You can connect another external device (such as a phone dialer or an alarm system) instead of an external siren. Use Type CL2, 22-gauge wire to connect a device to the alert’s N.O or N.C terminals. If the beam path is interrupted with the mode switch set to ALARM, the alert activates the external device. Cautions: • The device must be rated at 12 VDC, 0.5A or less, and it must have its own power supply. • Do not connect a jumper wire to the OUTPUT 10–18 VDC 0.
5. 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 DC Power Limited Source Use type CL2, 22-gauge wire to connect a 12-volt 1-amp DC power limited source to the alert’s STANDBY terminal. When a backup DC source is installed, the alert automatically switches to DC source power during an AC power failure. 1. Separate about 2 inches of one end of the two-conductor wire. 2.
ˆ Operation USING THE ALERT 1. Loosen the screw on the door on the side of the alert, then open the door to expose the sensitivity and mode switches. 2. Set the mode switch to ALARM or ANNC. When the beam is interrupted in the ALARM mode, the external siren sounds (or another external device is activated) until the path of the beam is restored. To silence the alarm sooner, set the mode switch to TEST/OFF.
4. The built-in buzzer sounds and/or the external siren, dialer, or alarm system is activated. 5. To conserve the backup DC source’s power, set the mode switch to TEST/OFF as soon as you confirm proper operation. 6. Reconnect the AC adapter. POWER FAILURE ALARM When both AC power and the backup DC source are off, the alert triggers an external device (such as a phone dialer or an alarm system).
Problem Possible Cause Solution The reflector surface is Readjust and/or reposition the not set parallel to the front alert and/or reflector. of the alert. The sensor lenses are obscured with dust, lint, or other contaminants interfering with beam reception. Clean lenses using a nonabrasive lens cleaning solution and a lint-free cloth. ˆ Care Modifying or tampering with the alert’s internal components can cause a malfunction and might invalidate its warranty.
3. Press down on the top of the cover near the tab, and remove the cover. Fuse Holder Fuse Ribbon 4. Remove the fuse by pulling the red ribbon. 5. If the fuse is blown, wrap the new fuse in the red ribbon and insert it in the fuse holder. 6. Plug in the AC adapter and reconnect the backup DC source (if one is used). 7. Replace the cover and tighten the screw. Warning: For continued protection against fire, replace only with the same type and rating of fuse.
