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). The infrared receiver generally does not
detect room lights, indirect sunlight, or other light sources.

If anything moves through the beam and interrupts its path, the
alert triggers its built-in buzzer or activates a device connected
to the Normally Open (N.O.) or Normally Closed (N.C.) termi­nals. The connected device can be an alarm sounding device,
telephone dialer, or external alarm system.

CHOOSING A LOCATION

This alert is designed for indoor operation only. The distan ce
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.

Position the reflector so it correctly reflects the beam from the
alert. If you cannot mount the reflector directly across from the
