Your RadioShack Invisible Beam Entry Alert projects an invisi-
ble 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.) termi-
nals. The connected device can be an alarm sounding device,
telephone dialer, or external alarm system.
TEST/OFF Mode — lets you easily test the alert.
ANNUNCIATE and ALARM Modes — let you set the alert to
automatically sound the built-in buzzer or trigger an external si-
ren or other device (such as a phone dialer or an alarm system)
when the beam is interrupted.
Sensitivity Control — lets you adjust how much activity will
trigger the alarm.
External Device Connection — includes a single 10–18 volt
DC power output to provide power to an external security de-
vice.
