DUAL-ELEMENT INFRARED MOTION SENSOR
(490-0531)                 Features                   Faxback Doc. # 33462

Detects intruder's body heat and motion.

For use with an alarm system that has a normally closed security loop.

Small enough to be placed almost anywhere.

Dual-element circuit assures maximum sensitivity without annoying false
alarms.

Five-zone pattern covers rooms up to 20 x 35 feet.

Requires 12VDC at 24mA supplied by an alarm panel.

Multipurpose bracket allows corner or angle mounting.

Your Safehouse Infrared Motion Sensor is a passive motion detector designed
to be used with a central alarm system, such as Radio Shack's 49-450 or
49-470.  When it is used with a multi-zone system (such as 49-470), you can
bypass the motion sensor when someone is at home, while leaving other
sensors activated, thus preventing false alarms.

The sensor is triggered by changes in infrared heat waves. When an intruder
enters the area covered by this sensor, the alarm is tripped.  A built-in
tamper switch also sets off the alarm if an unauthorized person tries to
open the case.

Features

          Dual-element detector - extends the zones of coverage while
                                      reducing the likelihood of false
                                      alarms for better protection than is
                                      possible with a single-element sensor

                      Walk-test LED - Gives you a visual indication of the
                                      area covered by the sensor.

Complete mounting hardware included - Lets you quickly and easily install
                                      the sensor as part of your complete
                                      alarm system.

                      Tamper switch - Prevents unauthorized access to the
                                      sensor by triggering the alarm panel
                                      to sound an alarm if tampering is
                                      detected at any time.
