Essential Info

Don't wait for a burglar to enter your home before your alarm system goes off! Stop the crook BEFORE he breaks in with this combination Passive Infrared (PIR) motion detector and glassbreak sensor! Mount it in your ceiling and it will send an alarm signal to your security system when it detects motion, or when it hears the sound produced by the shattering of framed glass, including plate, laminated, wired, and tempered glass. It also offers 360° of PIR detection - enough to protect an entire room up to 20 ft. in diameter with just one unit. Superb false alarm protection rejects common bell or ringing sounds and provides immunity against RF, static and electrical transient, ensuring trouble-free operation for many years!


What's Included

  • 1x - Combination PIR Motion Detector and Glassbreak Sensor
  • 1x - Instructions
  • More Info

    The unit uses 2 zones of an alarm system, allowing the glassbreak zone to remain active while the motion sensor zone is disabled while you're home (arm/home mode).

    Very good quality, Good sensitivity, Having glass break and motion on the ceiling is great... Less obstructions on the walls.
    John Doe -- no, VA   4/17/2009
    You can install this on a 22/4 and still have the GBD and PIR on different zones just use RED for Aux Power, Black for all three negatives, and Yellow to a zone, and Green to a zone etc.
    PAUL -- charlotte, NC   2/21/2008
    It would be nice if you made a note this unit should use a 6-wire drop for independent functionality (I ended up wiring the sensors in series.
    DAVID -- bowling green, KY   5/14/2007
    This is a great item. It was very easy to install and the mounting holes and cable slots made the install very clean an efficient.
    MITCHELL -- goodview, VA   1/26/2007
    Sleek 2-sensor design looks more like a smoke alarm and keeps "wall acne" to a minimum.
