  • What's Included
  • You don't have to sacrifice the security of your home because you own pets. With most ordinary motion detectors, a dog or cat can easy trip the sensor and cause a false alarm. With most cities cracking down on residential false alarms, you could face stiff fines, or be put on a "do not respond" list by local law enforcement.

    It Won't Confuse Your Pets for Burglars
    The Slimline Pet Immune PIR Motion Detector is an updated version of a motion sensor we've sold for years. This new model contains an advanced pet immune PIR detector element and lens system. Using TSI® (Target Specific Imaging) technology, the detector ensures immunity to pets weighing up to 40 pounds (18 kg).



    Reliable Operation
    The detector is also notable for its high stability, enhanced RFI protection (greater than 30 V/m), and high-temperature compensation for maximum "catch" performance and unique low-temperature compensation for optimum false-alarm rejection. The pyroelectric sensor is enclosed in a sealed chamber, protected from insects and air drafts.


    Adjustable Sensitivity
    For maximum flexibility, the sensor can be switched between one and three pulses. (A pulse is a detection by the PIR element.) This allows the sensor to be operated in a maximum sensitivity mode (one pulse) or is a less sensitivity mode (three pulse) where three specific detections are needed before the sensor signals the alarm panel that it has detected motion.

    Other Features
    Other features include a walk-test LED that allows to you to test the coverage area (the LED may be disabled during normal operation). A tamper detection circuit can be connected to your alarm panel to alert it in case anyone tries to open the sensor. Variable height adjustment allows the sensor to achieve maximum sensitivity when mounted on walls between 6 and 8 feet from the floor.

    Works with all hardwired alarm panels. Wires up as a normally-closed zone.

    The Slimline Pet Immune PIR Motion Detector can be directly screwed to the wall. However, if precise directional positioning is required, use these swivel brackets:

    • Swivel Wall Mount Bracket (#7481B1)
    • Corner Mount Wall Bracket (#7481B2)
    • Swivel Ceiling Mount Bracket (#7481B3)

    It works well and is unbelievably affordable. It does require a 12v.DC source and you do need to pay attention to the power polarity.

    Used it to cover a small bedroom 12x12. Installed in corner near ceiling. No pets. Good motion detection. Good quality for the price. No look down.

    Makes a little bit of a clicking sound when activated, and can go off multiple times within a few seconds. Detects well, works as designed.

    They work great. I installed two of them inside my friend's three car garage. I have them in my home as well. Sensitivity is just right, picks up all movement in coverage area, except rottweiler's movement. I have been installing alarms for about 5 years now and never had a problem with these. Read instructions and take your time. Freelance alarm installer, retired NYPD Detective.

    Sensors work well but the pet immune failed miserably with my 35 pound pit bull. Not one but all three detected the dogs movement at various heights and locations. Using both one and three pulse settings. I solved the problem by carefully apply black electrical tape covering the lense. By the time the sensors were working flawlessly without false pet detects I had the lense covered about 1/8 inch above center. This was applying the tape from the bottom of the lense up. This left the top of the lense open allowing human detection.
