Overview

  • Dual passive infrared and microwave digital technologies provide long-term reliability
  • Easily customize detection range according to size of secured area (20, 30, or 40 feet)
  • Pet tolerant for animals up to 85 pounds

Essential Info

Install motion sensors that not only sense movement but also distinguish the difference between the motion of a human body and any other disturbance to help eliminate false alarms. The 85-Lb. Pet-Immune Dual-Technology Digital Detector combines a passive infrared (PIR) motion detector with a complementary active microwave sensor in a single unit for an accurate, false alarm-immune motion detector for maximum reliability. Ideal for use in residential and light commercial environments, the 85-Lb. Pet-Immune Dual-Technology Digital Detector won't be fooled by your pets and even allows easy customization for room size: When it's being installed, you can select the area to be secured from 20 to 40 feet.

  • More Info


    The 85-Lb. Pet-Immune Dual-Technology Digital Detector implements a variety of patented technologies, including FM Digital Signal Processing (FM-DSP), which adjusts automatically based upon the room size selected, thus optimizing both PIR and microwave performance within the protected area. The PIR motion detector employs a cylindrical lens with uniform detection sensitivity beginning at 1.8 feet (0.5m) away from the detector up to a distance of 40 feet (12m). "True Motion Recognition"™ with Fuzzy Logic algorithm (TMR™) allows the motion detector to distinguish between the true motion of an intruder and any other disturbances, which cause false alarms.

    An on-board motion event jumper determines whether 1 or 2 consecutive motion events will trigger an alarm to your security system. Additional features include a test input that permits switching the detector to the walk test mode remotely without removing the front cover. This motion detector is safe for use in homes with pets up to 85 pounds.

    If you won't be using this motion detector in an environment with pets, it is also available without the pet immunity feature.

    This is rated for a 85 LB Pet, but my 40LB dog sets it off.

    This device works fine within a wifi network. I've been using it that way for years.
    Michael -- atlanta, Ga   7/22/2009
    Beware - this device can not co-exist with a WiFi network. It basically acts like a WiFi jammer and blocks all wireless devices from connecting. If you have a WiFi network, get a normal PIR motion sensor, not one with microwave in it. Other than that, this sensor works well. Keep in mind the PIR part only covers up to 3 feet out. Head over to the visonic site for the tech docs for more.
    Steve -- novato, California   2/1/2009
    As with most motion detection devices, placement of this unit is important as it will affect its operation. After trying different wall and corner locations, I do not get any more false alarms with my 65 LB Labrador. Here is what I found. Stay away from corners at least 4ft. Mount no more than 8ft high. Point the sensor into the elongated side of a room rather than the short side and point the sensor into a clear area if possible without close or tall furniture in front of the sensor detection field. Hope that helps.

    I love this sensor, Very easy to install and Looks great! I have now had 3 of these motion sensors installed for about 4 Months and as of yet, I have been impressed that our Cats have not tripped this sensor. As for Distinguishing the differance between and animal of 85pds and a human I truly believe it works as even I don''t have a cat of 85 pds, but the cats have not trip my sensor but my child of 30 pounds has set off the sensor. It is Amazing! I will definitly be adding more of these specific sensors as I determine where they are needed. I have nothing but good to say about these sensors!
