IS335 WIRED PIR Motion Detector, 40' x 56' by Honeywell

In these days of smart home automation, some of the wireless solutions don't meet the standards of the solid centurions of their wired predecessors. This device is one of the oldie-but-goodies. Not only reliable, easy to install, no batteries to change, looks good and all of that but will technically out-perform the wireless variety. Don't believe me? Check the instructions on the wireless offerings--actually read it--and you'll find that many will only trigger/report once every 3 minutes "to conserve batttery life". Motion detectors are devices that need to report every time a suspect moves into the area of protection. That isn't protection, its amusement known as Security Theater. Stick with wired tech whenever possible for lower cost, longer life and reliable performance. This is one of those devices.

Worked perfectly!!!!!

Bought a couple of these. After a few months of use, no false alarms and always picks up people

Worked perfectly, just note is a little smaller than old original ones you might be replacing

My old Crow Genius system monitor went out. I saw this sensor had the same 4 colored wires.I hooked the Black wire to -, Red wire to +, White to C, and Green to last spot( I guess S for Sensor)It worked! Very satisfied.

My old off-brand motion detector went bad after several years, so I bought this one because it was the same brand as my panel. Happy to report it works great and is actually smaller than my old one. Hopefully it'll last longer, but I won't know that for a while. So far, so great!

Seems to work OK with my 1990s Moose alarm system but it is poorly designed if you want to mount the top of the unit flush with the ceiling. The way the cover hinges at the top, it is not possible to mount it flush as made. If you install it flush like I did to conceal the wires coming from the ceiling, you will have to cut off the nubs on the hinge. No big deal but a hassle that is not necessary since they should have factored the fact that this might be mounted flush with the ceiling. And if you are like me, you don't realize this issue until the very end AFTER you have already drilled wall anchors, you will be very upset that you have to jury rig a fix to make it work.

I have a 25+ year old Brinks/ now ADT house security system. One night motion was detected by one of the three sensors in the house. I finally noticed that the light on the one sensor didn’t come on when approached. I replaced it with this sensor and it corrected the problem. Easy to replace and wire. I then bought two more in case any others wear out. I’ve only had it in a few weeks but is working well. Excellent replacement and quick delivery.
