Honeywell IS312B Pet Tolerant Passive Infrared (PIR) Motion Detector with Swivel Bracket (replaces model IS215T)

Excellent pir sensor , easy to install, reliable operation so far with no false triggering . Recommend

Bought to replace an old PIR which had gone faulty and started triggering at random (suspect dirty relay contacts).There was some confusion as to whether this came with a mounting bracket - this one does.In the end I didn't use the bracket and just screwed the sensor direct to the wall.Installation is easy, there's nothing to set up except pet mode and LED disable (by jumpers).The alarm contacts are via SSR on this sensor, so there's no relay to fail like in my old one.Sensitivity is very good, it picks up movement straight away but no false triggers at all.

This is a typical PIR sensor, can be fitted into a corner but is a bit fiddly to install. It's been in use for a while now, no false alarms, and seems to work well. Not tested with pets though, we don't have cats or dogs here.

Purchased as a replacement for a sensor which had started giving false alarms - not sure if it's common but in my experience it seems sensors start doing this over time, but at least they are cheap to replace. The original PIR was a Honeywell IS215TCE and this a close equivalent at a good price. PIR sensors are generally all the same in terms of wiring so any would do but I like to try and not mix and match too much where possible, so this seemed a local choice for me.I fitted the original so was confident in replacing it, although if you are reasonably confident with basic electronics/wiring then it's an easy job. Would always recommend taking a photo of the original wiring before making any changes, as it's easy to forget what goes where, and you can always get back to where you started if needed.As expected the entry holes were different to the original but I had plenty of spare cable. This had the option of a ceiling bracket, but I didn't use that and just fitted directly to the wall in the corner. Like most sensors this had the option to enable/disable the LED and the pet sensor. I don't have pets so disabled that feature and left the LED enabled (which is the default).Once fitted, looks good and no more false alarms.

Bought as a replacement, original no longer available, slightly smaller than previous sensors but still fit original mountings

Good value for money

Not compatible with my system

I had a faulty PIR (motion) sensor which I detected via the walk test feature so knew it was this one. It was just detecting motion when there wasn't any so the alarm tripped when being set. We were just out of warranty so I decided to replace myself. Getting a pro would cost about £30 labour plus the PIR.This one says "Residio" on the bottom, the original said Honeywell but this is a company brand name change to their residential arm so same same.The best way to replace a faulty sensor is just to replace the circuit board, not remove the whole unit from the wall. I also isolated the Alarm on my consumer board but the sensors are only 12v DC1. remove the cover (small screw underneath and a press clip)2. Take a pic of the wires or remember the colour sequence3. Remove wires and circuit board (alarm will probably sound so put your PIN in4. Replace with new circuitboard and rewire5. Put the original cover back onStand back and admire your work, knowing you've just saved money :-)
