12V DC Wired Motion Detector PIR Infrared Sensor for Alarm System with Silent Relay

Ordered Friday night about 7pm and arrived Sunday at 12pm. Easy install(power wires and 2 signal wire) and avoided paying the alarm company $90 for replaces.

Just spend the extra $5 on a name brand like Bosch or Honeywell.The instructions are in poor english and the photos in the instructions don't match the circuit board (tamper block and alarm block reversed). Worst of all- even though the red LED flashes when motion is detected, the alarm block isn't triggering the alarm.I spent a couple hours trying to figure out why I couldn't get my system to work, when all along it was this sensor that was defective.

I bought 3 of these about a month apart, the original works great; unfortunately the other 2 do not. The non operational units detect motion but will not send trigger to alarm. I have spent hours checking fault and checking pin placement, it's the units! Unfortunately I ordered these months in advance to wiring the alarm, so I have missed the return window.

We finally got to a point where we could install this and it does not work. All this time for a faulty detector. Very frustrated. Glad they dont have more. Don't waste yourMoney.

Does not work well, range is inadequate (placed 8ft in air at end of hallway. Doesn't trip until I am about 4 ft from it. Hallway is 15 ft long)

bought 2. One would not work at all. The other triggers false alarms daily. Badly made product. Lousy instructions. Buy something else.
