Review on High-Performance Dual Passive Infrared Motion Detector: Wired PIR Sensor for Residential and Commercial Burglar Alarm Systems, with Reliable Request to Exit Function by Mark Greenwood

Great product, bad review Must have been an accident or rather someone not knowing how to hook it up properly. I've been looking for a low cost IR sensor with normally open contacts for a long time, there are a million models out there with only normally open contacts, but this one has a simple jumper that allows you to change the output to normally open or normally open and has an additional set of tamper alarms. contacts, which makes it even better. I use it as a requirement for an exit sensor on the exit side of my doors for my access control system. The 12V power requirement is a perfect match for the rest of the gear, and the versatility of the pin configuration is amazing. I have already ordered more. The mounting bracket is great too, it has a removable ball head mount which allows for easy attachment and adjustment unlike most models which have to be placed against a wall or in a 45* corner.
