muttsnutts Posted July 17, 2017 Report Share Posted July 17, 2017 (edited) Need some help if anyone is in the know. Just in the progress of moving alarm pir sensor and when connected it's setting the alarm off, tamper circuit is ok. When the sensor is disconnect the system is fine. Only have one pir on the system and one door connector. I'm not sure if to do with these "jumpers" in the pir sensor is causing the problem. Not sure what they do or how they were connected, one is labeled memory and the other p count. Can anyone shed light on what jumper goes where ? And if they cover two wires horizontally or vertically ? TIA. The system is a wired system and yes does go in tamper mode when taking apart but, these jumper things fell out when moving the sensor. So not sure what they do or if they could be causing such a fault. Edited July 17, 2017 by muttsnutts Quote Link to comment Share on other sites More sharing options...
HAYBURN Posted July 17, 2017 Report Share Posted July 17, 2017 Just a little advice you didn't say if it's a wired system or a wireless? on our wireless system, you have to key in the code and deactivate the anti tamper circuit. if you don't and you open the sensor the alarm will go off all the time.

Scottoj18 Posted July 17, 2017 Report Share Posted July 17, 2017 The old way of installing alarms is a method called 4 wire. A pair for alarm open and close. And a pair for tamper open and close. The alarm circuit goes back to the control panel and wires into a zone. The tamper circuit is a global circuit so this goes to all the devices starting at the panel, through all the devices the returning back to the panel. I would suggest wiring in just the alarm circuit to the pir and joining through the tamper circuit (just twist the cables together). Put the pir back together and see if it's works. If not them my best guess would be that you may have the alarm and tamper circuit cables mixed up. You would find this out by going to the alarm panel and checking what colour cables are wired in to the alarm zone. Hope this helps That a £80 please Quote Link to comment Share on other sites More sharing options...
Scottoj18 Posted July 17, 2017 Report Share Posted July 17, 2017 Without going in to to much detail p count stands for pulse count. Adjusting this changes how small movements trigger the pir or not. Quote Link to comment Share on other sites More sharing options...
