Aritech CS 250 / open zone

Edser

Hi Guys, hope you can help..

After recent power failure my system started showing 'open zone' on the hall PIR. When I walk in front of it there is no red light, and I've been inhibiting it manually before arming.

As it's been installed a few years I thought I would replace it, however when I installed the new PIR (same model) it now gives a tamper fault and still open zone.

It's wired as follows

1 - Red
2 - Black
3 - Yellow & Resistor1
4 - Resistor1 & Resistor2
5 - Blue
6 - Resistor2

Any ideas what's wrong or how to test/resolve?

That would indicate a problem with either the power cable going to the detector or the detector its self. You will need a meter to test for voltage at either end plus to test the cable. If you do have voltage then replacing the detector will fix the issue for you.

On the new PiR is the LED lighting when it detects movement.
If its wired correctly & the lid is closed correctly you should only get an open zone on a power fault & not a tamper condition.
If you could post up a pic of the new detector wired we can confirm everything is correct. Also bear in mind some new detectors come with built in resistors so read over the instruction carefully.

Thanks I'll check the voltages tonight. What should they be?

I've already tried replacing the PIR.

It's strange, on the normal setting it doesn't seem to light. On the high (more sensitive) setting it is nearly constantly on.

I'll check the instructions tonight and try to throw up a pic.

PS. PIR senor is an Intellisense IS-215t. I suppose the new one could be faulty too.

Thanks.

Around 12-14 volts dc would be the norm. If its lighting that should be ok.

The more sensitive you make it the more easier it is to pick you up walking in front of it. No harm in that. If you now have the light coming on can you test the open/close with no movement in front of the detector to see if it is now showing closed?

Hi Guys,

Thanks for all your advice. I got home too late to test last night and away now for the weekend, so I'll update next week.
