I'd be happier just buying a new PIR, I got the system fitted 15 years ago, so do I need to put in the engineer code, then turn off the 240 supply then change PIR?

They are Veritas Reflex,

Thanks, do I need to power down the alarm before changing the the PIR?

James, I see that the veritas 8 has an engineer hold off mode, could I swap the PIR thats giving me the false alarm with one of my good ones to diagnose it? How is the hold off activated? Thanks,

Ok, I guess I'll get a new PIR as the rest of system works fine the false alarm only started 2 days ago. If I do a walk test the sensor activates ok, but today after setting alarm and laeving the house the same false alarm happened within about 20 seconds.

Does it sound as though it could be a faulty PIR?

Hi, One of my PIR sensors is giving a false alarm whenever set to "FULL" on a Texecom Veritas 8 system. I've taken the cover off to make sure there was nothing inside the PIR setting off the alarm. Could this be a faulty sensor? Can I disable the PIR until the sensor can be replaced so that I can still use the rest of the alarm system. TIA.

After reading a few posts I'm not sure if there is a delay on full set. When I was testing it today I was turning it off after about 10 seconds, not to annoy my neighbours. When doing the sounder tests both internal and external sounders operate. Tomorrow I'll set it to full and activate it by opening a door.

I was altering the part settings a long time ago, so not sure if maybe I've changed something. Maybe I need to check if I've set to internals?

The bell sounder works fine if I go through the test steps in the manual. Not sure if there is a delay, I'll try again tomorrow, been trying for a while today so probably driving my wife and neighbours crazy.

Hi, should the external sounder go off instantly the alarm is activated. Today I returned home and my dog had set off the alarm. I have done a test to check that the sounders work, as per the operators manual, and it's all good. Then I set the alarm and opened the door, the internal sounder worked and the external strobe was flashing but the external sounder was not working?
