Hi

Two PIR+microwave detectors connected up to my Scantronic 9651 system have failed (1 about 9-12mnths ago, and another recently). They've lasted about 15 years based on the warranty label inside one of them, so that's pretty good. I can tell from the rooms they are in why they are PIR+microwave rather than just PIR.

So now I need to replace them. Are there any to recommend or to avoid ? Its a standard 6 wire system - power, alarm, and tamper circuits. Any recommendation for supplier ?

Also, will I have to put the panel into engineer mode to replace them ? I'd rather not since I don't have the engineer code and I'd rather not open up the panel and reset the whole system to factory defaults.



cheers,

BB

I couldn't find any make or model number, here's a pic I took of the internals (mostly to make sure i'd recorded the wiring somewhere besides a bit of paper. I assume they all look very similar inside.

I hope that 9651 is on user tamper reset or your in trouble.

It will not work now if it is on engineer reset.

pyronix equinox... what went wrong ? just getting an orange light only ? been changing a few pyronix detectors over the last few years, most common fault is the white light filter lens (white not clear) they go brittle and don't allow the ir to work.

I think the one in the conservatory has a single red light (i.e. the middle LED). The lens becoming brittle wouldn't surprise me, I expect the ambient temperature can get pretty high.

The other one has nothing at all - although the microwave element was a bit warm when I opened it up. It was working fine until this week, and just seems to have expired.

When I took the sensor apart, the panel alerted 'Global Tamper' and "Call Engineer". But when I put the user code it (and after I put the detector back together closing the tamper switch), the fault appeared to be cleared. I'm able to set the alarm (omitting the zones with the faulty detectors). So I guess I can swap the detectors out with some care.

I think I will order a couple of the Honeywell ones. Is there any benefit to getting the "pet tolerant" ones given there are no animals in the house ?

Thanks for all the replies so far.
