What sort of premisses, I had heaps of problems with tampers at an engineering company. Ended up wiring all zones from EOL to double pole. This cured the tamper faults.

The m series/95 are ****. We moved off them about 5 years ago to galaxy and the faults disappeared overnight.

I guarantee you change that to a galaxy/premier and there would be no issue.

We are talking a lot about switching, but we could really use a panel that has built in analyzers as 75% of our domestic jobs are perimeter protection, company started with itec, mircotec, then aritech panels, again we never had these problems before,

Anyways update on the job, I found a 8way 110 transformer pluged in to the same circuit as the MSPSU was spurred from, the customer has said it was brought roughly the time the problems started!!!!! No tampers since it was moved, but it is still early days, fingers crossed and all that

And reply to paul.. The premises comprises of normal offices at the front and workshop at the rear, and they make massive plastic bags which fit inside of shipping containers to carry cheap wine around easily, so they use heated elements to seal the plastic,

the hkc and the siemens panels have built in analysers on the circuits

From the classic symptoms my vote us the power being switched if to the remote psu's, possible a rewire/alteration has occurred and has placed the mains feed to the expander psu on to a timed or lighting circuit, that gets turned of as they leave, or perhaps someone like new cleaners has decided suddenly to switch it off before leaving.

Biggest clue is if the time of activation after setting is about the same length of time within say 90 minutes on each occurrence. if you can get them to set it up in front if you, insist it is dine exactly as their habits and using the same person, then observe exactely what they do, if possible monitor the psu power ind lights.

One 'trick' if you have a spare zone at that expander, is to wire a simple psu to power of the expanders mains supply, use a spare relay, but don't fit any battery. attach springs to a zone programmed as 'on test'' so it only logs or prevents arming on any mains failures, but don't trip into alarm while set

Don't forget to go back before the 14 day auto off test timer kicks in though lol!

if you want all out on line analysing, then look at the Risco Prosys and Lightsys panels using BUS connected detectors, tells you every thing you need including voltages at device power terminals, so bar which way up the devices have been mounted lol!

as nice touch is if you run the tests it shows the results of that test and the previous test for direct comparison, old school engineers like me just thrive on that sort of diagnostic information

Had the Risco rep come here and demo their cloud app, WOW! a real game changer inho. Engineer has fuller access than client via phone, pc or pad, imagine walk testing or fault finding a large premisses using your phone or pad device as a remote keypad giving direct feedback without getting you neon screwdriver out - just a fantastic service aid.

but still not analysed vibro circuits?

i don't use many tbh, innate dislike for detection that can be triggered easily by outside influences, brought about by a misspent youth of many years dealing with inertia contacts and vibro's .

Not their yet i agree but i'd wager not far away, i heard a little dickIbird said wireless IP Detector Cameras are soon to be released, one thing you can say about risco, after years o stodgey plodding reliability and not changing design or SW that much, just look at them go now!

Oh ok.
