Texecom Premier Elite 24 tamper on all zones

[job]

Hi, 

 

I have installed a Texecom Premier Elite for a client (I can't access the trade area as haven't made 5 posts) 2 years ago. 

 

I have the PIRs wired as EOL with standard 2k2 and 4k7 resistors. 

 

On Thursday night and Last night, I have had a notification of zone tampers. I went to the site on Friday and checked the log and wiring. The log shows that all zones had a tamper alarm at exactly the same time. The same thing happened last night too. 

 

I'm not sure what is causing all zones to tamper at the same time, has anyone seen this before or got any points that I should look out for. I don't install many alarms, mainly CCTV or wireless systems.

 

Can anyone suggest what I should be looking at?

 

Thanks in advanced.

Is there anything else in the log either side of this?

Are these panel zones or an expander?

What's on the system?

Just connected to the panel zones, no expander.

 

8 zones - all PIRs 

 

from memory nothing either side in the log.

 

what’s strange is that I perform an engineer reset and it clears the tamper, it’s. It like there is fault that prevents the setting of the alarm again

Picture of PCB and wiring ?

I don’t have a picture to hand. I will arrange and post once I’ve got one.

Tamper engineer reset maybe on...

Yes tamper engineer reset is on, but that’s means an engineer reset is required after a tamper event, that wouldn’t cause all the zones to have a tamper event at the same time.

 

I should have a photo this week of the PIR wiring and the PCB.

I wasn't suggesting this caused the fault, but it would lock the system out until you reset it.

I'd be using my meter checking all the voltages or maybe for signs of an earth fault or interference.

ac?

thanks for the advice, I will check all voltages and resistance measures.

 

I had thought it was an AC issue but just assumed that the battery with smooth it out.

 

Might have to replace the AC unit
