I assume this isn't one the old texecom PSU problems ? 

 

As I understand it the PSU comes from Elmdene, when they failed they just stopped producing voltage.

It is the control panel at set times causing this loss of power, 12V dipping for 50ms at 10 Seconds in to a minute and at 40 seconds in to a minuet

 

Compare it the ones o your the PSU2000XP's ?

If you know your stuff ? you will know the average person does not own Keysight oscillosope

 

Every possible measurement needed to commission and diagnose an intruder alarm can be done with multimeter

 

If you have property large enough to need 5 expanders & lots of expensive test equipment I would assume some with your qualifications & talent could earn more more doing your own job & pay a proper alarm co. to provide a working complaint system rather faff around wasting time & money doing it poorly.

if you run it only on the battery does the comms issues stop? if yes psu issue if no not psu issue

 

its definetly not normal

 

 

running on battery, the problem stops, 

 

no dip of 12V at every 10sec or 40sec 

 

the network supply is 100% stable until mains ins applied and the onboard PSU kicks in

I have only just started to evaluate texecom elite 88 so a little new to the scene

 

what was the old texecom psu issues ? 

-

 

 

PE 168, now much smaller system than it was for 20 years as a P168, each building has at least 1 psu, cables run under the public roads

spikes killed them, I've done PE24's between Edinburgh & London this yeat & don't go back

 

I also do Euro's & Orisec & don't have ay real issues with anything.

 

Al doesn't do Texecom using more exclusive equipment...

Battery load test is done daily with a delay in hours, the duration of this load test is in secs usually 10, it's not software!

You have too much kit on the system, you have used CCA cable which isn't recommended, it's a SMPS so will get choppy under heavy load.

It's my standard kit and it's not normal behaviour so your speaking to the wrong people.

It also sounds like you have bought the kit second hand or old stock and can't get it to work, there is a possibility you've been past off with old stock with a duff PSU being V6.

 

Either way there are clearly installation issues. The kit isn't designed for DIY installation and neither is the Smartcom.

You also need to use a proper multimeter not wintex if your diagnosing this stuff.

what cable is recommended ?

 

I have even tried individually screened CAT7  local to the Alarm to expander 1 & 2

 

no difference

I would normally wire intruder alarm data in belden, daisy chained, screened to cabinet (normally 4mm machine screw & nut, floating at last device

25+ year old cables, 20year old expanders, cable length, water in man holes, length of time its measured ?

 

its not a problem site,, so never tried to fixe it.

looks like a panel / psu problem then. If it stable without the mains.
