Texecom Elite 88 Expander Errors

[JOHNNYH]

Quote

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.

 

 

Thanks for the reply

 

even with only two expanders on the system on 2 meters of cable I still get the issues, I don't think this is too much kit on the system, the running current is 640ma ish

 

 

This issue is the alarm panel is glitching the supply lines to the expanders and keypad every 30 seconds ! that is the fault in a nutshel

 

YOU CAN NOT DIP THE SUPPLY FOR 50ms every 30 seconds and expect not to have issues, this should be a regulated 12V supply with NO interruptions

 

The alarm panel is being intructed to dip the 12V network supply every 30secs, I believe as part of the battery test / monitor but this is wrong and causing network errors!!

 

 

This is NOT random dipping of the PSU becuase of too much load, this is a consistant patterm twice every minute at exact 30 second time intervals!

 

 

We can keep talking about type of cable, too much on the PSU etc, but even with 1 keypad and 1 expander on 1 meter of cable the same thing happens!!

this is not a poor quality install, infact the attention to detail and quality of professional workmanship is more a professioanl install than most!

 

This is nothing to do with poor install or too much on the system, its a 50ms dip in power on the 10 second of time and the 40 second of time every minuet, i think its by design as part of the battery test, though this is a massive design flaw if it by design!!

 

All the hard ware has been purchased new, albeit the panel may have been old stock as the firmware was out of date ?? so it could be dated hardware

 

not sure if thats the issue with older hardware

 

thanks

Roughly  speaking the controls will power-

 

Its self & some detection devices

1 external sounder

1 keypad

1 extension speaker

1 communicator

 

Maybe a 2nd keypad or an expander with mostly contacts on it

 

It will probably need a 9ah battery to have the correct amount of standbay time

Well you came asking for help and your disregarding what you are told by people that work with this stuff every day.

I have told you how to rule this out and some things to check, there are further things that need ruling out but it's not normal.

To expand on MrH above, as a rule of thumb I would expect each power supply to have <~500mA quiescent per 7Ah battery to conform to BS EN; this is aside to your issue.

Thanks Guys

 

 

I am NOT disregarding people, I have OND/HND in electronic design, I design electronics every day of my life, I'm no fool and only choose to deal with the facts

 

I design in Altium PCB cad designer every day with ST32F7 ARM Processors, I fully understand the fundermentals of electronic design, power and embedded CAN bus systems.

 

 

I have provided the facts, this is not disregarding !

 

just simply looking to see if there are any other educated people out there that can apply logical comon sense from the facts provided or have experienced this issue themselves

 

 

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

 

 

 

The POWER SUPPLY is not dipping due to too much current being drawn, as I have alread explained,

 

 

the max current being drawn total is 680ma, there is a 1 amp fuse protecting the supply ! there is enough head room

 

I have used an my keysight oscilloscope to analyse what is going on with the network 12V supply and for 50ms at precise set times every minute the supply dips for 50ms

 

My Fluke 87 meter is too slow to show this 12V dip

 

The oscilloscope shows there is not much too power being drawn as the 12V supply on the keypad / network is 100% stable throughout, apart from two 50ms drops of power at set times every minute

 

 

The best advice would be to add large 4700uf capacitor in the network 12v, this will provide enough 12v Supply for the 50ms dip every 30 seconds

 

 

I will also add a quality 12V 6amp switch mode supply for the network, It will give much more headroom, but this is not the issue!!

 

 

The panel is turning off the 12V supply in some strange act that is causing this fault

 

Starting to question how good this kit is ???

I have already said what you have is not normal. Have you tried what I suggested...

There is still plenty more to prove, before I would consider hardware altho that's not to say you haven't actually got a duff panel/SMPS like I already said.

You keep saying you question the kit but if issues like this happened to other companies in the field people wouldn't be buying them...

I've got lots of it in the field, the oldest premiers are over 20 odd years,

But the 2.5A of power is at 12v ?

 

Chances are 5 extensions speakers will be almost all the current of the system !

Thank you guys for your feedback

 

I take onboard what you are saying

 

But... I have previously mentioned.... if I only have two expanders and 1 keypad with no speakers attached I have the same issues !!!

 

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

 

this equates to every 30 seconds, this then happens exactly at the same time every minute, I state again this issue I am seeing is not over powering the PSU

 

The alarm panel is instructing this action!

 

 

I have spoken to the company that sold this panel to me a few weeks ago today and explained everything I am experiencing , he said he experiences the same and this is totally normal especially with the large digit blue proximity keypad ?

 

I totally disagree, I don't believe this is normal, I do not want to see the 12V supply being interrupted at pre determined set times by the elite premier 88 alarm panel

 

This is not right and what I would expect to see! the very worst way I think about adding in future a new high quality, higher current PSU

 

I have decided to back this panel to the company as the is something not right somewhere ?

 

I will look to purchasing from another supplier 

 

1 keypad & 1 x expander should work fine with a stable 12V AUX supply. I clearly can not even achieve this 

 

But do really appreciate everyone's feedback

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

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

It's still seems like you have not tried what I suggested but whatever...

Send it back is the easy option.
