Texecom Elite 88 Expander Errors

[JOHNNYH]

hello all

 

have a new premier elite 88 texecom alarm system that I am evaluating, so far not too sure ??

 

I have one blue led keypad

 

5 expanders 8 XP

 

1  x 17 AH battery

 

1 x flasher board to update firmware

 

 

 

have configured the panel via wintext and flashed the latest firmware 6.05.03

 

2 expanders are wired close to the panel and three expanders are wired away from the panel on 15 meters of 8 core alarm cable (i use 3 cores for 12v and 3 cores for 0v, 1 core tx and 1 core rx)

 

 

 

there are 2 issues I have 

 

although the system all works fine, i keep getting expander network errors in wintex diagnostics?? why

 

1) I keep getting random incrementing network errors on various expanders when in wintex diagnostic mode 

 

i seem to get more network errors on the 2 expanders close to the panel ??? rather than the 3 on 15 meters of cable?

 

what on earth is going on! there should be zero errors when in diagnostic mode

 

the errors seem to increase when arming and disarming system ???

 

 

2) the second issue is this awful battery test the panel does every 30 seconds by dropping the 12v to the network so all devices blip/lose power for 50ms every 30 seconds

 

this can not be healthy for the electronics to constantly be interrupted on the 12v power lines even if it is for only 50ms ??

 

can this battery 30 second be turned off ?

 

i'm also wondering if the dip in the 12v every 30 seconds is causing network errors in the wintex diagnostics as i have 3 16ohm speakers on the expanders and i can even hear the audio from the speakers blip every 30 seconds when arming and disarming

 

 

Im just wondering if I have a faulty panel, but i have read that this is normal activity, I was hoping adding a battery would stop this blip of no 12v on the network but i still get it even with a brand new 17aH yuasa battery

 

any help would be very much appreciated as i may end up scrapping the whole system as i do not want network errors

 

 

thanks in advanced

Hi

1. That isnt normal

 

2. If everyone serviced systems this wouldnt be required however it is a good idea but i understand your concerns but isnt an issue for a healty system

 

your 16 ohms, they all on one or 1 per expander?

how are they powered?

if panel powered have you doubled or trebled up the power?

[JOHNNYH]

thanks for your reply

 

yes I have trebled up the power to each expander

 

I design electronics and circuit boards in altium pro PCB design software and fully understand voltdrop and earth loops etc.

 

Yes 1 x 16 ohm speaker per expander

 

 

there is no speaker on expander 2

 

1 x speaker on alarm panel

 

1 x speacker ex1, ex3, ex4, ex5

 

but im sure i get errors even without speakers

 

 

somethings not right ??

 

I have 5 speakers in total

 

everything powered from panel, no external power supplies

I'd assume both issues are connected, you shouldn't see large amounts of network errors. I'd expect to increase if more data is being transferred and will spill over to other network devices like you see tho.

If the voltage line is dipping to near 10v quickly but intermittently it will show as data corruption and not a tamper.

 

A list of things to consider:-

Is it CCA cable? Have you tripled the power? Voltage at the last expander? What are the network lights doing? Did you factory default when you flashed? What is the hardware revision of the panel and PSU? Checked for an earth loop?

 

Assuming the basics like cable and volt drop is fine, you can find out if these are related issues temporarily by simply ditching the +ve from the network and hooking up a clean power source like a fully charged battery from the other end of the network.

I'd say you have far too much kit on one PSU if these are powered devices.

Hi Thank you for your reply

 

Main board is D5112-02.03 Texecom 2011

 

not sure if this is old ?? it originally had firmware LS1 V5.02.01 now flashed to the latest firmware

 

power supply has a sticker saying HAD1000-6        31/01/20

 

network lights ....

 

red led on with brief flash off every 1 sec

 

green led more on with multiple off within each sec

 

yes cable is CCA CQR 8core

 

 

 

Yes i did do a power on while holding restore defaults before restoring my setting after flash, I also had this issues before updating flash firmware, nothing has improved since updating firmware

 

I seem to be getting mixed vibes about the dip in supply at 10sec and 40secs when the power defiantly dips for 50ms? people seem to think this is normal behaviour, but i can't stop the power from dipping ??

 

it always flickers the key pad leds briefly at 10secs and 40secs when the clock counts on the keypad design ??

 

I certainly would never interrupt the power to a microprocessor ARM design of mine as you would be asking for trouble ??

 

It would appear that the alarm main panel is instructing this behaviour at these two time periods every minuet so not sure if it is faulty hardware ??

 

I don't think there are any earth loops

 

the voltages at source are about the same at destination as i have tripled up power lines

 

I'm at a bit of a loss to be honest but not happy with such a simple setup and all these errors

 

I don't have any pir devices connected at present, so the total current is battery charging, 1 x keypad, 5 x expanders ?? not sure if its a bit high ?

 

even though i have spent a small fortune on all this kit, and was hoping to install a new alarm system to evaluate and connect the smart com etc. before offering to install this system, I may cut my losses now and ditch the lot as im starting to feel this kit is not fit for purpose sadly

 

been a few weeks setting it all up and getting familiar with it all but very disappointed with all this new kit and the end results 

 

Thanks for any feedback,

even if i only have two expanders i still get errors when arm and disarm ??? i wouldn't think by the total current draw i'm exceeding the limits of the power supply

 

but tomorrow could look into trying another 12v power supply, but would expect the same results as this always dips at regular time intervals

its almost like its being instructed to kill the 12v for a short period, why on earth i will never know as this can not be right ??

Not sure on your panel psu size but if you ditch all the spks then what do you get. 

I haven't looked in detail but what's the day current?

That's nice... did you read the installation book where it states the size of the psu & the current drawn by each texecom device ?

 

You have the main board, 5 expanders, 5 speakers & a keypad

 

I also assume you have an external bell(s) & powered detection

 

All powered by the panel....

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.
