Thank you at last the first person on this site to actually know what I'm experiencing, this is exactly what I have researched over the last week! though I'm not sure dipping the 12V for 50ms is the best practice ? If this is by design I will see the same results on the new panel At least someone is in tune with the performance I am seeing on the elite 88 panel thank you

Not at all ! I do struggle a little when your making accusations that are clearly not true? I do not assume anything, everything in my working life is a process of elimination when problem solving, I have eliminated everything with this alarm panel and the problem in hand and shipped it back to the supplier I have be appreciative of peoples feedback, but do no appreciate rude people or arrogance, I'm an embedded engineer and apply logic and common sense, I have listened and performed every test suggested along with many of my own and come to the conclusion the panel is generating the dip in the 12V every 30 seconds I am now at the stage that I would like to compare a brand new panel and see if I get the same results Once again thank you to everyone who has been kind enough to give their input and feedback without being rude ?

No I did not buy from ebay ? I have shipped original panel back to company and got a full refund I have spoken to another company they say they get there stock from Texecom every three weeks I have now purchased from them a new panel (Premier elite 88) with latest firmware Lets wait and see if this panel performs any different

your not listening, please take time to read and analyse before posting. the switch mode power supply is 100% stable, 13.6V rock solid !!, there is no switching noise, it would be a **** psu if there was lol, the network 12V every 30seconds produced a dip for 50ms as it switches to battery test mode, more than likely done by a FET by design !! Try doing some research you may find your elite panel is doing the same lol, though you would never know with your multi meter ? as I keep saying everting is working, 100% please stop saying my kit is not working, as it’s starting to sound infantile it’s very common knowledge from Texecom these elite panels operate in this way very surprised your not aware for having so many years with Texecom alarms systems ????

Sorry I disagree … i have a OND, HND and degree in electronics i design advanced pcbs in Altium every day of my life designing embedded electronics with ARM F4 and F7 STM 32 processors. I program in embedded C utilising all the STM32 peripherals I2C, SPI, CAN, UART i use segger debuggers , Salae logic analysers, Fluke multimeters, keysight scopes i can assure you I know the basics principles and lot more aside lol yes every day I am more amazed at what a funny world it is ??? the alarm panel does not have lots of issues for the record, it simply dips the power at exact time periods of 50ms twice within a minute, not that you would be able to detect this with your multi meter ! I would also go as far to say the next elite 88 panel I purchase this week will be no different and act in exactly the same way not sure if you read the last text ? But even with 1 keypad and 1 alarm panel on less than a meter of cable, I get same results!!! it’s very clear from the scope that the alarm panel is being instructed to kill the 12v for 50ms and switch over to the 12v battery supply as part of the battery test, not that you multi meter would show this if you care to do the R&D you will find out about the elite panels all do this act as part of the battery test. not once has anyone mentioned this, Yes it is a funny world of funny people

Sorry I disagree ? I have some expensive Fluke 87 DVM meters although a superb multimeter, they will never see or detect a 50ms pulse or dip in the supply !! My 500mhz Keysight scope on the other hand nicely showed me the issue on the Network power lines, even when the alarm panel was disarmed. I'm sure a multi meter is great for 90% of the issues, but if you need to see fast acting transients, you will only ever see that on a oscilloscope due to the speed it can capture ? Alarm panel is now being shipped back, will order another one identical Thank you to everyone for your help albeit never really go to the bottom of the issue, can only think it was faulty or old hardware, I even took all the expanders off and just had the keypad connected and still had the same issue ??? The seller said this was normal and I should expect a dip in the supply ??? as that is what he experiences with the keypad and alarm panel ???

you have used CCA cable which isn't recommended what cable is recommended ? I have even tried individually screened CAT7 local to the Alarm to expander 1 & 2 no difference

why on earth is there a 140 network errors ???

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 regards I have only just started to evaluate texecom elite 88 so a little new to the scene what was the old texecom psu issues ?

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 ?

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 ???

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

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 ??

voltage at last expander

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,
