Fire alarm panel. Don’t recognise fault code

[littlespark]

The big stately home I’ve been working in has an EMS 5096 alarm system with over 100 detectors and 3 (that I know of) panels.
All detectors are battery powered and radio back to its closest panel. All panels are also radio linked together.

They get the odd fault code which is usually a flat battery. They can change the battery’s and reset the system themselves… but the other day they got a message that won’t reset.
The screen says fault and something like “Radio Net 03”

From what I’m guessing, it’s the radio link to the 3rd panel….. but I can’t find anything online on how to either reset it or investigate what the problem is.

Already downloaded that page, buzz. Doesn’t explain how to fix the problem.

I could, following the instructions, disconnect the panel from the system, then try to re-enable…. Wait and see.

The manager had contacted their alarm company that supposedly look after the system, but they said all they would do would be take a couple of days to test every sensor, with no guarantee they would find the problem.
He thinks they’ll end up just trying to sell him a new system.

100 detectors and 3 panels all connected wirelessly

What could go wrong

He thinks they’ll end up just trying to sell him a new system.

I think he's right - an upgrade has to happen sooner or later!

The EMS 5000 Wireless Fire Alarm System is Obsolete

Do you have an EMS 5000 fire alarm system? The wireless/radio alarm system was made obsolete in 2013 - here are the facts.

Unfortunately doesn't help you right now

Been back there today, and uncovered something. On any other panel, the fault just says “panel fault, net 03” but when I go to the actual panel number 3, the fault reads “fault RI”….. which according to the book is radio interference.
This system has been working for years without issue, fighting through thick brick walls over several hundred feet, and there’s been nothing introduced that could cause interference that I know of.

One question is whether it’s the radio link between the panels, or the system that communicates with each detector linked to that particular panel.

My next step is to disable every detector linked to that panel, until the fault clears or doesn’t.
I can speed that up by disabling zones of 4 or 5 detectors at a time.

Another question should be what can cause the interference? There’s been quite a few lamps replaced with LED recently… ??

Update:

After a few days of contacting EMS tech services, removing and re-enabling sensors, i got an email from them this morning saying there shouldn't be any reason that its not resetting.... perhaps you need to disconnect power, remove batterys to give it a full restart.... or alternatively press the 'warmstart' button inside the front cover...

The what now?

Had a look through all the documentation i could find, and indeed there is mention of this button.... but not where it is... just "press it if there's this problem"

Had a good look inside... and on the electronics board on the back of the panel... where the lcd screen is, there's a tiny button inside an access hole.... youde never see it if you werent looking for it....
Gave it a click, and the thing dies down... beeps loudly, then things start clicking back into place....

Total faults - none

Status - Normal



You beauty!



All i need to do now is source a couple of spare detector heads... they were giving faults too, and putting fresh battery's in didn't help.... Only stock available for redundant system is from Ebay... and sellers are looking for £180 plus......

You sleep tonight, f@@k hell that alarms going off, it's only my clock.

Theyve got at least 3 faulty detectors now.... new battery doesnt help.
The original detectors for this system is stupid money on ebay... but can get the newer version detectors, second hand, from a supposedly working system for about 25 each.

eventually... they are going to need a new system, and i cant see it being a straight swap of each panel and detector....
They would like me to do it though.... when the time comes....

So to design, install and commission a new system, what trade bodies would i need to become a member of?
Theres BAFE that i read.... anyone else? I dont mind doing a bit of training, and paying for a certificate, if it covers me to install this, plus get the service contract??

Manufacturers will often offer a design service, as long as you use their products.
