Im not familiar with ION so this is guesswork and what I can see on the pcb. Unless there is a global tamper I would say you need EOL on the circuits. LS would be loud speaker? The link going to TR would be tamper return I cant see the terminal marking where the link comes from but I would guess hold off pos and neg output 1 bell 2 strobe. Again all guesses, but Ive done this alarm installing sort of thing before a few times

Those look double pole to me but your thumb is over the terminals in the picture so cant be sure. It looks like it was terminated by a 5 year old though, you shouldnt be able to see any strands of wire like that.

If the panel is over 30 years old it will be using double pole tamper and alarm circuits rather than EOL so you can use any shock detector with separate tamper and intruder circuits

Hi and welcome the site is not as busy as it once was, but the ones that continue to visit are a good bunch old school

Obvs cant speak french then😂

Bonjour

Hi Jeremy and welcome

welcome to the forum please observe the rules before posting no links please

This will mean they cant sideload the Police response malarkey on their adverts

Your not allowed to talk about your employees like that anymore

Are you sure its the panel battery? Where did you purchase the replacement battery, if its been sitting on a shelf for years it will be as flat as the one you replaced it with. How old was the original battery? Anything over four years could have been slowly killing the charging circuit? It could be a resettable fuse on the CPU so as Happy says restart the panel and powering up mains first followed by battery, if that doesnt fix it check the charging circuit next.

Hi John

At home I have super fast up and download speeds, at work its abismal there is fibre in the street to the residents up the road, but they wont bring it onto our estate because there is a printer with a rented line and a stonemason with a rented line both paying £600ppm upwards (I could share but I dont want them on our network) We currently have a 3 mobile router for internet only but its no good for the 3cx because its not got a fixed IP. I may look at starlink if fibre doesnt happen soon

I think you are right, I vaguely remember seeing one in the 90's, I think it used DTMF to talk to the panel I doubt the 8136 is the same protocol

If it hasnt been serviced in a while its probably battery, replacing the battery may fix it. However, a good battery would have lasted 8 hours, so your battery is pretty poor, and if your battery has been that bad for a while it would have degraded the charging circuit, which means that the charging circuit wont charge your new battery.
