Accenta G3 alarm panel

[nick higgins]

Hi. Although not showing any faults, I recently replaced the standby battery in my intruder alarm and noticed that some scorching has ocurred in one of the resistors. See photo. Is this repairable?
Is it symptomatic of other faults? Should I replace? For now, I have removed all fuses and disconnected the battery sobthe system is 'dead'.

I suspect it is a current limiting resistor for the charging circuit. In theory, it would be nice to replace it, but with what? (You would need to know the value of the resistor)
As the panel is over 20 years old I wouldn't worry about it, put the fuses back in, in the right order, put a new battery in (Write the date on it) switch the mains on and see what happens.

Can't remember any of these panels that didn't have some scorching which is usually down to the battery being well beyond it's use by date

Thank you for your response. I have rectores everything and system works fine. However, it is, as you point out , it is ,20 years+ old and is likely obsolete. My wife is insisting on a new alarm system (something like wireless Ring)!

As you (Your wife) wishes. I wouldn't. (Yes, it is obsolete, has been for many years)

I would change the panel and the detectors, maybe the external siren.
Ring is expensive compared to what you have, and they always have add ons that bump up the price and work best with a subscription. (more money)
Oh, and not to mention all the devices will need new batteries every few years, the cost of these will only go one way.

Wireless seems a daft idea when you already have wiring in place for a more reliable wired system..

And its easy enough to test all of the wiring to verify its still usable..

I would look at replacing it with a new hard-wired system.

wireless will get on your nerves with regular battery replacement.

reuse the exsiting cables to install updated system wth the functions you want.

As others have said you have all the wiring in place so why not utilise it. There are plenty of control panels available to directly replace what you have and at the same time it would be worth replacing the other system components to bring the whole system up to the current technology that is available

Wireless can have it's limitations and if the manufacturer decides to change the comms protocols to prevent security issues you could have an expensive wireless system that becomes obsolete because you can't extend it or replace any failed components
