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)!

 

[Richard-the-Ninth]

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 I wouldn't. (Yes, it is obsolete, has been for many years)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

Thanks! Some really good advice! I've been looking at some of the available wireless systems online and agree that they can become expensive to match what I already have in place. Also, my wifi can be a bit temperamental at times and I certainly don't like the idea of battery powered everything! So, I think I will go for the hardwire upgrade you suggest. Thanks again.

Not least, if we DO get into power blackout situations most wi-fi systems will be dead. Your traditional system with its single battery will work as normal.

This is quite normal for most ADE (now Honeywell) panels. You might try using the resistor colour code if it's still legible if you want to replace it. If it's this item that causes the panel to fail, it may well be worth replacing it as it'll save the purchase of a new panel ( these are a not available now), I'm a believer of trying to keep things running at an economic cost. The nearest type of panel is Veritas 8 at approaching £100.

Thanks. Ive temporarily disabled the system and isolated power to enable me to take the panel out for closer inspection!

I don't know where you are finding or buying the Veritas 8 at approaching £100 when it's available around the £70 mark

If you look at the resistor in question, you can clearly see the colour code has been burnt off.

With most alarm panels, it is not worth trying to repair them, and as it is at least 20 years old, and no doubt the keypad will fail next and that too is obsolete.
