Posted By: RexCan I replace a 6v with a 7.2V?

I don't know; that would depend on the exact design of your sounder. But why would you want to? There seem to be plenty of similar 6V batteries for sale. For example, https://www.buyabattery.co.uk/batteries-by-use/wireless-alarm-batteries/alarm-bell-box-batteries/alarm-bell-box-battery-6v-6-volt-ni-mh-gp320bvh5a6.html (you could ask them when it is coming back into stock or buy similar elsewhere)

What does the code tell me?

Again, I don't know exactly, but the 320 part seems to tell you the capacity in mAh. You don't need to match the capacity exactly, that will just affect how long it can run without external power. And your 280H5A1H code doesn't seem to exactly match a 330 mAh battery. So don't worry if the replacement is a bit bigger or a bit smaller.

"Very sorry, these are no longer available. i will have to get IT to remove the listing!!!"

Just like searching for anything on the internet, many listing at the top of the pile until you click the link to find no longer available.

I have fitted a new 6v NiMh sounder battery and replaced the panel 12v battery. Everything looks good until I reconnect the panel mains power when the sounder, rather than the alarm sound, emits a loud constant beep, beep, beep. It is not as ear-piercing as the alarm, but certainly annoyingly loud as if it is a warning signal.

I don't intend to fiddle with anything as the only things I have done is replace the respective batteries; no wiring has been altered whatsoever. Although the sounder battery is new, without mains power, presumably, it will not charge? But with mains, there is this beeping.

What is the next thing to look at?

Thanks

It is fifteen years ago that I installed the alarm and of course, don't recall what I did.

Fitted a new sounder battery (checked and is 6.3v) and followed the installation guide. When mains power is supplied to the panel, the mains light glows and the external sounder starts beeping. When the panel battery is connected, the sound makes a slightly different but still and alarm sound.

Can get the keypad into action with my user code but the sounder is still making this loud warning beep, beep, beep around two per second. It is not the normal alarm siren.

Having ensured all the tampers are depressed, I have tried resetting with my user code, the default code (0123) and engineer code, but nothing turns off the beeping.

Thought I would have solved it today but what's next?

The bell box is no longer in production and I would not bet on my chances of finding a ways to contact them.

As it happens having spent on a replacement battery which has not solved the issue, I have found on eBay, a new sounder for a relatively low price and am awaiting delivery.

If I knew anything about how to test circuits with multi-meter, I would do so, but that is a world beyond my knowledge.

As an aside, when I sign in and post a reply, I find that I am whispering to myself and it is not publicly visible. If on the other hand, I open the GBF page, write a reply and then Add to Comments, it appears.

What am I doing wrong?

To handle my sounder issue first; new one arrived and wired up. As an old unit, the 6v battery only measures 4.4v so installed the new battery. Wish I could report that all was well but no.

The same 'kinda' warning beep happens. Did some checking and found that the entire system appears to operate just fine when the mains is not connected; i.e it seems to be working on the batteries.

But connect the mains, the alarm operates, enter my code and the alarm stops but the loud warning beep continues from the sounder.

Put the original back and did the same tests with the same result. On the mains, a warning beep. Guess the sounder is not the issue but beats me what is happening on the main panel as I only replaced the 12v battery.

As for the whisper comments, if I just write in the comments section and Add, all is fine. But if I log-on at the top of the page, then add a comment, it is Whispered to me and not showing in the thread.

Yep; that worked, many thanks,

Now back to the sounder!

Have you tried linking out the tamper circuit in the main panel and checking that the tamper switch on the main panel cover is operating.

The frequency of beeping may well mean something that the panel manufacture would be able to explain to you so worth contacting them

In simple terms; bell box and panel batteries are both new, giving 6.2v and 12v respectively With the batteries connected (no mains) and the tamper held down, the system does what it is supposed to do. Any PIR activates the alarm and I can turn it off, no worries. All fuses are good and the battery is getting its correct mains voltage when the mains is on. All LED glow correctly.

BUT.....press in the mains fuse (mains fused supply to the immediate right of this photo) and although the system appears to be working, the sounder is making a loud warning beep beep beep. Resetting and the system appears to be working on the mains, but with this constant background sounder beep, beep, beep. Not the alarm siren, just an incessant beeping. Presumably, there is a mains fault.

Nothing is showing on the RKP as it is some kind of warning.

These ADE (Acenta Gen4 Mini and Reson 8 sounder) items are both now Honeywell and the call automatically cuts off having pressed the correct option.

I realise that it is not possible to suggest what is happening from looking at a poor quality photo, but perhaps someone would be kind enough to make a suggestion.

Many thanks

Yes, it is correctly connected. But this noise happened before I renewed the batteries when all had been working for a few years with no issues.

Although I fitted a replacement (new, unused but obviously old) bell box, and subsequently replaced the original, before removing, I took a photo of the connections to ensure that I connected correctly.

And it is working on the batteries, and the mains with this additional 'warning' beep from the sounder. Nothing from the RKP once reset and no message as to what is happening.

I do wonder if the sounder is telling me the battery needs charging but it is new and reading 6.2v

Thought I just posted a longish response but cannot see it; second time lucky!

Thanks for your thoughts and I do feel a bit guilty of this mountain out of a mole hill.

Not sure about a buzzer on the control panel but certainly on the RKP. Perhaps I'm guilty of not using the correct term but the two per second sound (loud beeping) is from the external bell box. This is not a smoke alarm, once every twenty seconds single quite beep to warn of a battery issue. It is an extremely loud, excessively aggressive (not as aggressive as the siren) 2 - 3 per second beeping. Much more that one would expect as a battery warning, and it is only happening when the mains is live. On the batteries, all is fine once the tamper lockout has been cleared.

Cannot imagine a tamper fault as it is not happening with the batteries.

Regarding Zone 8. never had a link installed as we only have seven PIR sensors around the house; nothing on windows or doors. No Fire or PA set; just plain vanilla seven zone PIR sensors; not connected to the phone.

An earlier suggest was to remove the bell box piezo buzzer from the equation but there is no piezo buzzer on the bell box board.

And the new bell box was doing the same so currently have the original installed since presumably, it is not faulty.

Just to reiterate, this noise started spontaneously when I set the alarm one morning. Have done nothing whatsoever to the alarm until this noise started. Didn't even check the batteries; it just started.

I have not dived into the panel config since it was installed 15 years ago but perhaps X days with no power and it has defaulted to its factory settings. But if it has done that, my user code still works.

Will have a look; thanks fro the suggestion.

Regarding a wiring fault on the panel, anything is a possibility, but since the beeping started a few weeks ago when I set the alarm to go out, there is no reason that the panel would develop a self-inflicted wiring fault? Or is there?

Checking the panel and manual, 7 & 8 are fire zones, but I do have 7 set as one of the PIR sensors. BUT, it has been that way for 15 years. so unlikely to be the cause.

I felt like it was using it to catch moths.
But it could just have gone faulty, I didn’t establish cause or effect.
Just turned it off at the switch indoors.

no spiders but this beeping from the bell box is not the same sound as the siren activation, it is a loud, incessant beeping, more like a very loud warning. But certainly not the sort of gentle flat battery warning.

And as there is not piezo buzzer on the bell box board, it can only be from the siren module itself.

I do have a second RKP and was checking if that is AOK with the messages but those are the same as the front door RKP.

My thoughts but i don't have a solution (yet?) It is all working on battery but this 'half' alarm happens when the mains is connected. Somehow, mains voltage that can only be 12/13v is triggering something and causing the bell box to make this beeping,

I am not fully familiar with how to use a multi-meter, but presumably, when the system is in set mode, there would be no signal (volts?) from the board to the bell box? If that is the case, given that there are only five wires to the bell box, how do I check?
