House alarm goes off when power comes back on
HTML-код
- Опубликовано: 9 сен 2024
- house alarm goes off when power comes back on is a very common problem with many house alarms and in most cases it means that the alarm’s internal battery is flat or no longer working. Rectifying a house alarm sound when power cut is very easy and normally be fixed by installing a new battery, which should cost less than £15 and can be changed in a matter of minutes. The burglar alarm in this video is a ADE Accenta which is very similar to the ADE Optima alarm, changing the battery on these alarms is normally very easy.
Straight, down to earth & effective. Top guy!
Thanks for the comment 👍
Good clear instructions. A very helpful exercise. Thank you.
I'm glad the video helped
Thanks for the comment 👍
I suspect this will be a popular video! Some good advice for sure. A lot of people don't realise until there is a power cut and their alarm starts sounding uncontrollably! It's worth regularly changing the backup battery every 3 years (more often if the panel is in an area with a high ambient temperature like an airing cupboard) as a precaution. Definitely one of the most common callouts we get to unmaintained systems. It's also worth disconnecting the mains for a short while after replacing the battery to check it does actually takeover in the event of a power cut.
Thanks Scott, I thought this battery would have lasted longer than it did, as I replaced the main house alarm battery 2 years before I installed the alarm in this video and the battery is still fine in that!
I did get them at different places though, the battery in this alarm was from CPC online (2.2AH) and the battery in the house was bought from my local electrical shop (2.1AH).
I'll remove the fuse that feeds mine later today to check that it takes over ;-)
Thanks for the comment.
We had a power cut and my neighbours Alarm went off and my Alarm did not go off or if it did, I must be fast in a Deep sleep. My neighbours saying first we could hear Alarm and we could not switch the Alarm , keys on the keypad would not response. Neighbour rang me in the morning and was asking did you Alarm go off and I said not I am aware off, but as I was leaving for work I saw tamper light on. So the neighbour think it must my Alarm going off and not there’s. I also have the Auto Dialler speech, which calls me on my mobile and I did not get a phone call, I rang Texecom and told me you need to service your Alarm system, usually changing the battery, it needs to around 13volt to 14volt.
The below I wrote to technical team.
Hi TECH Support ,
Last week on Wednesday night, we had the Electric gone from the Main Grid, I don’t know how long, but my neighbour Alarm went off and all electricity went off for few minutes , as they messaged me and I said my Alarm did not go off nor my Electricity.
However when I woke up I never noticed this, but when my wife into the kitchen the microwave and the Cooker timing clock was showing wrong time, it was showing 05:05am and it was around 09:30am on my mobile at the time she mentioned, so the electricity must of gone in my house as well.
Next door neighbour was saying I am sure your alarm went off, but I said to her I did not hear the Alarm, but when I check the keypad it had Tamper light flashing on the remote keypad, so I reset it by pressing 12345 Eng code and reset.
My main question, if the Alarm did go off, I never got a phone call on my Mobile and this is bit strange.
When I fitted the Speech dialler I tested and it was all working fine for Dial and text, as I received the phone call and text and also the next caller as well.
I am bit confused where my neighbour was saying I am sure your alarm was going off and I did not hear it or the electricity may have gone for a while and the tamper light came on, but may have not triggered the Alarm.
I am dropping you guys email to see what are your thoughts.
It is possible the outside sounder activated only, as the internal sounder would have required voltage to be on the control panel to activate it. When the power was restored, the tamper indication may be from the mains fail and no sounder may be from the battery not having been serviced or replaced recently.
To assist, we suggest having the alarm serviced and the control panel battery checked and most likely replaced. For future reference, an alarm system should be serviced annually.
A meter would normally be required to check the battery on load and it would be the current that is checked and not the voltage.
A quick test would be to switch off the mains connection to the alarm panel and if the outside sounder sounds after a few moments, the control panel would require replacing, like for like.
It is usually the battery needs changing after every 3 years or you start to see a sign , where sometimes it does not accept keypad response.
You got me into alarms when i first watched all your “how to install” videos of you actually installing this system from scratch. Nice to see it is still in use and working.
Thanks for the comment 👍
found this video very informative.
Thanks for the comment
thanks i showed this to my parents because there was a power outage last night and our house alarm and many other house alarms in our area went off, we got a new battery from adt which is our security system
You are welcome. It's a very common problem!
Thanks for the comment 👍
Also write the date of install in marker pen on the new battery for the next owners of the house
Thanks for the comment
I am sure that your fingers were not near the transformer but in the video it looks as if you are very close. This is a good job to know how to do as the alarm people will charge an arm & a leg to do this for you.
You can touch the transformer as long as you don't go anywhere near the terminals, even then you should not be able to make contact with anything that is live- but best to warn people.
Thanks for the comment John ;-)
Great video looks like summer is starting over there it's getting cold here in Melbourne now.
Thanks, yes summer is going to get here eventually. It was very cold last weekend though, I need some warm days as it's difficult making videos in the garage when it is cold.
Thanks for the comment
Great vid ...but its very confusing how to change the alarm code!...Also our external box is making a throttled duck noise is this telling me I need to change the external battery? OR the under the stairs battery inside the panel OR both??
Great video. My battery is flat so need to replace it. But if i do it without the engineers number will the alarm definitely silence after i put the code in?
Thank you for a very informative video. My Optima XM alarm system was installed by so-called professionals more than 20 years ago, who, for some reason known only to themselves, decided to wire my alarm up to the light in the hall. Now, here's the thing, my alarm goes off whenever there's a power cut and this has been the case from day one. I just presumed this was the anti-tamper device kicking in after an interruption to the power supply. Unfortunately, it's a bit late for me to contact the company that installed my alarm, they ceased trading about ten years ago. I'm also thinking that if I replace the battery it'll just continue doing what it's always been doing. Any advice on this would be greatly appreciated.
If it's been doing that since day one they have either not installed a battery or forgotten to connect it.
Fitting a battery as per this video, should mean that the next time there is a power cut your alarm will not sound ;-)
@@ultimatehandyman Thanks for getting back to me so quickly, I never even considered that there might not be a back-up battery installed/connected, but that would make sense. Either way, given the fact that it's been 20+ years since the alarm system was installed, I'd probably be best to buy a new battery anyway. I'll let you know how things go. Thanks again for all your help.
UPDATE:- I successfully managed to replace my PIR sensors thanks to the guidance of your helpful videos. Replacing the battery, however, is proving to be a different matter... Remember how you thought maybe the installers either hadn't connected it correctly or hadn't installed one at all. Well I finally opened up the control panel for the very first time since having the system installed and found it does have a battery installed, which visually seems to be installed correctly, but the contact points are very badly corroded, so much so that I know if I try to remove the spade connectors they'll just fall apart. Presumably the battery was working ok when it was first installed, which still doesn't explain why the alarm goes off every time the power is switched back on after a power cut. By the way, I've bought a new battery, but I think I also need to replace the red and black battery wires. Any advice on where I may be able to obtain these? I've tried looking on eBay, but it would help if I knew what I was looking for, such as the size/gauge of the wire. Alternatively, would it be ok for me to just snip off the corroded ends of the wires (after completely removing them, of course) and replace the spade connectors?
@@bravejordy I have same system, I replaced battery but still alarming after power cut when the power is restored. Tried another battery but that's the same. Next I need to check current/voltage to the battery in case its a faulty wire. You should be okay snipping of spades and either fitting new ones or clean old with soft wire brush or emery paper and apply a smear of vaseline. The wires used are 5 amp and you can usually purchase in a hardware store.
Last week there was a power cut and my alarm was sounding when the power was restored. Lots of other burglar alarms were sounding in the area, this normally means the backup battery is flat or not holding charge long enough. Luckily it is an easy fix and normally inexpensive.
Today is a beautiful day here, time to go and film some more videos ;-)
I hope everyone has a great day!
Ultimate Handyman thank you for the video it helped on servicing my alarm myself rather than calling an engineer out.
You are welcome ;-)
I take it the system should recharge the battery when it is needed, but I do find it odd that the UK has not implemented some kind of nanny state law which says only licensed tradesmen are allowed to do this.
Yes, the transformer is supposed to charge the battery, but the battery stops holding charge after a few years.
I'm sure that the UK will implement laws that will prevent anyone from doing any type of DIY in future.
Thanks for the comment
Ultimate Handyman could you do a video on how to replace the battery in a external sounder please bud?
Storm Eunice brought me three power outages last night. I don't use my alarm and never give it a thought, although there was no doubt as to the origin of the noise. I'm happy to have found this video and can confidently swap out the battery now. That's unless you can tell me if there is a way of disabling it completely? I'm moving house soon and shutting it down is an option. Thank you! By the way, I have an ADE Accenta.
You can disable it completely by removing the fuse going to the alarm. There should be a FCU (fused connection unit), this will have a fuse that you can remove. If you remove the fuse, after the battery has lost it's charge completely, the alarm will no longer work. (you might have a battery in the external sounder, that might sound until the battery in that is depleted, normally about 20 minutes)
@@ultimatehandyman Thank you very much for taking the time to reply with a solution, along with the useful info on the external sounder. I'll be sure to try this during the daytime. Thanks again!
That will definitely wake you up when the power comes back on it’s nice and quiet to sleep with the power out
Absolutely.
Thanks for the comment
Top job 👍👍👍
Thanks for the comment ;-)
Great vid as always...I too have an alarm with most probably a duff battery (hasn't been changed in over 10 yrs) but my alarm goes off every time I switch the mains OFF to do some electrical work in my house and the siren only stops when I switch the mains back ON. Any ideas what might be causing this as its a right pain !
It sounds like your external siren has a back up battery, these are designed to sound when the power is cut completely (hold off circuit), which is why it goes off when the power is cut completely. If you replace the back up battery in the alarm panel- like in this video, you will be able to switch the electric off and the back up battery will ensure the hold off circuit works.
Thanks for the comment
Thanks for the info, much appreciated !
Can you leave in engineering mode permanently to stop alarm activation? Looking to get disconnected but want to stop alarm sounding in the meantime? TIA
Pet hate of mine is people who don't maintain their intruder alarms
Thanks for the comment
Thanks for the video! I replaced the battery and that worked great, but now the alarm does not sound when triggered in part-set mode at night. Any ideas? Thanks in advance
Does the strobe light flash outside when the alarm is triggered?
@@ultimatehandyman No it doesn't flash when triggered. The green unlocked padlock light also doesn't not go out either to indicate the alarm is set when put in part-set mode. thanks
I thought the battery should swith over when the power was lost. Then back to mains when the power is restored. So if the battery is flat surely the alarm would sound when the power is cut. The thing is with very short power outages, it sets burglar alarms off, the time on clocks on cookers are not lost( they have no battery back up). but if I switch the power off to the burglar alarm, it flicks to battery , and back OK. Its something about power outages?
The battery in the panel will enable the alarm to work during a power cut, however, if that battery is no longer working the alarm will not work until the mains power is restored. Hence with many alarms, the alarm will sound when the mains power is restored.
Some systems also have a SCB (self-contained battery) in the alarm bell box (situated outside). In the event of a power cut, and if the main battery is not working, the SCB will sound the external sounder until either that battery is exhausted, or the power is restored 👍
Hi. I Haven't had a power cut but the external sounder has been intermittently going off for days when not set. The internal sounders do not go off. No fault was indicated on LCD panel and inputting code to reset the alarm system does not solve it. I removed the main panel battery (without engineers code so internal alarms sounded) and the external continued for a minute then became very quiet and continued to sound quietly for 15 mins until I removed the battery from it. Would this be the battery in the panel or external sounder that needs replacing? Challenger system. Thanks - love all your DIY videos
Probably the external sounder needs replacing.
They get a lot of stick outside with the weather and often need replacing after 10 years or so.
Thanks for the comment 👍
I have recently moved to a new house with the accenta g3 and it's got a one keypad in the hallway which you use to enter the code when entering and exiting the house. but inside my cupboard I've got the main box and on top of that I've got another keypad which is connected to the main panel box so do you know what keypad that is ?
It sounds like it's another keypad. The older Accenta panels had a built in keypad, so you could operate the alarm from the main panel, or the remote keypad. Sometimes people put a remote near the alarm panel for ease of use. I have 2 keypads for my garage alarm, one in the garage and one in my office- ruclips.net/video/MU_n38qrJlg/видео.html
Thanks for the comment 👍
It also could be a speech dialler or auto dialler that calls the police/a phone number when the alarm goes off
You should also change the battery in the external bellbox if you can reach it, round about the same time as changing the battery in the main control panel, roughly every 3 to 5 years max, most bellboxes will still work even if their batteries are flat as most are set to sab, however if the intruder smashes up the main panel the bellbox will not sound as its battery is dead and then your system is defeated, on bellboxes set to scb (rare) you will know the battery is flat because it will be very quiet or may not sound at all on a bell test.
Word of warning tho, most bellboxes have an xenon strobe circuit which is high voltage and can give you quite a nasty belt(speaking from personal experience, it is quite a strong shock!) it may activate when you remove the bell cover due to the tamper, take care not to accidentally touch it,could be nasty if you are high up on a ladder, Also wear ear defenders.
Thanks for the tip, I was going to cover this in a future video. I always wear hearing protection when doing anything with my alarm as it is connected to a 120DB master blaster.
Thanks for the comment
Not a problem, you might also be aware that if you remove the cover from the sounder it will still sound even if the panel is in engineer, hearing protection is a must as its pretty loud when you are right next to the bloody thing lol :~)
stay safe
Thanks, it's about 15 years since I replaced a battery in a external sounder, so that would have caught me out for sure!
Thanks for reminding me ;-)
Can you leave the battery out for a few hours while you go and get a replacement?
Sure, no problem
Thanks for the comment 👍
I recently just replaced my battery purchased from amazon UK. It seems it may be faulty based upon this video which states on power coming on if alarm sounds battery is more than likely defective, or can something else cause this issue?
It’s unusual to get a faulty battery of this type from new, but always a possibility. Might be worth seeing if you can charge the battery using a bench power supply or similar. I'd also check any fuses in the alarm panel
Brilliant video, didn't even know there was a code to put it into engineering, I managed to access both the key pad & the box by following your advise, I've not yet replaced the battery, my alarm was just randomly going of without even being set, so not sure what's causing this, it was fitted in 2017, i moved here last yr, it's always been ok, until today, am a woman, so I'm kinda stuck as to y this is happening, & how would 1 know the battery needing changing, any ideas any 1 pls ?
When the alarm goes off, do any zone's illuminate, or perhaps the tamper light?
@@ultimatehandyman to be honest with u I left it on engineering mode as it just kept going of that i couldn't understand y, so rather than make a nuisance of myself, with the neighbours, over night, once i learnt from u the engineering route I was so relieved, have taken it back out ( of engineering mode ) now, & let u know once i have discovered that, it hasn't happened again yet, will check it out & let u know once it does, & a big thank u for coming back so fast i so appreciate this,
@@ultimatehandyman whilst I'm waiting for that 2 occur could i possibly ask have u a guidance vid on how to change the code on this system, I've had the same code the previous owners had in place, really could do with it changing it, hope u can help, many thanks 🤗
I have changed the battery but its still doing this. Even changed the fuse.
Are any tamper lights illuminated?
Good video it should (😵) help a lot of people who's alarm seem to go on for ever. 👍👍👍👍👍👍
Thanks, yes I don't think people realise how bad it is when their alarm goes off for no reason, especially as any burglars casing the joint will know that their back up battery is not working!
Thanks for the comment
Hi, where can I buy these batteries from? I can't even find them online. Thanks
You can get them on ebay- fave.co/2kjkMLH
Thanks for the comment
If you're installing or maintaining any security system, please make sure you don't leave any codes at their default. You're making it fat too easy for the burglar!
The engineers code can only be used when the alarm is unset.
Thanks for the comment
a lot of the replacement batteries arrive 70-90% charged.I have no way of charging lead acid batteries.Does the accenta panel top up the charge to 100% once inserted?
Yes the battery is constantly charged via the panel.
Thanks for the comment 👍
Hi My burglar alarm goes off for no reason after a few minutes it’s been switched on. I was wondering if you might know some possible way to fix this problem. Thanks
No idea, sorry.
Is there no indication of why the alarm goes off, such as tamper or a particular zone being indicated?
Can you do a dtv arial installation video please... Many thanks. :)
Sorry, I don't normally touch aerials as a local guy installs them cheaper than I can buy the bits for.
Thanks for the comment
Ultimate Handyman
Hate it when that happens... They may be cheaper but they are rookies and potentially would not do half a good job as a professional like yourself would :)
If I put it in engineer mode until I can replace the battery, will it stop the alarm going if we have a power cut? It’s gone off twice now but I can’t get a battery just yet and I’m trying to prevent it from happening again. I’m not bothered that it won’t work at all since we’ll be in and don’t need it to be working just yet. TIA
Not sure, but would assume that it will still alarm when the power comes back on.
hey bud - is it possible to check my alarm battery with a multi-meter to see if it is holding charge???
if so, do u know how to do it???
many thanks.
Voltage does not give much indication of how much capacity a battery has left, I have known batteries to read 12-13v but have no capacity left and struggle to supply the smallest of loads. Best way to check if your alarm battery is healthy is to switch off the mains, if the bellbox outside sounds and you can't stop it because the keypad has lost power, the battery in panel is knackered and needs replaced, if it doesn't sound and the system still has power then all is well. As rule of thumb your alarm battery should be replaced every 3 to 5 years, If you are unsure how old your alarm battery is then just replace it like for like, An alarm battery is only about £15, it will do no harm. Don't be like most of the fools out there who's alarms go off uncontrollably in a power cut because they couldn't be bothered to maintain their alarm.
The way I indicate a battery that’s out of date is leave it in the panel for a few hours then take it out and check with a multi meter and if the voltage drops quite quickly then the battery is obviously not working as it should. Hope that’s helpful!
My power just tripped the alarm panel keyboard light is on but the red and green power lights are not, when I press the keys there is nothing
It could be a few things depending on the make and model of the alarm.
Are you sure that the mains power has been restored?
If it has, try pressing the reset button a few times. If that does not work try inputting your code number.
If nothing at all is working, then perhaps a fuse has blown? 👍
The switch in my consumer unit that my alarm is on tripped on Saturday night. Inputing my code on the keypad would not turn the alarm off, so I had to at the fuse, remove the front panel, and remove the battery as it was waking the street up! Whilst in this condition there is no power to the keypad. When I restore power to the alarm, it immediately sounds. Can you tell me how to return my alarm to normal operation? I have the instructions and I think the engineer code is still default.
It sounds like you need a new battery.
Once you replace it, you should be able to silence the alarm by inputting your 4 digit code, you might need to press the reset button X
The alarm will stay in tamper mode until you close the cover, once the cover is closed, you should be able to press reset, sometimes twice X X
Then the alarm should be back to normal
@@ultimatehandyman ok, thanks for reply. The battery works because as soon as reconnect it, the alarms sounds outside again.
@@ultimatehandyman Hello again, I was able to reset using my code as you advised. It was all a bit of a panic on Saturday night when it was waking the whole street up.
I have a new problem now. The alarm will not set ! Instead of the slow timed beeps, I get shorter, quicker beeps and the alarm does not set. Any idea?
Thanks in advance.
@@davidboardman1566 Not sure, normally if there is a problem with the alarm there will be a visual indication (such as an illuminated LED)
some council houses dont even have an alarm maybe cos they have security doors
I don't have any alarm system in my home, it's not a council house. I live in the countryside and nobody ever really goes up here to what's the point.
Had a power cut last night alarm been going off problem I have we can’t find the code how do I turn the alarm off without the code
I'm afraid you need the code, If you don't know the code you can remove the internal battery and switch off the power to the alarm, although the external sounder might sound until the internal battery in the bell box is flat. If you find the manual online, it should tell you how to reset the alarm to it's default status.
Thanks for the comment 👍
I’m 10 in 55 days and I’m getting a pyronix alarm system wired you will like the system is sound good
👍
Hi bud my house alarm keeps going off I have changed the battery and put a new one
In but it keeps off during the night when we are asleep all doors are locked so can you help with this please
It could be several things causing it. The best option is to check the panel, it should tell you which zone is causing the alarm to trip. If it is the same zone each time, you have a problem with the sensor or the wiring on that zone. You can link omit the zone on the panel when setting the alarm, this should stop it from waking you at night. If this work it is worth checking the sensor, and perhaps replace it, then you don't need to omit it each time you set the alarm.
Ultimate Handyman ok thanks for the help 🍻🍻
My old alarm system had rechargeable batteries on a circuit board in the sounder boxes also.
Yes, most modern bell boxes have a self contained battery and hold off circuit (in case the power is cut completely, or the cable is cut going to the bell box)

Not sure what the problem is.
I would start by checking any fuses in the main panel.
Mines out of battery and the external sounder goes off during a power cut
It will do. The bell box has a external battery and hold off circuit. When the power is cut to the bell box it will alarm until power is restored. Replacing the battery in the alarm panel will fix it ;-)
@@ultimatehandyman that's what I thought, though the alarm stops after about 20 minutes
@@yeety1208 The battery in the external sounder will probably have run flat after 20 minutes, that's why it stops.
I think they design the battery in the external sounder to last for 20 minutes then it does not create a noise nuisance, if you can't silence it.
What if you need a 2.1ah but got a 2.3ah
It will be fine, as long as it fits in the panel. The larger the AH, the longer the charge will last.
