Your alarm system is an important line of defense in keeping your Christchurch home safe. But here’s the thing that a surprising number of people overlook: alarm system batteries don’t last forever. We have been helping keep local homeowners safe since 1981 and one of the most frequent issues we encounter? Batteries either dying or outright forgotten until the system starts beeping or drops off.
If you’re hearing funny noises, having to look at warning lights, or you don’t remember when you most recently heard your alarm chime, then it’s probably safe to say you need a new one. Let’s run through all you need to know about home alarm battery replacement in Christchurch, so you can continue that protection around the clock.
The majority of home alarm systems in Christchurch are mains powered, however they all have a backup battery to keep them running in the event of power loss, storms or accidental cuts. If your battery is not functioning, your alarm system is able to:
✔ Emergency Cut off when Power Failure
✔ Not notify you (or monitoring) during a burglary
Nuisance Alarms– Offering trouble after the tension die down Low battery alarm– Impacting on the low battery signal KEEP Making NOISE Until You change it Annoying!
✔ Impact your insurance if it isn’t well maintained
This is why swapping out the power source of your alarm system is as crucial as securing your doors at night.
A question we hear all the time:
Your security system is most likely powered by 12v sealed lead acid battery (SLA) in the majority of recent Christchurch homes. These are commonly sited within the control panel or principle alarm box. They’re reliable, and they are designed to keep the system running if power is lost.
We regularly replace and install the following types of products at Action Security:
✔ Compatible with 12v 7Ah or 12v 9Ah sealed lead acid batteries
✔ Batteries compatible with multiple brands of sensors such as DSC, Paradox, Micron, Arrowhead and more
✔ Long-life for homes prone to outages or rural homes
You want to make sure you’re using the right battery for your system, so that it works properly without sowing the seeds for damage.
All is not lost — technically, anyway — though you may not want to go that route the majority of the time we don’t advise it, anyway.
Many homeowners ask:
Changing an Alarm Battery on Your Own Replacing an alarm battery yourself is amenable and there are a couple of suggestions for doing so:
Safety First - Any time you tinker with an electrical system, especially one you're not familiar with, it's important to take caution.
Alarm Settings - Some systems may need to be reprogrammed or reset after battery replacement.
False Alarm – The incorrect operation will cause your machine to blare or false alarm.
Warranty will be Voided – Doing it yourself will void all warranties and service agreements.
Do not attempt to service it yourself unless you’re familiar with the internal operation of your alarm system – if you’re not sure, please contact a trained technician from Action Security. We have it under control and we make our decisions quickly, safely, and without making your day in the least bit and without inconvenience to you.
Excellent question – and the answer might be different.
If your alarm’s battery dies, one of the following scenarios could play out:
The worst that can happen:
You’re at risk of losing power entirely in your system during a power cut.
Features such as remote access or notifications may not work
You may receive false alarms or loud beep every minute or two.
How much more exposed your property will be in the event of an actual intrusion
In practical terms, if the battery dies, your whole home security architecture cannot be counted on — and usually at the most inopportune time. If you don’t know how old your battery is, or what condition it’s in, it’s always best to replace it before it dies.
That irritating beeping is more than just an annoyance — it’s your alarm system attempting to tell you that something isn’t right.
The most frequent cause of an alarm beeping is a power loss or battery problem. To stop the beeping:
Resist the urge to just pull out the battery — it won’t get to the root of the problem, and it might even render your alarm system inoperable.
How Often to Replace an Alarm System Battery Most alarm system batteries should be replaced every 3 to 5 years, but there are some exceptions.
We advise clients to test their alarm systems as part of the regular home maintenance, at least once a year. If caught in time, a knowledgeable technician can identify early warning signs of battery failure and keep your alarm system ready to help protect.
