Security During a Power Cut
Whether it’s after a storm, during maintenance work or simply after something’s gone wrong at the power station, power cuts are inconvenient at the best of times. The lights are off, the Wi-Fi is down – and to top it off, your security alarm has started to beep.
If you’ve experienced – or are experiencing – a power cut, you might be left wondering what to do with your security system, and whether or not your home or business will remain secure while the power is down. This short guide covers the basics, but our team is always on hand for further assistance.
Does the system still work during a power cut?
Most common alarm systems, including ADT models, feature built-in backup batteries, specifically to keep your security system up and running in the event of a power cut. You won’t have to do anything for your alarm to start using power from the backup battery, it will switch to batteries automatically when mains power is out.
Why does my alarm sound during a power cut?
The most common reason alarms sound when power drops is due to a faulty or not charged back up battery. This could result in the siren activating or sounding during a power failure. Depending on your alarm, you may be able to replace this yourself, or you may have to contact the manufacturer to do it for you and disarm the alert with a code – always consult the manufacturer’s manual first.
The alarm system will give indication of a mains power failure by bleeping shortly after the mains outage occurs. You should be able to shut off the noise with a code or another instruction. With an ADT alarm, the beeping will sound from the control system, and you can simply enter your keypad code to dismiss the alert.
More advanced alarms, such as ADT systems, are able to charge their own backup batteries through the mains power when restored. However, if issues persist, we’ll check for faults through our remote service, and will service your alarm system at a time that suits you. All ADT alarms are monitored and come with an all-inclusive package as standard, meaning components such as batteries will be replaced free of charge.
How do I reset my alarm after a power cut?
You shouldn’t need to reset your alarm after a power cut. After you’ve dismissed any alerts and ensured the backup battery is working correctly, your alarm should continue working as normal.
If you have any other issues with your alarm, consult your manual or contact the manufacturer for further advice. With older alarms, you may simply be able to cut off mains power and remove the backup battery to shut the system down completely in the meantime.
ADT customers have access to 24/7/365 all-inclusive support as standard, meaning we’re always on hand to help. Oftentimes, our Remote Operating Centre can solve system issues without even visiting your property. Of course, if we do need to physically service your alarm, we’ll get someone out to you as soon as we can.
