If your power goes out, your system will run on its back-up battery for approximately 4-6 hours. When the power returns, your panel battery should recharge within 24-48 hours.
Alarm batteries in the panel act as a vital backup in case there is loss of mains power. If fully charged and in working order, a panel battery can keep your alarm working for upto 12 hours without mains power. Batteries in wireless sensors are their only source of power.
When there is a power outage, the alarms begin using the backup battery instead of the building power supply. In some case, the alarm will then chirp to indicate that there is a power failure. Since the detector is still receiving power from the battery, the detector can still activate and go off.
The ADT Smart Home Hub and ADT Base include a backup battery that last 24 hours. Communications to the ADT Monitoring Centers may still be disrupted in the event of a power outage if your router and internet communications do not also have battery backup.
An ADT Alarm System's low battery beeping can be silenced by pressing the ``OFF'' button or ``#'' button on your keypad.
If you lose power, your ADT monitored security system will not turn off and leave you vulnerable to a break-in or fire. Your alarm system has a backup battery to prevent it from turning off.
When you order on MyADT, your QSP provides one free system battery per year. Additional system batteries cost $29.99.
98% of the time an alarm rings during a power cut is because this battery is dead! Therefore when the mains is removed, the main control panel battery can't keep the system running so the external sounder starts ringing to inform you there's a problem.
If so, the device will run on its backup battery for up to 24 hours, and you will get a low battery alert as it is depleted. If AC power is not restored before the battery dies, the device will power down.
Most Alarm Systems Have Backup Batteries — But There's a Catch. These days, many traditional home security systems run on power from your home. If that power suddenly becomes unavailable, many systems provide backup batteries to keep the keypad and alarm operational.
For this reason, all modern alarm systems have a battery backup designed to power the system for 10-24 hours, depending on the complexity of the system and the condition of the battery.
Even if the battery goes dead, the system should continue to work from the wall power. When the panel battery begins to get weak, your system will alert you to the problem.
The alarm in your home security system is designed to be a deterrent to intruders, as well as alert occupants and draw attention to your home, whether that be from neighbours, passers-by or authorities. Systems will sound for about 5 to 10 minutes, depending on the system, before stopping and automatically re-arming.
All good alarm systems have back-up battery power. It ensures they remain for at least 12 hours in the event of a power outage (power cut). When power is restored following an outage, the system is designed to start working normally and also recharge the battery. All batteries have limited life.
Go to your main control box and disconnect the battery supply, which will stop all beeping and shut your alarm system down. Once power is restored, you can reconnect your battery and your alarm system should work as before.
Most manufacturers recommend changing your system's battery every 3–5 years. Newer devices may last up to 7 years. If you don't know when your system was last serviced, start looking for a replacement battery now.
Power Outages or Fluctuations: After a power outage, your security system might beep to indicate a reset. Solution: Check the system's battery backup or consult the user manual for reset instructions. Low Battery Warning: Most security systems have a battery backup.
If I lose power, will my alarm system still work? Yes. In a power loss, the back-up battery will activate and will operate your alarm system for several hours. In the event your system battery is or becomes low, a low-battery signal will be sent to ADT's Customer Monitoring Center.
Requesting a Replacement Battery
If you choose to replace the battery yourself, contact ADT at 1-800-ADT-ASAP to have a replacement battery sent to you or you can purchase one at a local battery supply store.
Most systems will begin beeping or chirping as a result of a total power outage or failure to recharge the system backup battery. For many of our most popular systems, beeping alarms and low battery trouble beeps can be silenced by pressing the [OFF] or [#] buttons from the keypad.
In the event of a power outage, perhaps because of adverse weather or a problem at the power station, the reserve battery is there to keep the system fully operational whilst the mains power is off. It is almost always the case that if the alarm goes off when not required, it is due to a failing internal battery.
A low battery warning is most often displayed as BAT, LOW BATT or SYSTEM LO BAT on the touchpad. This warning signals that your battery is low and must be either recharged or replaced. ADT offers several battery-replacement options for our customers, including a self-service option on most systems and devices.
