Can I save on the cost to remove a security alarm by doing it myself? If you don't have prior experience, we'd recommend against removing a wired-in burglar alarm yourself. There's always a safety risk involved when you're working with electricity and electricians are highly skilled professionals.
The best thing to do would be to knock on their door when the alarm goes off. Either they'll come to the door or they'll turn the alarm off.
Alarm systems should have an automatic cut-off device fitted to stop the alarm sounding after 20 minutes. Most modern alarms have such a device already fitted, but cut-out devices can be fitted to older, existing systems.
Open the front of the alarm panel, it may be held in place by a couple of screws. Once inside locate the battery, the battery will have two connections, a red and a black, remove both of these connections.
Can I reuse old security system wiring? In a practical sense, a person can easily use the most modern security devices with their old coaxial wiring. Whereas the more aged the wiring is, the less capable it will be to produce quality, they are still usable when switching to the newest security DVR.
Low Battery Indicators. 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.
Unplug the power or turn it off at the fused spur. The panel battery will eventually die leaving the panel disabled. Alternatively turn off the power and remove the batteries in the panel by unscrewing the cover under the front flap, this way the panel is diabled straight away.
Most modern alarm systems are fitted with an automatic cut-off device that will stop the alarm from sounding after 15 minutes, so chances are that if you wait, the alarm will stop on its own.
Although the main source of power has been disconnected from the home security system, the backup battery is still providing power to the alarm. A screwdriver may be required to access the battery box and you will need pliers to remove the battery.
Wired alarms
Keep your alarm turned on so that if someone cuts the power, the backup battery kicks in. That may sound like a no-brainer, but you'd be surprised at how many people neglect to arm their security systems.
Remove Sensors and Detectors
Door and Window Sensors: Unscrew them and carefully pull them away from the door or window frame. Motion Detectors and Other Sensors: Disconnect the wiring.
Don your insulated rubber gloves and unscrew the faceplate from the control box. Remove the black and red wires feeding into the backup battery pack. If the alarm was sounding, it should stop once the battery pack is removed. Cap the wires for safety.
Unplug the alarm panel box's power supply and battery. You can usually find these in a utility closet, basement, or garage. Look for a metal box, usually gray. Once your box has powered down, plug back in.
There will be a red wire and a black wire clipped onto the battery, only one wire needs to be pulled off in order to completely disconnect the battery from the system. Once this is done and the transformer is unplugged, the system should be completely powered off.
Will the Police respond to any burglar or Personal attack alarm? No, only ones that are Installed, Maintained and Monitored by an Approved company such as those accredited by the NSI or the SSAIB (e.g. not Verisure, some ADT products etc).
If your alarm system is professionally monitored
Most systems will have a pre-programmed 'delay', usually around 1 minute or so, within which the alarm monitoring centre will wait until they call you or your chosen contact person/s.
Do Not Disturb, the Ring/Silent switch, and Silent mode don't affect the alarm sound. If you use the Ring/Silent switch or Action button to turn on Silent mode or turn on Do Not Disturb, the alarm still sounds.
