The company could still be monitoring the alarm. Cutting or disconnecting wires can alert the provider of a potential security breach, so a warning will let them know no foul play is happening.
Most security and alarm cables are typically rated to very low voltage (12V, 120V, 300V or some other low voltage) because many of them do not supply power.
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.
My advice & suggestion: Leave the old wiring. Patch holes as needed and where needed. Remove and keep all the components. Next owner may or may not want them. Or simply toss them into recycle trash. Most likely very outdated and obsolete components anyway. Wireless is and has been the trend for many years now.
Contact Your Alarm Company
Most monitoring services will automatically dispatch the police if a wire is cut or if the system loses power. This is why you should always call your provider before making any changes to your system.
Remove the AC power to the home alarm console from the wall directly. Use your console's access key (or another item such as a small screw) to unlock and open the system's backing. Lastly, disconnect at least one of the wires that are attached to the system's main battery, which is blocky and noticeable in most units.
Removing your old wired system
Some companies, like ADT and Vivint, will help you through the entire removal process (with an option to upgrade), but it's not common and it doesn't help if you're switching to a new system from a different company.
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.
Use a pair of pliers to remove the appropriate fuse. That should take care of the alarm in all cases except one (noted below) since the alarm won't run without electricity.
Your home security system likely has a main source of power, which is a box that is secured to the wall with an outlet. This box is the key to turning off the alarm while there is no electricity. Simply disconnect the box from the outlet by unplugging it.
I believe that standard six core alarm cable is red, black, blue, yellow, green, white but you can get more cores and obviously it changes accordingly.
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.
Open your device's Clock app . Tap Alarm. On the alarm you want, tap the Down arrow . Cancel: Turn the switch on or off.
Alarm System How to Terminate a Contract
It is within your rights to terminate the contract at any time. To do so, you must simply advise the service provider verbally or in writing, preferably by registered mail.
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.
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.
Home insurance providers typically offer insurance discounts for alarm systems that can range from 2-10%, largely depending on what kinds of security and safety devices and systems you install. More preventive measures usually add up to bigger discounts. You shouldn't install these items just for the discount, however.
At the termination of your contract, ADT has the right to remove, disable or abandon any of the equipment they own. Typically, they'll simply leave the equipment on the house, and you (or a new owner, if you sell) can re-activate service at any time.
