I have cancelled the monitoring of System by ADT/Broadview - Model BHS4000
And it starts to beep every 24 hours constantly. I can stop it by pressing cancel but it starts it again in the next 24 hours.

I tried looking to disconnect electrical, but it seems to be hard wired, no plug in.

Thx

Disconnect battery back up from service cabinet, and unplug the transformer.

Security & Fire Protection Systems: power down Brinks, key pads, co detector (http://en.allexperts.com/q/Security-Fire-Protection-2247/2012/7/power-brinks.htm)


You'll be able to power down your system without difficulty.

This is done in two steps, since the system is powered by both the battery that you found in the main cabinet, and by a transformer that's plugged into a wall outlet. All you need to do is unplug the transformer, and unplug the battery.

That's it. For good measure, you can unplug the telephone jack. This will prevent any possible issues if you decide to remove the control box.

You can now remove the keypads (they were powered from the control.

No its not hardwired but you must locate the control box, and the plug that's usually screwed into a wall socket. Check closets and hidden areas.
