I recently moved into a new home and it has a home alarm system installed. The system appears to be inactive, there's a keypad on the wall downstairs and a larger control unit upstairs - neither of them have lights on their display or make any sounds. There's also a number of motion sensors on various walls throughout the house (see example image) and an alarm siren on the front of the house.
The cabling to the motion sensors appear to be CAT 5 or 6.
I want to remove all these components as I'm investing in a wireless system, plus it will tidy the house a little!
I recently had an electrician upgrade my fuse box and I asked him to have a quick look, he confirmed that the power isn't coming from the fuse box, and that it's probably wired into one of the wall sockets? He looked at the upstairs control unit and could see mains power going to it, but he hadn't time to trace it's origin.
I have little or no knowledge of electric or power, bearing that in mind I have a few questions;
- can I safely remove all these components myself or should I pay a professional?
- can I simply cut / snip the leads connected to the motion sensors or is there a dangerous current?
Any advice appreciated.
