I wish to add a sensor to my existing intruder alarm system and would like the cabling to be as unobtrusive as possible. Is it acceptable to bring the cable through the ceiling behind coving and chase the alarm cable directly into the wall and then plaster over? Also, does the cable have to be clipped to joists in the ceiling void, or can it just lay on the plasterboard ceiling?
Thanks for any replies.
