Hi, I’m adding a heat detector into my existing smoke detector system.
The new detector will be inspected and commissioned by an electrician, but I’m fitting it to the ceiling and running the cables to save time taken by a professional (their suggestion as they are very busy).
This is already a good loop of cable left in between detectors for exactly this eventuality - I just need to get the cable from under the loose Floorboards in a cupboard and across the joists to be further into the centre of the room. The joists in the trafficked part of the room can be drilled at centre so they are fine, but in the cupboard it becomes a problem due to 22mm f&r pipes and a gas supply. So my question is can these cables be let into shallow slots in the tops of the joists, on the basis that the boards are loose and will not be screwed or nailed?
I can’t see any other way of getting the cables past these obstacles.
Photo added for clarity.
Thanks.
