wiring to detectors

[Guest stejrobbo]

ive read in the forum that you should not run cables going to the detectors next to any lighting / socket cables because it could trigger a false alarm.......in this instance because the panel is in a porch the twin and earth run thro the wall threaded thro some piping it, would be dead easy to run all the wires for the detectors thro this pipe or should i put a smaller tube thro with all the detector wiring thro this to give it more insulation......hope you get it

NEVER RUN ALARM CABLES NEXT MAINS CABLES!

Mains Voltages will induce AC onto your alarm cables and cause false alarms.

In your case where you are contemplating running them together within a conduit, you are asking for big trouble.

There are plenty of posts here as you have discovered pointing out the problems, im surprised you think your alarm cables will be any different.

thanks for that.......but how far away is ok

Make sure your paying for decent PIR units is as important as the wiring runs.

PIRs at 8quid are asking for trouble...

I agree with Rich, price shouldn't be the only reason you choose a detector, there are lots of quality manufacturers who spend a lot of money on R&D and this knowledge is put into there products regardless of where the products stand in their range.

The more of something you buy the cheaper they become.

Price is a factor, but you have to take the manufacturers pedigree into account and more importantly the detectors suitabillity for the Job.
