security lighting

[saleem]

hi.i have security light with pir sitting on out side wall very close to boiler flue.problem is smoke keeps triggering it on all the time.i have decided to replace it with separate pir further away from flue and leave light where it is at the presant.first of all i would like to know how to connect new pir to old light.could i use same light if existing pir is terminated or its worth buying new bulk head possibely new energy saving one.i need better quality pir,so any brand suggestion.thanks

Buy a low energy bulkhead and ditch the old light.

It will be easier than trying to wrestle with disabling the PIR in the old light.

Didn't your PIR come with a wiring diagram.??

Live and neutral to the PIR
Switched live and neutral from the PIR to the lamp. It cannot be easier, really.

Saleem, yes you can retain the existing light fitting and simply disable its sensor. Then you can wire from there to the new PIR position using 3 Core&E cable (or preferaby black-sheathed 4-core flex if clipped externally in full sun). This isn't such a difficult task.

Bear in mind that if you replace the fitting with an 'energy saving' bulkhead, that the remote sensor will have to be compatible with such lamps (some PIR's are not).

Moreover, there's little point to fitting a cfl lamp to a timed PIR, because it won't be on long enough to save energy and most of its time would be in the 'warming up' process to attain full brightness.

Any 'standalone' PIR will do you for this. Approximate cost £9 - £12.

It really isn't difficult to disable an inbuilt sensor and to replace it with a remote sensor.....

thanks.you have mentioned black-sheathed 4-core flex,is it a speical flex such as heat -resistent.
