Afternoon ,

Client would like 3 lights controlled from 2 pir detectors ,

so when 1 pir is activated all 3 lights come on + client would like a manual override switch .

Is there a cheapish way round this .

I would normally fit the GJD control box & run signel cables round to pirs etc.... to do this on this job would be well over the top

its a bungalow a small bungalow as well .

Please help

cheers

I'd just wire ordinary (mains, relay switched) PIRs in parallel - one length of 3-core+E looping around the lot - pick out SL + N at the lights, L+SL+N at the PIRs, override-on switch connects L+SL.

I'd go with Andy, just make sure the PIR's have relays not triacs as some don't like being paralleled.

you could use wireless sensors and switch, possibly more expensive on parts but less on labour.

Its not particularly difficult. Do as Andy suggests,

PIRs work Ok in parallel and the override switch is basically a single pole two way connecting the lights to the common, L1 connects the live feed looped to the PIR and L2 provides the switch line to the PIRs and onto the lights, the neutrals are there just to get into party......

I've never found pir's that don't work in parallel, even cheap ones. What triac ones don't like is switching 2d's, etc.

If you use cheap Chinese triad pir's connect via a contactor.
