Completely depends on the job.

Depends on the light and what terminals you ca get at, some are sealed so you can;t get to the switched terminal for override. Where you can get to the switched terminal just wire the override between live and switched live or provide perm live and switched live to the relevant terminals.

 
8 pound from b&q for a complete unit.

stand alone pir are triple that then you still have to buy the lamp .... :)

 
I fitted a Micromark PIR light, and the overide worked by quickly switchin off and the on again the light. I think within 2 secs. So T&E was all that was required. The fitting also had the facility to switch other lights, and had an alarm output.

 
thanks both.lurch, would you use 3c&e for the overide?
Depends how I was wiring it. Usually feed the switch and run a 3c&e up yes. Also generally do that whether the light needs it or not FWIW, it's there then.

 
if its not black and white wire in three core to cover yourself, but all the lights i fit can be overidden by switching on and off with 1-2 seconds (timeguard, freidland). I tend not to fit any besides these as im fed up with replacing the cheap ones.

Did the NIC tell you to do it that way?

 
there is a thread about this somewhere, but in short

in the old colours

r = perm live

y = switched live

b = neutral

so if

r= brown

y= black

b= grey

why change the way things have always been done?

keep things simple.

 
i always thought you should use grey as the neutral to dis-associate black with being neutral.

 
thanks steptoe, i never thought about the colours of 3c before the change to be honest.i was only going with black as black was N in twin.

thanks
no probs paul,

its a very common mistake from newcomers,

thats why we are here,

we both learn.

 
thats why i thought sleeve the black, though does it matter? as long as its sleeved?
strictly speaking, NO,

you could sleeve the brown blue, the black brown, and use the grey as green/yellow,

wouldnt be best practice though.
