2 way switching for PIR floodlight

[alexknight0602]

Is there is any reason why 2 way switching wouldn't work for a PIR floodlight taking into account the PIR setting and the manual override mode??Obviously it would be wired correctly!
Just yes or no. No abuse please!

I've fitted one of those, supposed to act as a deterrent.
Not a bad idea.

As mentioned already, switch with LED will let you know when light is switched or PIR

I thought so because im sure when i second fixed one a while back it just had a permanent live terminal so it must switch internally!
In that case it would make it even easier isolating the pir light from the switch as it would just have a neutral and switch live going to it!

Remember you'd need to run a neutrai to the switches if you want LEDs or neons activating when switch is depressed.

You would be able to isolate it but you could not override this type of light to make it stay on

most will have a s/l terminal to feed a second light as a slave.

The Led flood light don't they just come with a short bit of 3 core flex

trying to bodge 2 way switching to a light fitting that is designed to be controlled exclusively by its own built-in independant pir sensor is just dumb beyond words no matter how many fookin wiring diagrams you want to put up.

so stop mincing about and tell the clueless customer their idea is a non starter.

Going by the OP, the light fitting is a bog standard PIR security light, in which case, they are NOT designed 'exclusively' to be controlled by their own PIR and any type of switching arrangement can easily be provided to override the PIR, or have I read things wrong?

 

[Guest55]

the whole point of a security light is to be left on 24/7 and be activated by its own movement & daylight sensor , its a pretty simple concept really.

and as tel mentioned earlier , the s/l terminal in your diagram is an output to slave lights from the pir so wiring it to a 2 way switch will achieve 2 fifths of F.A.

 

[davethsparky]

Or a switched live in to bring the light on as and when desired.
If the customer wants to switch the light on aswell as having a pir controlling it then what is the problem?

 

[Guest55]

youre assuming the light in question has the facility for both permanent and switched incoming supply......
cos 99% of the ones i've fitted / seen have only an output terminal to feed secondary units.

dont take my word for it though , crack on and fit it and await the customer phone call to say its not all working as they hoped and all the tedious hassle that follows.

Thanks
Ill be installing with a single switch. Now just down to the customer to decide whether they want their single switch internal or external.

Biff I'm afraid I'm not quite following you here.

The switched live terminal can be output or input or both, the pir just uses a relay to act as a switch between the perm live and sw live. Adding an override switch in parallel to this is no problem.

Some of them even have this override switch wiring in the instructions.

 

[D Skelton]

Exactly the point I was trying to make. Any PIR security light will have the l/s terminal for input to override the pir and/or output to feed slaves.
