For mine I fitted a 2-gang plate, 1 switch for the PIR and 1 for
direct-on.
Rand 3+E, with 1 wire to the lamp.
This gives me a local Off switch, but it could be done with a single
2-way
switch, one way via PIR and the other to the lamp. Needs another way of
fully off.
Note: my PIRs are seperate from the luminaires.


Not an ideal solution. This will be going into a freinds' rented
property where and changes to the electrics cannot be DIY. Changing the
external 500W halogen floodlight for a "like for like" 10/20W using the
existing wiring and external junction box may not be noticed

The problem with some LED/PIR units advertised with a manual override is
that the manual override consists of setting the timer control to
maximum making it a simple on/off operation by applying/removing the
mains voltage. What is required is a normal PIR operation that is easily
overridden sometimes.


I recently fitted one of these.

Too soon for feedback on performance in practice but I was impressed by
the range of adjustments and by the way wireless remote worked from
inside the house (which allows manual override).
