Can you 2 way a PIR?

Yes it is possible and simple. Leave your existing 2 way switching as it is. Run a cable from the ceiling rose with permanent live, neutral and switched live and earth to your PIR.

Can you wire a PIR light to a switch?

You will need to disconnect your switch. Get some 3-core and earth wire, or use two T&E and use one core in one of them. Take the switch feed to your PIR live in and the PIR live out to your light. You need to take a neutral off the ceiling rose to the neutral on the PIR.

What is the blue wire on a motion sensor light?

Use the blue or yellow wire to connect to load (light fan motor etc). 1) Occupancy-green-wire connects to bare ground wire. 2) Single-pole switch being replaced has 2 wires. Take Single-pole switch wires and connect them to Occupancy-black-wire and Occupancy-red-wire.

Can I replace a light switch with a PIR?

You don’t need to replace the light switch, just install a PIR between the switch and light. Depending on how your light is wired, the switch might not have neutral anyway, so you’ll need to find that first (will be at the light end).

Can you 2 way a sensor?

Yes, you can, under code, but you will also need to have ‘real’ switches also installed. As far as the second part write on a bit of paper, in marker, and stuff it in the the motion sensor junction box.

Does a PIR need a neutral?

For the PIR, you would need to take a live and a neutral from the rose or JB, then a switched live back to the rose or JB to as before connect to the live on the fitting. You are going to have to replace the 2 core and earth with 3 core and earth.

Do I connect the blue wire to the black wire?

Connect the blue wires together or the blue wire to the black wire for lights. Follow the same step for ceiling fans without lights. This will allow you to add a light kit later on without having to rewire the fan. Tuck the wires back into the box.

Can you wire 2 motion sensors together?

The setup for most systems is straightforward. Mount the sensors to cover the areas you wish to be able to detect motion and activate. From the conventional switch, route a wire to each of the motion sensors and from each motion sensor a wire will need to be run to the light fixture.
