These PIR sensors can be used to replace a wall light switch to save energy when rooms are unoccupied.

The PIR wall switch fits into a 25mm deep single gang wall box (85mm x 85mm recessed or surface socket box) and be used in walls or ceilings.

At installation, the 'on time' can be set between one and sixteen minutes. If the sensor detects movement during the on period it resets the time period - in short if someone is moving in the space the unit keeps the lights or fan on.

The sensor can also be adjusted for light levels i.e. if the space benefits from natural light during the day the sensor can be set to operate only at night reducing energy costs further.

Maximum loads:

Resistive loads (i.e. incandescent lamps) - 2400 watts

Inductive loads (i.e. fluorescent and LED lights, fans etc) 720 watts.

Perfect for use in lavatories, public buildings, corridors, stockrooms etc.

Timer range: 1 Minute to 16 Minutes.

Has a detection angle is 120 degrees with a maximum distance of 8 metres.

The version sold with a switch allows you to choose between sensor operation and on.

NOTE: This unit requires a live and neutral supply to operate. A neutral wire may not be present in your existing switch wiring. If in doubt consult an electrician.

I need a switch like this please but the downlights I fitted use LED GU10 lamps , do you do a suitable switch like this that works with them and they won't flicker?
Yes, this would work with GU10 LED's.

can this be used with low voltage down lighters
Yes low voltage lamps are considered to be a resistive load, so 12v lamps can be switched without issue.

Is it possible to wire two sensors to control the lights on the stairs? (Top and bottom) Is it possible to do this or will it cause problems having two sensors?
It is possible, however, an electrician would need to wire it in a specific way to get this to work properly - depending on your setup.

Is this available in a stainless backing plate or can the plate be painted?
Plain white plastic is the only option. Plasti-kote paint may be a solution.

I am replacing a light switch in a downstairs toilet that operates both the light and fan. The light switch only has two wires, live and neutral with an earth fixed to the mounting. Where do I attach the live wire - or is it the incorrect unit ?
If your existing light switch has only two wires in the back box it is highly likely that one is live and the other a switched live ie live coming to the switch and a wire coming away that becomes live when the switch is on. All movement sensors require a live and a neutral to work. You could look at using a ceiling sensor, this could use the live and neutral going to the light and operate both light and fan. The wall switch could then be removed. Do consult an electrical for more specific advice.

Do you have a model that works with only two wires so I can replace a pull cord switch.
There’s no PIR that can operate on just a live wire you need a neutral for them all to work - sorry

I currently have two wires common and a live out. There is a neutral cable in a connection block. Would this be used ok?
So long as this fitting can connect to a live and a neutral wire this will be okay. If in doubt we would suggest contacting an electrician.

My current kitchen light switch wiring is 2 red wires wrapped together to be a top live in, 1 red wire at bottom as live out, and earth attached inside the box. Will I be able to use the pir switch and if so how would I wire it or would I need an electrician?
This PIR switch required a neutral wire, it sounds like your installation doesn`t have this. An electrician may be able to run a neutral wire from the first or last light in the circuit.

When you switch off the PIR will it turn the lights on by passing the sensor.
The switch gives you the options of 1) The PIR being on (per your set time) 2) The lights being on as normal so there is effectively no off option.

Does this have two live and two neutral connectors? This is the set up of the switch that its`s replacing
This has a live in, live out and a neutral. To wire this with 2 live and 2 neutral you just need to put the 2 neutral wires into the single neutral connector block.

Could I use this switch at the bottom of my stairs? I can turn hall light and upstairs light on at this point ...but only the upstairs light when upstairs ..ie 2 switches down but only one up
Your existing installation uses 2-way switches. You cannot use this product as the product only supports one way switching. Consult an electrician if you are unsure.

Can the sensor switch be used in a bathroom?
If you are planning on replacing your switch in your bathroom, we are certain that this would be in the right position, If you are planning on having it in a new position, you would need contact your electrician as there are guidelines where these can be installed in the bathroom.

Is this sensor a tree wire system?
Presuming you mean a `three` wire system, this requires a live and neutral wire, it requires no earth but has an earth termination block.

Im thinking of mounting this at the top of a stairs, will it pick up motion at the bottom? Its a 3 metre distance with a pitch of 47 degrees.
More than likely not as your requirements are quite specific. Equally the switching for your lighting will need to be 2-way switchable.
