Wire a light with PIR control

My question is, is it possible to have a electrical lighting system that can be operated with a Switch and a PIR?

If so how would the diagram look?

Hi Fred - Great Question
The PIR systems arecurrently offered with two configurations: Self containedSolar Powered units which provide their own power so no switch is needed. PIR room light controllers come as individual stand alone units or multiplenetworked controller systems complete with occupancy PIRsensor for room lighting control. The unit is used to replace a standard 'dumb' multi button light switch to giveautomated control atlow prices. These units are typically control1or moredifferent Lighting Circuits @220VAC, can be auto controlled plus auxiliary outputs are available for other controls such as heating/cooling/window blind/ceiling fan/floor heating etc

The occupation detection has the capability to benetwork connected toION Supervisor or 3rd party devices and can act asburglar alarm and/orpeople or room entryindicator. Normal powered AC units havethe built in PIR Motions Sensing System whichare connected to normal power and you could have a switch ahead of the unit which would control the main power comingin. Howeverif the main power was shut off the PIR unit cannot function so it is not advisedbecause it defeats the purpose of the PIRdesign and purpose with theexception of isolating individual units for manualon/off control, but again this would defeat the design of these units.

Be Careful and Be Safe - Never Work on Energized Circuits!
