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?
Thanks, Fred C.
Hi Fred - Great Question
The PIR systems are currently offered with two configurations: Self contained Solar Powered units which provide their own power so no switch is needed. PIR room light controllers come as individual stand alone units or multiple networked controller systems complete with occupancy PIR sensor for room lighting control.
The unit is used to replace a standard 'dumb' multi button light switch to give automated control atlow prices. These units are typically control 1or more different Lighting Circuits @220VAC, and 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 be network connected to ION Supervisor or 3rd party devices and can act as burglar alarm and/or people, or room entry indicator.
Normal powered AC units have the built in PIR Motions Sensing System which are connected to normal power and you could have a switch ahead of the unit which would control the main power coming in.
However if the main power was shut off the PIR unit cannot function so it is not advised because it defeats the purpose of the PIR design and purpose with the exception of isolating individual units for manual on/off control, but again this would defeat the design of these units.
Be Careful and Be Safe - Never Work on Energized Circuits!
