Am intending to install a Delta PIR Security Sensor DET100. which has self contained sensor & LED light.
Wiring configuration has me puzzled.
My existing light power source is active & neutral with earth disconnected. Unit does not trigger, as previously, when configuration is confined to live & neutral only.
The PIR red wiring is a Switched active permanently wired to the fitting.
Wiring configuration seems to suggest that a neutral loop between Blue & red is required to activate device ?
There is no intention to connect other LOAD appliances only the self contained sensor/ light unit.
Grateful of any guidance.
Best Regards Alan.
