<p>Detector unit for a lighting control system A lighting control system (1) comprises a light (5), a power source (2) anda detector unit (3) having a first part (9) detachably coupled to a second part (11). The lighting control system (1) is operable between: an operating configuration, in which the system is arranged to control power to the light (5) in response to an output from a sensor in the second part (11) of the detector unit (3), and a maintenance configuration in which the second part (11) of the detector unit (3) is de-coupled from the first part (9) of the detector unit. The lighting control system (1) is arranged such that in the maintenance configuration the power source (2) is electrically connected to the light (5) through the first part (9), such that the light (5) is on despite the second part (11) being de-coupled from the first part (9).</p> |
