Abstract
A zoned interactive control area (10) wherein an architectural space is divided in to a plurality of zones (16), each having its own sensor (22) and zone lights (18). In a normal operating mode (50) the sensors (22) are used to detect the presence of a person such that the zone lights (18) can be turned on and/or adjusted for light level. Each zone light (18) also has a light sensor (24) used, at least in part, for communication with the other zone lights (18), such that the light level can be adjusted not just in response to a presence in the respective zone (16) but also in response to presence in other zones (16). According to a security method (70) when the zone lights (18) are not in use for normal lighting (as when they are turned off) then if the sensors (22) detect the presence of an intruder the zone lights (18) flash to deter the intruder and also communicate the fact of the presence of the intruder to the other zone lights (18) via the light sensors (22).
