PRE3205-AH
The PRE3205-AH ceiling mounted, multi-directional photocell allows the precise measurement of light either as a lux level on the working plane (i.e. desk surface) or as relative brightness from a window. With its highly accurate photocell, selectable time delay and adjustable switching differential, this device optimises the balance between natural and artificial lighting for a building’s occupants. An adjustable switching differential is available with a 1–10V analogue output or a DSI output. The ALC30 twilight switch has a lux level sensor. The lighting will be turned on or off when the ambient light reaches the preset level or after a preset time delay. |
