LiveLink corridor sensor with DUAL HF technology, with twin direction characteristic and DALI interface for connection to a LiveLink control unit, for daylight-dependent control and presence detection. With integrated light sensor for daylight-dependent control and two integrated HF sensors for presence detection. Constant light control with switch-off function with sufficient daylight. Presence detection is independent of temperature, range to 10 m in two directions on one axis. Electrical supply via the DALI interface of the control unit. Settable switch-off delay time, optionally in automatic mode (automatic on, automatic off) or semi-automatic mode (automatic off, manual on). Special IQ mode for automatic adaptation of delay time to room use. Stepless setting of range. Temperature range: -25°C - +55 °C. Presence sensor is ideal for detecting radial motion towards the sensor. Detection angle: 360° with 140° aperture angle, also through e.g. glass, wood, lightweight partition walls. Detection range: max. 10m x 3m in each direction, steplessly electronically settable with a recommended mounting height of 2.5m to 3.5m ceiling height. Frequency range: 5.8 GHz. Transmission capacity: < 1 mW. Degree of protection IP20.
