SYSTEM AND FUNCTIONS
2.1.3.2 LIVELINK LIGHTGRID SENSOR PIR
The LiveLink LightGrid Sensor PIR passive infrared sensor is ideal for
mid-sized to large offices, conference rooms, meeting rooms and class-
rooms. Due to its size, it can be used as a recessed or surface-mounted
ceiling sensor. The sensor is highly compact and blends harmoniously
into the ceiling design thanks to its discreet appearance. In conjunc-
tion with the LiveLink LightGrid Controller, the sensor is used to detect
changes in movement of light. The sensor is connected to the controller
via a separately orderable RJ10 cable.

2.1.3.3 SENSOR PLACEMENT
Presence detection
• The detection range of the sensor must be considered (see the
sensor data sheet). On the one hand, the sensor should detect
working and movement areas in the room, but in the case of au-
tomatic switch-on (fully automatic, see chapter "Behaviour in op-
eration"), it should also detect the entrance if possible so that the
light is switched on early. If the detection range of a sensor is not
sufficient, further sensors must be planned in.
• If high frequency sensors or radar sensors are used it must be
considered that the detection may pass through thin walls. Also,
the narrow detection range (see product data sheet) must be tak-
en into account.
