3. Fitting the infra red sensors
The infra red sensor picks up both direct and reflected signals. The 360
°
ceiling
mounted sensor included as standard will adequately cover most classrooms. A 150
°
wall mounted sensor is available for coverage of ‘dead end’ or non reflecting areas.
Normal room:
1 dome sensor
L-shaped room:
1 dome 1 wall sensor
Large room: 2 dome sensors

The infra red sensors need to be positioned so that they provide coverage of the
whole room. In large or strangely shaped rooms it may be necessary to fit additional
sensors.
The dome sensor is normally fitted near the centre of the room and as far away from
lights or other obstructions as possible.
