Changing Rooms and WC Areas

As changing rooms and WC areas can be unoccupied for long periods, uncontrolled lighting is particularly wasteful. Additional savings can be made through the control of extract fans and urinal flushing.

Linked Operation

These areas usually have an outer and an inner entrance door with a small lobby between. Opening the outer door and entering the lobby should trigger the main toilet/changing area lights. Monitoring the entrance alone is not sufficient. As WC areas tend to have little or no natural light, it is important that occupancy is also detected within the main area, ensuring that the exit route also remains lit.
Employing a master sensor within the small entrance lobby connected to bus sensors within the main area provides the perfect solution (LightSpot HD QuickLink Sensors).

Shower Room

If the area includes a shower room, an IP55-rated sensor (LS3200RIPF) should be considered.

Extract Fans and Urinal Flush Control

Further savings can be made by controlling extract fans in shower rooms and toilets.
In male WC areas, solenoid valves can also be incorporated with the sensor to operate urinal flush control.

Key Considerations and Application Notes

  • Linked operation of the lobby lighting with that for the main area.
  • Separate stand-alone sensors for associated areas to maximise savings.
  • Linked operation to ensure occupancy elsewhere in the facility sustains the lighting for the main area/exit route.
  • IP55-rated sensor for shower area.
  • Control of extract fans.
  • Water savings by controlling urinal flushing.
  • If the facility benefits from ambient natural daylight, occupancy and photocell control could both be used for the lighting but occupancy only for controlling urinal flushing.
