When the bedroom door is opened a magnetic door contact opens and the controller initiates the power
supply. Power will remain on as long as the door is open. When the door closes the following steps are
automatically carried out by the system:
- The power supply is held on.
- For the next 10 seconds (adjustable) the system monitors the space for occupancy via sensor
- heads installed in the bedroom and en-suite whilst continuing to maintain the supply.
- If a person is detected in the room, then power will remain on until the door is opened again.
- If no occupancy is detected within the 10 second time frame power to the room will switch off.
The above process is repeated every time the door is opened and closed, ensuring power remains on if the
room is occupied, but is immediately turned off once the room is empty.
As a safeguard, if the power is off in a bedroom, but occupancy is detected, regardless of the state of the
door switch, the output will switch on and remain on until the door is opened again.
