Connection Example
Single UC1200PF
Controlling water
LightSpot presence-detecting washroom control
Only suitably qualified personnel should install this equipment.
This is a high performance presence detector with photocell. The photocell can operate in three modes:
Passive, Active or Disabled. Further information can be found overleaf.
Fixing
The UC1200PF is suitable for flush mounting in a suspended ceiling tile, maximum 54mm thick and with a
minimum clearance of 125mm between the front surface of the tile and the hard ceiling behind. The UC1200PF
should be mounted in the centre of the group of luminaires to be controlled. Cut a 50mm diameter (64mm if
using an FR64 flush ring or PB64 plasterboard fixing kit) circular hole in the tile, feed the flying lead and detector
through the hole and secure into position with the locking ring. Twisting the locking ring will release the detector
should this be necessary.
Note:
Do not position within 25cm of a luminaire.
Solenoid Valve
The solenoid valve must be plumbed into the water feed to the urinal header tank and connected to the detector
using 230V cable.
Multiple UC1200PF
Larger areas can be covered by connecting extra units in parallel. The total load current must not exceed 6 Amps
in case only one unit is activated.

Important Additional Notes
1.
All terminals on this product are provided for final connections. It is not intended that the product be used as a junction box
for looping cables.
2.
A means for disconnection must be incorporated in the fixed wiring in accordance with the current wiring regulations.
3.
This equipment switches lights no more frequently than would a responsible human occupant. However, manufacturers of
some lighting types (e.g. ‘2D’ luminaires) may specify a maximum number of switching cycles in order to achieve a
predicted lamp life. Please check with the manufacturer of the luminaires to ensure that they are compatible with
automatic controls in this respect.
