Mid-Bay LightSpot with photocell: MS1200PMBF
This is a high performance presence detector with photocell. In all operating modes, the photocell can hold lights
off as a vacant area becomes occupied, and if the light level falls too low during the period of occupancy, the lights
switch on. In 'Passive Mode' the lights do not switch off whilst the area is occupied no matter how much light is
measured. In 'Active Mode' the photocell is able to switch the lights off whilst the area is occupied.
Fixing
Verify the small arrow on the bezel is inline with arrow on the main body.
This detector 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 detector 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:
Minimum mounting pitch (spacing) utilising the photocell = 0.5 x mounting height.
For aisle or corridor applications, there is an optimum orientation for approach, clearly indicated on the front of the product.
