Silver Series LightSpot with photocell

The Silver Series LightSpot 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

MS1201PSM / MS1221PSM - The housing may be secured to a hard surface or a BESA box. The unit fits into
the housing with a simple bayonet action.

MS1201PF / MS1221PF - Supplied with a sinking (dry lining) box for flush fitting. Sinking box fits into an 89mm
diameter hole in ceiling tile or plasterboard ceiling. To avoid damage to ceiling tile, do not overtighten. Depth
required behind ceiling: 62mm from front flange plus an allowance for the minimum bend radius of the cable. No
access above the ceiling is necessary.

Note: Do not mount within 25cm of a luminaire.

Important Additional Notes

1. Only suitably qualified personnel should install this equipment.

2. 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.

3. A means for disconnection must be incorporated in the fixed wiring in accordance with the current wiring regulations.

4. 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 and/or a minimum on-time 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.
