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. Although nominally 12V, the dimming output is not SELV and therefore should be treated with the same respect as mains with regard to wiring practice.
The 0V line of the dimming output is almost at Neutral potential.
4. The dimming control output should be connected only to the control input of the ballasts - never to other detectors.
5. Due to the fact that the photocell is on the ceiling looking down, it is not possible for measurements made with a lux meter on the working plane to remain
constant when daylight illuminates the ceiling and the working plane to a differing extent. Therefore, products of this type should be regarded as capable
of maintaining an APPROXIMATE light level only.
6. 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.
7. The detectors are extremely sensitive to movement; they must be mounted on a solid surface which has no movement whatsoever.
8.
This equipment should be used to control only those ballasts powered from the same phase as the detector.
