No Neutral Wall Mounted PIR Detector
The PDS presence detection switch replaces a standard single gang light switch. It detects movement using a PIR sensor and turns the lights on, (either incandescent and fluorescent loads). An internal light sensor is provided for additional energy saving. When an area is occupied lighting is only switched on when the level of natural light is below a preset level. When an area is no longer occupied the lights will switch off after an adjustable time out period.
The detector should be sited so that the occupants of the room fall inside the detection pattern shown overleaf, at a recommended height of 1.2m to 1.5m. Note that the higher the sensor is installed the shorter the detection range will be.
Technical Specs
10 Amp incandescent lighting
6 Amp fluorescent lighting
3 Amp compact fluorescent lighting
3 Amp low energy lighting
3 Amp low voltage lighting (switch primary of transformer)
Fluorescent lighting (max 6 fittings recommended)
Fluorescent and compact fluorescent fittings with “switch start” ballasts - 6 ballasts maximum.
Power factor correction capacitors must be fitted.
Most fluorescent fittings have power factor correction capacitors fitted. If they are not present the unit may fail the installation procedure, in which case fit one capacitor per circuit with a minimum value of 1 micro F for every PDS or PDS-OV installed. Note that it is not necessary to fit a capacitor on every fitting.
For fluorescent lighting total power factor correction capacitance must not exceed 40 micro F.
