To Test with COMHC Hand-held Controller
Once the Command Plus Luminaire Controllers have been installed within the luminaires, the COMHC may be used to
dim and brighten luminaires and to switch them ON and OFF. One of 6 different lighting scenes can also be recalled.
Commissioning
Detectors are supplied factory pre-set which ensures the lighting will switch on automatically as soon as power is
applied. Final commissioning of the detectors requires the use of the COMA P Programmer. H
Commissioning Detectors using the COMAHP Programmer
It is important that the Programmer be held perpendicular and at a distance of between 0.5m and 2m from the
detector.
1. Switch on by pressing button (and unlock with top left rectangular button).any
2 the programmer the detector programmer. Point at and press the DOWNLOAD button. The will confirm the
product’s identity and call up the correct menu of parameters and current settings.its
3. Use a combination of UP, DOWN, FORWARD and BACK buttons to navigate the parameter menu, selecting
options for each shown.
4 programmer detecto. When options for all parameters have been selected, point the at the r and press the
UPLOAD button. The luminaire(s) will switch off briefly during the programming process.
5 programmer. After a short period of inactivity (default 5 minutes), the hibernates retaining the most recent settings.
OneSwitch Dimming
OneSwitch dimming affords local control to the end-user whereby a simple, momentary, push-to-make wallswitch can
be used to raise or lower the lighting level or to toggle the output ON/OFF. A press of less than 1 second will toggle the
output status while a longer press will raise or lower the output. Each time the switch is pressed, the direction of
dimming reverses. If the switch has not been pressed for 5 seconds, the direction will be up (brighter) - unless the
output is already above 90% in which case the direction is down. A wiring diagram is shown left.
Important Additional Notes
1. A means for disconnection must be incorporated in the fixed wiring in accordance with the current wiring regulations.
2. 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.
3. The dimming control output should be connected only to the control input of the ballasts - never to other detectors.
4. This equipment should be used to control only those ballasts powered from the same phase as the detector.
5. Do not connect mains to the Command Plus bus.

6. It is imperative that the Command Plus bus is wired with the correct type of cable; normally it should be 1.5mm
unscreened twisted pair. Please read Application Note AN4017 for more details.
7. 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.
8. This equipment switches lights no more frequently than would a responsible human occupant. However,
manufacturers of some particular 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.
9. Some devices in this product range feature a silvered surface finish; this is intended for decorative purposes only.
Care should be taken to avoid accidental separation of the silvered coating from the product. If the unit is built into a
luminaire that is subsequently wrapped in film having adhesive properties, it is recommended that a layer of suitable
packaging material be used to protect the silvered area.
