Fixing
Only suitably qualified personnel should install this equipment.
1. This is an extremely sensitive movement detector; it is essential therefore that it be installed on a rigid
surface that will not itself be subject to any movement or vibration.
2. Before isolating the circuits to be switched, check that all lighting is fully operational and that there is no
moving equipment or machinery within the monitored area which may cause nuisance switching.
3. Position the detector where it has a good forward “view” of the area to be controlled. Ideal mounting
location is normally in a corner by the entrance or at one end of a corridor at a height of 2.5 to 4m. Do not
mount within 25cm of a fluorescent fitting.
Please note that this product uses microwave technology to detect occupancy and is not recommended
for applications where there are large areas of metal, e.g. metal ceiling or panelling, as unpredictable
sensitivity may result.
Also, microwave presence detection is not completely attenuated by materials such as plasterboard,
wood and glass, so the possibility of unwanted presence detection through office partitions should be
considered when determining detector positioning and sensitivity settings within the intended
application.
4. Separate the detector from its back-box by loosening the locking screw so that approximately 3mm of
thread is visible and then twisting the detector off the back-box. Note the arrow symbol moulded into the
bottom of the back-box. The fixing holes allow for mounting on a BESA box or direct to a rigid surface.
Secure the back-box firmly to a rigid surface so that the arrow points into the controlled area.
4a. For semi-recessed mounting, a 76mm (or 89mm in the case of versions with the suffix CFL or THETA)
cut-out is required.
It is recommended that these detectors be ceiling mounted. Where this is not possible, the wall-mounting kit
(COMREWMK - see below) must be used.

Vertical installation
Use this method of mounting for racking aisle
applications and where adjustment in the
vertical plane will give improved control over
the precise point of entry detection.
Horizontal installation
For general applications where
ceiling mounting is not convenient
and wide angle coverage in the
horizontal plane is desirable.
The COMREWMK can be
screwed to a hard surface or the
lid of a conduit stop-end box.

Positioning COMRED/COMREY microwave detectors.
If two COMRED/COMREY detectors are used at opposite ends of a corridor, facing each other, they must
be at least 30m apart.
If two or more detectors are located in the same area they must be a minimum 5m apart and not in each
other's detection viewing angle.

Electrical Connections
This unit should be connected in accordance with the diagram below.
The Regulating Detector is designed to control up to 25 DSI or DALI ballasts, a switched load of up to 10 Amps
or a combination of the two. When controlling DSI or DALI ballasts the ballast types must not be mixed.
The DSI or DALI input terminals on the ballasts should be connected in parallel with each other and to the
Polarity-Free Digital Output terminals of the detector. Each DSI or DALI luminaire is controlled completely by
its digital input and therefore would normally have a permanent power supply. Turning the power off to some
lights within a control circuit will not affect the operation of those lights that remain powered and under the
control of the detector.
When switching via the relay output, multiple detectors' relay outputs may be connected in parallel provided
the controlled load does not exceed 10 Amps. If digital ballasts are also being controlled, the digital outputs
from different detectors must never be connected one to another, even if they are of the same type.

Commissioning
The units are supplied with the factory default settings shown below which render commissioning
unnecessary in many applications. To make use of the programmable settings, an infrared commissioning
tool is required (COMAHP). A ten-second time delay is selectable to aid commissioning.
Sensitivity to Movement
While the factory settings will be correct for many applications, the sensitivity can be adjusted if required.
ON Sensitivity: This sets the detector’s range when the lights are ON. Choose setting from 1-100 where 1 is
lowest and 100 is maximum. (Note: Choose the lowest level possible to give adequate detection.)
OFF Sensitivity: This sets the detector’s range when the lights are OFF. Choose % setting from 10% to
100% where 10% = 10% of ON Sensitivity and 100% = same as ON Sensitivity. This is an approximation and
should be tested on site during commissioning.
Like all programmable parameters, the sensitivity settings will be retained in the event of a power failure and
can be re-programmed any number of times.

Photocell Control
i) Regulating Photocell
Regulating photocell control tries to maintain a constant level of total illumination in the space controlled by
dimming and brightening the controlled luminaires to compensate for changes in illumination from other
sources.
With the photocell configured as DISABLED the Regulating Control module is influenced only by the BRIGHT-
OUT setting. BRIGHT-OUT = YES allows it to hold-off the lights at the start of occupancy if natural light already
exceeds SET-POINT LOW and to extinguish the lights if total light, during occupancy after the controlled
luminaires have been dimmed to minimum, exceeds SET-POINT HIGH continuously for a period equal to the
OFF DELAY . The lighting is restored immediately if the illumination level subsequently drops below SET-
POINT LOW.
If the photocell is configured for ACTIVE or PASSIVE control of the relay switched load then the Regulating
Control module adopts the decision made by the Switching Control module in the case of turn-on inhibit on
entry, but still obeys the BRIGHT-OUT YES/NO setting with regard to turn-off during occupancy.
ii) Switching Photocell (PHOTOCELL: ACTIVE or PASSIVE)
Both ACTIVE or PASSIVE modes hold off the controlled lighting on entry when natural light is sufficient, i.e.
SET-POINT LOW is exceeded, but only ACTIVE mode will extinguish the lighting if natural light increases
sufficiently during occupancy, i.e. SET-POINT HIGH is exceeded continuously for a period equal to OFF
DELAY. The lighting is restored immediately if the illumination level subsequently drops below SET-POINT
LOW.
iii) Photocell DISABLED
If the photocell is configured as DISABLED for relay Switching Control it will have no effect on the control of that
load, which will be ON continuously during periods of occupancy unless commanded OFF via manual switch
or infrared control. The photocell readings are still available for use by the Regulating Control module while in
this mode.
Programming the Photocell Set-points
The parameters SET-POINT LOW and SET-POINT HIGH program the detector’s photocell response
The SET-POINTS can be manually programmed as numbers between 1 (darkest) and 1023 (brightest).
This number is not scaled to correlate with ‘lux’ measurements made using a light meter, but nevertheless is a
true representation of the light level perceived by the detector. To assist with finding the appropriate SET-
POINT settings, the light level currently perceived by the photocell can be viewed on the COMAHP screen
briefly, following a download operation. The number represents the light level read immediately before the
download took place.
Tip: Turn the lights off (UTILITIES / REMOTE using the COMAHP COMMAND/PLUS/GAMMA / IR /
COMHC) to measure the perceived light level with no contribution from the controlled lighting.
Alternatively the SET-POINTS can be configured semi-automatically;
i) The Primary Interest is the Regulating Control Output.
With the photocell configured as DISABLED:-
Using COMAHP (UTILITIES / COMMAND/PLUS/GAMMA / SET LIGHT LEVEL) or COMHC (+,- Scene 1)
set the required light output from the controlled luminaires and then press and hold OK (COMAHP) or Scene
1 (COMHC) until the controlled lights "blink" to indicate that a new SET-POINT LOW has been stored and a
calculated SET-POINT HIGH has also been inserted. Using the COMAHP the photocell can now be re-
configured as ACTIVE or PASSIVE if required.

ii) The Primary Interest is the Switching Control Output
With the photocell configured as ACTIVE or PASSIVE:-
1) If the lights are not already on, switch them on manually by pressing ‘UTILITIES /
COMMAND/PLUS/GAMMA / IR COMHC / ) or "+" (COMHC)REMOTE / Luminaire+ / OK’ (COMAHP .
Fluorescent lights do not reach full output until up to 15 minutes after being switched on, so ensure that
the lights are fully warmed up before continuing.
2) Wait until the time of day when the natural light level is at the point below which you want the lights would
to be on, and above which you want the lights to be on.would not
3) Start the internal self-programming mechanism by pressing ‘UTILITIES / COMMAND/PLUS/GAMMA /
SET LIGHT LEVEL / OK’ (COMAHP) or Scene 1 (COM C) The detector takes a photocell reading, adds H .
a small amount and stores the value in SET-POINT HIGH. Then it turns the lights off, makes another
measurement and stores the value in SET-POINT LOW. The lights now switch on again to acknowledge
a successful programming operation.
The two switching thresholds have now been set, and the difference between them is equal to slightly more
than the contribution made by the electric lighting. This is the perfect amount of hysteresis to ensure that the
lights will not oscillate.
OneSwitch
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 toggle the output of the unit ON or OFF. A short
press (less than 1 second) toggles all outputs from OFF to ON or from ON to OFF. A long both both either both
press will ramp the digital output either up or down with no effect on the volt-free output. If the output prior to
pressing the switch is above 90% the output will ramp down; if below 90% it will ramp up. If the latest press and
the current press are within 5 seconds of each other it will ramp in the opposite direction.

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. 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.
3. Take care when choosing a location for this equipment since this type of device is capable of detecting large
moving metal objects well beyond the normal range at which it is sensitive to human targets.
4. Please note that, although configurable as a regulating photocell, [closed-loop dimming according to daylight],
due to the probable corner-of-room location where there will be excessive influence by daylight reflected from the
walls, this product is not intended to achieve precise light level regulation measured on the working plane.
5. 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.
