Installation and Commissioning Instructions

Fixing
Only suitably qualified personnel should install this equipment.
1. The COMRE 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 3.5m. 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 COMRE microwave detectors.
If two COMRE detectors are used at opposite ends of a corridor, facing each other, they must be at least
30m apart.
If two or more COMRE detectors are located in the same area they must be a minimum 5m apart and not
in each other's detection viewing angle.

Note: A means of disconnection must be incorporated into the fixed wiring in accordance with the current
wiring regulations.

Electrical Connections
The COMRE should be connected in accordance with the diagram below.
It is designed to control a switched load of up to 10 Amps.
When switching via the relay output, multiple detectors' relay outputs may be connected in parallel provided
the controlled load does not exceed 10 Amps.

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 ( ). A ten-second time delay is selectable to aid commissioning. COMAHP
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) 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.
ii) Photocell DISABLED
If the photocell is configured as DISABLED 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.
Programm the Photocell Set-pointsing
Method 1: Manual
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 screen briefly, COMAHP
following a download operation. The number represents the light level read immediately before the download
took place.
Tip: Turn the lights off (UTILITIES / REMOTE to measure the COMMAND/PLUS/GAMMA / IR / COMHC)
perceived light level with no contribution from the controlled lighting.
Method 2: ‘Teaching the Levels’
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) ait until the time of day when the natural light level is at the point If the chosen photocell mode is Passive, w

a photocell reading, adds 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.

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. 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.
3. 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.
