Installation and Commissioning
Instructions
(HC5A or QuickSet Pro required for Photocell Commissioning)
Introduction
The MLS2500CDR Mid-Range Detector offers high performance, directional presence detection
and contains a photocell to monitor total light levels allowing the light output of dimmable
luminaires to be adjusted to suit the natural light level available. It also contains an infrared port
that can be used both for local control from a hand-held device when in service, and for
CDW12U5/CDH4U5/CDH8U5 system commissioning. Properly installed and connected this is
an SELV device.
Positioning
Position the detector where it has a good "view" of the space to be controlled. An ideal location is in
a corner adjacent to the entrance of a room or at one end of a corridor. Suitable fixing heights are
between 2.5m and 3.5m.
This is an extremely sensitive movement detector. It is therefore essential that it be installed on a
rigid surface that will not itself be subject to any movement or vibration.
Microwaves can penetrate lightly built partitions, glass etc and thus movement in adjacent spaces
may cause spurious triggering if the orientation and sensitivity setting of the detector is not
managed carefully.
This product is not recommended for applications where there are large areas of metal, e.g. metal
ceiling panels or metal flooring, as unpredictable sensitivity may result.
Do not mount within 0.25m of a luminaire.
Fixing
The MLS2500CDR Semi Flush Version - Use a hole saw to cut a 76mm diameter hole into
the ceiling tile. The flush ring is designed to clamp the ceiling tile beween its two halves.
Separate the detector from the under-ceiling half of the flush ring by loosening the locking screw so
that about 3mm of thread is visible and twisting the detector anticlockwise
.
Align the mounting screw holes of the above-ceiling half of the flush ring with those of the backbox
and position both above the hole in the ceiling tile. Now offer the below-ceiling half of the flush ring
to the underside of the ceiling tile and align the mounting screw holes with those above. Note that
the locking screw tab on the under-ceiling half of the flush ring should be directly below the similar
tab on the backbox and the arrow symbol on the inside of the backbox should point into the
controlled area.
Insert the mounting screws through both halves of the flush ring and engage them in the brass
inserts of the backbox. Final adjustments to the orientation of the detector can be made before the
mounting screws are tightened to clinch the ceiling tile between the two halves of the flush ring.
The MLS2500CDRSM Surface Mounted Version - Separate the detector from its backbox
by loosening the locking screw so that about 3mm of thread is visible and then twist the
detector anticlockwise to release it from the backbox.
.
The fixing holes in the backbox allow for mounting onto a BESA box or directly onto a rigid surface.
The arrow symbol on the inside of the backbox should be aligned to point into the controlled area
before the fixing screws are finally tightened.
Connecting
The MLS2500CDR connects to the LCM via an eight core, RJ45 plug terminated, patch lead. All
such patch leads must be segregated from mains wiring to preserve the detector SELV
status that is provided by the LCM design.
Ready-made patch leads in lengths of, 3m, 5m and 10m are available from Ex-Or. (See back page
for Part Numbers.)
Where it is a requirement that the patch leads are protected by conduit it may prove more
convenient to run the cables unterminated and attach the RJ45 connectors afterwards. In this case
the cable used should be 4-twisted pair, 24awg multistranded, unscreened data cable to Category
5E standard, (e.g. Belden Datatwist 350). No strain-relief hoods should be fitted to the insulation
displacement RJ45 connectors, due to the limited space available above the emplaced detector.
The wiring scheme used should follow either the T-568A or the T-568B Ethernet standards, and
must give "1-1", "straight-through" connectivity between the two RJ45 connectors for all eight
cores. Note that this detector is not an Ethernet device and cannot be used with network
Hubs and Switches.
Plug the RJ45 connector at the detector station into the modular socket labelled "To CD Box" on the
top of the detector module and offer the detector to the flush ring or backbox so that the arrow
symbol on the detector label points in the same direction as the arrow symbol inside the backbox.
When the multi-tab bayonet fitting is engaged, twist the detector clockwise to retain it and tighten
the locking screw until the head is flush to secure it.

Commissioning
In the CDW12U5 and CDH4U5/CDH8U5 systems, all configuration information is held within the
LCMs themselves, not in individual detectors. Most of the configuration items are set up with the aid
of a dedicated programme running on a portable PC which communicates with the LCM either by
an infrared link, via one of the attached detectors, or by a specialised serial link into the LCM itself.
However, when setting the actual light levels around which dimming or switching decisions are to be
made, the system allows the commissioning engineer the same convenience as if he were dealing
with traditional stand-alone detectors. An infrared programming tool, the QuickSet Pro or HC5A, is
used to set the controlling or switching set-point for the photocell. In all cases the setting is then
transmitted from the detector to the LCM, where it is uniquely associated with the detector number
being dealt with and will be preserved in the event of power failure. All settings can be reprogrammed any number of times.
Setting the Regulating Photocell
Using the QuickSet Pro Programmer, enter the Utilities menu and select ‘LightSpot/MLS/LCM’ then
‘Set Light Level’. Use the ‘up’ and ‘down’ buttons to manually adjust the light output from the
luminaire(s) and when at the required level press and hold ‘OK’ to store. The luminaire(s) will blink to
acknowledge a successful store operation.
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.
Setting the Switching Photocell
The desired switching light level must now be arrived at, either by waiting for an appropriate time of
day or by a combination of manually switching off lights and perhaps masking windows. Using the
QuickSet Pro Programmer, enter the Utilities menu and select ‘LightSpot/MLS/LCM’ then 'IR
Remote'. Scroll down to 'Scene 1' and press and hold the 'OK' button to store. The luminaire(s) will
blink to acknowledge a successful store operation
Testing
Detectors can be put into a temporary 10-second Off Delay mode to check their sensitivity and
range settings using the QuickSet Pro’s Walk Test option (found under ‘Utilities’). This mode
expires automatically after a few minutes.
