D HC5 or D HP2000 required for Photocell Commissioning
Important installation information!
Installation and commissioning may only be done by an authorised
electrician. Mains power (230V~/50 Hz) to electrical equipment
must be switched off during installation. Applicable laws and
standards of the country in which the device is operated must be
observed!
D MLS2500CDRR4 and D MLS2500CDRSMR4
Mid-range Directional Microwave Detectors with Photocell
for use with the D CDW12U5 Programmable Connect
Digital Box
The D MLS2500CDRR4 Mid-Range Detector offers high perfor-
mance, 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 con-
trol from a hand-held device when in service, and for D CDW12U5
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 trigge-
ring 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.
Note:
Do not mount within 0.25m of a luminaire.

Fixing
D MLS2500CDRR4 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 adjust-
ments 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.
D MLS2500CDRSMR4 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 D MLS2500CDRR4 connects to the D CDW12U5 Connection
Box 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 D CDW12U5 design.
Ready-made patch leads in lengths of 2 m, 3m, 5m and 10m are
available from PEHA. (See page 7 for Part Numbers.)
Where it is a requirement that the patch leads are protected by con-
duit 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 displace-
ment 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.
