Installation and Commissioning

Instructions

Introduction

The MLSM2002CDRDHPBW offers high performance presence detection with 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 initial
CDW12U5/CDH4U5/CDH8U5 system commissioning. When properly installed and connected it is an SELV device.

Installation Guidelines

1. The Plasterboard Mounting Kit allows discreet mounting in plasterboard or suspended ceilings.

2. The connecting cable must not be extended.

3. Artificial light illuminating the Mini Detector Head must only be reflected from the room, i.e. there must be no
direct illumination.

4. In order to achieve satisfactory light-level regulating operation, a detector must observe a substantially greater
proportion of artificial light from the luminaire(s) under its control than from neighbouring luminaires not under its
control.

5. Please note that this unit is for extra low voltage use only. DO NOT CONNECT TO THE MAINS.

Mounting Details

Control Module - is designed to be mounted within a luminaire on fixing centres of 135mm.
The interconnect cable between the detector head and the control module should be routed away from other

luminaire’s internal wiring and away from the lamp end-caps.

Mini Detector Head - slots into the Plasterboard Mounting Kit (Fig.1).
Plasterboard Mounting Kit - allows the Mini Detector Head to be installed discreetly in plasterboard or

suspended ceilings of up to 25mm thickness.
The unit fits into a 60mm hole in the ceiling. Fold back the spring clips (Fig. 2) to insert the unit. Once in position,

the clips will automatically clamp down and the unit will appear as shown (Fig.3).

Connecting

The MLSM2002CDR 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). Note that the

maximum allowable cable length between the MLSM2002CDR and the LCM is 100m.

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 control module into the modular socket labelled "CD Box Connection" on the top of
the control module.

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 re-programmed any number of times.

Setting the Regulating Photocell

Using the QuickSet Pro, enter the Utilities menu and choose ‘LightSpot/MLS/LCM’, then select ‘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

Now the desired switching light level must 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, enter the
Utilities menu and select 'IR Remote', then ‘HC5'. 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.

Important Additional Notes

1. 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.

2. 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.
