MLS2000PF - MLS Digital Detector with photocell

Only suitably qualified personnel should install this equipment.

MLS Digital Detectors are the high-performance, communicating, presence detectors at the heart of the advanced
lighting management system known as The Ex-Or MLS Digital. This detector is equipped with a passive photocell
designed to hold lights off when areas become occupied if the daylight contribution is high and to switch lights on in
occupied areas as the daylight contribution falls. Please note that the photocell will not switch lights off in occupied
areas.

Fixing

The detector is suitable for flush-mounting in a suspended ceiling tile, maximum 54mm thick with a minimum
clearance of 125mm between the front surface of the tile and the hard ceiling behind. It should be mounted in the
centre of the group of luminaires to be controlled. Cut a 50mm diameter (64mm if using an FR64 flush ring or
PB64 plasterboard fixing kit) circular hole in the tile, feed the flying leads and detector through the hole and secure
in position with the locking ring. Twist the locking ring to release the detector if necessary.
Note: Do not position within 25cm of a luminaire.

Connection

The detector is supplied with two flying leads. The mains lead should be taken into the nearest luminaire from
where it will pick up its 230V supply. Control of a group of luminaires is achieved by connecting all the luminaires
in a group (typically four) in parallel with the switched live output of the detector. The MLS Digital Bus must be
connected to the MLS Digital Bus wiring network to enable communication with the rest of the system. An MLS
Bus Power Supply is required for each network of up to 200 MLS Digital Detectors. Please refer to Bus Power
Supply installation instructions prior to commencement of any bus wiring.

It is imperative that the MLS bus is wired with the correct type of cable; normally it should be 1.5mm unscreened

2

twisted pair. Please read Application Note AN4001 for more details.

Do not connect mains to the MLS bus.

Commissioning

Detectors are supplied factory pre-set which ensures the lighting will switch on automatically as soon as power is
applied. Final commissioning of the detectors, including assigning to zones, requires the use of the QuickSet Pro
Programmer.

Commissioning Detectors using the QuickSet Pro Programmer

It is important that the Programmer be held perpendicular between 0.5m and 2m from the sensor.

1. Switch on by pressing any button (and unlock with top left rectangular button).

2. Point the programmer at detector and press the DOWNLOAD button. The programmer will confirm the
product’s identity and call up the correct menu of parameters and their current settings.

3. Use a combination of UP, DOWN, FORWARD and BACK buttons to navigate the parameter menu, selecting
options for each shown.

4. When options for all parameters have been selected, point the programmer at the detector and press the
UPLOAD button. The luminaire(s) will switch off briefly during the programming process.

5. After a short period of inactivity (default 5 minutes), the programmer hibernates retaining the most recent
settings.

Setting the Photocell

The light level should be set at a time when the ambient light level is equal to the level at which it would be
desirable for the photocell to become active. This can be achieved in the following ways:

1. Wait until the appropriate time of day.

2. Create the desired level by turning lights on or off as required and/or opening or closing window blinds etc.
At this point the photocell can be commissioned correctly.

Setting the photocell using a QuickSet Pro Programmer

1. Point the programmer at the detector and press the DOWNLOAD button. The programmer will confirm the
product’s identity and call up the correct menu of parameters and their current settings.

2. Select UTILITIES, followed by LIGHTSPOT/MLS/LCM, then IR REMOTE and HC5.

3. Select SCENE 1 in the display while pointing the progammer at the detector (as in any programming
operation). Press and hold the OK button until the lights acknowledge the command - i.e. they either turn on if
they were previously off or briefly turn off, then back on, if they were on at the start of programming.

Setting the photocell using an HC5A Hand-held Controller

1. Point the HC5A at the detector.

2. Press and hold the ‘1’ button until the lights acknowledge the command - i.e. they either turn on if they were
previously off or briefly turn off, then back on, if they were on at the start of programming.

Note: In all cases the photocell will make its measurement and store it in non-volatile memory (i.e. the set-point will
be retained in the event of power loss).

Important Additional Notes

1. A means for disconnection must be incorporated in the fixed wiring in accordance with the current wiring regulations.

2. 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.
