Instructions

Note: HP2000 required for commissioning

MLS Digital Mid-Bay Detector: MLS2001DMBF/SM for DSI & MLS2001DALIMBF/SM for DALI ballasts

Only suitably qualified personnel should install this equipment.

Fixing

Flush Version: Depth required behind ceiling: 62mm from front flange plus an allowance for the minimum bend radius of
the cable. Sinking box fits into a 89mm diameter hole in ceiling tile or plasterboard ceiling. Note: If the sinking box is being
fitted to a hard substrate such as metal, increase the hole size to 91mm. To avoid damage to ceiling tile, do not overtighten.
No access above the ceiling is required.

Surface Version: The housing may be secured to a hard surface or a BESA box. The unit fits into the housing with a simple
bayonet action.

For aisle or corridor applications, there is
an optimum orientation for approach:

Note: When operating in 'Regulating Photocell' mode, a closed feedback loop is formed by the luminaire, the reflective
surface beneath, and the photocell. For this control loop to function correctly, the photocell must have a good view of the
reflected light only from the luminaire(s) under its control – NOT from adjacent luminaires not under its control. This means
that the higher the detectors are mounted, the further apart they must be in order to ensure that they see mostly 'their own
light'. Therefore, it is recommended that detectors are mounted on a pitch not less than 50% of the mounting height when
using the regulating photocell function.

Connection

Control of a group of luminaires is achieved via the detector’s two-wire digital control circuit. Each luminaire to be controlled
must contain a digital regulating type ballast with the appropriate DSI or DALI input. Ballast types must not be mixed.
Connect all ballasts in the control group (max 25) in parallel and also to the polarity-free digital output of the detector.

Each luminaire is controlled completely by its digital input and therefore would normally have a permanent power supply. If,
however, it is desired to have manual wall switches, any or all of the fittings in a controlled group may also be controlled in the
traditional way - by turning off the power. The control circuit will continue to operate properly even if some of the luminaires in
the group have had mains power removed.

The MLS Bus must be connected to the MLS Bus Network. An MLS Bus Power Supply is required for each network of up to
200 MLS devices. Refer to the MLS Bus Power Supply Installation Instructions before commencing any bus wiring.

It is imperative that the MLS Bus is wired in the correct type of cable. Normally this will be 1.5mm² unscreened twisted pair.
See Application Note AN4001 for details.

Do not connect mains to the MLS Bus wiring

‘OneSwitch’ Dimming

OneSwitch dimming affords local control to the end-user whereby a simple, momentary, push-to-make wallswitch can be
used to raise or lower the lighting level or to toggle the output ON/OFF. A short press of the switch (less than 1 second) will
toggle the output status while a longer press will raise or lower the output. Each time the switch is pressed, the direction of
dimming reverses. If the switch has not been pressed for 5 seconds, the direction will be up (brighter) - unless the output is
already above 90% in which case the direction is down. If the switch is held continuously, and the output reaches maximum,
the light output will remain at this level until the switch is released - a latching switch may be connected in parallel allowing
the occupancy detection to be overridden on (Note: If the initial direction was down, when the output reaches minimum it will
ramp back up automatically).

Setting the Regulating Photocell

This product is intended for use with high frequency regulating ballasts with digital control inputs. An infrared programming
tool, the HP2000, is required for programming the regulating light level set point.

Using the HP2000 Programmer, enter the Utilities menu and 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.

Additional feature acc essible under Utilities on HP200 0:

The factory default settings shown in the table below will be appropriate for most applications. However, the installer does have the
facility to re-programme all parameters using the HP2000 Programmer. These parameters may be re-programmed any number of
times and all settings will be retained in the event of a power loss.

Lens Mask

A lens mask (MBPIRLM) is available to mask end-of-aisle movement from being detected.

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

3. Although nominally 12V, the dimming output is not SELV and therefore should be treated with the same respect as mains
with regard to wiring practice. The 0V line of the dimming output is almost at Neutral potential.

4. The dimming control output should be connected only to the control input of the ballasts - never to other detectors.

5. 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.
