MLS2001AF & MLS2001ASM - MLS Digital Detectors for use with Analogue 1-10V Ballasts
Note: Connections to this equipment should be made by a suitably qualified person and in accordance
with the current wiring regulations.
MLS Digital Detectors are the high-performance, communicating, presence detectors which lie at the heart of
the advanced lighting management system known as The Ex-Or MLS Digital. These detectors are equipped
with a regulating photocell to work with analogue 1-10V ballasts.
Fixing
MLS2001ASM - The housing may be secured to a hard surface or a BESA box. The unit fits into the housing
with a simple bayonet action.
MLS2001AF - Depth required behind ceiling: 62mm from front flange plus an allowance for the minimum bend
radius of the cable. The sinking box fits into a 89mm diameter hole in ceiling tile or plasterboard ceiling.
To avoid damage to ceiling tile, do not overtighten. No access above the ceiling is necessary.
Note: Do not mount within 25cm of a luminaire.
Connection Overview
Each luminaire to be controlled must contain an analogue regulating type ballast with the appropriate analogue
input. Ballast types must not be mixed. Connect all ballasts in the control group (maximum load 6 Amps) in
parallel and also to the analogue output of the MLS Detector.
The MLS Bus must be connected to the MLS bus wiring network. An MLS Bus Power Supply is required for
each network of up to 200 MLS 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.

‘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). A wiring diagram is shown above.
