MLM INTEGRATION WITH BMS
Occupancy override
The MLM24 system contains an internal occupancy override feature shared with an external BMS. See the BMS
(BACnet) table for Multi-state Output 60-119.
The system can be forced into an occupied or unoccupied state. The default is for normal operation. Again the
Master Command/Control override need to be set:
Light Switch operation
The light switch is designed to operate in conjunction with occupancy sensors, with one light switch unit in-
stalled for each control zone.
The unit contains two output channels, Switch A and Switch B to power two separate lighting arrays (See hard-
ware specification).
Each channel can be configured for manual on, manual off or to switch following occupancy sense delay 1 or
delay 2.
Manual on/off does not require the control override enable to be selected.
Each channel contains a Normally Closed relay output, i.e. power to the lighting arrays stays connected by de-
fault.
If Delay 1 is selected, the relay contact for Switch A or Switch B will open when Delay 1 expires. This contact will
remain open until the status changes from unoccupied to occupy again. The same operation goes for Delay 2.
The user has the option to select both Switch channels to operate off the same timer.
