Contact closure interface

The FSR ML-116-INT is a Contact closure interface that can output 32 mix switch or head table switch outputs. If both mix and head table information is required then then additional units can be added. The serial data from the ML-116 system would just loop thru each unit. The ML-116-INT unit has an indicator LED for each corresponding wire terminal. These terminals denote either room combinations or head table positions. The inclusion of a LED for each terminal provides a rapid and accurate way to determine the operational status of both the ML-116 and the LUTRON lighting equipment.

The ML-116-INT is supplied with a UL listed wall mounted transformer to power the unit. A 3-year warranty is included.

A drawing of the ballrooms/meeting rooms is provided with each system. This drawing indicates the room mix switches and head table locations (via a numbering system) as they correspond to the appropriate terminal positions on the ML-116-INT. If multiple ML-116-INT units are required for either the mix or head table functions then the map drawing would indicate that and provide for it in the numbering system.

The actual unit is 7.5" long by 6" wide by 2" high, excluding the mounting ears each of the four of which are 1.5" wide by 0.5" long. The unit weighs approximately 3 lbs. It is located in the lighting equipment bay, not in the audio equipment area. It does not matter if the ML-116-INT is powered before or after the ML-116 Audio Control Unit. The ACU periodically scans for all line devices.
