The MRBD relay board has six relays, which are controlled by RCO's from the exchange or from a RIO unit. The MRBD must be powered by +24 VDC. The AlphaCom XE7 and XE20 comes with a 24VDC outlet for such purpose, but in the AlphaCom XE26 a Power Distribution Board PDB is required.
In the AlphaCom exchange it is recommended that all the RCOs be connected to the same ASLT board(s) in order to simplify cabling.
The MRBD board is supplied in an installation box that can be fastened onto the mounting rail on the connection field of the AlphaCom exchange, or mounted on the wall in any suitable position.

Connectors and Switches
The jumpers S1-S6 determine if the RCO should be activated by a high or low level. High level is used in AlphaCom system, while low level was used in the previous TouchLine generation of intercom system.
Connections
AlphaCom XE7
In the XE7 the cable is connected to the 8-pin pinheader labeled RCO 1-6 or RCO 7-12.
- An ASLT board in board position 1 is required to operate RCO 1 - 6.
- An ASLT board in board position 2 is required to operate RCO 7 - 12.
AlphaCom XE20/26
In an AlphaCom XE26 the 24VDC power is provided by the Power Distribution Board PDB.
