Additional Documentation
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.
