TCAS Connections

TCAS substation - Rear side

This article describes connection details of the analog intercoms TCAS-1, TCAS-2 and TCAS-3.

The Turbine analog station has an RJ-45 port and 6 external connectors.

Power	Draws power from AlphaCom signal line
RJ-45 port	AlphaCom connection
A, B, C, D wires	AlphaCom connection when RJ-45 port is not used

Note! Use cables crimped with ferrules for terminal block connectors

To set up the analog station as an intercom:

1. Connect the RJ-45 port on the station to the AlphaCom exchange

2. Register the station in the AlphaCom exchange

Wiring

The cabling from the AlphaCom server to the intercom station is star wiring. Two twisted pairs of wires are required. The maximum distance depends on the cable diameter:

• 0.5 mm wires: 1.4 km
• 0.6 mm wires: 2.0 km
• 0.9 mm wires: 4.0 km

The station line is connected by means of an RJ45 connector, or optional by using the plugable screw connector.

The station cable is not a 1:1 cable!

For details on connection at the AlphaCom server side, see ASLT - AlphaCom Subscriber Line Board

Second Call Key

The station is prepared for a future second call key (DAK2).

This second call key can be found on the print if wanted and utilized with an external call button.

• A second external call key must be connected between the A-wire and the lower leg on D6 (highlighted in the image above).
