CommLink TR6442i Fiber Optic Intercom Link Power Options
The CommLink TR6442i Fiber Optic Intercom Link Fiber Optic Intercom Link is powered
through an attached external power supply or from power received from the Two-Wire
intercom connection.
The following table shows how each CommLink TR6442i Fiber Optic Intercom Link unit can
be powered:
* 30 Volts is output from the CommLink TR6442i Fiber Optic Intercom Link unit when it has
12V power applied. When no 12V power is applied (2W Power switch is on EXT), the
CommLink TR6442i Fiber Optic Intercom Link unit derives power from the intercom
connection and all Belt-Packs derive power from the Intercom system or from internal
power sources.
When powered by the 12 Volt power supply, the CommLink TR6442i Fiber Optic Intercom
Link will power five intercom belt packs (10 total on the system) or two remote matrix
stations per channel. If the system has self-powered belt packs attached (30V), and the
external 12 Volt power supply is also attached, the 12 Volt supply takes priority in powering
the CommLink TR6442i Fiber Optic Intercom Link.
