 ANNAX Intercom Units

 

Train Intercom Unit – TIU

The TIU is used by train personnel to communicate with each other and to receive e.g. service calls from passenger communication units (PCU). The unit also allows making public announcements, which will be heard via the train’s service loudspeakers. The housing of the TIU can be customised to fit the specifications and dimensions of the train.

 

 

 

 

 

 

Passenger Communication Unit – PCU

The passenger communication unit allows passengers to communicate with train personnel. The operation status and connection status of the PCU is displayed via LEDs. The housing of the TIU can be customised to fit the specifications and dimensions of the train.


 

 

 

 

ANNAX Audio Technology

 

 

IP-Amplifier

The IP-Amplifier is an autonomous amplifier, which receives speech data via Ethernet and via UIC. The device consists of a standard rack with a width of 42 TE and a height if 3HE, an amplifier component (Type Ramp) and a power component (RP110, RP72 or RP36, depending on available voltage). The amplifier contains 4 independent amplifier circuits with 2 x 25 Watt and 2 x 3 Watt respectively. Loudspeakers can be connected via 100V method or via low-impedance connection. The IP-Amplifier can be delivered with or without an inbuilt transmitter.

Next to the four loudspeaker circuits, up to 3 microphones can be connected to the amplifier. An example for a possible application would be a measuring microphone to automatically regulate the sound level or a service microphone for the vehicle driver.

In addition the amplifier is equipped with two serial interfaces RS485, which can be used to connect matrix displays or a seat reservation system.
