Product information "TSA-a/b"

The conversion of telephony to IP often involves purchasing a new ICT system. Although these modern systems are state-of-the-art and offer all sorts of modern features, you will not find a connection for the existing door phones anywhere. Here's the solution:

With the TSA-a/b door phone adapter, door terminals with an older 4-core interface or a 2-core connection in accordance with FTZ 123 D 12-0, which perhaps cannot be easily replaced for structural reasons, can be connected to the analogue port of a modern, VoIP-enabled ICT system. The existing door terminal, from Siedle, Ritto, Grothe or Auerswald/FONtevo for example, can be kept.

The TSA-a/b is suitable for use on all conventional ICT systems with analogue subscriber ports.

Technical Highlights:

  • Access of older door phone systems with up to 2 bell buttons to an analogue port of a modern ICT system
  • Inverter from 4-wire and FTZ 123 D 12-0 interface to analogue subscriber ports
  • Additional switching options via optional a/b Switching Modules
  • Power supply via bell transformer
  • Separate volume control for both speech channels, impedance adjustable
  • Built-in power amplifier for stations without an output amplifier
