Audio control device

For door communication systems with audio components.

The audio control device is intended for door communication systems in which only audio components are supplied. It supports up to 70 devices (e.g. 1 built-in speaker, 5 add-on modules for built-in speakers, 68 surface-mounted home stations). In addition, the device features a door opener contact, which can be programmed using the buttons on the device.

Door openers with 8 to 12 V AC operating voltage can be connected directly to the control device's relay contact. Connecting other door openers is possible using an additional power supply. The electronic self-resetting overload protection is activated if the device is overloaded, e.g. if the bus lines are short-circuited due to an installation error or if too many bus participants have been connected.

Product features

  • Supply of the reverse-polarity and short-circuit-proof 2-wire bus LED status displays for operation, overload, system programming and door opener programming
  • 12 V AC output (1-10 s) to supply power to a standard door opener (max. current consumption 1.6 A/ED 25%)
  • Permanent 12 V AC output to supply power to the TC gateway
  • Relay output for switching a door opener with its own power supply
  • Door opener switching time infinitely adjustable from 1 to 10 seconds
  • Enables door communication systems with up to 70 devices to be set up (e.g. 1 built-in speaker, 5 add-on modules for built-in speakers, 68 surface-mounted home stations with hands-free feature)
