ACM allows to connect to the communication system various analogue equipment, amplifiers, analogue lowfrequency lines and discrete control lines of simplex communication, signaling and alert devices, to provide interaction with automation and alarm devices. Analogue subsystems module is mounted in telecom cabinets or racks in the hardware, control rooms or office premises.

  • Connection to the system via the Uk0 digital interface;
  • Connection of an PA amplifier with selection of loudspeaker lines (up to 8 zones);
  • Connection of signaling and automation devices via relay modules;
  • Automatic playback of pre-recorded messages by commands from external emergency systems connected via «dry contact»;
  • Activation and control of the ACM module by any subscriber of the system;
  • Communication with VHS subscribers through the FM-radio base station.
