The analog subsystem module ACM-IP2.1 converts the digital communication interface to analog and vice versa. This allows you to connect analog subscribers, including simplex intercoms, amplifiers, analog low-frequency lines, discrete lines for control of terminal devices of simplex communication, warning and call signaling, analog communication systems, incl. legacy or receive commands from automation and alarm systems to trigger a PA announcement.

ACM-IP2.1 contains embedded software and configuration data stored in RОM, which allows it to communicate with other digital communication system users directly, handle priority connections and manage communication and indication modes. An IP-network built using standard network equipment is used to facilitate communication.

ACM-IP2.1 can be used in the metals, chemical, mining, oil and gas, metal processing and wood processing industries, in facilities of the Transportation Ministry, Emergencies Ministry, Interior Ministry and Defense Ministry.

  • Simplex communication between analogue and digital subscriber devices via «Armtel-IP» and SIP protocols;
  • Construction of loud-speaking zonal PA/GA system (up to eight zones);
  • Handle priority connections via «Armtel-IP» and SIP protocols;
  • Recording voice messages to the device memory (WAV format, linear encoding 16 bit 16 kHz);
  • Storing messages with a total duration of up to 1500 minutes;
  • Playback of pre-recorded voice messages;
  • Connection of alarm and automation systems through «dry contact»
  • Automatic playback of pre-recorded voice messages by commands from alarm systems;
  • Broadcasting of individual and group announcements;
  • Enabling control lines on command from other subscriber devices of the system;
  • Control of external 48VDC relay;
  • Remote administration and upload of voice messages.
