Intercom with Analog Intercom Stations |
Building Block Typical Diagram

Features:
• Full integration with Public Address and Telephone Systems.
• Extended intercom operation (omnibus page/party, selective point-to-point, group calls and conference calls), with virtually unlimited number of simultaneous conversations.
• Paging zone calls (including single zones, any combination of zones and all zones).
• Alarm tones and/or prerecorded messages zone broadcasts (including single zones, any combination of zones and all zones).
• Broadcast of pre-recorded messages and music through radios, CD readers and MP3 players.
• Double functionality of Public Address / Intercom stations and plant telephone sets, i.e. Public Address / Intercom stations working also as telephone sets connected to the plant PABX, as well as plant telephone sets working also as Public Address / Intercom stations connected to the Public Address / Intercom System. In case of failure of Public Address / Intercom System or plant PABX, the telephone or Public Address / Intercom functionality is any case guaranteed.
• Public Address / Intercom stations fitted with double full-duplex conversation mode: with handset or hands-free (without handset).
• Possibility to utilize as Public Address / Intercom stations any type of Fitre analog telephone sets (indoor, weatherproof and explosion-proof, including cordless/DECT).

If required, also equipped with gooseneck microphone and additional 40 buttons (up to 48 in total) keypad for direct activations. Max allowed distance of access panels from LAN switch is 250 meters (instead of 100 meters as per usual standard).
• Very cheap and cost-effective cables network using standard cables (one standard telephone pair for each Public Address / Intercom station).
• System architecture allowing, in case of fault of a field device, the complete operation of all other field devices even in case of multiple fault events.
• Public Address / Intercom stations star connected to the central unit of the system, with a maximum allowed di-stance up to 3 kilometers.
• Interfacing with plant Telephone System, plant Radio System and with existing Public Address and Intercom Systems.
