| New IF2000 Public Address & Intercom with Analog Intercom Stations |
Building Block Typical Diagram
Features:
• Full integration with Public Address and Telephone Systems.
• Public Address / Intercom stations fitted with up to 8 lines with visual indication which, depending on project requirements, can be configured individually as page line, party line or direct call to control room.
• Extended intercom operation (omnibus page/party, group calls and conference calls), with up to five simultaneous conversations on the same party line.
• Paging zone calls (including single zones, any combination of zones and all zones).
• Broadcast with priority of pre-recorded messages, alarm tones and special signals (such as start or end of work, etc.), including single zones, any combination of zones and all zones.
• Broadcast of pre-recorded messages and music through radios, CD readers and MP3 players.
• Public Address / Intercom stations with built-in high efficiency 25W class D power amplifier for connection of up two 8Ohms loudspeakers, and fitted with time-out function for disconnection of the line after a pre-set time.
• Distributed amplification (integrative to the power amplifiers installed inside the Public Address/Intercom stations) performed through the use of self-amplified loudspeakers (rated power: 15W or 25W; power supply: 24-48Vdc, fitted with built-in power amplifier, continuous volume control from 0W to the max rated power and with ALC (Automatic Level Control) of the output power according to the variation of the ambient noise level).
• Equipment power supply from 24Vdc to 48Vdc through high efficiency 230Vac/24-48Vdc power supply unit with or without back batteries.
• Main Public Address / Intercom stations (access panels) fitted with handset and dedicated push buttons with visual indication for direct activations.
• System architecture allowing, in case of fault of a field device (Public Address / Intercom stations, speakers and beacons), the complete operation of all other field devices even in case of multiple fault events.
• Digital noise cancelling and noise reduction algorithms, so as to allow the intercom user to communicate in hands-free and full-duplex mode even if the ambient noise level is more than 100dB.
• Interfacing with plant Telephone System, plant Radio System and with existing Public Address and Intercom Systems.
