Page & Talk Systems with VoIP Intercom Stations and ReteMatic™ Technology


Main Features
• Fully integrated Public Address / Intercom / Telephone System.
• Distributed amplification performed through the IP-ADI interface fitted with ReteMatic™ technology, providing a 30W Class D amplifier capable to support up to two standard (non-amplified) 8Ohm loudspeakers, a visual beacon and 4 inputs for an external alarm keyboard or other alarm contacts.
• IP-ADI interface in water-proof and explosion-proof versions, providing full diagnostics over the connected devices.
• Highligts of ReteMatic™ networking are:
- carries both power (90-240Vac) and data over standard non-polarized power cables;
- any network topology supported (bus, chain, star, even mixed);
- composed by an head-end, interfaced to a standard Ethernet LAN, and up to 15 devices for (max distance approx. 500 meters from the head-end);
- many ReteMatic™ networks may be interconnected by means of a standard Ethernet switch.

• Real-time monitoring & fault reporting.
• 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 and/or alarm tones (including single zones, any combination of zones and all zones).
• Public Address / Intercom VoIP stations fitted with double full-duplex conversation mode: with handset or hands-free (without handset).
• Main Public Address / Intercom stations (access panels) VoIP based, fitted with handset and keypad. If required, also equipped with gooseneck microphone and additional 40 buttons (up to 48 in total) keypad for direct activations.
• Very cheap and cost-effective cables network, i.e. only 2 wires (plus ground wire if needed) to interconnect all IP-ADI interfaces and relevant head-end.
• 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.
• Intercom systems fitted with some special requirements for Exploration Drilling Rigs (frequently moved), i.e. quick to install and dismount, very easy to connect and easy monitoring of system health.

Main Applications
Oil & Gas (Exploration Drilling Rigs), Petrochemical, Power, Steel, Heavy and Light Industries, Mobility (Temporary Construction Sites).

Main Options
• Base station for wireless communication by means of DECT terminals and headsets.
• Multi-functional pillars to include intercom station, amplifier, loudspeakers, visual beacon, alarm keyboard and an integrated junction box in a single, easy to move unit.
• Interfacing with other existing Public Address & Intercom Systems.
• Telephone interface with the plant Telephone System.
• Radio interface with the plant Radio System.
• Broadcast of pre-recorded messages and music through radios, CD readers and MP3 players.
• Dual feeders power supply managing.
• Central cabinets fitted with surge protectors.
• Central cabinets fitted with antiseismic kit.
• Power supply unit in redundant configuration “1+1”.
