| Emergency Telephone Systems with VoIP Emergency Call Points and Self-Powered Emergency Telephones |
Main Features
• Fully integrated Emergency Telephone & Self-Powered System.
• Centralized ASTRO Call Manager provided in back-up configuration (one in the Main Control Center and the other one in Back-Up Control Center).
• Real-time monitoring & fault reporting.
• Remote configuration and diagnostics from the Control Center through a suitable PC workstation with relevant software.
• ECP (Emergency Call Points) usually installed in the railway/subway stations (including lifts) consisting of VoIP emergency telephones fitted with one or two call buttons (typically: “SOS” for emergency calls and “INFO” for information calls).
• Emergency telephones usually installed in the tunnels consisting of self-powered telephones with call generator connected in parallel on the same two wires cable and not requiring any kind of power supply.
• Lifts Emergency Call Points fitted with one “SOS” call button for direct communication with the relevant Control Center digital operator console.
• Station Emergency Call Points fitted with one “SOS” call button for direct communication with the relevant Control Center digital operator console plus one “INFO” call button for direct communication with the relevant station digital operator console.
• In case of normal system operation, all emergency calls coming from the self-powered emergency telephones are addressed (through the station IP-MAG unit and the LAN network) to the relevant Control Center digital operator console.
• In case of IP-MAG unit and/or LAN network fault as well as in case of station complete power supply loss, all emergency calls coming from the self-powered emergency telephones are automatically addressed to the station emergency self-powered operator console and in parallel also to the extreme emergency self-powered operator console of the next station, so as to guarantee the full redundancy of the station emergency self-powered operator console.
• Emergency Call Points connected to the LAN network through standard PoE with CAT.6 cable.
• Maximum distance between two self-powered emergency telephones (or operator consoles) of 6-8 kilometers depending on the size of the copper cable (typically, it is recommended a twisted pair 2 x 1.5 mm²).
• 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.
• Emergency Call Points fitted with 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.
Main Applications
Mobility (Metros, Railways, Highways, Roads and Tunnels).
Main Options
• ASTRO Call Manager in redundant configuration “1+1” in each Control Center cabinet.
• SIP trunking Wi-Fi interface with the on-board intercom system.
• ECP (Emergency Call Points) equipped with front window fitted with a suitable vandal-proof glass to protect the integrated built-in CCTV camera and relevant fixing mechanical support.
