• Backup concept conforming to standard, with option to switch to redundant amplifier output stage
• System certified according to EN 54-16

In the future, safety PA systems are going to replace the classic siren alarm. The reason for this is that these days only few people react to siren alarms, and alarms, evacuation signals, alarm cancellations, etc. can no longer be differentiated.
In contrast, using clear voice instructions a building can be very efficiently evacuated in the event of fire or an emergency. The larger a building, and the more people there are in this building, the more important it is to install a modern safety PA system.

Our ITECNET Development team has considered these requirements from the very beginning. Complete system monitoring, surveillance of emergency microphones, amplifiers, speech memories, speaker lines, and of the energy supply. Thanks to the decentralised concept, ITECNET also allows for fully redundant systems at the highest safety level, and there is no single point of failure. A multitude of standards regulate planning, installation, operation and production of so-called safety PA systems. With ITECNET we did our part to meet the manufacturer requirements for EN 54-16 certification, and in many areas we even exceeded them.

The Dante Bridge in 19“/1U design is equipped with a Dante board from Audinate to transfer 8 digital Dante channels each. 2 network connections for the Dante module and 4 network connections for ITECNET enable the two networks to be separated. Communication takes place internally via a digital audio interface.

Other connection options: 1 serial port (RS232 / RS485) for control tasks,
8 analog inputs, 8 digital inputs, integrated 2 GB Micro SD Card Flash memory card as a voice mail. Online/realtime system-configuration with free ITEC PC-software NETDESIGN from every network accesspoint. Multiple access, realtime configuration of all system parameters including audion-functionalities!

The Dante Bridge has an integrated and monitored voice alarm text memory with a recording capacity of up to 3 hours. Alarm announcements are automatically controlled by the fire alarm system or can also be triggered manually.

Other features: Automatic volume control (AVC), DSP functionality for all outputs and inputs, compressor limiter, delay of up to 24.5 seconds (acoustically corresponds to 8 km delay time), TCP/IP interface, serial interface for control
systems, 8x8 audio matrix, Automixer, Ethernet switch, up to 192kHz/24Bit, Backup outputs, FFT.

The ITECNET components are networked via our standardised and certified network switch in accordance with Ethernet standard IEEE802.3u. Up to 4000 devices can be linked in a LAN.

ITEC NET-DESIGN is a Windows-based application for configuring and monitoring the entire ITEC-NET network. Included is a TCP/IP interface (ITEC-NET API) allowing a direct link to other control systems, such as media control or security management systems. In addition NET-DESIGN offers the possibility to update the DSP- and control software from any point of the network. The huge number of monitoring and logging capabilities ensures a safe operation within this large audio and data distribution system.
