ITEC*NET

  • Ethernet-based multi-channel PA system for alarming, evacuation, music and broadcasting
  • Simultaneous transmission of up to 64 digital audio channels in studio quality (48 kHz / 24 bit),
    with a constant latency period of 1.33 ms (digital)
  • Distributed audio system no „single point of failure“
  • Real-time configuration with ITEC-NET - NET-DESIGN:
    Allows system configuration changes during normal operation of the system.
  • Real-time audio transmission: Constant latency of 4.6 ms analog-in/analog-out
  • Up to 4000 devices can work simultaneously together in a network
  • Up to 16,000 output zones in one audio network
  • Optional 2 GB memory card for alarm texts and music files.
    Recording Capacity 256 files, total time about 3 hours!
  • Integrated real-time recorder for delayed announcements
  • Speaker impedance and line monitoring during program mode
  • AVC: automatic volume control
  • ITEC-NET application interface (TCP / IP) for connecting to security management systems
  • Remote maintenance, remote control, various interfaces for fire alarm systems
  • 24VDC power for supply using EN54-4-certified energy supply equipment.
  • System certified according to EN 54-16: EC conformity certificate no. 1293-CPR-0700

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 ITEC-NET 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, ITEC-NET 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 ITEC-NET we did our part to meet the manufacturer requirements for EN 54-16 certification, and in many areas we even exceeded them.

ITEC*NET

The combined Break-in/Break-out module in 19“ design, equipped with 4 analog audio inputs and outputs, 2 network ports and 24 VDC power supply. Other connection options: 2 serial ports (RS-232 and RS-485) for control tasks, 8 analog inputs, 8 digital inputs, 8 digital outputs, optional plug-in card for speaker monitoring (4 channels), integrated 2 GB Micro SD Card Flash memory card as a voice mail. Front-page display for the output of messages. Online/realtime system-configuration with free ITEC PC-software NET-DESIGN from every network accesspoint. Multiple access, realtime configuration of all system parameters
including audion-functionalities!

The SPIDER44 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, status display to indicate the key system statuses on the front.

The ITEC-NET 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.

Net-Design Configuration, Maintenance, Control, and Interface Software

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.
