Voice Alarm Control

and Indicating Equipment



COMPACT, Distributed VACIE

The COMPACT Networked VACIE solution is based on distributed boxed-amplifiers concept. This cutting-edge of digital audio-distribution technology, represents a variety of compact self-contained Wall-mounted Control and Indicating Voice-Alarm panels, creating a flexible and still simple to control distributed VACIE concept.


The COMPACT is a thoroughly voice evacuation ‘system-in-a–box’ concept which offers the simplicity of a stand-alone conventional system and the benefits of global Network topology.


The COMPACT drives 2 ‘live-stream’ audio channels and one serial data channel (RS485) over a redundant Global-Network-Loop into global zones and operates a 6-channel message players that send synchronized audio into the local zones. This way each COMPACT has the ability to generate 6 differents audio-streams playing into the local zones simultaneously.


Each COMPACT contains the necessary routing to serve up to 6 single zones of 6 x 100 W RMS with additional active back-up amplifier. With a maximum of 255 boxed-VACIE panels in a Global Network, each serving 6-zones, a single installation can reach over 1500 speaker lines, cumulated into multiple paging zones within an architecture of 256 priorities.


COMPACT is equipped with a wide range of pre- and post-processing software modules such as volume controllers, routing, mixing, switching and prioritizing. Processing components as; equalisers, limiters and delay-lines make COMPACT fit for the job.


The integrated local Message storage modules (WAV-format), with a total storage capacity of 16 audio files, can be distributed simultaneously over the 6 local output lines serving phased-evacuation. The status of the digital audio message storage and of the messages themselves are monitored.


All message-storage modules are synchronised between multiple COMPACT output lines for synchronized large area incident warning. 

4EVAC-Compact500-networked VACIE solution-Voice evacution system

Fully compliant: 


in order to ensure peace of mind for both the installer and end user, 4EVAC products are third party approved and certified to relevant European standards. 


4EVAC approvals go beyond the minimum requirements including EN54-16:2008, EN54-4:2006, EN54-17:2005 and EN50130-4:2011.

Network topology


Its redundant token ring network topology provides a communications platform for global incident warnings, control and information sharing that does not require any form of centralized processing.


Each COMPACT holds a copy of the global system settings on an exchangeable SD card and is able to continue working even in the event of total loss of communication.


This ensures unparalleled survivability compared to conventional systems that rely on a central control device. This highly reliable concept is copied through the whole range of dedicated field devices.​

  • Up to 255 nodes per system with ‘peer to peer’ system redundancy;

  • Max distance between nodes: 250 m (standard FTP CAT5e cable);

  • No practical limit to network wire length;

  • 200 kbit datastream;

  • Redundant ring technology;

  • 2 live anti-parallel audio streams.

  • Upstream priority channel;

  • Downstream back-up channel.



This shows a basic voice evacuation system configuration where the COMPACT fits perfectly! Equipped with 6 evacuation zones the wall-box is installed in the main entry area where it can be easily observed and controlled in case of an incident. The frontpanel controls are adequately accessible and the integrated firemens-microphone provides clear vocals into the evacuation zones.
