4EVAC Compact - voice alarm and indicating equipment

The COMPACT Networked VACIE solution is based on the 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 thorough voice evacuation ‘system-in-a–box’ concept that 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 6-channel message players that send synchronized audio into the local zones. This way each COMPACT has the ability to generate 6 different 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 an additional active backup 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 such as; equalizers, 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 synchronized between multiple COMPACT output lines for synchronized large-area incident warnings. 

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 a 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.​​
