The 4EVAC public address and voice alarm system is made up of two compatible and combinable ranges, the compact “all-in-one” C500 and the scalable IMPACT.



Evacuation and voice alarm system "all in one", with the simplicity of a stand-alone device and the benefits of network topology to link and expand the system.

Each C500 manages 6 audio streams that can be broadcast simultaneously on the 6 loudspeaker lines connected to the 100 W RMS power amplifiers.

For global paging, the C500s are networked, via a redundant loop, with 2 audio channels and one serial data channel (RS485).

o C500


Scalable evacuation and voice alarm system based on a minimum number of elements: the controller, the power units and the zone selectors.

The controller transfers two audio channels and data to a total of 16 power amplifiers.

The 2 x 500 W RMS class D power amplifiers include a battery charger and local input for music.

The selectors control six loudspeaker zones and distribute evacuation and alert announcements, live and music.

o C500
C500 and IMPACT are linkable and fully compatible through a global network of up to 254 nodes that enables the management of 1,400 loudspeaker lines.


Ease of assembly

C500 is designed to facilitate installation and configuration. Electronic components are easy to insert and remove, and a simple and effective wall bracket simplifies the placement of the cabinet, easy even for a single person. In addition, configuration software and error detection tools speed commissioning.
