Our Expertises

A sound system is a key asset for operating and securing ERPs and ERWs. It covers technical, commercial and regulation issues all at the same time.
In the event of danger or an incident, it helps evacuation, playing a crucial role in guiding people and keeping them safe; this refers to a Safety Sound System (SSS).

The SSS combines two functions:
– broadcasting evacuation messages, aiming to convey everyone inside to safety, outside the buildings,
– broadcasting reassuring messages, to encourage people and convey information.

NF and EN54-certified, the DEF Network SSS offer is linked to the FSS range, guaranteeing a suitable response to needs and evacuation obligations.
The DEF Network also offers PPSS solutions, through customised messages.
