Sound systems for emergency purposes

The broadcasting of messages and audible signals increases efficiency in emergency situations.
Keeping these systems available in the event of a power failure is vital. 

In case of danger, audio systems are used to emit an alarm via sirens, pre-recorded messages or voice announcements.
These signals alert and inform people in a building and, when necessary, encourage them to evacuate.
To ensure their operation at all times, the sound system equipment EN 54-16
must include a safety power supply certified according to EN 54-4.
