EN 54-certified PA solutions have to convince with excellent speech intelligibility as well as comply with the high requirements of European standards. Voice alarm systems (VAS), for example, ensure the fastest possible evacuation from a danger zone.
The speakers EDL-165AB/WS, ESP-62AB/WS and RL-1ENABDS which are used in the sales areas and adjoining rooms feature two independent transformers each, thus applying A/B line cabling in accordance with EN 60849. This means that a fault in the amplifier or on a transmission path does not automatically lead to a failure of the voice alarm system in an alarm section. Each A/B speaker is driven by 2 x PA power amplifier SINUS-220 (2 x 240 W each).
As the central unit, the MEVAC-4 is used to transmit microphone announcements, stored evacuation messages (MP3 format) or background music. The controller ensures all required and necessary monitoring functions for up to 4 speaker lines and features connections for system microphone station MEVAC-4PTT and up to 2 x fireman’s microphone MEVAC-1FH (hand-held microphone).
The MAESTRO-1 can also be used to make announcements from any telephone connected to the telephone system. Apart from emergencies, the VAS is also used for other purposes (e.g. background music, advertising, staff announcements). A digital stereo tuner FM-102DAB is used as a music source.
