Shopping mall

Shopping malls are typical example of applications with a large number of zones with varying
output power requirements per zone. The priorities are speech intelligibility and compliance
with IEC 60849 standard (and its national equivalents). In addition to mandatory voice alarm
functionality for evacuating the public and shop personnel, an EVAC system for shopping
centers can have BGM for the public areas. It should be possible to individually call each shop
or store. During emergency messages, each shop's BGM volume control is automatically
overridden. Additional public address functionality for making general public announcements
is an optional requirement.

Solution for a 54-zone system
A Plena Voice Alarm System Controller handles routing to 6 zones, the remaining 48 zones
require eight 6‑zone routers. The security control room is equipped with a remote control
panel and call station plus keypads for individually addressing zones and BGM for the public
areas, while the controller unit and routers are located in a fire-resistant cabinet or basement.
Fireman's panel (with overall priority) is built-in close to the main entrance or emergency exit
(subject to relevant local regulations). The Plena Voice Alarm System is a two-channel system,
so BGM can still be provided in zones not receiving a call.
Power requirements
Each zone will have varying power requirements, ranging from small shops with a single
loudspeaker to department stores with several floors and more loudspeakers. Parking garages
and open-air walkways will require weatherproof sound projectors or horn loudspeakers. To
facilitate phased evacuation from different levels of the shopping center, public areas are
divided into zones. Additional Plena Power Amplifiers are incorporated to provide additional
power, two-channel operation and for use as a spare amplifier.
