Application: Shopping mall

2.4.1

Introduction

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 IEC60849 standard
(and its national equivalents)
2.4.2

Requirements

In addition to mandatory voice alarm functionality for
evacuating the public and shop personnel, an
Econtroller 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, the
volume override of each individual shop is engaged.
Additional public address functionality for making
general public announcements is an optional
requirement.
table 2.7: Summary of requirements
Requirements
54 zones (typically up to 60 zones)
Speech intelligibility is the main priority

Call station in security control room
Additional public address functionality
(nonemergency)
BGM in public areas
BGM music with local override in shops
2.4.3

Solution

A Plena voice alarm 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 booster amplifiers
are incorporated to provide additional power, two-
channel operation and for use as a spare amplifier.
