Plena Voice Alarm SystemApplication Note: Swimming pools

Introduction

The Plena Voice Alarm System is the ideal sound

management solution or swimming pools. A voice alarm

system or a swimming pool requires voice alarm

unctionality as well as public address unctionality or

regular announcements and (optional) background

music (BGM). To ensure that all visitors in the relatively

noisy pool area hear emergency messages, the power

output or that zone is relatively high. Other areas,

such as the changing rooms and oces, have lower

power requirements. Swimming pools and other indoor

sports and recreational acilities are typical examples o

smaller applications with ew zones. The main priorities

are excellent speech intelligibility and compliance with

EN 54, ISO 7240 and EN 60849 standards, although

music in diferent areas is optional. All necessary

requirements and more are met by the Plena system.

Solution for a 6-zone system

The Plena Voice Alarm System Controller handles

routing to up to 6 zones, so no additional routers are

required. The oce/reception is equipped with a call

station plus keypad or individually addressing zones,

while a remans panel (with overall priority) is built in

by the emergency exit. The Plena Voice Alarm System is

a two-channel system, so BGM can still be provided in

zones not receiving a call.

The Plena Voice Alarm System is designed or

plug-and-play installation, and is easily congured

using DIP switches or sotware or more advanced

conguration. Once congured, the PC is disconnected.

System interconnections are made using standard RJ45

connectors and CAT5 cabling. Up to 255 spoken

evacuation messages can be stored. Messages can also

be merged to allow more exible use o pre-recorded

messages.
