Heard clearly.
Everywhere it matters.

Public address and background audio zoned to the project — and ready to carry an evacuation message the moment the fire panel asks for it.

Overview

Background music by day. Voice evacuation when it counts.

Most people experience a sound system as background music in a lobby or a page for a colleague. The same loudspeakers, amplifiers and zoning have a second job: when a fire panel goes into alarm, they must stop the music and deliver a clear, intelligible message to the people who need to move.

That dual role shapes the design. Zones follow the building's evacuation plan. Loudspeakers are placed for intelligibility, not just coverage. Amplifiers and lines are monitored, so a fault is known before it is needed.

We design sound systems as part of the wider security and life-safety picture: tied to the fire alarm, controllable from the command room and, where the project wants it, carrying the hotel's playlist as well as its safety.

What we deliver

Capabilities, not a catalogue.

  • 01

    Zoned public address

    Announcements to the zones that need them, and only those.

  • 02

    Voice evacuation

    Phased, pre-recorded and live messages on the fire panel's command.

  • 03

    Background music

    Music sources routed to lobbies, restaurants and pools.

  • 04

    Paging & call stations

    Microphone stations for reception, security and management.

  • 05

    Scheduled announcements

    Prayer times, opening hours and safety notices.

  • 06

    Line & amplifier supervision

    Faults reported to the panel and the command room.

  • 07

    Networked audio

    IP-based distribution across large sites and multiple buildings.

  • 08

    Priority & override

    The alarm always wins over music and pages.

  • 09

    Ambient noise sensing

    Volume follows the noise in the room.

  • 10

    Integration-ready

    Fire alarm, command room, BMS and the hotel's systems.

Typologies

The building blocks we design with.

Every project is composed from a small number of well-understood parts. These are the ones that matter for this discipline.

Loudspeakers

  • Ceiling loudspeakers

    The standard for corridors, offices and lobbies.

  • Wall & cabinet loudspeakers

    Rooms with no ceiling access or higher output needs.

  • Horn loudspeakers

    Car parks, plant rooms and outdoors.

  • Column & line-array loudspeakers

    Long rooms, atria and prayer halls.

  • Sound projectors

    Directional coverage for corridors and outdoors.

  • Fire-rated loudspeakers

    For voice evacuation applications.

Signal & control

  • PA & voice alarm controllers

    The routing brain, with priority and supervision.

  • Amplifiers

    100 V line amplifiers sized to each zone.

  • Call stations

    Paging microphones with zone selection.

  • Message players

    Pre-recorded evacuation and information messages.

  • Network audio interfaces

    Audio over IP between buildings.

  • Audio sources

    Music, radio and streaming inputs.

Infrastructure

  • Fire-rated cabling

    Keeps voice alarm working during an event.

  • Battery back-up

    The system stays on when power does not.

  • Racks & monitoring

    Equipment rooms with supervision.

How it works

From the edge to the operator.

Priority is engineered, not hoped for: an alarm message from the fire panel overrides every other source, in every zone it addresses.

  1. 01

    Source

    Microphone, message player or music

  2. 02

    Controller

    Routes by priority: alarm, page, music

  3. 03

    Amplifier

    Powers each zone's line

  4. 04

    Loudspeaker zones

    Areas that follow the evacuation plan

  5. 05

    Supervision

    Line and amplifier faults reported

  6. 06

    Fire panel & command room

    Alarm command in; status out

Works as one system

10+ solutions, designed as one system.

Safe & Sound carries every discipline, so this system is designed from day one to talk to the others on the project.

  • Fire alarm

    The panel triggers phased evacuation messages zone by zone, and receives the PA's fault states.

  • Command rooms

    Live announcements and message triggering from the desk; system status on the platform.

  • Intercom

    Emergency help points and paging on the same audio network where appropriate.

  • CCTV

    Announcements can be triggered from video events — a warning to a person in a restricted area.

  • Smart home & BMS

    Music scenes and schedules follow the building's mode.

A typical sequence

Evacuating a hotel floor

  1. 01

    The fire panel confirms an alarm on floor four.

  2. 02

    The PA stops the music on that floor and plays the alert message; adjacent floors receive the standby message.

  3. 03

    Reception uses the call station to give live instructions to the lobby.

  4. 04

    The command room sees message status and any loudspeaker line fault in real time.

Applications

Where it earns its place.

Sound systems matter most in buildings full of people who do not know the layout: hotels and resorts, malls and retail, universities, hospitals, factories with noisy floors, Nile cruise vessels and transport infrastructure.

  • Hotels & resorts
  • Retail & malls
  • Corporate buildings
  • Schools & universities
  • Healthcare
  • Factories & industrial
  • Nile cruises
  • Infrastructure
Technologies we work with

Selected manufacturers.

A deliberately narrow stack, supplied through authorised channels only. The final selection is made per project, against the specification and the budget.

  • Bosch
  • Honeywell
  • Axis Communications
  • Hikvision

For public address and voice alarm we work with Bosch and Honeywell systems, and with Axis and Hikvision network audio where an IP loudspeaker approach suits the site.

Our approach

One partner. Every step.

01

Design

Zone plan aligned with the evacuation strategy, loudspeaker layout and tapping for intelligibility, amplifier and controller sizing, message scripts, fire-alarm interface design and cabling specification.

02

Supply

Loudspeakers, amplifiers, controllers and call stations from authorised channels, with messages recorded and approved before commissioning.

03

Install & integrate

Loudspeakers and cabling installed with the ceiling and electrical contractors, zones balanced and intelligibility checked, the fire interface proven, and operators trained on paging and messages.

04

Document

Zone schedule, as-built drawings, message library, interface matrix with the fire panel, and a lifecycle plan for amplifiers and batteries.

05

Maintain

Scheduled listening tests in every zone, supervision and battery checks, message and schedule updates, and a report to the client.

Maintenance

Installed today.
Supported tomorrow.
Trusted for years.

We stay involved after handover. Every system leaves us with a maintenance path, a named point of contact and a report you can read.

A loudspeaker that has failed makes no noise about it. Supervision reports the line, but only a person can confirm the words are clear in the room.

See the three maintenance tiers
  • Preventive visits: listening tests in every zone
  • Line, amplifier and battery supervision checks
  • Fire-alarm interface re-testing after changes
  • Message library and schedule updates
  • Controller and network audio firmware updates
  • Fault response under the contracted tier
  • Replacement planning for amplifiers, batteries and loudspeakers
