Public Address & Voice Alarm
From emergency announcements to background music, one system.
Zone-based public address, emergency announcements and background music on one infrastructure. Speaker placement follows the acoustics of the space; fire system integration is tested at commissioning.
Scope
What does the system do when the signal arrives?
- Zone management
- Emergency announcements
- Ceiling speakers
- Fire integration
- Background music

What is in the quote?
Written line by line; work that is not on the drawing is not in the quote.
- 01 Ceiling and wall speakers
- 02 Zone management
- 03 Emergency announcements and fire integration
- 04 Microphone and paging console
- 05 Background music and scheduling
Who it is for
- Crowded, zoned buildings such as malls, hotels and hospitals
- Factories needing shift and emergency announcements on the floor
- Sports halls, arenas and event venues
- Office towers wanting background music in common areas
When it is needed
- When fire regulations require a voice alarm system
- When announcements are inaudible in some zones and too loud in others
- When different zones need different announcements
- When the existing system does not talk to the fire panel
How it proceeds
How does the work proceed?
- 01
Acoustic and zone plan
Speaker type and count follow ceiling height and surfaces; zones follow the way the building is used.
- 02
Cabling and mounting
Speaker lines are pulled per zone; ceiling and wall speakers are installed.
- 03
Paging console and integration
Microphone console, pre-recorded emergency messages and fire panel integration are set up.
- 04
Sound test
Intelligibility and level are tested in every zone; scheduling and background music are configured.
Note from the field
In high-ceiling venues such as arenas, speaker aiming matters more than speaker power. A few speakers at the right angle give clearer announcements than many at the wrong one.

Most asked during site surveys
Can voice alarm and ordinary PA be one system?
Yes, one infrastructure can carry background music, paging and emergency announcements; emergency messages are always programmed to override everything else.
What is a zone and why does it matter?
A zone is the area that receives the same announcement at the same time. Separate announcements for the car park and the canteen only work if zones are defined correctly from the start.
Announcements are unintelligible. What can be done?
Usually a placement or reverberation problem. Measurement finds the affected zone; speaker aiming, count or type is changed.
Are pre-recorded announcements possible?
Yes. Evacuation, closing and warning messages are recorded and played automatically on a fire alarm or at set times.
On every project
The same team from survey to maintenance.
- 01
Survey
We walk the site and see the existing infrastructure and the need in person. The report and preliminary budget rest on this visit.
- 02
Design
Route, equipment list, cabinet layout and schematic. Whatever the quote covers is on the drawing.
- 03
Installation
Mounting, cabling, termination and commissioning. Test reports are part of the handover file.
- 04
Maintenance
Periodic checks, fault response and capacity growth. We are fast because we know the system we built.
