Professional pa & voice alarm systems across Dunstable

Dunstable sits at the crossroads of the A5 and A505, making it a key commercial hub in South Bedfordshire. We serve businesses across Dunstable town centre, Houghton Regis, Toddington, and the surrounding villages, providing fast response times from our base in nearby Luton.

Dunstable's industrial profile is built around Woodside Industrial Estate and the A5/A505 logistics corridor, with significant construction-site activity tied to ongoing housing growth in Houghton Regis. Many of our Dunstable jobs are temporary CCTV towers and rapid-deploy alarm systems for active build sites.

For pa & voice alarm systems in Dunstable, we tailor the specification around the building, the people using it and the local risk profile rather than publishing a generic package. We also account for local compliance pressures in Bedfordshire, including central Bedfordshire Council requires construction-site security risk assessments for sites over a defined value threshold, and insurers underwriting builders' all-risks policies typically demand NSI Gold-monitored systems.

Frequently asked questions about pa & voice alarm systems in Dunstable

What is a PAVA system in Dunstable?
PAVA stands for Public Address and Voice Alarm. It's a single loudspeaker system that does two jobs: day to day it delivers announcements, paging and background music (public address), and in a fire it delivers clear, pre-recorded spoken evacuation instructions (voice alarm). Combining them means one intelligible speaker network instead of two, with fire messages always overriding everything else. The final specification for a Dunstable premises is always confirmed on site — how the building is constructed, occupied and insured can all change what we recommend.
Why use voice evacuation instead of just a fire bell in Dunstable?
Research and real evacuations consistently show people respond faster and with less confusion to a clear spoken instruction than to a bell or tone, which they may ignore or misread. Voice alarm also allows phased and zoned evacuation — telling one area to leave while another stands by — which a bell cannot do. For public, complex or high-occupancy buildings, a voice alarm is often required by the fire strategy.
What standards do voice alarm systems have to meet in Dunstable?
Voice alarm systems are designed and installed to BS 5839-8, using control equipment certified to EN 54-16 and loudspeakers to EN 54-24. A key requirement is speech intelligibility, measured by the Speech Transmission Index (STI) — the system must not just be loud, but clearly understandable. We design for and commission against these standards.
What is speech intelligibility (STI) and why does it matter in Dunstable?
Speech intelligibility is a measure of how clearly a spoken message can be understood in a space, expressed as a Speech Transmission Index score. A voice alarm that is loud but echoey or muffled fails its purpose because occupants can't make out the instruction. We design speaker positions to achieve the required STI and measure it at commissioning, so the evacuation message is actually intelligible where people are.
Can the same system be used for announcements and music in Dunstable?
Yes — that's the advantage of a combined PAVA system. The same speakers deliver background music, live paging and general announcements during normal use, and automatically switch to override every zone with the fire evacuation message the instant the fire alarm activates. You get everyday value from the system while it stays ready for its life-safety role.
How does the voice alarm connect to the fire alarm in Dunstable?
The voice alarm is interfaced to the fire alarm control panel so that a fire signal automatically triggers the correct pre-recorded messages in the correct zones — evacuate, alert or stand-by — without anyone needing to act. Emergency microphones also let responders make live announcements that override the recordings. We design, install and commission this interface as part of every voice alarm project.
Which parts of Dunstable do you work in?
All of them — including Houghton Regis, Toddington, Caddington and every LU5, LU6 postcode. Dunstable sits well inside our core Bedfordshire coverage area, so there's no call-out premium for any part of town.
What's your typical response time for Dunstable?
Enquiries are answered within one working day, and with Dunstable only about 15 minutes from base we can often attend at short notice — including urgent faults on existing systems.
Do you offer ongoing maintenance in Dunstable?
Yes. Most Dunstable clients put the systems we install on a servicing contract afterwards — it keeps the certification current and means small faults get caught before they turn into call-outs.
