Professional pa & voice alarm systems across Hitchin

Hitchin is a historic market town in North Hertfordshire with a thriving mix of independent businesses, listed buildings, and modern commercial premises. Our engineers are experienced working in conservation areas and older buildings where specialist solutions such as wireless fire alarms are often required.

Hitchin's commercial fabric is dominated by Grade-II-listed buildings around the market square, Churchgate, and Bancroft. Most installations here are wireless fire alarms or surface-cabled discreet CCTV — modern intrusive cabling routinely fails listed building consent.

For pa & voice alarm systems in Hitchin, 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 Hertfordshire, including north Herts Council's conservation officers regularly reject standard hardwired fire alarms in listed premises; wireless systems with concealed sounders are typically required to gain listed building consent.

For pa & voice alarm systems in Hitchin, send us photos, drawings or an existing specification and we will tell you what can be priced from those and what needs a site check.

What's included in our pa & voice alarm systems service

Design to BS 5839-8 & EN 54-16

Voice alarm designed to BS 5839-8 using EN 54-16 control equipment and EN 54-24 loudspeakers, with zoning matched to your evacuation strategy.

Speech Intelligibility (STI)

Speaker layouts designed and commissioned to achieve the required Speech Transmission Index so evacuation messages are clearly understood throughout the building.

Fire Alarm Interface

The system is interfaced to the fire alarm so activation triggers pre-recorded evacuation and alert messages automatically, zone by zone.

Phased & Zoned Evacuation

Different messages to different zones — evacuate, alert, or stand-by — supporting phased evacuation in larger and high-rise buildings.

Combined Public Address

The same speaker network delivers live announcements, paging and background music day to day, with fire messages always taking priority.

Monitoring & Certification

Fully fault-monitored amplifiers, speaker lines and microphones, handed over with a commissioning certificate, zone plan and O&M manual.

Frequently asked questions about pa & voice alarm systems in Hitchin

What is a PAVA system in Hitchin?
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. We never quote Hitchin jobs from a postcode alone: a free survey confirms what the building actually needs before any price is fixed.
Why use voice evacuation instead of just a fire bell in Hitchin?
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 Hitchin?
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 Hitchin?
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 Hitchin?
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 Hitchin?
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.
Do you have engineers near Hitchin?
Yes — Hitchin is around 25 minutes from our Luton base, and our engineers are in the Hertfordshire area most working days. Surveys are free and usually arranged within a couple of days.
How quickly can you attend a site in Hitchin?
You'll hear back within 24 hours. For pa & voice alarm systems in Hitchin we can usually get the survey booked within 2–3 working days — sooner if something's genuinely urgent.
Can you take over servicing of an existing system in Hitchin?
Usually, yes. We take over maintenance of most makes of pa & voice alarm systems systems in Hitchin, starting with a condition check so you know exactly what state the system is in before a contract begins.
