Technical Specification Sheet

Communication & Audio

Public Address & Intercom Infrastructure Engineered for High-Clarity Speech.

[Technical Asset: Communication & Audio]Asset pending final approval.

Engineering Architecture

We supply and integrate commercial public address (PA) systems, two-way talkback intercoms, and audio-visual infrastructure. Designed for demanding acoustic environments like transport hubs, warehouses, and commercial offices, ensuring crystal-clear communication and emergency broadcasting.

Procurement Compliance Standards

All systems specified on this schedule adhere strictly to British Standards (BS EN guidelines) and incorporate privacy-masking features to satisfy UK GDPR digital evidence requirements. We specify energy-efficient equipment sized to actual site risk rather than inflating invoice values.

Public Address (PA)Multi-Zone 100V Line Audio Distribution & High-Efficiency Ceiling/Horn Speakers

Engineering Definition: High-voltage audio transmission system allowing dozens of loudspeakers to be connected over long cable runs with minimal signal loss.

Voice Evacuation (PA-VA)BS EN 54-16 Compliant Emergency Voice Evacuation Broadcast Controllers

Engineering Definition: Certified life-safety audio matrices with monitored speaker lines and backup amplifier failover for emergency broadcasting.

Two-Way TalkbackIndustrial Hands-Free Intercom Stations with Background Noise Cancellation

Engineering Definition: Heavy-duty communication points utilizing active acoustic echo cancellation to enable clear speech in noisy industrial settings.

Audio-Visual (AV)Commercial Meeting Room & Control Room AV Distribution Networks

Engineering Definition: Structured HDMI over Ethernet and wireless presentation switching engineered for corporate boardrooms and security operations centers.

Acoustic EngineeringSpeech Intelligibility Optimization (STI) for High-Reverberation Spaces

Engineering Definition: Acoustic modeling and speaker placement designed to achieve a Speech Transmission Index exceeding 0.50 in echo-heavy environments.

System IntegrationSIP / VoIP PBX Telephone Network & Security Management Software Integration

Engineering Definition: Session Initiation Protocol integration allowing security intercoms to be answered directly from standard corporate desk phones or mobile devices.
