Royal College of Surgeons
A two-phase PAVA modernisation collapsed into a single delivery — restoring public address operation and adding full EN54-compliant voice alarm capability in one programme, with comprehensive STI verification at handover.
Project Delivery
Design
A new EN54-compliant PAVA system designed to a no-single-point-of-failure (NSPOF) topology, reusing the existing speaker circuits and FAP configuration where appropriate.
Supply
Supply and fabrication of two new PAVA racks, with delivery to the RCSI campus in Dublin.
Commissioning
Out-of-hours commissioning of the new system over two evenings, with both old and new systems running in parallel before final cutover.
The Story
Voxiss partnered with IC Services Limited to design and supply a new EN54-compliant PAVA system for the Royal College of Surgeons campus in Dublin.
The project began as a planned renewal — the previous system was outdated and unsupported. Partway through the design stage, the existing system failed entirely, creating a tight turnaround for delivery.
Voxiss accelerated the design process, securing client approval in just 7 days. Fabrication of the new racks was completed and delivered to site within 3 weeks.
Working alongside the existing maintenance team, Voxiss engineers helped identify and resolve faults across the legacy estate before the system changeover.
Commissioning was carried out over two evenings, with both old and new systems operating together before switching fully to the new setup — eliminating any window of uncovered occupation across the campus.
The work was completed on time, and ongoing maintenance support is now active under a long-term agreement.
Challenges
Introducing the new system whilst keeping the existing system live throughout the design, supply and commissioning programme.
Rectification of legacy faults required close working with the incumbent maintainer to avoid commercial conflict.
Design had to proceed on incomplete information, with planning explicitly accommodating discoveries and changes during commissioning.
Works planned and delivered around active academic semesters, with overseas equipment delivery into Ireland adding logistical complexity.
Lead times reduced significantly when the legacy system was found to be inefficient and not meeting EN54 requirements — full compliance had to be achieved at speed.
