Milton Keynes Magistrates
Project Delivery
Speakers
Specify and supply 106 speakers, installed in the same positions as the existing units to minimise impact on the building fabric.
Head End Equipment
Supply, fabricate, deliver and commission a new system complete with fireman’s mic, paging mic, and court microphones.
Design
Full design package for a fully compliant EN54 system — specifications, power calculations, required circuits, and speaker power requirements.
Commissioning
Out-of-hours commissioning programme followed by full operator training and a comprehensive STI survey at handover.
The Story
Maywin Electrical approached Voxiss to develop a two-part design for updating the PAVA system at Milton Keynes Magistrates’ Court.
Their original plan covered two years — restoring the public address function first, then introducing a full EN54 voice alarm system. During our first site visit, however, we confirmed that the existing cabling had been recently updated and was already compliant. This meant only the head-end equipment and speakers required replacement.
That single discovery made it possible to deliver both phases together in one programme, removing a year of planned downtime and delivering full EN54 compliance in a single contract.
Working alongside the Maywin Project Manager, Voxiss set out how circuits could be zoned, where new PA circuits were needed, what cabling was required for the microphone family, and provided the full migration plan from old to new system.
After commissioning, full operator training and an STI intelligibility survey were completed before handover.
Challenges
Distribution had to be minimised to avoid any subsequent making-good works to walls and finishes.
All new circuit routing had to remain within walls and drop ceilings — nothing surface mounted.
No drawings or records of the existing installation were available, and the existing system was not functional — all routing had to be discovered on site.
Limited space available for the new central head-end equipment within the existing comms room.
