Project Overview

Trinity Fire and Security Systems are delighted to be working on the Fire Detection and PAVA upgrade for Heathrow’s Terminal 3 building. The project incorporates the full replacement of the Fire Detection and PAVA system architecture and final completion of the multi million pound project is due in December 2017.

Trinity Experience

The project methodology has been designed to replace the whole system out of hours whilst keeping a fully working system 24/7, thus giving zero operational impact to Heathrow and its passengers. All installation and commissioning takes place at night, including the replacement of 11000 devices and integration into a new full fibre network backbone. Currently the project is running ahead of schedule and has been awarded Mace Aviation’s top performing project for 2016.
