Intelligent fire detection

When the fire alarm and detection system at the Wellcome Trust Centre for Human Genetics (WTCHG) needed replacing, Oxfordshire based Pyrotec Services was asked to look at the existing system with a view to total replacement, which included renewing all existing devices and control panels, the retention wherever possible of all existing wiring, the provision of loop powered sounders, the enhancement of detection coverage, and improvement of access for maintenance purposes in certain areas, particularly within ceiling voids and lift shafts. In line with the University of Oxford Safety Office's policy of open protocol systems, together with commonality of equipment, Hochiki devices and Kentec control panels are used for all replacement and new systems.

It was agreed that the new system be based around the Enhanced Systems Protocol (ESP). Stuart Davies, Hochiki's marketing manager, comments: "ESP is a robust total communications solution for intelligent fire detection and fully integrated systems. It has a multipurpose structure that provides the flexibility and expansion to accommodate simple addressable systems through to integrated building management and safety systems. It is a robust system and perfectly suited for organisations such as WTCHG, where maximum reliability and minimum disruption from unwanted alarms are essential."
