St Clements Court Leigh-on-sea Essex

Project type: Radio Fire Alarm, Sprinklers, Smoke VentilationInstallation Date: Aug 2011- Mar 2012Value: £180,000.00

Following a fire risk assessment in 2011, the fire safety systems were deemed to be inadequate for the risk and WFP were asked to tender for the works to replace the fire system, install new smoke vents and install a new sprinkler system in the basement car park.

WIRE-FREE PROTECTION - CASE STUDY

SpecificationSt Clements Court is a 1930's period building located on the Essex coast in the picturesque town of Leigh-on-Sea. Following a Fire Risk Assessment (FRA) there was initially deemed to be a requirement for smoke ventilation within the building and sprinkler cover for the basement car park. The building is constructed in a figure of eight and arranged in two joined blocks each with a central core, one core has a rising atrium from the first floor to the roof-light. Each of the 62 flats open on to a landing, evenly split across the cores. When specifying of the smoke ventilation was underway, additional consideration was given to the early detection of smoke within each core in addition to alerting the residents within the individual dwellings.

The basement of the building has a residents car park and protection of the building with both heat detection and sprinkler suppression was required to provide early warning and a means of containing the fire prior to the arrival of the fire brigade.

Installed System Focus - Fire Alarm

At St Clements we designed, installed and commissioned an EMS Firecell 4 loop radio fire detection and alarm system; covering the roof plant room, reflective beam detectors within the Atrium, automatic smoke detection on each floor with combined sounder/high temperature heat detectors within each flat lobby providing early warning for the building tenants.

Fire System architectureThe system is distributed using radio clusters, each cluster can control up to 32 devices including sounders and interfaces, the radio signals can hop from one cluster to another to reach the radio hub which controls the whole system in conjunction with the main control panel. In this installation a total of 14 radio clusters and over 100 radio detectors and call points were utilised to provide early warning of a fire and to open the smoke vents when required.

Installation The system was installed during three phases, the initial phase was the control panel, which as located in a temporary position near the location of the existing system as well as the radio cluster communication (RCC) infrastructure on the floors. Once this was in place and communicating well, our project manager pre-arranged appointments to access the 62 flats to install the radio combined heat sounders within the flat lobbies. The system was left in soak test whilst we arranged a return visit to carry out final commissioning of the fire alarm system as the final phase.
