The intricacies of the architecture, woodwork and brickwork of such an old building, coupled with the depth of two levels of cellars presented a number of interesting challenges to consider when implementing a workplace fire alarm system. In order to ensure the safety and protection of a grade II listed building and its valuable contents, a high level of technical understanding and expertise was required.
During the refit, Tecserv had to re-locate a number of detectors and transmitters as well as ensure all equipment was fully integrated and could be monitored and controlled easily.
Tecserv UK had installed the existing fire alarm systems back in 2004. This install had followed an extensive survey and fire risk assessment to take account of the ability for radio frequencies to penetrate the thickness of brickwork as well as other risk factors such as the building use, aesthetics, access routes, and the value of items to be protected. As a result of this detailed assessment, a hybrid fire alarm system encompassing both a wired analogue addressable fire alarms system and wireless fire alarm system was chosen.
In 2017, as a result of a number of new build extensions and recent renovations that had been done to the interior of the existing buildings, a review of the effectiveness of the fire alarm system was conducted. This review also considered the impact of recent EU changes whereby the radio frequency over which fire alarm control panels and detectors receive a signal would change. Consequently, a decision was taken to implement a fire alarm system upgrade and replace the wireless fire alarm system with new technology as well as install the latest technology into the newly built areas.
