The existing fire alarm system at Liverpool John Lennon Airport (LJLA) was obsolete, requiring LJLA to undertake a significant technological investment in critical life safety systems to enable quick and efficient response to emergencies. With over 400,000 people passing through the airport per month, the reliability of the fire alarm system is crucial, not only to rapidly identify the source of a fire, but to distinguish a false alarm from a real event. In the event of a real fire, the engineering team need to have control over the crisis with maximum visibility of the incident.
HESIS were tasked with replacing the obsolete fire alarm system with our technology of choice: the Honeywell Gent system. The challenge was to upgrade over three phases, during the daytime and evenings whilst the airport was fully operational. This created a unique challenge, as the building needs to have a fully functioning fire alarm at all times.
