FEATURE


The majority of the design work was completed in a live environment, using the VAD design tools provide by Honeywell Gent. This allowed HESIS to plot the dimensions of all areas, and use an app to test Lux levels for compliant design.


The system comprised of three fully networked new Honeywell Gent Vigilon fire alarm panels, thus allowing full functionality, visibility and control from several different locations. This is ideal for the engineering team and the fire service when dealing with an incident.


As part of the project there was also a requirement to interface with other systems onsite, including the PA/VA voice alarm system, and access control, along with all of the commercial units around LJLA. The largest challenge was the full integration, and mapping of the Cortech platform, which was again carried out by the HESIS engineering team.


Results and outcome The upgrade took place in the live airport environment, whilst keeping the original system operational, ensuring the safety of the passengers was a priority at all times.


The new network, installed specifically for the three main panels, is running successfully, providing full coverage from different locations.


Fully designed, installed and commissioned by HESIS, with no disruption to passengers, LJLA has now been upgraded to EN54-Part 23 and BS5839 Part 1:2017 compliance.


HESIS delivered a robust, intelligent system to address the issue of adequate fire protection in the distinctive high- volume facility that is Liverpool John Lennon Airport.

With over 400,000 people passing through the airport per month, 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.


Whilst there was no question the Honeywell Gent system was the technology of choice for HESIS. The challenge was to upgrade over three phases, during the daytime and evenings whilst the airport was fully operational. This created a unique situation, as the building needed to have a fully functioning fire alarm at all times.


The solution The robust Honeywell Gent system was selected as it provided full compliance with the fire system standard EN54 Part 23 and BS5839 Part 1:2017.


This means the product is capable of meeting the required Lux levels in all areas, providing visual indication of a fire alarm activation for the hard of hearing.
