Knowsley Heights, Liverpool

UK & Ireland

Following a significant programme of compartmentation works undertaken in 2018, the 11-storey Knowsley Heights buildings have benefitted from a refit that includes installation of Advanced’s EvacGo system, which is compliant with the BS 8629 Code of Practice, for the design, installation, commissioning, and maintenance of evacuation alert systems for use by fire and rescue services in England and Wales.

Knowsley Heights is owned by Livv Housing Group, an independent housing association, with the two buildings partially managed by an onsite manager. ABM Fire and Security Ltd undertook the complete, supply, installation and commissioning of the EvacGo systems. A 4-loop, 16-zone evacuation alert panel was installed in each building.

Each EvacGo panel is housed inside a STS 205 security-rated enclosure with patented BS EN 1303-compliant lock and key mechanism for exclusive access by the fire and rescue service – ensuring minimal risk of unauthorised use and full compliance with BS 8629. Argus Vega Sounder VADS audible and visual devices and interfaces were installed in the hallways of each of the 128 flats to ensure all residents, including people who are deaf or have hearing loss are kept safe and informed.

Tony Cahill, Executive Director-Property from Livv Housing Group said “EvacGo from Advanced was selected for the Knowsley Heights refit as it was essential that the evacuation alert system met the criteria for BS 8629. While it may not be mandatory for an 11-storey existing building, meeting with best practice is essential for us as a housing association to protect our customers in the event of a fire.”

All Advanced evacuation alert systems are custom-manufactured to reflect each individual building’s evacuation zones and have been developed to provide a bespoke solution that allows the fire services to control evacuation floor by floor according to the severity and location of the fire. BS 8629 guidance states that the evacuation alert control system should be installed where a ‘stay put’ policy is in force, such as with Knowsley Heights, so that it can be used to facilitate a timely and ordered evacuation for all residents. An evacuation alert system is vital to help fire and rescue services inform residents of a change in evacuation strategy during an incident. This gives fire and rescue services an additional tool to use on the ground, alongside existing methods of evacuation. It must be standalone, with its only function being to assist fire and rescue services in the evacuation of the building.

Published on 1 June 2022, Part B (Fire Safety) offers new improvements to fire safety guidance to ensure tall buildings are made safer in England, as part of a wider package of reforms. Installation of evacuation alert systems will be mandatory in all new build residential apartment blocks over 18m from 1st December 2022. However, for all other new build and retrofit projects, complying with BS 8629 is still seen as best practice which is why Advanced’s EvacGo has been selected and installed at Knowsley Heights.
