Replacement of AOV's within High Rise Residential Blocks, Rabbs Mill House, Sutcliffe Hse & Harding Hse

These vents play a crucial role in meeting fire safety regulations for high-rise buildings. The vents are designed to activate when smoke is detected in the communal areas, particularly the floor corridors. The current AOVs are included in the maintenance contract for the fire detection equipment. However, after a recent servicing, it has been recommended that these units should be replaced due to their age and reliability issues. The age of these units surpasses the recommended life cycle replacement according to Chartered Institution of Building Services Engineers (CIBSE) guidelines, and they also fail to comply with the latest British Standards (BS) such as BS1201, BS9999, and BS7346-8. Whilst the existing systems are operational, it is recommended that we begin a phased replacement and upgrade to ensure that all the High-Rise Residential Buildings continue to have operational AOVs.
