AOV installation is within the capabilities of most mechanical and electrical contractors, however, it should be approached with care and expertise. We recommend that any contractor installing AOV systemas has undergone expert training and holds relevant 3rd party certification.
What are AOV kits?
When a fire breaks out, there needs to be some means of removing smoke from communal lobbies or corridors adjoining the escape stairwell such as an automatic opening ventilator (AOV) or a natural/mechanical smoke shaft system. As smoke is extracted through these systems, the stairwell ventilator provides replacement air to allow people to escape safely and firefighters to enter the building.
Our AOV systems contain ventilators, control panels, smoke detectors and switches designed to work out of the box without the need for specialist installation or commissioning service. Although smoke control systems can be onerous to design and install for complex buildings, self-installing the majority of smoke shaft and AOV systems is very similar and well within the capability of a competent trade contractor.
Main contractors who want to self-deliver MEP services, and M&E or fire alarm contractors who would like to bring smoke control in house, can take advantage of this kit approach alongside professional training and gain many benefits.
What are the key steps to self-installing smoke control and AOV systems?
In line with the recent trend among main contractors to self-deliver MEP services, some M&E and fire alarm contractors are following a similar route by bringing smoke control in-house. If you’re thinking about taking on AOV installation yourself or looking to hire an M&E contractor for your AOV installation, here are some key points you should consider:
- Ensure you learn about smoke control for residential buildings. Standards and regulations should be met, the most important being The Building Regulations 2010, specifically Approved Document B.
- Determine who in the organisation will be responsible for this area of the project and if training is required, invest in a recognised training course. The Group SCS Approved Contractor Network offers a range of training courses covering design, installation and commissioning of smoke control for multi storey residential developments.
- Engage with the right supply chain partners who can offer high quality, CE marked products. Group SCS offers a range of AOV kits designed to simplify AOV installation by electrical contractors. These are available off the shelf and are all supported by the Group SCS commissioning and service network.
AOV Installation: What are the benefits of self-installing?
- Product savings: Purchasing a kit works out better value than buying the individual components. Our Approved Contractors also receive discounts on the product range
- Improve profit: Bringing AOV installation in-house instead of subcontracting can improve margins
- Tried and tested configurations: Ensure compatibility between equipment and designed to meet the requirements of Approved Document B of the building regulations
- Reduce project time: Our kits are modular so less time needs to be spent on system design and the kits can be shipped in a very timely manner to improve project delivery
- Control of risk: Self-install can limit risk of non-performance from third party subcontractors
- Customisation: The kit system is compatible with additional controls, smoke detectors, wind/rain sensors – all supplied by Group SCS, which can be added when required without the need to replace the original system.
