Q: <strong>How often must Smoke Ventilation (AOV) systems be serviced?</strong>

Under the Regulatory Reform (Fire Safety) Order 2005 , smoke ventilation systems must be maintained in efficient working order. We recommend a bi-annual service (every 6 months) to ensure sensors, panels, and actuators are fully operational. Regular maintenance ensures compliance with your insurance policy and keeps your building logbook up to date.

Q: <strong>Can you replace a broken motor on an existing AOV?</strong>

Yes, we specialise in retrofitting and repairs . If you have a failed actuator (chain or linear drive), we can identify the correct replacement force and stroke length to match your existing window profile, often without needing to replace the entire window frame.

Question 1

How often must Smoke Ventilation (AOV) systems be serviced?

Accepted Answer

Under the Regulatory Reform (Fire Safety) Order 2005, smoke ventilation systems must be maintained in efficient working order. We recommend a bi-annual service (every 6 months) to ensure sensors, panels, and actuators are fully operational. Regular maintenance ensures compliance with your insurance policy and keeps your building logbook up to date.

Question 2

Do you provide certification for your AOV installations?

Accepted Answer

Upon completion of a smoke ventilation project, we perform a full functional test of the installation. Once verified, the operational testing report is handed back to SE Controls for final commissioning and life-safety certification. As an SE Controls Approved Partner, our installations adhere to BS EN12101 standards, ensuring you have the correct paperwork for Building Control handover.

Question 3

Can you replace a broken motor on an existing AOV?

Accepted Answer

Yes, we specialise in retrofitting and repairs. If you have a failed actuator (chain or linear drive), we can identify the correct replacement force and stroke length to match your existing window profile, often without needing to replace the entire window frame.

Question 4

What is the difference between a standard electric window and an AOV?

Accepted Answer

An AOV (Automatic Opening Vent) is a life-safety device linked to a smoke detection system. It must use certified actuators tested to high heat resistance and reliability standards (EN12101). Standard comfort ventilation motors are not compliant for use in smoke control zones like stairwells or lobbies.

Question 5

My high-level manual window winders are stiff or stuck. Can they be repaired?

Accepted Answer

In many cases, yes. Stiff operation is often caused by a lack of lubrication in the conduit or a worn operator handle. We can service existing Teleflex and Hindle systems to restore smooth operation. If the gearing is damaged beyond repair, we can replace the specific components rather than the whole system, saving you money.

Question 6

What is the maximum distance for a manual window opener?

Accepted Answer

A well-installed Hindle manual system allows for flexible positioning, but there are physical limits to ensure smooth operation. We recommend a maximum horizontal run of 30 metres and a maximum vertical rise of 10 metres. For longer distances or complex runs, we recommend electric automation.

Question 7

Do you install manual window controls for mental health facilities?

Accepted Answer

Yes. We supply and install anti-ligature window controls specifically designed for secure environments. These systems feature enclosed conduit and removable handles (or folding operators), ensuring patient safety while allowing staff to manage ventilation.

Question 8

Do you handle the electrical wiring for the actuators?

Accepted Answer

We specialise in the supply and mechanical installation of the system. We mount the actuators, fit the brackets, and ensure the closing forces are perfect. We then provide your on-site electrical contractor with the wiring diagrams and technical data to complete the power connection. This ensures clear lines of responsibility and safety compliance on site.

Question 9

Can existing manual windows be converted to electric?

Accepted Answer

Absolutely. This is one of our most popular services for schools and offices. We remove the old manual winding gear and retrofit modern electric chain actuators. These can then be controlled by wall switches, remote controls, or integrated into a Building Management System (BMS).

Question 10

Can the windows close automatically if it rains?

Accepted Answer

Yes. We can integrate rain sensors and wind sensors into the control panel. This ensures that roof vents and high-level windows automatically close during bad weather to protect the building interior.

Question 11

What areas of the UK do you cover?

Accepted Answer

Window Control Installations operates nationwide. From our base in Dunstable, we support projects across the UK, with established relationships in London, the Home Counties, and major cities throughout the country.

Question 12

Are your engineers qualified to work on construction sites?

Accepted Answer

Safety is our priority. All our lead engineers hold current CSCS cards and are IPAF/PASMA certified for working at height. We provide comprehensive Risk Assessments and Method Statements (RAMS) for every project before work commences.

Question 13

Can you take over a project if the current installer is failing to deliver?

Accepted Answer

Yes. We are able to step in and help rescue projects where the incumbent supplier has missed deadlines or failed compliance checks. We can conduct a rapid site survey to assess the quality of the existing installation, identify any remedial works required, and provide a clear plan to get your system commissioned and handed over.
