Keeping people safe during a fire starts with a reliable, fully compliant AOV system, which is exactly what Oltec Services delivers to clients across Warrington, Cheshire. We specialise in the design, installation and maintenance of automatic opening vents built to meet EN12101-2 standards, ensuring smoke and heat are removed quickly while escape routes remain clear for occupants and emergency services alike. Our dedicated engineers carry out thorough testing and servicing so every vent, detector and control panel functions correctly, giving building owners genuine peace of mind that their fire safety system is dependable, compliant and ready when needed.

How Automatic Opening Vent Systems Work
Every automatic opening vent system installed by Oltec Services is built to perform a critical role during a fire emergency across Warrington, Cheshire. By keeping escape routes clearer, an AOV enables faster and safer evacuation while helping emergency services locate and control the fire more quickly. It also removes smoke and heat from the building, which significantly reduces structural property damage. Designed to work in unison with your fire alarm or detection system, the AOV automatically sends a signal to open rooflights, windows or vents as soon as smoke is detected, ensuring a coordinated response that protects both occupants and the building itself when every second truly counts, whatever the nature or scale of the incident.
AOV Testing, Servicing and Retrofit Solutions
Compliance does not end once an AOV system is installed, ongoing testing is essential to keep it fully functional. Oltec Services recommends testing automatic opening vent systems at least every six months, and our engineers carry out these scheduled inspections across Warrington, Cheshire to catch any faults before they become a serious risk. Retrofitting is also possible for older buildings, and we design bespoke AOV retrofit solutions that meet compliance standards without invasive structural alteration. During routine maintenance, we thoroughly inspect every detector, control panel and vent, then test the entire system under simulated fire conditions, ensuring your building remains protected, compliant and ready to respond the instant smoke is detected.


Types of Automatic Opening Vent Systems We Install
Every building has different smoke ventilation requirements, which is why Oltec Services installs a range of automatic opening vent types tailored to the property in question. Across Warrington, Cheshire we design and fit roof vents, window AOVs, vertical vents and more, ensuring the right solution is selected for schools, care homes, offices, HMOs and other multi occupancy buildings. Choosing the correct AOV type is critical, as roof vents suit certain layouts while window or vertical vents may better serve narrower stairwells or corridors. Our specialists assess each property individually, considering building height, occupancy and existing fire strategy, before recommending an EN12101-2 compliant AOV configuration designed to remove smoke and heat as effectively as possible.
The Benefits of a Fully Compliant AOV System
The importance of automatic opening vents for your property cannot be overstated. Professional design, installation and maintenance from Oltec Services across Warrington, Cheshire gives you genuine peace of mind that occupants and property are properly protected. By removing heat and smoke quickly, AOVs reduce the spread of fire, minimising potential structural damage and repair costs. Under Building Regulations, automatic opening vents are also a legal requirement for many multi occupancy buildings, including schools, care facilities, offices and HMOs, making compliance essential rather than optional. Most importantly, AOVs maintain a smoke free layer at lower levels, giving occupants vital extra time to escape safely, which ultimately means a properly functioning AOV system genuinely helps save lives.
