Technical Services

We offer a technical consultancy service, where we can design and build a suitable fire protection system for your building. We can design and build everything from mechanical fire and smoke control to passive fire protection for your buildings.

You can rely on Onyx to create compliant, capable fire protection systems for your buildings with our extensive experience and expertise. Here are some solutions that we are able to design and install for and in your buildings.

Why Choose Onyx as Technical Consultants?

Onyx is accredited in all three third party BM Trada Q-Mark Installation and Maintenance schemes (certificate number 1145). Our certifications demonstrate that we are capable of fire stopping installation, fire door installation and fire door maintenance in buildings of all kinds in a variety of sectors, such as healthcare and education.

We meet the requirements of the Regulatory Reform (Fire Safety) Order as competent to install passive fire stopping products. We also comprehend how passive fire protection affects compartmentation in buildings such as hospitals and schools.

Motorised Fire and Smoke Dampers

Motorised fire and smoke dampers are usually linked to a fire alarm. If a fire alarm is triggered, this would trigger the motorised fire and smoke dampers to close. The closing of the dampers prevents the spread of fire and smoke, keeping both in one compartment and slowing its progress. Motorised fire and smoke dampers prevent fire and smoke progressing into other areas of a building, allowing occupants to evacuate unharmed.

Smoke Extract Systems

Smoke extract systems are designed to remove toxic smoke and fumes from a building in the event of a fire. Smoke extract systems can be autonomous or manually triggered. These type of extract systems have fans at the top of a mechanical shaft that activate to remove the smoke and fumes from the building they are installed in. These fans prevent smoke from travelling to other areas of a building.


A fire door is a door that is fire-resistant, another example of passive fire protection. Firedoors combined with all the components that make them fire-resistant and prevent smoke surpassing them are known as doorsets.

Doorsets are used to prevent the spread of fire and smoke for as long as possible, preventing fire and smoke passing into other building compartments. Doorsets usually have a fire-protection rating and need regular maintenance to ensure they would be effectual should they be needed.


Fire walls, fire barriers and fire partitions are all fire-resistant barriers that are used to prevent the spread of fire from the area that it started in. This type of passive fire protection aims to contain a fire and nullify its threat to the rest of a building by enclosing it in one space.

Fire walls, fire barriers and fire partitions are all fire-resistant barriers designed to prevent the spread of fire from the compartment of a building that it began in. Firewalls are strategically placed to ensure the containment of a fire, so occupants of the building have the opportunity to safely evacuate. Combined with fire sprinklers and other reactive fire protection, the threat of fire and smoke can be contained and nullified.
