Fire & Smoke Control Systems

Fire and smoke control systems are critical life and safety.

About the service

Fire and smoke control systems are critical life-safety installations and require regular inspection, testing and maintenance to ensure that they remain capable of performing their intended function.

Our commissioning process is structured around establishing that systems have been correctly set to work, regulated and tested and that the required operating conditions have been achieved. For air distribution systems, our methodology can be aligned with CIBSE Commissioning Code A: Air Distribution Systems (2024), which covers the setting to work, functional testing and regulation of ventilation and ductwork systems. CIBSE also identifies the importance of commissioning planning, system inspection, functional testing, regulation, performance testing and documentation. Where appropriate, BSRIA BG 49 – Commissioning Air Systems and other relevant industry guidance can also be considered alongside the project specification and design requirements.

What we offer

AOVs & Smoke Ventilation

We inspect and test Automatic Opening Vent systems and associated smoke ventilation equipment, including controls, actuators, fans and associated components. Testing can include functional operation and verification of system sequences to establish that the installation responds correctly to the relevant activation conditions.

Smoke Extract Ventilation

We provide testing and verification of mechanical smoke extract systems, including associated fans, dampers, controls and ventilation components. Testing can incorporate airflow and pressure measurements, functional checks and verification against the available design criteria.

Car Park Extract & Smoke Control

Car park ventilation and smoke extract systems require regular inspection and testing due to their role in both day-to-day ventilation and, where designed for this purpose, smoke control. We can undertake testing of associated fans, controls, dampers and system operation, providing clients with documented results and identification of any areas requiring further investigation.

Stair Pressurisation

We undertake performance testing of stair and escape-route pressurisation systems. Testing can include pressure differential measurements, airflow assessment, door condition checks and verification of system operation and control sequences. For applicable smoke-control and pressure-differential systems, testing may be undertaken with reference to the relevant sections of the BS EN 12101 series, together with the project design criteria and applicable fire-safety requirements.

Smoke Curtains

Inspection and operational testing of smoke curtain systems can be undertaken to establish that equipment deploys and operates correctly and that associated controls and interfaces are functioning as intended.

HVAC Testing & Commissioning

We provide testing, commissioning and verification services for heating, ventilation and air-handling systems.

About Our Process

We can provide support throughout the commissioning and handover process. Our procedures are designed to ensure that works are properly planned, recorded and reported, providing clients with confidence in the results obtained. The objective is to provide documentation that remains useful to the building owner and facilities management team throughout the operational life of the installation.

Planning

Establishing the scope of testing, required documentation, programme and access requirements before works commence.

Inspection

Reviewing installations and identifying issues that may prevent successful testing or commissioning.

Testing

Carrying out functional and performance testing using appropriate calibrated instrumentation and agreed procedures such as test sheets, inspection records, remedial recommendations and more.

Verification

Reviewing results against the applicable design criteria, specifications, standards and system requirements.

Remedial Support

Providing clear information regarding defects or performance issues so that remedial works can be effectively targeted.

Re-Testing

Returning to site where required to verify that identified issues have been rectified and that the system subsequently achieves the required performance.

Documentation

Providing clear records of testing and verification to support project completion, handover and future maintenance.

Quality Assurance

Quality and traceability are fundamental to effective testing and commissioning.
