Fan Sensors & Switches

Inbuild UK’s Fan Sensors are designed to provide accurate monitoring and feedback for ventilation, smoke control, and mechanical air movement systems. These sensors play a vital role in ensuring fans operate correctly, efficiently, and in accordance with system requirements.

Fan sensors detect key parameters such as airflow presence, fan run status, temperature, and pressure, feeding real-time data back to fan control panels, smoke ventilation controls, or building management systems (BMS). This allows systems to confirm fan operation, trigger alarms, or adjust performance automatically.

Key product features include:

• Monitoring of airflow and fan status
• Detection of temperature and pressure conditions
• Real-time feedback to control panels
• Integration with ventilation and smoke control systems
• Enhanced system safety and reliability
• Fast response for fault detection
• Durable design for continuous operation
• Supports regulatory and life safety compliance

Inbuild UK’s Fan Sensors ensure ventilation systems perform as intended, providing confidence in both everyday operation and emergency conditions.

Yes. They support compliance with Part F (ventilation) and Part L (energy efficiency).

Yes. They should align with BS EN 15232-1, which covers building automation and its impact on energy performance.

All electrical devices should carry UKCA (or CE in NI) marking and comply with BS EN 60204-1 and BS 7671.

Yes, but they must comply with Approved Document B and BS EN 12101 for life safety applications.

Yes. Automated operation can cut energy use by 30–40%, supporting compliance with Part L.

At least annually for residential, and more frequently for commercial/industrial use. Some sensors may require calibration checks.

Note that on some applications, such as HRB’s with sensors used in smoke venting systems, more frequent checks may be required.

Yes. Fans controlled by sensors should comply with BS 8233:2014 indoor noise level guidance in sensitive environments.

Some simple devices may be DIY, but commercial and industrial installations should be carried out by qualified electricians in line with BS 7671.

Smoke venting systems and other life safety systems should only be installed by competent persons.

Temperature and humidity sensors are most effective for comfort and moisture control in homes.

Yes. Smart switches can integrate with BMS for centralised control, data logging, and optimisation of ventilation systems.

Inbuild UK supplies a wide range of compliant fan sensors and switches. Our solutions are designed to meet UK Building Regulations and British Standards while delivering energy efficiency, comfort, and safety across residential, commercial, and industrial applications.
