What is a Fire Door Holder/Retainer?

In any building, fire safety is of paramount importance. Fire doors play a crucial role in preventing the spread of fire and protecting lives and property. Among the various components that contribute to fire door functionality, fire door holders/retainers are essential devices that aid in maintaining fire door integrity.

A fire door holder/retainer is a device designed to keep fire doors in the open position, allowing easy access and smooth traffic flow during normal operations. It consists of a magnetic or mechanical mechanism that holds the fire door open and releases it automatically during a fire alarm or power failure, enabling the door to close and effectively compartmentalize the spread of fire.

Fire door holders/retainers are typically connected to the building’s fire alarm system or an independent power supply. They are commonly installed on walls, floors, or overhead structures near the fire doors, and they are equipped with sensors to detect alarms or power disruptions.

1. Enhanced Egress: By utilizing fire door holders/retainers, occupants can easily pass through doorways without obstruction, improving accessibility and flow. This is particularly important in high-traffic areas, such as hospitals, schools, and commercial buildings.
2. Fire Compartmentation: In the event of a fire, fire door holders/retainers release the fire doors, allowing them to close automatically. The swift closure prevents the fire from spreading beyond the compartment, containing it and limiting its potential damage.
3. Smoke Control: By closing the doors promptly, these devices minimize the infiltration of smoke into unaffected areas, reducing health hazards and facilitating safe evacuation.
4. Compliance with Building Regulations: The Building Regulation 2010 part B outlines regulations regarding fire door retainers . Compliance with these regulations ensures that buildings meet the necessary safety standards and are adequately protected in the event of a fire.
5. Integration with Fire Alarm Systems: When a fire alarm is triggered, the devices receive a signal to release the doors, allowing them to close automatically. Seamless integration enhances the overall fire safety system, ensuring a coordinated response and minimizing the potential for human error.
