Door Holders
Fire door retainers are an essential part of any fire safety strategy in buildings where doors are required to remain open under normal operating conditions but must automatically close during a fire. At Firesense, we supply a robust and versatile range of Cranford Controls fire door retainers, including wall-mounted, floor-mounted, and pole-mounted models. Designed to work seamlessly with fire alarm systems, these retainers ensure that fire doors close promptly and securely in the event of an alarm, helping to contain smoke and fire and protect critical escape routes. Our door retainers are engineered with flame-retardant materials and built to the highest standards, providing reliable performance and long service life. Suitable for commercial, residential, healthcare, and public buildings, the range we stock supports full compliance with UK fire safety regulations, including BS 7273-4, which covers door release mechanisms activated by fire alarms.
Wall-Mounted Door Retainers
Wall-mounted models are among the most popular and widely used fire door retention solutions. These units are fitted to the wall at the door’s hold-open position and offer a clean, discreet appearance. Firesense stocks both 24V and 230V wall-mounted door retainers, each providing a 200N holding force, which is sufficient for most standard internal fire doors. The Cranford Controls wall-mounted range includes standard and metal-bodied flame-retardant variants, offering added durability and fire resistance. These retainers are designed to release the door immediately when the fire alarm system is activated or if power is lost, allowing a door closer to return the door to the closed position without delay.
They are easy to install, compatible with a wide range of door closers, and suitable for new-build or retrofit applications. Ideal for corridors, communal spaces, and access routes in care homes, offices, and schools, wall-mounted retainers strike a balance between convenience and compliance.
Floor-Mounted Door Retainers
Where wall mounting is not practical—due to glass panels, architectural features, or space limitations—floor-mounted door retainers offer a practical alternative. Firesense supplies the Cranford Controls 24V floor-mounted door retainer, which provides the same 200N holding force as its wall-mounted counterparts. These retainers are designed for discreet low-level installation and are particularly useful in environments where visual impact needs to be minimal or where installation flexibility is required. Like the wall-mounted models, they are flame-retardant, reliable, and respond instantly to a signal from the fire alarm panel or a loss of mains power.
Pole-Mounted Door Retainers
For larger or heavier fire doors—or for installations where the mounting point must be further from the door—pole-mounted door retainers offer an ideal solution. Firesense stocks the Cranford Controls 24V pole-mounted retainer, which provides a high holding force of 1000N. This makes it suitable for wide double doors or doors fitted in high-traffic areas, such as hospitals, sports complexes, and airports. Pole-mounted retainers are often used in specialist installations where additional reach is required. These models are just as responsive and robust as other types in the Cranford Controls range, ensuring immediate release during an alarm condition.
Keeper Plates and Accessories
To ensure a complete and secure installation, Firesense also supplies accessories such as the Cranford Controls 302-005 Keeper Plate, which comes with a 1-metre chain. This allows for flexibility in positioning and alignment between the retainer and the fire door, ensuring secure operation and compliance across a variety of layouts.
