Door Retainer
A door retainer is a device designed to hold open fire doors in a safe and controlled manner. Fire doors are essential components in the passive fire protection of a building, designed to prevent the spread of fire and smoke between different compartments. However, keeping fire doors closed at all times can be impractical and inconvenient, especially in high-traffic areas. This is where door retainers come into play, offering a solution that combines safety with accessibility.
Door retainers are interfaced with the fire alarm system so upon a fire activation the fire doors will close and keep the fire spread under control.
Multiple types of door retainer can be fitted depending on the type and location of the doors, from wall mounted to swing free overhead types and a full wire free system can also be installed which negates the need for a full wiring installation and offers a quick and unobtrusive installation.
Door retainers will be tested as part of the fire system planned maintenance schedule.
