Dorgard Fire Door Retainer

Overview

Dorgard is a wireless fire door retainer designed to allow fire doors to remain open during normal day-to-day use while ensuring they close automatically when a fire alarm is heard. By enabling doors to close when needed, the system helps compartmentalise a building and reduce the spread of fire and smoke.

This solution is especially suitable for care homes, schools, hospitals, offices and other buildings where open fire doors improve accessibility, ventilation and convenience. The acoustic activation principle eliminates the need for complex wiring, making installation faster and more practical in both new and existing buildings.

Dorgard can hold a fire door open at virtually any angle and includes a user-settable timed daily release, audible warning and battery-powered operation. Its compact and practical design offers a simple way to improve everyday movement through a building without compromising fire safety performance.
