The Dorma TS73EMF is a specialised door control solution that combines a standard hydraulic door closer with an integrated electromagnetic hold-open device. This system is engineered primarily for use on fire and smoke check doors where it is necessary to hold the door open during normal operation while ensuring it closes automatically in the event of a fire.

Functionally, the unit allows the door to be held at a fixed point, improving pedestrian flow and accessibility in high-traffic commercial or public buildings. When connected to an external smoke detection system or fire alarm, the electromagnet releases upon signal interruption, allowing the hydraulic closer to shut the door securely. This makes it an essential component for fire safety compliance in corridors and escape routes.

Typical applications include hospitals, schools, and offices where barrier-free access is required without compromising fire safety protocols. The TS73EMF is designed for door fixing and is compatible with various single-leaf door configurations. It is suitable for both new installations and as a replacement unit for existing fire door hardware systems.

FAQs

Yes, it is specifically designed for use on fire and smoke check doors. When linked to a smoke detection system, it provides a reliable method for controlled hold-open while ensuring the door closes securely in an emergency.

To operate as a certified hold-open system for fire protection, this device must be used in conjunction with an external smoke detection system, such as the DORMA RMZ-K/S, which monitors the area and controls the power to the unit.
