The Dorma TS73EMF is a precision-engineered door control solution that combines a high-performance hydraulic door closer with an integrated electromagnetic hold-open device. This unit is specifically designed for fire and smoke check doors, providing the convenience of a held-open door for high-traffic areas while ensuring critical safety protocols are met.

When integrated with a smoke detection system or the building's main fire alarm, the TS73EMF maintains a stable hold-open position. Upon receipt of a fire signal or a loss of power, the electromagnetic lock releases, allowing the hydraulic closer to safely and reliably shut the door. This makes it an essential component for maintaining fire compartmentation in commercial and public environments.

Typical applications include hospital corridors, schools, and offices where ease of access is required during normal business hours. This frame-fixed version is suitable for universal application and is frequently used alongside the Dorma RMZ-K/S smoke detection range. It serves as both a primary installation unit and a technical replacement for existing fire safety door hardware.
