Boss Electromagnetic Hold Open Door Closer for Busy Fire Doors
Electromagnetic door closers with hold open are suited to fire doors in high traffic areas such as corridors, hospital wards, and public buildings. The hold open function allows doors to remain open during normal use to support access and movement throughout the building.
This Boss electromagnetic door closer releases automatically on fire alarm activation or power failure, allowing the door to close in a controlled manner. This ensures the door performs its fire safety function when required, helping to protect escape routes and maintain effective compartmentation.
The unit is tested to EN 1154 and EN 1155, CE marked, and Certifire approved. It is suitable for timber fire doors up to 120 minutes and steel fire doors up to 60 minutes. Always check the fire test evidence for your door to confirm fire door hardware compatibility.
For applications that require electromagnetic swing free operation, the Boss TS7.004 emag door closer provides a suitable alternative.
Cam Action Door Closer for Improved Accessibility
The cam action mechanism reduces the force required to open the door, supporting compliance with BS 8300 and improving ease of operation. This is particularly important in environments where doors must remain accessible while still providing controlled closing.
Backcheck is included on all Boss TS6.SA-EMF door closers to help prevent the door from opening too quickly and causing damage. The EN 2-5 models also include delayed action, allowing a short pause before the door begins to close. This provides additional time for users to pass through and supports more accessible use in busy environments.
If hold open functionality is not required, the Boss TS6.224 cam action mechanical door closer offers the same controlled closing performance. For concealed installations, the Boss ITS6.224 cam action concealed door closer provides a more discreet solution.
