This European Standard specifies requirements for separate hold-open devices and also for hold-open mechanisms incorporated in a door closer. Electrically powered hold-open devices for swing doors manufactured according to this European Standard can hold a swing door at a fixed position or can allow the door to swing freely. In each case interruption of the electrical supply will cause the controlled door to close positively.
Electrically powered hold-open devices manufactured in accordance with this European Standard are recommended for use wherever there is a requirement for reliable hold-open and release of self closing fire/smoke door assemblies.
Whilst these devices can incorporate smoke or fire detection elements, the performance of those particular elements is outside of the scope of this European Standard.
NOTE : The series of European Standards EN 54 covers the requirements, test methods and performance criteria of resettable smoke/fire detectors.
