EN 1155: Building Hardware - Electrically powered hold-open devices for swing doors - Requirements and test methods

Standard: EN 1155: Building hardware - Electrically powered hold-open devices for swing doors - Requirements and test methods

Certification: CE Marking: Electrically powered hold-open devices for swing doors should meet the requirements as described in the standard EN 1155, which is a harmonized standard under the Construction Products Regulation (EU) 305/2011.

Scope: This European Standard specifies requirements for separate hold-open devices and also for holdopen mechanisms incorporated in a door closer intended to be used on fire/smoke compartmentation doors. 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. ln 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.

Door closing devices are covered by EN 1154.

NOTE : The series of European Standards EN 54 covers the requirements, test methods and performance criteria of resettable smoke/fire detectors.
