Building hardware. Electrically controlled hold-open systems for fire/smoke door assemblies. Requirements, test methods, application and maintenance. | Status: Confirmed, Current

1 Scope This European Standard specifies requirements, methods of test and performance criteria against which the compatibility of components and their performance can be assessed when used in combination to form an electrically controlled hold-open system. It also specifies requirements for the integrity of such hold-open systems when connected to fire detection and fire alarm systems or other systems, including the signal exchange and technical data for interfaces. This European Standard provides requirements for the application of electrically controlled hold-open systems used for fire/smoke doors in buildings, where such doors are required to be self-closing. It covers planning, design (see Annex A), installation (see Annex B), commissioning, use and maintenance (see Annex E) of hold-open systems, intended for the protection of life and/or the protection of property. This may also include hold-open systems, or components of the hold-open system, that are self-contained in a single enclosure. Electrically controlled hold-open systems manufactured, installed and serviced in accordance with this European Standard are recommended for use wherever there is a requirement for reliable hold-open and release of an individual self-closing fire/smoke door assembly in the case of fire. The use of hold-open systems for closures in conveyor systems conforming to EN 1366‑7, which applies in conjunction with EN 1363‑1, may require additional proof of suitability, which is not covered by this European Standard. This European Standard does not cover design, installation, commissioning, use and maintenance of building fire detection and fire alarm systems (covered by CEN/TS 54‑14) but does cover the connection of hold-open systems conforming to this European Standard to building fire detection and fire alarm systems, under certain prescribed conditions. This European Standard does not cover the requirements of performance characteristics and operational environment conditions of particular components of a hold-open system, where these requirements are already covered by European specifications, and which include appropriate test methods to assure reproducible test results for the product conformity assessment. These European Standards are referred to in Clause 5. This European Standard does not cover electrically controlled systems used for smoke venting purposes or systems that allow the door to remain open under fault conditions (i.e. not fail-safe). This European Standard does not cover electrically controlled hold-open systems that are not connected to main power supply and are battery powered only.
