scope:

This European standard specifies requirements for the manufacture, performance and testing of electrically controlled escape exit systems, specifically designed for use in an emergency situation on escape routes. These systems consist of at least the following elements: . Requesting element for requesting the release of electrical locking element in order to exit; . Electrical locking element for securing an emergency exit door; . Electrical controlling element for supplying, connecting and controlling electrical locking element and requesting element. . In addition, these electrically controlled escape exit systems can include time delay and/or denied egress mode. This European Standard covers escape exit systems placed on the market as a complete unit (e.g. mortise lock, lever handle, cylinder, keeper, requesting element, electrical locking element, electrical controlling element, etc.). The components are tested as a single product. NOTE 1 The suitability of a time delay and/or egress mode should be defined according to local regulations. NOTE 2 The suitability of an electrically controlled escape exit system for use on fire/smoke resisting door assemblies is determined by fire performance tests conducted in addition to the performance tests required by this European Standard. Annex B indicates additional requirements for these products. NOTE 3 This European Standard covers electrically controlled escape exit systems which are either manufactured and placed on the market in their entirety by one producer or assembled from sub-assemblies produced by more than one producer and subsequently placed on the market as a kit in a single transaction. This doesn't preclude components being delivered separately. The manufacturer is responsible for making it clear in a 'list of components' as part of the manufacturer's compulsory installations which combination of components is covered by the ITT.
