EVS-EN 54-21:2006

This European Standard specifies requirements, test methods and performance criteria against which the effectiveness and reliability of routing equipment capable of transmitting fire alarm and/or fault warning signals for use with fire detection and fire alarm systems installed in buildings can be assessed (see EN 54- 1). The routing equipment is designed to allow the system to function in accordance with the requirements of this European Standard. It also provides for the evaluation of conformity of the equipment to the requirements of this standard.
