EN 50518 is a European Standard that specifies the requirements and procedures for the design, installation, commissioning, and maintenance of alarm transmission systems used for the transmission of alarm signals from security systems to alarm receiving centers (ARCs). The standard covers both wired and wireless alarm transmission systems and is intended to ensure that such systems are reliable, secure, and effective in transmitting alarm signals to ARCs.
EN 50518 includes requirements for the components of alarm transmission systems, such as control panels, alarm transmission equipment, and communication networks, as well as guidelines for testing, maintenance, and monitoring of these systems. The standard also provides guidance on the use of different types of signaling protocols, such as Contact ID and SIA, and specifies requirements for their use.
The standard was developed by the European Committee for Standardization (CEN) and is widely used in Europe as a basis for the certification of alarm transmission systems. Compliance with EN 50518 is often required by insurance companies, regulatory bodies, and other stakeholders in the security industry.
