EN 50518:2019 + A1:2023 defines requirements for Monitoring & Alarm Receiving Centres (MARC/ARCs): physical security, technical infrastructure, staffing & procedures, and business continuity (fallback sites). It replaces the former 2013 Parts 1–3 and updates requirements.
Our approach: consultancy, audit preparation and technical implementation within the agreed EN 50518 scope.
Access control to critical rooms and environmental protection.
The standard defines two ARC categories according to the types of alarm messages handled. Category I handles security messages, such as intrusion and hold-up alarms, and has higher requirements for construction, security and integrity than category II. Category II handles other messages, such as fire and social alarms. A category I centre can also handle category II messages.
Minimum requirements for alarm reception, verification and response by monitoring/alarm receiving centres (MARC/ARC).
The 2019 edition consolidated Parts 1–3; A1:2023 introduced clarifications and updates.
Category I handles security messages and has higher requirements for construction, security and integrity. Category II handles other messages, such as fire and social alarms. The type of alarm messages determines the category.
