This British Standard gives recommendations for the processing of signals by an alarm receiving centre (ARC) from alarm systems, such as but not limited to fire detection and fire alarm systems, fixed firefighting systems, intrusion and holdup alarm systems, video surveillance systems, social alarms systems, lone worker, and combinations of such systems.

NOTE BS EN 50518:2019 provides guidance on planning, construction, systems, management processes, leadership, governance, management and staffing of an alarm receiving centre. BS 5979 and BS 8591 also provide guidance.
