[Current]Fire detection, warning, control and intercom systems — Control and indicating equipment, Part 16: Emergency warning control and indicating equipment
This Standard specifies requirements, test methods and performance criteria for emergency warning control and indicating equipment (EWCIE) as the main component of an emergency warning system (EWS). This Standard covers three Grades of EWCIE to suit different risks and regulatory requirements. The additional requirements for each Grade are set out in Appendix A.
