Sets out requirements for the design and manufacture of equipment used in emergency warning and intercommunication systems installed in buildings to ensure warning in the event of an emergency and assist in the subsequent orderly evacuation of the buildings. Distinctive, easily recognizable, visible and audible signals are specified for the emergency warning system and an independent, integrated emergency intercommunication system between a control centre and other control points is described. Appendices provide information on typical systems and detail test procedures.

This Standard sets out minimum requirements for the design and manufacture of the equipment used in emergency warning and intercommunication systems, which are installed in buildings to ensure warning in the event of an emergency, and assist in the subsequent orderly evacuation of the building.
