RS ISO 7240-19: 2007
Fire detection and alarm systems — Part 19: Design, installation, commissioning and service of sound systems for emergency purposes

Abstract

This part of ISO 7240 specifies the design, installation, commissioning and service requirements for a sound
system for emergency purposes (s.s.e.p.; see ISO 7240-1:2005, Figure 1, item C), which is primarily intended
to broadcast information for the protection of lives within one or more specified indoor or outdoor areas during
an emergency. The s.s.e.p. is intended to initiate a rapid and orderly mobilization of occupants in an
emergency by including systems using loudspeakers to broadcast voice announcements for emergency
purposes, alert signals complying with ISO 7731 (where applicable) and evacuation signals complying with
ISO 8201. In some cases, sound systems are used in preference to sounders or bells in order to broadcast a
range of coded warnings that is difficult to communicate with sounders or bells.
The use of the s.s.e.p. for normal sound reinforcement and distribution systems purposes under
non-hazardous circumstances is not excluded. When used for non-emergency purposes, the zoning of the
loudspeakers can differ from the zones used for emergency purposes.
This part of ISO 7240 does not apply to sound systems that use bells or sounders.
