EN 54 & NFPA 72 Compatibility • Generally NFPA 72 and BS 5839-1 strive to achieve a common objective: A system providing safe evacuation and sufficient protection for life and property. • The NFPA 72 Code does not restrict the designer to the exclusive use of products that are tested to US standards. As per

- 1.5.1 “Nothing in this Code shall prevent the use of systems,

methods, devices or appliances of equivalent or superior quality, strength, fire resistance, effectiveness, durability and safety over those prescribed by this code”

47

Basic Fire All 2004-v2.ppt

- Clause F.2 states “Standards and Codes. The following standards

and codes are referenced explicitly or implicitly regarding the design, installation, testing, maintenance and use of these systems and their components. These were used when developing this standard, but are not necessarily required practice for manufacturers” Honeywell Advanced Fire Alarm 2009-V1 30-06-09.ppt
