International Code for Fire Safety Systems (FSS Code) Updates

Chapter 9: Individually Identifiable Fire Detectors

Amendments to Chapter 9 of the FSS Code for fixed fire detection and fire alarm systems were adopted to clarify the fault isolation requirements for individually identifiable fire detector systems. New paragraph 2.18 was inserted to address systems installed on cargo ships and passenger ship cabin balconies. Where an individually identifiable system is fitted, isolator modules need not be provided at each fire detector if the system is arranged so that the number and location of fire detectors rendered ineffective due to a fault would not be larger than an equivalent section in a section identifiable system.
