The survivability of fire alarm circuits that must continue working during a fire has been required in the National Fire Alarm and Signaling Code® since 1999 and the Code has always addressed speaker circuits in emergency communications systems with a performance requirement for survivability. In more recent editions, the Code has been modified as the cable technology changed, and Circuit Integrity (CI) cable was developed to meet the needs of designers and installers for providing survivability to many critical circuits in a fire alarm system installation. This program will review the history of this issue and where the Code and the industry stands relative to Pathway Survivability. This presentation will focus on the correct application of Pathway Survivability in healthcare occupancies of various sizes and types.
