Registration is closed

Due to the severe weather, our previously scheduled guest presenter, Steve Carman, is unable to attend the March meeting.  Larry Rietz will replace Steve as the speaker for tomorrow's meeting.  For those interested in hearing Steve speak, he will be presenting at our 6th Annual Fire Protection Symposium this April.     

Presentation:  Surviving Survivability – A User’s Guide to Survivable Fire Alarm Circuits

The survivability of fire alarm circuits that must continue working during a fire is required in the National Fire Alarm and Signaling Code®. Over many code cycles, 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. Then on 12 September 2012,Underwriters’ Laboratories (UL) summarily pulled the listings for all CI Cable. This action left many designers, AHJs, and contractors with no cost effective way to meet the Code requirements for survivability. UL has finally finished the new standards for CI cable both for free air and in raceway and the Code has added further changes of note. This program will review the history of this issue and where the Code and the industry stands relative to survivable fire alarm cable.

This presentation will feature the following learning objectives:

  • What is the Code history of circuit survivability?
  • What fire alarm circuits must be survivable and how can this be accomplished?
  • What effect does product listing have on survivable cable?
  • How can a designer provide and an AHJ approve a survivable cable installation?
