UL recently posted a Public Notice issued on September 12, 2012 (Release 12PN-51) regarding changes to certification programs that impact fire resistive, fire resistant, and circuit integrity cables. The following link takes you to this UL’s Public Notice page:http://www.ul.com/global/eng/pages/corporate/newsroom/newsitem.jsp?cpath=%2Fglobal%2Feng%2Fcontent%2Fcorporate%2Fnewsroom%2Fpublicnotices%2Fdata%2Ful-and-ulc-announce-important-changes-to-certification_20120912090000.xml. Additionally, UL Fire Safety Council Task Force, in which IAEI participated as a member, offers the following as additional background and recommendations:

LOCATION OF THESE WITHDRAWN SYSTEMS

These systems are primarily installed in mixed occupancy high-rise buildings, and in tunnels, bridges, and other commercial infrastructures. In many circumstances, the referenced systems exist in conjunction with other fire mitigation system options, which are not in question.

Within a building or structure, the locations of these systems are primarily found in critical locations such as, but not limited to:

  • Fire pump room
  • Elevators
  • Smoke control systems
  • Command center in a large building
  • Pressurized stairways
  • Smoke management systems
  • Building fire alarm systems
  • Electrical Equipment Rooms – Feeders/Service
  • Life safety alarm systems

RECOMMENDATIONS FOR BUILDINGS CLOSE TO COMPLETION OR AWAITING SIGN-OFF

We recommend you consider a "performance approach” to assessing the building’s unique situation. First, utilize a team to review and identify risks in the building (e.g. are there duplicitous systems in place and is there a need for an additional fire mitigating system?) Specific to the installed or almost installed ECPS, guide the team to consider the following variables:

  • Distance of cable in ECPS
  • Location of current system
  • Redundant systems currently in place
  • Is COPS classification essential to owner?
  • Number of stories in building
  • Use of the building
  • Occupancy of building
  • Fuel loading
  • Sprinkler set up
  • Fire alarm systems

Assessing these variables will help your team evaluate risk and determine next best steps. Because there is so much variability to buildings that may have an Electrical Circuit Protective Systems (ECPS), it is impossible to recommend one solution to fit all building/structure types.
