The cables support critical life safety applications in hospitals, high-rise buildings, airports, stadiums, etc. They are vital in locations where evacuation times are beyond the capabilities of standard fire alarm cable or when partial evacuation is required. As a 2-hour fire rated cable, VITALink® cables are designed to last in a burning infrastructure and remain operational to ensure building occupants can evacuate safely.

VITALink® cable must be installed with specific components in accordance with a set of detailed guidelines for UL 2196 and ULC S139 Electrical Circuit Integrity Systems No. FHIT.40A and FHIT7.40A, with Hose Stream Test.
