Retrofit Life-Safety Systems

As an integrator or electrical contractor bidding on a contract for a fire-alarm system in an existing structure, for instance a commercial or residential high-rise building, Radix Wire’s DuraLifeTM FPL cables are the ideal solution for meeting the mandatory fire alarm survivability circuit requirements in the National Fire Protection Code (NFPA 72).

There are multiple ways to satisfy the NFPA 72 pathway survivability requirements. In some cases, newly-constructed buildings feature two-hour rated enclosures. Think of these as shafts or chimneys rising vertically, hidden from visibilty behind the wall. They are made of no less than 2″ thick concrete or masonry, thereby protecting standard fire-alarm cables from harm in a fire event.

But two-hour rated enclosures are expensive! And in existing structures, they’re not always present or feasible to install. Enter Radix Wire’s DuraLifeTM FPL UL 2196 circuit-integrity cables installed in conduit – they’re flexible and easy to install, they come with industry-leading EMT fill rates allowing you to run up to 10 cables in a single EMT (vertically or horizontally) substantially reducing total install costs as compared to the competition, and they’re considerably less expensive than alternative circuit-integrity solutions such as MI (mineral insulated) cables.

Retrofitting a critical life safety fire-alarm system in an existing structure has never been easier! Please contact Eli, the CI Guy, at 216-400-6719 or via email at for more information and to discuss your project today.
