Fire Cable UL1424

Fire alarm cables are cables that are used to provide power as well as signals to fire alarm safety systems. Because of the special use of this cable, often these signal cables need to be fire resistant and low smoke and halogen free in order to be used in the event of a fire.

This cable is primarily used for emergency lighting, fire observation, signal sensing sensor systems, exhaust fan systems, communication intercom systems, equipment control systems, fire pumps, and fire alarm system circuits.
