6. What are some important safety precautions to consider when choosing fire alarm cable?

There are many safety precautions such as voltage, abrasion resistance, chemical resistance, etc., that should

be considered in choosing any kind of electrical cable, including that for fire alarms. However, there are some

notable fire-related safety precautions to consider as well. First is the fire resistance of the cable – will it burn

and/or how long will it burn? Another is smoke propagation -- how much will it give off if it comes in contact with

fire? These considerations should be made when choosing any type of electrical cable, but they are especially

important in the case of fire alarm cable which must function in emergency situations and under extreme


Most safety concerns (including these fire-related ones) are regulated by the UL, NEC, and other standards

organizations and guidelines. The NEC outlines acceptable limits for burning and smoke emissions while the UL

and other organizations are responsible for the development of various flame tests cables must pass in order to

be considered safe for use.
