Overview of Fire Alarm Cable

In case of a fire emergency, fire alarm systems will save lives by serving its purposes. Every single piece of fire alarm equipment is important, in which fire alarm cable maybe one little thing that are easily to be ignored. The fire alarm cable is the backbone of any fire alarm system. It carries signals from room to room. Fire alarm cable varies from conductor options, colors, safety ratings, and environmental ratings, etc. 


Definition of Fire Alarm Cable

Fire alarm cable plays a key role in the security systems. While it is a fire alarm cable, there are many uses for it such as smoke alarms, smoke detectors, voice communications, microprocessor-controlled systems, pull boxes (fire alarm signals), burglar alarms, and other low voltage applications. When it comes specifically to fire alarm systems, fire alarm circuits control and power applications such as safety functions, elevator capture and shutdown, door release, and damper control.


Fire Alarm Cable Ratings

When buying fire alarm cable, one of the most important things to consider is the fire rating. There are three essential fire safety ratings that are: FPL, FPLR, FPLP.

FPL – FPL cable is suitable for general-purpose applications, excluding installation in air ducts, plenum spaces, riser closets, and any other space where environmental airflow occurs. These cables are resistant to fire and pass UL test 1424 and vertical flame test 1581.

FPLR – Riser rated fire alarm cable is suitable for vertical runs in elevator shafts and run going floor to floor. These cables have fire-safe characteristics, such as the ability to self-extinguish and produce a low amount of toxic smoke. They prevent fire from traveling from floor to floor. Riser cables must pass UL test 1424 and vertical riser test 1666.

FPLP – Plenum rated fire alarm cable is suitable for use in plenum spaces, air ducts, and other environmental airflow areas. They have the ability to self-extinguish and produce a low amount of toxic chemicals and smoke upon burning. These cables pass UL test 1424 and Steiner tunnel test 910.


Other options to consider

Shielded Fire Alarm Cable. Shielding is the best way to offset electromagnetic interference (EMI). Shielded fire alarm cable reflects outside energy and conducts it to the ground. In systems where there are a lot of cable runs and electronic equipment, getting shielded cable will give you a clear signal without interference.

Gauge size –18AWG is the smallest size that cables should adopt. The smaller the gauge, the larger the wire. Larger wire means less resistance for current flow. Getting a larger or smaller gauge is important when considering the applications and the distance of the run because resistance increases with distance.

Number of conductors – For various appliances and equipment, conductor numbers will be 2 or more.
