Q: What gauge fire-alarm cable do I need?

A: Wire gauge is an important consideration when choosing fire-alarm cable, because fire alarms require higher voltages to operate than other multiconductor applications. It is important to ensure that the required amount of power is reaching each fire alarm in the system. The AWG correlates to the amount of resistance. Lower AWG (thicker cable) has less resistance than higher AWG cable:

Wire Gauge Resistance
18 AWG 6.5 Ohms
14 AWG 2.6 Ohms

To determine whether the fire alarm cable will meet your needs, calculate whether your power supply will provide enough power for the last device in the system when you account for the amount of energy usage by each previous device and the resistance of your cable run.
