Power Supply Wiring Distances
Overview Before wiring from any type of power supply to notification appliances, check Table 6-1 and
Table 6-2 for wiring distances.
Class A NAC
Wiring Table
Table 6-1 lists the maximum distances from the NAC terminal block to the last appliance in a
Class A configuration, depending on wire gauge and current. Use Table 6-1 to calculate wire
distances for your application if you are using Class A wiring.
• Max Distance = distance from SPS/RPS to last appliance.
• This table is calculated at 49 degrees Centigrade (120 degrees Fahrenheit). If you are installing in
locations that could be exposed to higher temperatures, refer to NEC Table 8.
• Distances are based on a 3 V drop, and take into account the worst-case panel output voltage.
• If circuit integrity wire is used instead of housing cable in a fire-rated enclosure, reduce wiring
distances by 38 feet (12 m) for every 10 feet (3 m) of potential exposure.
