Power Supply Wiring Distances

Overview

Class A NAC Wiring Table

Before wiring from any type of power supply to notification appliances, check Tables 5-1 and 5-2 for wiring distances.

Table 5-1 lists the maximum distances from the NAC terminal block to the last appliance in a Class A (loop) configuration, depending on wire gauge and current. Use Table 5-1 to calculate wire distances for your application if you are using Class A wiring.

Notes:

Max Distance = distance from SPS to last appliance.

This table is calculated at 49 degrees Centigrade.

Distances are based on a 3V drop, and take into account the worst-case panel output voltage. These distances are based on the worst case of having one single load at the furthest point.

If circuit integrity wire is used instead of housing cable in a fire-rated enclosure, reduce wiring distances by 12 m for every 3 m of potential exposure.
