Booster Power Supply Manual

24 Vdc Notification Appliance Circuit (NAC) specifications

The NAC cable must be a minimum 18 gauge. Distance limits
are determined using the maximum allowable circuit resistance
and cable manufacturer's specifications. Restrictions apply when
calculating the wire size for the NACs:

1. Minimum supply voltage available is 18.9 V.
2. Minimum required circuit voltage at any NAC is 17 Vdc.
3. Maximum alarm current required for all NACs.

Using Ohm's law, the NAC current requirement, and a voltage
drop of 1.9 volts (18.9 - 17), the maximum allowable NAC
resistance is determined as follows:

drop

max

= Maximum allowable NAC resistance

max

= -------

max

= Maximum NAC current requirement

max

drop

= Maximum allowable voltage drop

from power supply to NAC

Using this formula, the maximum permissible circuit resistance
for a loaded (2.5 A) circuit is 0.76

as follows:

0.76

Ω

2.5 A

Using the Load vs. Distance table, the maximum allowable length
(D) of any listed wire gauge pair is determined as follows:

D = Distance in feet

D = ------- X 1000

Using this formula, the maximum length of a loaded (2.5 A) NAC
using a pair of 14 AWG wires is:

0.76

146.1' = ------- X 1000

146 feet is the maximum length of a loaded (2.5 A) NAC branch
circuit using a pair of 14 AWG wires.
