2.4 Output Circuits
2.4.1 Outputs/Notification Appliance/Releasing Circuits
Each of the four Style Y (Class B) Notification Appliance Circuits can output a maximum of 3.0
amps of current. Total current drawn from these as well as other DC power outputs cannot exceed
7.0 amps (refer to battery calculations section). Each circuit is supervised, power-limited and
provides special application power. Refer to the Device Compatibility Document for a listing of
compatible notification appliances.
The NACs can be converted to Style Z (Class A) by installing two optional Class A Converter
module. Refer to “CAC-5X Class A Converter Module” on page 29.
