2.4.1Outputs/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
7.0amps (refer to battery calculations section). Each circuit is supervised,
The NACs can be converted to Style Z (Class A) by installing two optional Class A Converter module. Refer to
Class B Notification Appliance Circuits (supervised and
