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, 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 26.

Note: Short Circuit Supervision must be enabled when using the

 

 

REL-4.7K for Canadian Applications. Refer to the section titled

 

 

"Release Circuit 1 or Release Circuit 2" on page 58 for information

 

 

on enabling short circuit supervision.

 

Ferrite Bead (P/N 29150)

Large gauge wire should be looped through bead at least once as illustrated. Smaller gauge wire can be looped more often.
