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 Appendix 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.
