2-9 NOTIFICATION APPLIANCE CIRCUITS
The ARIES Control Unit has two notification-appliance circuits (NACs) that are labeled NAC1 and
NAC2. These circuits have field-wiring connections that terminate at TB5 and TB14, respectively.
Each NAC can supply up to 1.5 A of current at a nominal 24 Vdc for polarized notification
appliances. Total current output of the ARIES power supply must not exceed 5.4 A.
Both circuits are supervised, power limited, and are compatible with conventional, UL-Listed, 24-
Vdc notification appliances. They can also be used with the following synchronizable horns
and strobes:
• MT Series Multi-Tone Horns and Horn/Strobes
• NS Series Horn/Strobes
• NH Series Horns
• RSS(P) Series Strobes
The NS Series notification appliances provide the option to use silenceable horns and non-
silenceable strobes on the same NAC. Refer to the ARIES Programmer’s Guide to configure one
or both NACs for use with the NS Series notification appliances.
