2.4 Output Circuits
2.4.1 Notification Appliance Circuits
The Flex 402 provides one Style Y (Class B) NAC (Notification Appliance Circuit) while the Flex
404 provides two Style Y (Class B) NACs. Each circuit is capable of providing a maximum of 2.5
amps of current. Total current drawn from these as well as other DC power outputs cannot exceed
3.0 amps for the Flex 402 or 6.0 amps for the Flex 404 with the optional second transformer
installed (refer to battery calculations section). Each circuit is supervised and power-limited. Refer
to the Gamewell-FCI Device Compatibility Document for a listing of compatible notification
appliances.
The Flex 404 NACs can be converted to Style Z (Class A) by installing the optional Class A
Converter module. Refer to "CAC-4 Class A Converter Module (Flex 404 only)" on page 24.
