2.4.1Notification Appliance Circuits

The MS-2 provides one Style Y (Class B) NAC (Notification Appliance Circuit) while the MS-4 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 MS-2 or 6.0 amps for the MS-4 with the optional second transformer installed (refer to battery calculations section). Each circuit is supervised and power-limited. Refer to the Fire•Lite Device Compatibility Document for a listing of compatible notification appliances.

The MS-4 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 (MS-4 only)" on page 25.
