Installation Notification Appliance Circuits
2.5 Notification Appliance Circuits
The control panel provides four Style Y (Class B) or four Style Z (Class A) NACs (Notification
Appliance Circuits) when using the optional ZNAC-92 Class A converter module. Each circuit is
capable of 2.5 amps of current. Total current in alarm for all external devices cannot exceed 6.0
amps (refer to “Calculating the System Current Load” on page 159). Use UL listed 24 VDC notifi-
cation appliances only. Circuits are supervised and power-limited. Refer to the Device Compatibil-
ity Document for a listing of compatible notification appliances. The NACs, which are located on
the main circuit board, may be expanded via the FCPS Series field charger/power supplies.
The following sections describe the configuration and wiring of Style Y and Style Z Notification
Appliance Circuits on the MS-9200UDLS main circuit board.
