4.10 NAC Operation
There are two programmable NACs (Notification Appliance Circuits) resident on the MS-9050UD
main circuit board which can be wired for Style Y (Class B) or Style Z (Class A) . Both NACs may
be programmed as silenceable or nonsilenceable and may also be programmed for steady or coded
operation. Coded operation provides a choice between March Time, Temporal or California cod-
ing.
4.11 Programmed Zone Operation
Each addressable detector and monitor module can be assigned to a maximum of five software
alarm zones. A general alarm zone Z00 may be listed for output (control) points, but it is not nec-
essary to list Z00 for input points, since this is the default zone for all alarm input devices. Zone
Z00 is not activated by supervisory points.
When an input device alarms and is not disabled, it activates all software zones assigned to it. An
output device that is not disabled is turned on when any of the software zones to which it is pro-
grammed become active. Only fire alarms can turn on any of the two main NACs.
Note that hazards/tornado alerts do not turn on the two main NACs.
