42 Mass Notification — P/N LS10063-000NF-E:E 06/26/2019
Operation Paging
An MN page at a DVC-RPU will:
• Give control to its assigned LCD-160, which will maintain its Controls Active LED on and maintain control functions as
unblocked.
• Turn off Control Active LEDs and block control functions at all other panels and annunciators.
An MN alarm that is not activated by an MN page:
• NCA-2’s and NFS2-3030’s (in network display mode) will remain in control: their Controls Active LEDs will remain on and their
control functions will remain unblocked.
• NFS2-3030s not in network display mode, NFS2-640’s, and NFS-320/SYS’s will extinguish their Controls Active LEDs and their
control functions will be blocked.
4.5 Paging
When a system has MN capabilities, the second column on a
DVC or DVC-RPU keypad has three functional buttons repre-
senting three priority levels of paging. If MN is the highest
priority in the system, pressing the highest button will create
an MN page locally and to all MN mapped nodes, initiating an
MN alarm and suppressing fire activations. If Fire is the high-
est priority, pressing the highest button in column two will
create a Fire page to all mapped nodes. Pressing the Level 3
(GENERAL PAGE) button will create a general ALL CALL
page that will not suppress any fire activations.
Buttons in the two right columns of the keypad can also create
an MN alarm if programmed to do so.
ACU’s take priority over LOC’s, and LOC’s take priority over
CCS’s.
4.6 Drill Operation
Drill operation is blocked while fire activations are suppressed. So if MN is the highest priority in the system, an MN Alarm on the local
panel or on a network panel that is MN Mapped, drill operation, including custom drill operation, will be blocked. This is to prevent the
user from activating fire outputs while a mass notification is in progress.
