22 Mass Notification — P/N LS10063-000NF-E:E 06/26/2019
Programming Programming
If an input categorized as MN goes active, ZF20 activates and can suppress fire signals for all nodes in the MN mapping when MN is the 
highest priority in the system.
Open the DVC Inputs branch. Because the DVC is set to ACU, LOC, CCS or Subsidiary mode, the first 14 Input lines will show MN 
default input priorities. Assign the MN category to mass notification inputs, the Fire category to fire inputs, the MN Active Tone cate-
gory to the MN Active Tone input, and the General category to inputs that are neither MN, Fire, or MN Active Tone.
 
 Set the Input Priority
The priority for input sources can be modified from the default priority. The priority of the inputs should be modified to group inputs of 
similar categories together. That is, in a system that has prioritized MN events over fire, all inputs associated with MN should be 
assigned to the “MN” category and re-prioritized to be higher than fire inputs. “Fire” category inputs should be prioritized above “Gen-
eral” category inputs. Figure 3.15 on page 27 illustrates inputs grouped and prioritized by category.
The priority of the input is also used to prioritize network audio. In a system that utilizes multiple DVCs, the default configuration 
assigns priority to the local microphone input over the microphone input from a network source. To prioritize a network DVC over the 
local DVC, reassign the priority for the Network Paging rows to a lower number (and therefore a higher priority) than that of the Local 
Paging rows.

Assign categories to all 
Inputs as appropriate.
If MN is the highest priority 
in the system, select the 
MN category for all Level 1 
Inputs and the Fire 
category for all Level 2 
Inputs.
If Fire is the highest priority 
in the system, select the 
Fire category for all Level 1 
Inputs and the MN 
category for all Level 2 
Inputs.
Assign the MN Active Tone 
category to the MN Active 
Tone input.
If a Fire Active Tone input 
is required, assign it to the 
Fire category

Use the Up & Down buttons to reassign 
the priority of an input.
Select Category from the 
drop-down choices.
Note: Inputs 31-1000 represent 
Audio Message Sequences, created 
and labeled on the DVC’s Audio 
Settings branch as described in the 
DVC Manual.
