Main Menu - User Programming
NAC Type The NAC circuit can be programmed to activate for specific applications. Select Mass
Notification to turn on the NAC circuit only for a mass notification event, Fire Evacuation to turn
on the NAC circuit only for a fire evacuation event, Both to turn on the NAC circuit for both mass
notification and fire evacuation events, or Follow Input to have the NAC follow the input from an
external source (connections to TB18). To use Both, the Unit Operation must be set to Combina-
tion. Refer to "Unit Operation" on page 61.
NAC Protocol The programmer can select the notification appliance coding or strobe synchroni-
zation by selecting the corresponding drop-down box. Select System Sensor for System Sensor syn-
chronization, Wheelock, for Wheelock synchronization, Gentex for Gentex synchronization, or
Steady, for a continuous output with no coding.
To ensure proper strobe and circuit operation, there is also a limit to the number of strobes that can
be attached to each circuit. Following is a list of the strobes that have been tested with the ECC and
the maximum number that can be connected to each NAC. Make sure that the NAC maximum cur-
rent is not exceeded.
Aux Power Selects whether this power is Constant or Resettable use from TB17.
Speaker Volume Control NAC If the Cooper Wheelock SP-SVC module is installed on TB23
of the main control board, allowing manual volume setting for telephone paging and background
music for a specific speaker or speaker zone, select Enabled.
Console Priority Priority can be assigned to the operator consoles so that the primary operator
interface can always override the functions at the local operator consoles or remote microphones.
Select POC->LOC->RM for console priority. Selecting Equal for priority allows users with access
to the system on a a "first come, first served" basis.
