Alarm Output Reporting
During a Critical or Major alarm condition on BROADway, the normally open contact (pin 1) is closed,
and the normally closed contact (pin 3) is opened.
During a Minor alarm condition on BROADway, the normally open contact (pin 4) is closed, and the
normally closed contact (pin 6) is opened.
Alarm Cut Off (ACO)
The Alarm Cut Off button on the front I/O panel is used to silence the current alarm output. A new alarm
will re-activate the alarm closures.
Installing the NSP101 Control Card
The NSP101 control card is the heart of the BROADway system and contains the narrowband switch
matrix, the integrated IP router, the network timing synchronization subsystem and the management
interface into the BROADway node.
BROADway always requires at least one NSP101 card to operate. Two NSP101 cards can be installed
to provide redundant operation of the system. If a single NSP101 is used it should be installed in the
NSP-1 card slot. The second, redundant NSP101 should be installed in the NSP-2 card slot.
