Node Port Aco Alarm Interface - Zhone IMACS 8000 User Manual

Interface Card
The node port uses an RJ48 connector. Pins 3, 4, and 5 uses an RS485 compatible form
c-contact closure that can be used to report ACO alarms to an external system. Pins 1, 2, 6 and
7 are reserved for future use. Pin 8 is ground.
Connection of the ACO alarm interface to an external alarm device (such as a buzzer or light)
alerts you to problems with the system. Figure 8-12 shows a possible configuration connecting
a unit to a generic external alarm system. The nominal input is 5V and the short-circuit current
is 250mA.
The alarm interface is activated by the ACO setting. This will activate the device when a
designated alarm occurs.
