Alarm Origination/Remote Access Connection

The DEFINITY AUDIX system can be connected to a remote location through a
remote access connection. This connection can be used to transmit alarms and
perform remote maintenance. For instance, when the DEFINITY AUDIX system
detects a major malfunction, it closes an alarm relay and can transmit the alarm
condition to a remote service center. Technicians at the remote location can then
connect to the DEFINITY AUDIX through the modem connection and perform
diagnostics to troubleshoot the malfunction.
A remote access alarm notification can be set up in one or both of the following
configurations:
Through an external modem (Port C)
Through the alarm relay via the cross-connect field (female amphenol)
If Port C is connected to a modem, and the alarm relay connected to the switch
via the cross-connect field, the remote service center will receive redundant
alarms from both the modem and the switch. Alternatively, you can configure the
cross-connect field to activate a local alarm device, such as a warning light or
buzzer, instead of sending the alarm to a remote location. When this
configuration is combined with a remote connection via the modem, the system
can alert both the local administrator and the remote service center.
