Alarm Port
The alarm port on the rear panel uses a standard DB-15 connector that provides a
connection for a Telco dry alarm relay cable. In a telecommunications environment,
use this port to connect to the central office alarming system. The alarm port relay
contacts are rated for 100V, 0.2A maximum.
Each alarm has a corresponding alarm LED on the front panel:
■
ALARM0 and the Critical LED
■
ALARM1 and the Major LED
■
ALARM2 and the Minor LED
■
ALARM3 and the User LED
