2.6 Alarm Contact for Monitoring Internal Power
The Alarm Contacts feature, standard on EKI-9500 Series, provides one Form Nor-
mally Closed (NC) contact to which the user can attach one set of status monitoring
wires at the green terminal block.
The NC Alarm Contact is held closed when there is power on the mainboard inside of
the switch. This provides a “Hardware Alarm” (labeled H/W) because the NC con-
tacts will open when internal power is lost, either from an external power down condi-
tion or by the failure of the power supply inside of the EKI-9500 Series.
