3.5 Alarm Contacts for monitoring internal power, and Software Traps
The Alarm Contacts feature, standard on Magnum 6K8-Series's, provides
two Form C Normally Closed (NC) contacts to which the user can attach two sets of
status monitoring wires at the green terminal block. When this option is present, the
terminal block for Alarm Contacts is part of the Power Input panel in the Magnum 6K8-
's case. The AC or DC power input connection is in the same panel. A manual On-Off
Switch for power to the unit is not available on 6K8- units with the Alarm Contacts
option, as these two features occupy the same space in the case.
The first NC Alarm Contact (top position) is a "Software Alarm", operated
by user settings in the MNS-6K software. The user can disable the Software Alarm
feature with a software configuration command if desired. When
the Software Alarm is enabled, the Form C Normally Closed
(NC) contact is held close during normal software operation. A
user-defined software malfunction, such as an SNMP Trap or a
Software Security violation or an S-Ring Fault, causes the contact
to open and thus trigger an alarm in the user's monitoring system
The second (bottom position) NC Alarm Contact is
held close when there is power on the main board inside of the
6K8-. This provides a "Hardware Alarm" because the NC
contacts will open when internal power is lost, either from an
external power down condition or by the failure of the power
supply inside of the Magnum 6K8- Switch. Useful info. about Alarm contacts:
1. There is four terminal block (1,2,3,4) provided next to AC/DC power supply
2. The top two pins (1,2) are software operated
3. The bottom two pins (3,4) are hardware operated
4. By default it is NC (normally closed)
5. The software operation needs to be enabled and set to get the Alarm traps. For detail
information about the Software Alarm and software control of SNMP alarm traps, please
reference the Magnum MNS-6K Software User Manual. (Chapter 19th).
The Alarm Contact is on the front left area (next to the DC power source) of
the Magnum 6K8-Series unit and is green in color as shown in the picture.
