3.5Alarm Contacts for monitoring internal power, and Software Traps

The Alarm Contacts feature, standard on Magnum 6KQE’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 6KQE case. The DC power input connection is in the same panel.

The first NC Alarm Contact (top position, switch vertically mounted) 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 triggers an alarm in the user’s monitoring system

The second NC Alarm Contact is held closed when there is power on the main board inside of the Switch. 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 Switch.

Useful info. about Alarm contacts:

1.There are four terminal blocks (1,2,3,4) provided next to the DC power supply

2.The left two pins (1,2) are hardware operated

3.The right two pins (3,4) are software operated

4.These are both NC (normally closed) relays

5.The switch’s software operation needs to be enabled and set to get the Alarm traps. For detailed information about the Software Alarm and software control of SNMP alarm traps, please reference the Magnum MNS-6K Software User Manual.

The Alarm Contacts are on the front left area (next to the DC power source) of the Magnum 6KQE unit and are green in color as shown in the picture.
