IPS42 Internal Power Supply Installation and User Guide (11/09)

3.3 Hardware operated Alarm Contact

The two screw Alarm Contacts feature, standard on Magnum IPS42-Series, provides Normally Closed (NC) contacts to which the user can attach one set of status monitoring wires at the green terminal block.

The NC Alarm Contact is held close when there is power on the main board inside of the IPS42. This provides a “Hardware operated 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 IPS42-Series Power Supply.
