Chapter2121 – Miscellaneous CommandsImproving productivity and manageabilityhere are several features built into the Magnum 6K family of switches which help withthe overall productivity and manageability of the switch. These items are examinedindividually in this chapter.TAlarm RelaysIn a wiring closet, it would be helpful if there was a visual indication for faults on components onthe network. Normally, these would be performed by LED’s. While the Magnum 6K family ofswitches has the necessary LED’s to provide the information needed, it also has a provision fortripping or activating an external relay to electrically trigger any circuit desired. These could be anindicator light, a flashing strobe light, an audible alarm or any other such devices.The Magnum 6K family of switches has a software (optional) controlled relay contact that can beuse to report alarm conditions. The relay is held closed (connection) in normal circumstances andwill go to open position during alarm conditions.Two types of alarm signals are defined in the alarm system.• SUSTAINED• MOMENTARYThe SUSTAINED mode is used to report a continuing error condition. The MOMENTARYmode is used to report a single event.The following pre-defined events are currently supported on the MNS-6K and the relay whichcan be triggered by software:256
