The user-settable miscellaneous discrete interface allows an operations system (OS) to control and monitor equipment collocated with Alcatel-Lucent 1665 DMX through a set of input and output contact closures. Miscellaneous discrete environmental inputs can monitor conditions like open doors or high temperature, miscellaneous discrete outputs control equipment such as fans and generators. The status of the miscellaneous discrete environmental inputs can be queried on demand via the WaveStar® CIT. Alcatel-Lucent 1665 DMX collects miscellaneous discrete alarms and automatically sends them to the operations system (OS).
Any external customer equipment to be monitored by Alcatel-Lucent 1665 DMX must provide the electrical equivalent of a contact closure across the corresponding environmental input wiring pairs. The contact closure must be capable of passing at least 10 mA of drive current.
The power source to enable the control of external customer equipment may have a voltage range from a minimum of 3V to a maximum of 72V. Alcatel-Lucent 1665 DMX provides a unidirectional opto-isolator connection across each corresponding control output wiring pair. The load current across each control output wiring pair must be limited by the external customer equipment and must not exceed 35 mA.
For detailed wiring information, see the Alcatel-Lucent 1665 Data Multiplexer (DMX) Installation Manual, 365-372-304.
