Interlogix NX-584E Home Automation Module

The Interlogix NX-584E is a low cost add-on module that fits neatly into any NetworX family system enclosure and provides a standard RS-232 bi-directional DB-9 connector for connection to a home automation host system. A simple three-wire connection to the main control is all that is required to fully integrate this card into the system.

The NX-584E has several levels of security that can be programmed at the time of installation to allow as much or as little security system information to be passed to the host system. It can also be set to limit the commands that will be accepted from the host system to prevent unauthorized attempts to override the security system status.

The unit can be easily configured for communication in an ASCII or binary protocol. A selectable baud rate can be set from 600 baud to 76.8k baud with hardware RTS and CTS handshaking. The ASCII implementation is easy to use and debug with standard programming tools while the binary version is a more efficient for method for transferring information between the two systems. The system integrator can select any number of events or conditions to cause the NX-584E to send the relevant information to the host without polling. This allows for a faster response to activity than polling alone can provide.

All security system information can be requested at anytime if enabled to do so by the installer. This is useful at system initialization and at periodic intervals to keep the two systems in sync without worrying about missing any transitional event. This information is organized as System, Partition, Zones and Outputs. System information will contain such information as power status, phone line condition, module troubles, and other system wide condition. Partition information includes readiness of all zones assigned, armed state, entry / exit delays, last user number, alarm condition and many other conditions within a specific partition. Zone information includes faults, alarm memory, bypasses, troubles, tampers, low batteries, missing and partition assignments. Output messages include commands that can be passed to or from devices in X-10 compatible format.
