The KNX interface module NXG-KNX is a KNX gateway for the Interlogix ultraSync alarm systems (NetworXConnect, xGen and ZeroWire) from UTC Fire & Security. It enables bidirectional communication with the alarm system over Ethernet.

It allows integrators to take advantage of a fully integrated alarm system including KNX scenarios, automatic lighting using the motion detectors, arming or monitoring the system using a KNX visualization.

Main features:

  • KNX Interface for Interlogix ultraSync (NetworXConnect, xGen and ZeroWire)
  • Up to 96 zone status
  • Control up to 4 areas (arm/partial/disarm)
  • 9 statuses per area (alarm, entry, exit, fire,…)
  • Recall of KNX scenes for each status
  • Battery and AC Failure monitoring
  • Connected to the alarm system over Ethernet
  • Galvanic insulation from the KNX bus
  • DIN rail mounted
  • Auxiliary power supply 12-30VDC

By default, zone status is configured for zone 1 to 96 of the alarm system. A general parameter allows to change for zone 97 to 192. Having then the possibility to use two gateways in the same installation to cover the 192 zones of the alarm system.

In the same way, areas are configured for areas 1 to 4 of the alarm system but a parameter allows to change the area number to cover the areas 5 to 8 if required.

Requirements

Interlogix ultraSync alarm system (NetworXConnect, xGen or ZeroWire), 12-30 VDC auxiliary supply, KNX bus and Ethernet connection.

Use ETS with the appropriate Elausys alarm gateway application to assign the physical address, set parameters and link group addresses.

Operating limits

PG control, PG status, virtual inputs and Device Options are not available. The Network LED confirms the physical link; the Connected LED confirms alarm-system communication.
