The KNX interface module EVO-KNX is a KNX gateway for the Paradox EVO alarm systems. It enables bidirectional communication with the alarm system using the RS232 communication module (PRT3) from Paradox.

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 Paradox EVO alarm systems
  • Up to 30 PGM status
  • Up to 96 zone status
  • Control up to 16 virtual inputs
  • 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
  • Galvanic insulation from the KNX bus

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.
