Follow these steps in order. Keep the alarm panel configuration and the ETS project available during commissioning.
Prepare the installation
Paradox EVO or EVOHD alarm panel, PRT3 RS232 module, external 12 VDC supply and KNX bus. Have the matching ETS application and a valid alarm user code ready.
Connect and power the gateway
Connect the KNX bus, the 12 VDC supply and the supplied DB9 cable between PRT3 and EVO-KNX. The alarm panel AUX supply may power the gateway. See Hardware and compatibility.
Configure the PRT3
Enable its serial port, set 9600 baud, Home Automation and ASCII protocol. Enable required areas, zones, virtual inputs and PGM reporting; select all Report Options 1 and 2. See Alarm system setup.
Configure the KNX device in ETS
Assign an unused physical address. Enter the valid user code and its length; enable only supported functions. Select zone count and offset, area count, area mapping and scene numbers. See ETS commissioning and ETS parameter reference.
Link group addresses and download
Assign a group address to each required object. Press the programming button to enter KNX programming mode and perform a full download for first commissioning. See ETS commissioning.
Validate status and control
In ETS Group Monitor, read Module status (0 for normal operation) and Firmware. Compare enabled zone and area statuses with the panel; check configured control commands and scenes. See Group addresses and validation.
Commissioning is complete when
The alarm-system connection operates, the firmware can be read on KNX and the configured status, control and scene objects respond as expected.
