The KNX interface parameters are defined in the “Parameters” tab of the device in the ETS project.

Zone
Depending on the general parameter “Number of zones”, up to 96 zones are listed in the group objects. The status of each zone from the alarm system can be monitored by a group object.
Remember that zone statuses are only reported when the system is armed, in night mode, or when individual devices are set to Always Active in the AJAX app (see Zone Reporting Behaviour under Configuring the alarm system).
Area
Depending on the general parameter “Number of areas”, up to 4 areas are listed in the group objects. Each area can be controlled using 3 group objects: Arm, Partial Arm, and Disarm.
Control Objects
| Control Object | Value ON | Value OFF |
|---|---|---|
| Arm (switch) | Arm | Disarm |
| Partial arm (switch) | Partial Arm (activates Night Mode for complete Hub) | Disable Night Mode |
| Disarm (trigger) | Disarm | Disarm |
For each area, a configuration tab is made visible in ETS. Areas are configured for AJAX groups 1–4 by default, but the “Area mapping” parameter allows covering groups 5–8 instead.
Scene Assignment per Area Status
A KNX scene can be assigned to each area status. The scene number is recalled each time the corresponding status becomes active (ON). Leave the scene number at 0 to disable scene control for that status.
| Status | Scene Range |
|---|---|
| Disarmed | 0–64 |
| Entry (NOT USED) | 0–64 |
| Exit (NOT USED) | 0–64 |
| Armed | 0–64 |
| Partial armed | 0–64 |
| Fire alarm | 0–64 |
| Siren ON (NOT USED) | 0–64 |
| Panic alarm (Silent alarm) | 0–64 |
| Intrusion alarm | 0–64 |
Intrusion Alarm Behaviour
The Intrusion Alarm status is activated when the partition is armed (either partial or total) and a detector from that group sends an alarm event. The Intrusion Alarm is automatically reset when the partition is disarmed.
