The “zone trigger” ASCII command only causes a momentary open state and violated status of the zone. Having a zone definition of “non-alarm” will not cause an alarm. The ‘non-alarm” zone can be used in an automation rule to trigger an event.
In order to verify that the “zone trigger” ASCII command actually triggered, an example automation rule like this could be used:
Whenever Zone (non-alarm) (Zn 55) Becomes Not Secure
Then turn Relay (Out 3) On for 10 seconds.
