Issue
Request to exit motion sensor seems to be causing nuisance alarms.
Environment
CyberStation, ACX family, AC1 family, REX motion sensor
Cause
Even though the exit request variable is "On" in the door object, if the door opens and closes more than once, a forced entry alarm is created. This causes issues when the REX motion never turns off and multiple users exit the door.
Resolution
In Continuum controller firmware once the door is closed and locked a change of state of the REX input is required to keep the alarm shunted.
To simulate this, trigger the REX motion detector and then open the door while it is unlocked. The door relocks 1 second after opening. If the door REX signal goes OFF and then ON again, the door unlocks. If, while the door is unlocked, the REX signal goes OFF and ON and OFF and ON the door can be opened and closed with no forced entry OR it can remain open and no door ajar will occur. The same is true if you do not check 'unlock on exit request' - it's just harder to test because you cannot watch the REX signal as easy as the unlock output.
The key to avoiding the nuisance forced entry alarms is to let the REX motion sensor cycle quickly - have it turn on and then off after 1/2 to 1 second. The forced entry alarm will be shunted until the door relocks. Then if there is still motion at the sensor the REX will come on again and the controller will continue to shunt the alarm.
