Cannot silence an alarm when using the Custom Function set to Disarm
The custom function ‘Disarm’ will only disarm the area (or areas) selected in Custom Function programming.
Custom Functions can include up to six functions. When silencing alarms with a custom function, Function 1 must be Alarm Silence and must include the areas to silence the alarm.
In order to perform a Silence command and also Disarm, Function 2 would be Disarm and also include which areas to disarm.
