A guide on sensor activity monitoring in Alarm.com is linked below, with a table of common signals and any special considerations.

There is no concept of a temporary “test drive” mode in Alarm.com regarding that activity monitoring to eliminate delays. There are other potential things such as cellular latency which can influence testing results in the app when opening and closing sensors to test after installation. The best way to verify their functionality is locally there on the panel, using status and chimes, because the panel is the direct point of contact for that sensor.
