Difference between sensor group 38 (water) and 25 (water non-reporting)?

Would tripping group 38 actually have police or fire showing up to the house?

If set to group 25, would I still get the siren or alerted if I’m out of the house?

Thanks.

No, a water alarm indicates a leak at the home and would not result in calls to emergency authorities.

You can set notifications in Alarm.com for sensor activity on that zone. It would not generate any local siren.
