Cool or Kewl, it’s certainly ineffective.
If all that’s required by local code is the alarm, then simply capping the pan drain would have been sufficient…but I doubt it.
Here it has to drain to the outside, alarmed or not.

It looks like there is an overflow shut off switch at the front of the pan. Was it wired into the system? Many pans don’t have a drain if a shutoff switch is installed.
Otherwise, water hasn't started flowing up hill has it?

It’s the only unit and it’s in the attic. Thanks for all of your input. I wrote it up something like this:
The secondary drain pan of the unit is not plumbed to the outside. The secondary drain runs straight up for a couple of feet then stops (See picture). If the primary drain clogs then the secondary drain will become active and water may eventually overflow the top of the pan causing interior water damage to the structure. There appears to be an overflow shutoff switch installed near the top of the secondary drain pan rim. This device may shut off the A/C unit in the event of an overflow event. I recommend that the secondary drain line be routed to the exterior of the dwelling even with the presence of the overflow shutoff switch as these switches have been known to fail.

Aww com’on now. This HVAC installer was obviously a former plumber. Since it’s a drain it needs to be vented. That’s a mini- vent stack!
