That the sun is causing a problem only when the AC is off sounds
improbable.  Do you have a log of the times when the alarm goes off?
If it was related to sunlight the problem would tend to happen around
the same time of day.

It could just be a faulty detector.  The simplest solution is to turn
that one unit off but that would leave a hole in your protection.
Instead, ask the tech to move the unit (or do so yourself; it's not
rocket science) to a location where sunlight and AC vents can't affect
it.  If it continues to false, replace it.

No can do.  I'm using someone else's PC.
