Reading from the above it would seem that the alarm system is totally

the 302 programming is smart enough to allow testing while I am
standing still.

The 302 gear warning is fully functional on ground at zero airspeed
and ground speed. It will also sound when the 302 is powered up with
brakes unlocked even if the gear is down and locked. To cancel it
press the knob or lock the brakes.

My gear warning sounds nearly every time I apply power after rigging
the glider as the brakes have to be unlocked for assembly.

For standard class glider using airbrakes for roll control on takeoff
the warning may sound briefly before it becomes time to lock the
brakes.

As has been mention by others, the brake switch should detect the
difference between "closed and locked" and "closed". Unless the gear
won't stay down if not locked, the gear switch should detect the
difference between "down" and "down and locked". (28 gear floats
halfway if not locked up or down so detecting full forward is
sufficient)
