I don't know much about these and the only testing I was able to do was to see if the non motion alarm worked and it does.
I believe they could still be used for training, or other alarms or noise makers.
They are powered by 9v battery, which is not included with them.
The small white label on the side is the year it was made.

The sound is a little distorted.
