1. The man just wants schematics so that he can experiment on some old
boards.
2. He stated that he has been previously employed repairing fire alarm
systems.

He may be qualified to do board level repairs, or he may not. If he is,
he'll do it as well as anyone at the "factory". If he wants to assume
liability, how is that any skin off our noses?
