THE PROBLEM: to keep the general school population from using the elevator, a security lock had been installed. This student's disability prevented him from using the key to that lock. He was thus prevented from using the elevator.
THE SOLUTION: A battery operated radio remote switch was installed to bypass both the security switch and the call button. Pushing "on" on his remote ,mounted on his wheelchair, called the evevator and opened the door. A further advantage was that the door stayed open until he was safely inside and pushed his remote "off" button.
