Securing Expensive Lecture Hall Equipment
Customer Problem
A commercial furniture systems manufacturer needed a solution to secure computer desks located in large lecture halls. The manufacturer’s customer wanted to allow the lecturer to lock and unlock the desks during the lecture as well as secure the desks after the class period with a small key-fob-style remote control. Because the desk locks would be powered by a small power supply, the manufacturer needed a complete system that drew minimal power.
The TLX Solution
TLX designed a system with 20 to 30 solenoids powered by a single low-voltage power supply, with the locking mechanisms actuated by pull-type solenoids. When energized, the solenoid’s armature would pull in to unlock the desks. When power was removed, the armature would return to the home position and maintain the locked position without drawing any current. The system was designed to be controlled by a key fob from anywhere inside the lecture hall.
