ABSTRACT:
A detention cell locking system affording improved securement and reliability in the locking network of multiple detention cell doors. Mechanical actuation linkages are interconnected for motion responsive to either select manual, mechanical, or electrical signals actuating a DC motor drive. The locking mechanism incorporates an elongate toggle plate mounted to a carriage plate and a pair of cell door support rollers forming part of a mechanical locking system. The toggle plate assembly on the carriage plate permits a turning moment to be generated for lost motion actuation which effects locking and unlocking of the detention cell doors. A control network determines the length of time that the DC motor is electrically actuated and disengages the power to the motor during manual mechanical actuation.
