Abstract
A remotely controlled door and window locking device is provided with a plurality of deadbolts responsive to master control signals and positioned with respect to associated doors and windows so that when triggered to locked positions, all of the doors and windows connected to the system are locked. The device has retaining means preventing the movement of respective deadbolts associated with the doors and windows when the doors are left ajar or windows are left in other than a closed or predetermined open position, and display lights at a master control panel each one of which remains off when its associated door is ajar, or window is in other than a closed or predetermined open position.

A remotely controlled locking device comprising:
- a plurality of locking elements for locking a corresponding plurality of movable wall-opening barriers, each locking element having an individual lock-operating mechanism for selectively, reversibly driving said corresponding locking element into a locked or an unlocked position in response to "lock" or "unlock" control signals, respectively;
- master control means remotely connected to each lock-operating mechanism for selectively providing to the latter said "lock" or "unlock" control signals;
- display means connected to each lock-operating mechanism responsive to the condition of each locking element, for displaying said condition of each locking element;
- local control means for rendering inoperative control signals provided by said master control means and for the provision of "unlock" control signals to associated lock-operating mechanisms;
- and
- manual override controls mechanically coupled to each locking element to allow manual movement of each locking element to a locked or an unlocked position.
