Power saving system which assures room security
First Claim
1. A power saving system for conserving energy consumption by electric loads in a room having a door with a locking system, and which system also assures room security, comprising:
- closure switch means for coupling to the door and producing a control signal only throughout the time the door is opened;
lock switch means for coupling to the door locking system and producing a control signal only throughout the time of proper locking of the door, both said control signals being the same;
control means associated with an electric load in the room, andwire means coupling said closure switch means and said lock switch means in parallel to said control means,said control means comprising timing means responsive to the termination of a control signal on said wire means for producing a control signal for a preset limited interval of time, and for ceasing operations upon the presence of a control signal on said wire means, and control switch means responsive to any of the aforesaid control signals for controlling the energization of the electric load during the time that a control signal is present.

Abstract
A power saving unit which also assures room security by requiring a door to be properly locked before particular electric loads will be energized. The system includes switches connected to the door providing indication of whether the door is open, closed, or locked. A control circuit controls the energization of a particular electric load connected to the system. A suitable gate responds to the door being locked or opened to activate the control circuit for maintaining the load energized. It responds to the door being closed but unlocked to keep the load energized for a predetermined interval of time after which the load will be switched off. Suitable indicator lights are provided to remind the guest to lock his door in order to retain the loads energized.
