SECURITY SYSTEM WITH POWER SAVING FEATURE AND DEVICE
First Claim
1. A security system with power saving feature and device, comprising:
- an electromagnetic lock having an electric magnet with electromagnetic attraction and an iron plate arranged on a corresponding surface thereof;
a power supply circuit providing power for the electric magnet; and
a sensing module electrically connected to the electric magnet and detecting a signal cause by an environment change at which point the sensing module is configured to output a triggering signal to cause a full supply of the electric power from the power supply circuit to the electromagnetic lock;
wherein the sensing module is a G-sensor module and the G-sensor module includes;
a plate, an elastic member arranged on the plate, a G-sensor arranged on the elastic member and electrically connected to the power supply circuit, an abutment body arranged on the G-sensor and having a protrusion portion and a positioning flange at a periphery thereof, and a seat having an axial through hole for the abutment body to be axially telescoped therein and the telescopic abutment body driving the G-sensor to provide an upward elastic force for the abutment body by the elastic member;
the iron plate includes a spot-faced hole and locked on a door board from an inner side thereof by the spot-faced hole and a bolt assembly, and a spring mounted on the bolt assembly for having an elastic displacement space between the inner side of the iron plate and the door board;
a pressing face mounted on the iron plate and having a front side contacted with the abutment body of the G-sensor module;
whereby when the iron plate is adsorbed by the electric magnet, the abutment body of the G-sensor module is pressed by the pressing face to simultaneously drive the inward movement of the G-sensor and compress the elastic member;
at the same time, the electric magnet is in a low power attraction state;
when the abutment body of the G-sensor module is moved by an external action, the G-sensor is activated by the displacement of the elastic member to return to normal current supply and rapidly get into the normal lock state.

Abstract
The invention relates to a security system with power saving feature and device comprises an electric magnet and a corresponding iron plate. The electric magnet is connected to a G-sensor module and the iron plate has a pressing face to contact with the G-sensor module. When the door is opened, the electric magnet does not supply power; when the door is closed, the electric magnet with electromagnetic attraction attracts the iron plate and the pressing face presses the G-sensor module. That is, the electromagnetic lock usually stays in a low-energy attraction state; however, when the G-sensor module is triggered, the electromagnetic lock returns to a normal lock state for achieving power saving effect and control of the external force detection improvement.
