Burglar alarm and door chime

Abstract

A battery operated combination burglar alarm and door chime is mounted to the inside of a door. The alarm mode is capable of being armed from either side of the door. A dead bolt slide cooperates with a plate fastened to the door frame to manually arm the device from the inside with the door closed. A plunger slide also cooperates with the plate fastened to the door frame and a mode selection switch to effect either a chime mode or a delayed alarm mode when the door is opened. The delayed alarm mode being activated with the door open to permit pre-arming the device followed by automatic arming of the device when the door is closed. Depending upon the alarm mode of operation selected, unauthorized opening of the door can either lock the door and instantaneously sound an alarm or sound an alarm after a predetermined time when the door is opened. A combination switch deactivates the alarm and chime modes and another switch can alter the combination. An optional, independently powered smoke detector may be integrated with the above.
