Title:
DOOR UNLOCKING SYSTEM WITH DISASTER PREVENTION ANNOUNCEMENT AT EARTHQUAKE
Document Type and Number:
Japanese Patent JPH08246727
Kind Code:
A
Abstract:

PURPOSE: To improve safety and prevent a malfunction by providing a voice guide device operated via the combination of two signals of an earthquake sensor and a human detecting device on an electric unlocking device, and automatically making guidance and unlocking when an earthquake occurs.

CONSTITUTION: A P-wave earthquake sensor 5, a voice guiding device 6, and a human detecting device 1 or a human intention confirming device (e.g. a push button) are installed on an electric door unlocking device 7. When the sensor 5 detects a shake of a fixed level or above, the voice guiding device 6 is operated, and an announcement such as an advance notice of an earthquake and an instruction to put out flames is made before a strong shake of the S- wave arrives. When the human detecting device 1 detects a human in a building, it unlocks an exit door with an announcement for unlocking. When the human intention confirming device such as the push button is provided, unlocking is made after the action on the push button is confirmed. Safety is improved, and a malfunction can be prevented.
