FIRE ALARM RECEIVER HAVING MAJOR ALARM STOP RELEASE FUNCTION

摘要

A fire receiver having an automatic stop function is provided to sound an alarm by automatically loosing a main alarm when a fire senses. A fire sensor(10-1~10-5) senses a fire occurrence of each region. A region circuit part(110-1~110-5) indicates a fire of a corresponding region if the fire is perceived with a fire sensor, and generates an occurrence signal. A main fire indication(LED2) indicates the fire occurrence according to the fire occurrence signal. A main alarm circuit(120) sounds the main alarm according to the fire occurrence signal, and stops the main alarm if the main alarm stop switch is pressed down. A region alarm circuit(130) sounds the region alarm according to the fire occurrence signal, and stops the region alarm if the region alarm stop switch is pressed down. A main alarm stop automatic pause circuit(140) automatically looses the main alarm stop of the main alarm circuit if the fire is perceived from each fire sensor.
