Fire alarm receiver

Abstract

The fire alarm receiver database will be updated while maintaining the fire monitoring function. [Solution] The fire alarm receiver 10 includes a first memory where a database is deployed, a second memory where the database is deployed, a main microcontroller connected to one of the first and second memories and processing status information received from multiple terminal devices, and a switching means for switching the memory connected to the main microcontroller after the database has been updated and the updated database has been deployed to the memory of the first and second memories that is not connected to the main microcontroller.
