Fire receiver in fire alarm system

摘要

A fire receiver enables a fire alarm system to be reliably set up while the work for installing the fire alarm system is simplified, even if an IC card storing necessary data cannot be prepared or even at a time when the operation of connecting all terminal devices to the fire receiver is not completed. When a connection of the IC card to a card reader is detected when power supply to the fire receiver is turned on, data stored in the IC card is fetched and the terminal devices are operated on the basis of the fetched data. When no connection of the IC card to the card reader is detected when the power supply is turned on, predetermined data is fetched from the terminal devices by polling the terminal devices, and the terminal devices are operated by the data fetched by polling.
