TOW WAY OF WIRELESS AUTO FIRE EXTINGUISHING EQUPMENT

摘要

PURPOSE: An interactive wireless automatic fire extinguishing device is provided to report the state of an automatic fire extinguisher to a user using full duplex communication through an indoor wireless access device and a telephone line. CONSTITUTION: A communication microcomputer(11) decodes encoded data offered from a receiving unit(RXc) with an embedded key. The communication microcomputer distinguishes decoded data by a communication controller identification code and state report data. If the communication controller identification code is equal to a magnetic code registered in a memory, the communication microcomputer selects a voice message corresponding to decoded report data in a voice chip(15). The communication microcomputer transmits the voice message to a telephone line and a voice output unit(17).
