Summary:To provide an automatic fire alarm system which can easily grasp that sound of a sub-receiver has been stopped in a fire receiver, in addition to being able to temporarily and preferentially stop the sound of the sub-receiver according to a situation at a place where the sub-receiver is installed.SOLUTION: A sub-receiver 9 does not perform a sound alarm output when a predetermined operation different from a normal ON operation in a sound stop operation unit is performed; and alternatively, a sound alarm output is stopped and a sub-receiver sound stop signal for indicating a sound alarm output stop state is transmitted to a fire receiver 10; and the fire receiver receives the sub-receiver sound stop signal and performs such a display output control which indicates that the sub-receiver is in the sound alarm output stop state on an LCD screen 500 and/or a sub-receiver sound stop lamp 55.SELECTED DRAWING: Figure 1 【課題】副受信機が設置された場所の現場状況に応じて一時的かつ優先的に副受信機の音響停止を行うことができるとともに、火災受信機において、副受信機の音響停止がなされていることが容易に把握することができる自動火災報知設備を提供する。【解決手段】副受信機９は、音響停止操作部における通常のＯＮ操作と異なる所定操作がなされると、音響警報出力を行わない、または音響警報出力を停止するとともに音響警報出力停止状態を示す副受信機音響停止信号を火災受信機１０に送信し、火災受信機は、副受信機音響停止信号を受信して、ＬＣＤ画面５００および／または副受信機音響停止灯５５に副受信機が音響警報出力停止状態であることを示す表示出力制御を行う。【選択図】図１
