Claims (1)

[Scope of claim for utility model registration] (1) In a disaster prevention receiver that generates an alarm sound in response to an alarm input signal from a sensor placed in a warning area, the alarm sound generated by the alarm input signal is stopped or an alarm is issued. An operating switch that returns to the re-sounding state, and a re-sounding system that detects the operation time of the operating switch, simply stops sounding the alarm, and then sounds the alarm in response to an alarm input signal that is input thereafter. There is a lock function that stops the sound of the alarm sound and also stops sounding in response to subsequent alarm input signals, and a lock function that detects the operation time of the above operation switch and cancels the above lock function and starts the alarm sound. 1. An alarm control device for a disaster prevention receiver, comprising: a re-sound return function that enables re-sounding; and a determining means that determines whether the alarm can be re-sounded and controls the alarm according to the operation time of an operation switch. (2) The disaster prevention receiver as set forth in claim 1 of the utility model registration claim, characterized in that it is provided with a display means that optically displays that the lock is in the locked state when the lock function is operated by the determination means. Alarm control device. (3) Alarms are divided into main audible alarms that issue warnings over the entire warning area and district audible alarms that issue alerts only in specific areas, and when the district audible alarm side is in the lock state of the alarm with the lock function, The alarm control device for a disaster prevention receiver according to claim 1, wherein a lock function is not activated on the main acoustic alarm side. (4) Warnings are divided into main sound warnings that issue warnings over the entire warning area and district sound warnings that issue warnings only in specific areas, and each of the main sound warnings and district sound warnings is locked by the above-mentioned determination means.
