を特徴とするセキユリテイコントローラ。 Alarm signals such as audio signals and intermittent signals output from the controller body are amplified by an amplifier, the amplified signals output from the amplifier are input to the speaker via speaker wiring, and the alarm is emitted from the speaker. The security controller is characterized by being provided with a noise generation prevention means that turns on the power supply or output of the amplifier using a switch means that is turned on by a sound output timing signal that is output from the controller body in synchronization with the output of an alarm signal. security controller.
