けたことを特徴とする侵入者警報システム。[Claims for Utility Model Registration] A plurality of human body detectors are connected to a power supply line drawn out from a receiver, and an alarm is provided in each of the human body detectors to be turned off when a human body is detected in a signal line from the receiver. Each of the human body detectors is formed by connecting normally closed relay contacts of a relay in series, and each of the human body detectors includes a detection circuit for detecting an intruder, a comparison circuit that outputs an output when the output of the detection circuit is equal to or higher than a predetermined level, and the comparison circuit. In the intruder alarm system, the intruder alarm system is equipped with a first alarm driving circuit that operates with a comparison output of the detector to light an operation indicator light and activate the alarm relay, wherein the receiver is provided with a power supply for each of the human body detectors. A power supply adjustment means for adjusting the state is provided, and each of the human body detectors includes a holding circuit for holding the comparison output of the comparison circuit, and a power supply adjustment means for the receiver is provided in a state in which the holding output of the holding circuit is obtained. An intruder alarm system comprising: a second alarm drive circuit that cancels a normal detection function and lights up the operation indicator light or a dedicated operation indicator when power adjustment by the adjustment means is detected. .
