Claims (1)

[Scope of utility model registration request] It has an abnormality detection transmitter including an intrusion detection transmitter that transmits an intrusion detection signal in response to the opening of a window, door, etc., a night mode, a daytime mode, and means for switching between these modes. In a security device equipped with a main unit that outputs an alarm in response to reception of all abnormality detection signals, and in response to reception of abnormality detection signals other than the above-mentioned intrusion detection signal during daytime mode, and automatically reports to a monitoring center, The base unit includes means for delaying automatic notification to the monitoring center for a predetermined period when receiving the intrusion detection signal during night mode, and an intrusion detection signal that is transmitted again from the intrusion detection transmitter during the delay time. A security device comprising: a means for stopping notification of an intrusion detection to a monitoring center after the delay time has elapsed and an alarm is received in response to reception of the security device.
