PROBLEM TO BE SOLVED: To provide an alarm in which even when the alarm is arranged at a high position above the head of a user, the user is able to easily perform its operation.SOLUTION: An alarm 1 includes: a sensor part 10 for detecting an alarm object which is generated in a monitoring area in a predetermined period; a CPU 21 for outputting an alarm signal when the detection result of the sensor part 10 exceeds a predetermined determination threshold; an alarm part 30 for issuing an alarm in response to an alarm signal to be output from the CPU 21; and a human sensor 45 for detecting a human body existing in a detection range DA. Then, when a human detection signal is output from the human sensor 45, the CPU 21 determines that any operation from a user has been performed, and executes a predetermined operation. For example, when the human detection signal is output from the human sensor 45 during the output of the alarm signal, the CPU 21 stops the output of the alarm signal. |
