PROBLEM TO BE SOLVED: To provide an alarm for correcting the deviation of transmission/reception timings while suppressing a current consumption amount. SOLUTION: This alarm is provided with: a temperature detection circuit 10 which detects a temperature near a clock generator 12; and a storage element 13 for storing an initialization count number (131) as a count number per the unit time of a clock signal, an initialization temperature 132 corresponding to the initialization count number (131) and temperature characteristic information 133 of the clock generator 12. A transmission/reception part 5 transmits a status signal while repeating a transmission time and a transmission quiescent time in every transmission cycle to the other equipment, and receives the status signal transmitted from the other equipment in every intermittent reception cycle, and a control circuit 1 corrects the transmission/reception timing of the transmission/reception part 5 according to the result of comparison of the detection temperature of the temperature detection circuit 10 and the initialization temperature 132.
