PROBLEM TO BE SOLVED: To provide an alarm device for a refrigerated showcase in which a temperature can be confirmed at a remote location and its operation is reliably carried out when it is required to issue an alarm. SOLUTION: A temperature of a freezing showcase is detected by a temperature sensor, its detected temperature is concentrically monitored by an alarm device 1 for a refrigerating showcase placed at a remote location. The alarm device 1 for the refrigerating showcase is comprised of a temperature signal inputting section 2 for inputting a temperature signal of the refrigerating showcase, an upper limit temperature setting section 3 for setting an upper limit temperature of the refrigerating showcase, an alarm outputting section 4 for outputting an alarm to an external part when the detected temperature exceeds a temperature set by the upper limit temperature setting section 3, an alarm delay section 5 for delaying the alarm output of the alarm outputting section 4 by an optional time, a displaying section 6 for displaying either the set information or the monitoring information and a control section 7 for controlling the alarm device 1 for the refrigerated showcase. |
