Temperature alarm

A temperature alarm for use with equipment of the type having a housing with an external display panel and a user-inaccessible region therein, the alarm comprising:

• a power source;
• a temperature-sensitive element, coupled to the power source, for providing a temperature signal when the temperature at said element is past a chosen value;
• alarm means, coupled to the temperature-sensitive element, for providing an audible alarm when the temperature-sensitive element provides the temperature signal;
• first visual indicator means, coupled to the temperature-sensitive element, for providing the user a visual indication at the display panel that the temperature is past the chosen value;
• a user-actuated alarm disable means at the display panel, coupled to the alarm means, for selectively temporarily disabling the alarm means for a period of time and thereafter re-enabling said alarm means;
• and
• a second visual indicator means, housed within the housing at the user-inaccessible region, coupled to the temperature-sensitive element and the power source, for continuously providing a second visual indication once the temperature-sensitive element has provided the temperature signal, the second visual indicator means including a user-actuated reset means for resetting the second visual indicator means so to halt the provision of the second visual indication after the temperature-sensitive element is no longer providing the temperature signal;
• the visual indication provided by the first and second visual indicator means being independent of whether the alarm means is selectively temporarily disabled by the user-activated alarm disable means.
