A sauna alarm is a heat-resistant emergency button placed inside a sauna, designed to allow users to call for help in case of fainting or danger. This system alerts external personnel or household members with audible and visual signals, enabling a quick response.

While not legally mandatory for home saunas, an alarm system is highly recommended for user safety. It is crucial for individuals using the sauna alone or those with health conditions, as it provides a vital way to alert others in case of an emergency. This ensures prompt assistance can be provided in unexpected situations.

A sauna alarm should be installed at a low position, approximately 40-50 centimeters from the floor, allowing even a fallen or unconscious person to easily reach and press it. This maximizes accessibility in emergencies and ensures it is a safe distance from the sauna heater.

When the user presses the button, a wired or wireless signal is transmitted to a receiver unit outside the sauna. This unit, typically located in an area like a reception or hallway, emits a strong audible and/or visual alert, immediately notifying staff or household members of the emergency. This allows for quick intervention to assist the person inside.
