The S2-AHD-300 is an addressable fixed-temperature heat detector with a built-in isolator, designed to detect temperature rise in environments where smoke-producing substances may be present under normal conditions. When the ambient temperature reaches the alarm range of 54 °C to 70 °C, it reports a fire alarm to the control panel.
