Fenwal 12-E27121-000-05 Detect-A-Fire 225 °F

Fenwal 12-E27121-000-05 The Detect-A-Fire 225F is a self-contained, automated device for detecting and responding to overheating in various HVAC systems. This adaptable device has a pre-set trigger temperature of 225°F (107°C) and works on the "close on rise" principle, which means it activates when the ambient temperature rapidly rises over its threshold. When the Fenwal unit reaches this critical value, it either sounds an alert or, depending on the system design, engages fire suppression mechanisms immediately. The Detect-A-Fire 225F is commonly used in applications such as air handling equipment, fan coil units, and ducting and provides various benefits. Its compact dimensions and sturdy construction make it simple to install in a variety of HVAC systems. Additionally, its pre-set temperature removes the need for manual calibration, making maintenance easier.
