The HD-11 Hydrogen Gas Detector is a low-voltage dual relay hydrogen gas detector. The unit is designed to work with control panel or other building management equipment to help monitor levels of hydrogen gas in a room or facility where hydrogen gas may be present, such as areas where forklifts, backup power supplies, or golf cart battery charging stations are located. The HD-11 is not designed to detect smoke, fire or carbon monoxide.

The three part plastic case allows the HD-11 to be either surface mounted, or installed over a four-inch square or double gang electrical box.
