What Does Zone Damper Fault Mean? If a damper is closed or open but provides limited airflow, there is a fault in the damper zone. Equipment including, but not limited to, fans, ducts, automatic dampers and balance dampers, shall be suitable for its intended use, suitable for the probable exposure temperatures that the rational analysis indicates and as approved by the fire code official. The dampers may either be motorized, or of the gravity type. Besides the damper test required by NFPA 105, NFPA 72 requires an annual test of the spot-type smoke detector or duct detector that activates the smoke damper. It can also occur while attempting to pair the. A zone control system like this uses levers, which are located outside of the air vents, to regulate it. It determines the location from which the air blows out and if it fails, then it will affect the performance of your car. A zone damper (also known as a Volume Control Damper or VCD) is a specific type of damper used to control the flow of air in an HVAC heating or cooling system. actuator will hold the damper position. Connect Zone Damper Actuators (CZDA) to the zone ports using the RJ11 cables as shown. Do not locate where it will be accessible to children. 2 Mean Oscillation Frequency of Each Zone By Disconnecting Lines in Zone 269 E. 3 Mean Oscillation Frequency of Each Zone By Disconnecting Lines in Zone 369 E. zone damper would have a one-inch gap at the end of the frame once it is installed without a ductboard spacer. The damper is made up of a cylinder filled with silicone oil and piston heads. D and LCD Displays. This is a safety mechanism to protect the ductwork and the AC unit. Zone Damper Configuration.
