What is the function of motorized damper?
Essentially, the damper regulates the flow of air inside the air handling equipment, influencing your overall health in the long term. A functioning motorized damper allows for temperature within a room to be controlled by you, regulating the flow of air in your home.
How are Motorized dampers controlled?
The dampers are wired to a main control panel to which each zone’s thermostat is also wired. The main control panel can then maintain each zone’s set temperature by controlling the opening and closing of each damper.
Which NFPA standard defines how fire dampers are to be inspected?
NFPA 80
NFPA 80(10), Sec. 19.4. 1 requires that each damper be tested and inspected 1 year after installation.
What is Motorized fire damper?
Motorized Fire Damper prevents the passage of flame from one side of a fire rated separation to the other and will be functioning with the help of actuators with either an electric or pneumatic actuator. They are controlled by heat detector signal, fire alarm or some other building control system.
What is suspension damper?
A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated.
What is damping and why are dampers used for?
A damper is a valve or plate that stops or regulates the flow of air inside a duct, chimney, VAV box, air handler, or other air-handling equipment. A damper may be used to cut off central air conditioning (heating or cooling) to an unused room, or to regulate it for room-by-room temperature and climate control.
What are automatic dampers?
Automatic dampers are used to regulate airflow constantly and are operated by electric or pneumatic motors, in turn controlled by a thermostat or building automation system.
What is the difference between motorized damper and smoke damper?
Both Fire and Smoke Damper (FSD) Both a heat detector and a smoke detector are used to close the damper. Motor Shut-down – If the damper is automatically reset with a motor, the motor loses power and shuts the damper when either the duct smoke detector or when the duct heat detector is activated with smoke or heat.
What is a combination fire smoke damper?
A combination fire/smoke damper is used when a barrier is both rated for fire resistance as well as designed to restrict the transfer of smoke and will meet both the fire damper and smoke damper requirements.
What is a smoke damper or smoke barrier?
A smoke barrier can be a wall, floor, or ceiling. A smoke damper prevents the spread of smoke throughout a building, keeping employees and residents safe from smoke inhalation and your property safe from smoke damage. A smoke damper is installed throughout your HVAC system, where preventing smoke leakage and spread is crucial.
What is the function of a motorized damper?
Many folks do not learn the function of the motorized damper until this part breaks. What is the purpose of a motorized damper? Essentially, the damper regulates the flow of air inside the air handling equipment, influencing your overall health in the long term.

What is a dynamic fire damper?
A dynamic fire damper is installed in vertical barriers within the HVAC system. This means that if there is a fire, the HVAC system fans will continue to circulate air, but a dynamic fire damper will shut due to its spring-loaded design that forces the fire damper to close because of air pressure.
