What is Msfd damper?
MSFD(Motorized smoke fire damper) is a damper which has an actuator to provide action upon control signal from the main fire control panel.it is used at all the outlet of smoke exhaust or fresh air mock up and works as close damper.
What is the use of Msfd?
MFSD are designed to be installed in HVAC ductwork at locations that are designated as fire barrier or fire & smoke barrier. It should not be installed in a smoke extraction ductwork for smoke extraction applications.
Where do you put a Motorized fire damper?
Location: Fire dampers are installed in or near the wall or floor, at the point of duct penetration, to retain the integrity and fire rating of a wall or floor whether it is a ducted or open-ple- num return application.
What is a fusible link fire damper?
Fusible Link: A temperature sensitive device that holds the damper components in the open position, which in turn, allows air to pass through. When the fusible link opens, it releases the damper components to close, and they will stay closed until a new fusible link is installed.

What is Msfd HVAC?
Motorized Fire and Smoke Dampers Our Smoke & Fire Dampers (MSFD) are designed to stop the spread of fire through ducts or walls in central air conditioning systems. OPTIMA Fire/Smoke Damper provides an automatic means of localizing area of fire in ventilation system with building management systems as option. FEATURES.
What is the difference between a fire damper and a smoke damper?
A fire damper closes once the duct temperature reaches a high enough level to melt a fusible link. A smoke damper closes upon the detection of smoke. It is UL leakage-rated to stop smoke in its tracks, which is a main difference from fire dampers.
How does a motorized fire damper work?
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 the difference between a radiation damper and a fire damper?
Fire dampers are intended for duct work penetrations entirely through a rated assembly. A ceiling radiation damper is intended for membrane penetrations of a rated horizontal assembly. Together, all the components work to maintain structural integrity during a fire for a certain period of time.
What temperature does a fusible link melt?
About fusible link’s The melting point of the alloy can be engineered to release at temperatures ranging from 135F/57C to 500F/260C. Our products comply with Underwriters Laboratories, Inc., Factory Mutual Research Corporation and NFPA Requirements.
What is the difference between smoke dampers and fire dampers?
What happens if you put a damper on a fireplace?
An open damper allows smoke and other harmful gases produced by a fire to escape from the fireplace, and to also provide further air from the outside to help keep the fire going. If the damper is closed when a fireplace is in use, smoke and gases will enter into the room, which can be a potentially serious health hazard if not dealt with quickly.
How are fire rated dampers tested for fire alarms?
· For Fire-rated dampers, Verify that all connections needed for the interface with Fire Alarm and Smoke Control systems are available. · All connections made between the MSFD and FAS will be tested during FAS System Pre-Commissioning. · All connections between the MSFD and Smoke Control system will be tested during System Pre-commissioning.
How is MSFD tested on a motorized damper?
· During Testing of each Motorized Damper, issue an open/close command from DDC HMI and make sure the damper modulates to 100% open/close position. · Based on Sequence of Operation, the damper should react in compliance with programmed output. · MSFD Controlled by FAS, the Test of MSFD will be done during FAS Pre-commissioning.
What does a backdraft fire damper do for You?
Dampers are built with blades designed to allow air to flow through in one direction out of the house, keeping cold air outside during the winter months. Backdraft dampers are easy to install. How much does a fire damper cost? The average cost of fire damper testing and inspections is between $40-$150 per fire damper.
