Why is it Imperative to Install Fire Smoke Dampers in Duct System?

Different types of dampers are usefully installed in the HVAC ventilating systems. These dampers do have varying responsibilities and are helpful in maintenance of the HVAC system as well as for safety. Fire damper, sound damper, and smoke damper are few of the commonly used dampers in HVAC system.

Alike the fires dampers are used for obstructing the fire from spreading in the entire duct system; the smoke damper is responsible for obstructing the smoke from the space of origin to the other spaces. These smoke damper act as a barrier for obstruction of the smoke in the duct system; these can even be installed in the walls as the physical smoke barriers.

Fire smoke dampers responsibly exhausts and blocks smoke from spreading

The combination of fire smoke dampers with fans and dampers exhaust the smoke from the area, by pressurizing the smoke areas in the affected space. The smoke damper can also be activated with the help of a fire alarm system which is instigated by the smoke detectors.

These are also interlocked in the fire suspension system. The smoke damper is closed by an electric actuator or a spring actuator. The smoke damper can also be set manually for opening, to reset the signal to the electric actuator.

Install the fire smoke dampers in the exact location

You can get the combination of fire smoke dampers if you desire to install the smoke barrier at the exact location of the fire barrier. The smoke, as well as fire dampers, is certified by UL, which is regulatory for certifying the dampers to be leakage free and of high quality with high resistant power.

As being among the integral parts of the ducting system for these passive fire protection feature, the fire and smoke damper are inspected with the best tests by the professional and highly talented inspection team. They certify the smoke and fire dampers to be safe and reliable to be used in the ducting system.

UL 555 and UL 555S Graded Fire Smoke Dampers Are Advised To Be Installed

The smoke dampers are labeled to be UL 555 tested which is the best grade of safety and reliability. One must ensure to pick the UL 555 graded fire as well as a smoke damper. The smoke damper is designed and constructed with the technology that would restrict the smoke from spreading in the HVAC system.

It shuts down automatically when the temperature rises, and it senses the threat of fire. At a reputed and reliable damper supplier, you can find several models that are inspected and tested well to ensure the best grades.

UL certifies the dampers to be safe, reliable, durable and excellent Performing

Inspection of smoke, as well as the fire dampers, is imperative. This certification helps in maintenance of the specialized and effective dampers and ensures those to be in working order.

As per the National Fire Protection Association, the smoke and fire dampers need to be inspected after a period of one year after they are installed in the ducting system. It is your responsibility to get the dampers inspected as per the regulations and standards to ensure durability, efficiency, and performance with safety.

Pick the fire and smoke dampers from reliable and trustworthy manufacturer

The smoke damper is installed in or near to the smoke barriers in the ducts. The combination of the fire and smoke damper must meet the standard requirements of UL for ensuring safety. UL 555 grade for fire damper and UL 555S for the smoke damper.

It is imperative to have both of the dampers, i.e. fire and smoke for ensuring safety. Both of the dampers combining together close automatically with detection of heat or smoke and block the opening preventing from spreading in the duct system.
