Fire protection systems can help manage or extinguish fire, aid in occupant evacuation, and help protect property from damage. PFP systems, on the other hand, include building elements such as fire and smoke rated walls and floors that are used to separate parts of the building.

While penetrating these barriers with ductwork should be avoided if possible, sometimes it is necessary. Fire dampers are designed for the purpose of preventing the spread of flames across a rated barrier.

A fire damper is installed within the duct where the duct intersects the barrier. They operate using a heat sensitive device that, when activated, melts and causes the damper components to close. A smoke damper can also be installed within flux pavilion what you gonna do about it duct, and is activated by a signal from a smoke detector within the damper.

Upon detection of smoke, the actuator will automatically close the damper components. An FSD can also contain an electric heat release device, which can be reset, and allows the damper to close in a more controlled way, rather than slamming shut when the heat sensitive device melts. FSDs will also close upon electrical power failure, as they are held open by a powered actuator.

This means that they can be interlocked with the building fire alarm system such that they close after receiving a signal from the fire alarm system. So, we know the difference. But how do we know which one to use? The simple answer is that the rating of the damper should match the rating of the barrier that it is protecting. For example, if the barrier is only rated to prevent the spread of fire, only a fire damper is required.

If the barrier how to install fire dampers rated to prevent the spread of smoke and fire, an FSD is required. FSDs are larger and more expensive than fire dampers, so they are generally only used in barriers that are fire and smoke rated. FSDs are listed with both a fire rating and a leakage class. The mechanical code governing the area in which your building is located will determine how the FSD is selected.

Below is a reference from the International Mechanical Code showing the requirements for fire and smoke dampers. Also shown below is an example of an FSD that would meet these requirements when installed in an assembly with less than how to install fire dampers 3-hour fire resistance rating.

In order to properly protect a building and its occupants, the active and passive fire protection systems must work together effectively. These elements protect buildings from property damage, and allow for proper occupant evacuation in the event of a fire emergency.

A fireplace damper, usually located at the very bottom of the chimney, will keep the warm air in the room from escaping from the home.

When the fireplace is not in use, the damper should be turned in the shut or closed position to prevent the cold air from entering into the room or the home. Fireplace dampers are used in both gas fireplaces and wood burning stove fireplaces. Below is a quick guide on how to install a damper in your fireplace. Open the doors completely to your fireplace. Pull back the screen. Since you will be down at the bottom of your fireplace, this is a good time to pull out the logs and give the space a little clean.

Before you proceed, spread out several old sheets or drop cloths over the floor and furniture. This will help to protect your open surfaces from getting soot and other dirt or grime on them while you clean the fireplace. Remove the logs and place them nearby. Use a broom to sweep up the excess soot and dirt that has accumulated at the base of your fireplace. If you have excess build up in your chimney, it's a good time to clean it out as well.

Be sure to wear the proper safety equipment. Locate the damper and remove it from the chimney. Most dampers are designed to simply pop out, but some models require that you use a Phillips head screwdriver to remove them.

Take your old damper with you to a chimney supply store. You can sometimes find these parts at large big box home improvement centers as well. Make sure you purchase a damper that is similar in style and function as the one you have removed. Follow the manufacturer's instructions to install it into your fireplace.

Tighten as required. Open the damper so that you can test it. A damper should always be in the open position when you are burning a fire. This will prevent unnecessary smoke and odors from penetrating into the room during the time when the fire is burning. Put the logs and the log cradle back into the base of the fireplace. Clean up in and around the fireplace. Put the screen back in the closed position and close the doors if there are glass doors present. In addition, pull up the tarps or sheets carefully in order to capture any remaining dust or grime.
