Leyon Fire Fighting Upright,Concealed,Pendent,Sidewall Series Sprinkler Head

Fire Sprinkler Pendants: the pendant fire sprinkler head is the most common type that you will see. Pendant sprinkler heads descend from the ceiling with a convex, circular, gapped deflector plate on the bottom.

When the sprinkler heads activate, they send a stream of water downward onto their deflectors, which then disperse the water widely, side to side, throughout the room in a conical pattern.

Because the pendants extend from the ceiling, they provide the greatest amount of coverage of the space. There are many variations of the pendant, and it can be very effective in protecting a variety of buildings and spaces, from industrial buildings to daycares.

Concealed Pendant: when a pendant sprinkler head is recessed into the ceiling and concealed by a decorative cap that blends in flush with the ceiling, this is called a concealed pendant head. For those who are concerned about fire sprinkler pendants messing with their aesthetic, concealed pendants are an excellent option.

While it may seem like the decorative caps would hinder the sprinkler heads from operating, they are designed to fall away from the sprinkler head when the temperature reaches 20 degrees below the sprinkler system activation temperature. The plate will no longer be in the way if and when the temperatures are high enough to activate the system.

Upright Sprinkler Heads: upright sprinkler heads are pretty much what they sound like – sprinkler heads that point upward toward the ceiling with a circular, concave deflector plate on top (think umbrella).

Rather than descending through the ceiling, these sprinkler heads are usually mounted on pipes just below the ceiling. When activated, the water shoots up out of the pipe, hits the deflector, and is sent out and down in a dome-shaped pattern.

Upright sprinkler heads are efficient at dispersing water between obstructions. Thus, they are frequently used for rooms that are inaccessible, such as mechanical rooms, and in warehouses and industrial spaces. They are also often applied in structures with open ceilings.

An additional benefit to upright sprinkler heads is that since the deflector covers over the sprinkler head, it also protects it from debris and ice collecting.

Sidewall Sprinkler Heads: sidewall sprinkler heads protrude horizontally out of the wall parallel to the floor, rather than descending from the ceiling or mounted on a pipe pointing upward. Sidewall sprinklers are ideal for small spaces, such as hallways, spaces with obstructions, and/or where ceiling piping is not available.

The sidewall sprinkler head has a solid, rectangular, or semi-circular deflector plate that helps to disperse the water away from the ceilings and down and out in a crescent-shaped spray, directly towards the open space it is protecting.
