Residential Sprinklers
Residential Sprinklers: Installed to provide an increased
level of life safety for the occupant. Residential sprinklers
are designed to prevent flashover, keeping the living space
survivable for a minimum amount of time.

Residential Sprinklers
Residential sprinklers are tested to a separate UL standard.
The testing procedure verifies the thermal sensitivity and
water distribution characteristics.
UL 1626, Residential Sprinklers for Fire Protection Service
It is not a design document, It is a standard published andused by UL to evaluate the performance of a residential
sprinkler.

Residential Sprinklers
The scope of UL 1626 is defined within the document as:
These requirements cover residential sprinklers intended for
installation on sprinkler systems for fire protection service.
Requirements for the installation and use of residential
sprinklers for the Installation of Sprinkler Systems, NFPA 13,
and Installation of Sprinkler Systems in One- and Two-FamilyDwellings and Mobil Homes, NFPA 13D and Residential
Occupancies up to and Including Four Stories in Height

Residential Sprinklers
Residential Sprinklers are required to pass special fire tests.
The objective of residential sprinklers is to provide safety to
the occupant and allow safe egress in a fire.
In a residential fire test, the temperature cannot exceed 600 F
3 below the ceiling where the thermocouples are installed.
The maximum temperature at 5-3 above the floor is 200 F.The temperature 5-3 above the floor shall not exceed 130 F
for any continuous 2 minute period.
The maximum ceiling material temperature behind the
finished ceiling surface shall not exceed 500F.

Residential Sprinklers
A special room is used to test residential sprinklers that simulates
a residential occupancy. (2) residential sprinklers are located in
the room for their coverage area. For a pendent sprinkler, theseareas of coverage are 12x12, 14x14, 16x16, 18x18, and 20x
20. For sidewall sprinklers, these areas of coverage are typically
14x14, 16x16, 16x18, 16x20, 16x22, 18x18 and 20x20.
The (2) sprinklers are installed at the coverage area that a listing
is desired at. A third sprinkler is located near an open door. The
sprinkler at the door is not connected to water filled piping. If the
sprinkler at the door activates at any time during the test, the testis considered a failure.

Residential Sprinklers
Residential sprinklers are required to meet minimum
wall wetting characteristics. 28 is the maximum distance down
from the ceiling on the wall that a residential pendent andsidewall sprinkler must wet the wall.
Sidewall sprinklers must direct 5% of their discharge upon
the wall on which they are installed.
These wall wetting characteristics mean that a residential sprinkler
must discharge or spray in a very flat pattern. Obstructions such
as sloped ceilings, beams, ceiling fans, and lights can inhibit theperformance of residential sprinklers and must be avoided.

Residential Sprinklers
The minimum design criteria for residential sprinklers per UL
And NFPA 13D and NFPA 13R is to provide a minimum
.05 gpm per sq. ft. over the area of protection.
NFPA 13 requires that the minimum design criteria for
residential sprinklers or residential occupancies be a .10
gpm per sq. ft.
Each residential sprinkler must pass the special fire tests and
wall wetting requirements before they are listed as residential
sprinklers.

NFPA 13D Occupancies
-
7/30/2019 Noh Aspe Asse Ppt
18/96
NFPA 13D One and Two Family Dwellings and
Manufactured Homes
NFPA 13D is the design and installation standard for
single and two family dwellings, or in other words a home
that is a single structure.
The sprinkler design for this type of occupancy is for (2)
residential sprinklers to discharge at the minimum flow rate
and pressure of its UL listing.
Water supply capacity is generally an issue for these system
designs, so it may be prudent to utilize more residential
sprinklers in a system at smaller spacings to lower the watersupply requirement.

NFPA 13 R Occupancies
-
7/30/2019 Noh Aspe Asse Ppt
20/96
NFPA 13R Residential Occupancies up to and Including
Four Stories in Height
Generally these NFPA 13R occupancies
are apartments, dormitories, hotels, motels
The residential sprinkler design criteria for the residentialdwelling requires that (4) residential sprinklers are designed
to operate at their listed flow rate and pressure for the area
of coverage to be protected.
Public areas such as corridors, require a design per NFPA
13, meaning the water supply needs to adequate for a NFPA
13 installation.

NFPA 13 Residential Occupancies
-
7/30/2019 Noh Aspe Asse Ppt
22/96
NFPA 13 Residential Occupancies that are not NFPA 13D
Or NFPA 13R
These occupancies are buildings that are greater than (5)
stories, typical of high rise apartment buildings, large hotel
resorts, etc.
The design requirement per NFPA 13 is for a minimum .10
gpm per sq ft or the residential sprinklers listing for the
area, which ever is greater.
Water supply requirements are higher for NFPA 13 residential
occupancies because the water flow is providing protection
to the structure as well as life safety.

Residential Sprinklers
Due to the minimum flow rate requirements for residential
sprinklers there are many different K factors for residential
sprinklers to address different coverage areas and differentcode requirements, (NFPA 13D and NFPA 13R versus NFPA
13 residential occupancies)
The K factors step up from smaller areas of coverage of NFPA13D, to moderate and large areas of coverage of NFPA 13R,
to very large water demands of NFPA 13. These specific K
Factors allow for the most efficient use of water and pressure.

Additions to the deluge valve and trim
will be a riser check valve, an airsupply, and closed head sprinkler
piping.

The Release System must activate ..-(an alarm will sound)
-AND,
-Pressure in the sprinkler piping must be reduced-(due to a sprinkler opening in fire conditions)
To trip open the Deluge Valve.
In fire conditions,
- After the release system operates and the sprinkler
opens, water needs to travel from the Deluge Valve
to the open sprinkler.There may be a time delay similar to a Dry System.

Fail Safe Preaction SystemsFail safe pre-action systems are pre-action systems that
will operate when there is a loss of AC and DC power.
Some municipalities have fail-safe pre-action
requirements. In general, pneumatic release pre-action
systems are listed and approved fail-safe pre-action
systems.
You should check with the manufacturer if they have a
listed or approved fail-safe electric release pre-action
system option.
