This chapter covers the design and installation of automatic sprinkler systems for the protection against fire hazards in one- or two-family dwellings and manufactured homes. Where new dwellings are built with more than two units, the NFPA 13R standard shall apply.
A. 
The purpose of this chapter is to provide a sprinkler system that aids in the detection and control of residential fires and thus provides improved protection against injury, loss of life, and property damage. A sprinkler system designed and installed in accordance with this chapter is expected to prevent flashover (total involvement) in the room of fire origin, where sprinklered, and to improve the chances for occupants to escape or be evacuated.
B. 
Guidelines have been established for the design and installation of sprinkler systems in one- and two-family dwellings and manufactured homes. Nothing in this chapter is intended to restrict new technologies or alternative arrangements, provided that the level of safety prescribed by the chapter is not reduced.
A. 
All sprinkler systems designs shall be in accordance with the requirements of NFPA 13D, as modified by this chapter. A set of plans must be submitted to the Building Inspector with an application for a building permit. All required approvals shall be obtained prior to the installation of any sprinkler piping or components. Approval shall be by the Española Fire Department or its designee.
B. 
Any components of the sprinkler system, other than those required for domestic water supply, shall be installed by personnel licensed for such work. Inspections during construction will be done by the Building Inspector, or his designee. Acceptance testing/final test shall be performed in accordance with NFPA 25, sprinkler system acceptance test. This test will require a flow test, observed by the Española Fire Chief or his designee, at the most hydraulically demanding head location.
All definitions shall conform to NFPA 13D unless otherwise approved. As used in this chapter, the following terms shall have the meanings indicated:
APPROVED
Acceptance to the Española Fire Department.
SLOPED CEILINGS
Those ceilings having a greater-than-ten-degree angle (176%) with a ceiling height greater than nine feet.
SYSTEM STORAGE
A reserve of water on site, specific for the sprinkler system, calculated for the two most hydraulically demanding sprinkler heads to flow water for 10 minutes.
A. 
In those areas of Española that are not served by an approved, pressurized water system, the delivery and reserve capacity aspects of the sprinkler system are a critical aspects of the design. Based on NFPA standards, the design specifications of sprinkler systems are based on either a two- or three-sprinkler-head coverage area design.
B. 
The sprinkler system for a dwelling containing sloped ceilings shall be based on a three-head system design, and shall provide a minimum flow of 25 gallons per minute to the most hydraulically demanding head, with a system minimum storage capacity of 250 gallons.
C. 
All other dwellings shall be of a two-head system design, and shall provide a minimum flow of 16 gallons per minute to the most hydraulically demanding head, with a system minimum storage capacity of 160 gallons. Bathrooms, of any size, are required to be sprinklered.
D. 
A Fire Department connection shall be installed and shall be maintained at all times and without obstruction by fences, bushes, trees, walls or any other object. An exterior audible alarm and visible light signal shall be installed. The sprinkler shall activate the fire alarm system or the dwelling's smoke detectors. All attached garages or those that are located under living spaces shall be protected by the sprinkler system.
(Page 6, Section 1-4, of NFPA 13D) The owner is responsible for the condition of a sprinkler system and shall keep the system in normal operating condition.
A. 
This chapter allows for the installation of an approved residential sprinkler system to be installed in all dwellings in lieu of proper access or fire protection. However, when the Española Fire Department deems that, due to specific conditions, there is sufficient threat to life or property, it may recommend additional fire protection measures to be provided.
B. 
It is important to understand that during an electrical power outage the sprinkler system as required by NFPA 13D will not operate. This may be remedied by the installation of a self-contained system or a backup power supply.
