What is a Category 1 sprinkler system?
Sprinkler system CATEGORY 1. Individual dwellings (houses), HMO’s, B&B’s, Boarding Houses. Calculate for 1 or 2 sprinkler heads operating. Average 84-100 litres/minute. Storage for 10 minutes supply.
What is a residential fire sprinkler system?
A fire sprinkler system is a simple, but key, active component of a domestic or commercial building’s fire protection system. Installed in ceilings or side walls, the system consists of a water supply, a water distribution piping system and sprinkler heads.
What is the difference between wet and dry sprinkler systems?
Wet vs. Dry Pipe Sprinkler Systems In a wet system, the pipes are filled with pressurized water. When a fire occurs, the system immediately discharges water to extinguish the fire. Conversely, dry systems are filled with pressurized nitrogen or air that keeps water at a riser.
Can you use PEX for fire sprinkler system?
NFPA 13D-approved for use in multipurpose and standalone fire sprinkler systems, PEX has been shown to be an effective alternative to CPVC and copper pipe due to its easy installation and durability. Both characteristics allow contractors and builders to meet tight production schedules.
How often do you need to replace fire sprinkler heads?
Annual inspections help ensure the system is working correctly, and no rust or water back-up has occurred. Even with regular maintenance, sprinkler heads do not last forever. Fire safety protocol recommends you get sprinkler heads replaced once every five years to prevent fire sprinkler leaks.
How often should sprinkler heads be inspected?
Every 10 years
How often should you have your fire sprinkler system tested?
| Fire Sprinkler Component | Testing Schedule |
|---|---|
| Dry sprinklers (Test or Replace) | Every 10 years |
| Fast-response sprinklers (Test or Replace) | 20 years initially, then every 10 years |
| Standard response sprinklers (Test or Replace) | 50 years initially, then every 10 years |
What is a Category 2 sprinkler system?
Category 2 covers large blocks of flats (over 18M high) and small residential care homes (10 residents or less).
What are the three fundamental types of sprinkler systems?
3 Types of Fire Sprinkler Systems
- Wet Fire Sprinkler System. A wet fire sprinkler system is one of the most common options on the market.
- Dry Fire Sprinkler System. A dry fire sprinkler system is filled with pressurized air, rather than water.
- Preaction Fire Sprinkler System.
Does sprinkler system add value to home?
A sprinkler system indirectly increases a home’s market value by enhancing the home’s overall curb appeal. Since attractive landscaping requires sufficient watering, an automatic sprinkler system ensures the protection of your investment.
What kind of pipe is used for fire sprinkler systems?
steel pipe

What is a major disadvantage of a wet pipe system?
The main disadvantages of wet pipe systems are: They are not suited for sub-freezing environments. Damage to piping or sprinklers will likely result in water leaks and subsequent water damage.
How many fire sprinkler heads do I need?
New fire codes allow a single sprinkler head to protect up to 200 square feet, depending on the design of the fire sprinkler, flammability of the building and the materials within it. The NFPA delineates spacing requirements based on the material hazards, plumbing, and piping systems of the specific construction.

|---|---|
| Sprinklers | At 75 years and every 5 years thereafter |
| Dry Sprinklers | 10 years and every 10 years thereafter |
| Sprinklers (extra high or greater temperature solder type) | 5 years |
| Fast Response Sprinklers | At 20 years and every 10 years thereafter |
How many spare sprinkler heads are required?
six spare heads
According to the NFPA 13, if you have 300 sprinklers or less, you should have no fewer than six spare heads; if you have 300 to 1,000 sprinkler heads, you should have no fewer than 12; and if you have more than 1,000 sprinklers, you should have no fewer than 24 spares.

Current fire safety codes require sprinkler heads always to be a minimum of 6 feet apart from one another to avoid cold soldering.
Does Scottsdale have fire sprinkler systems?
Fire Sprinkler Systems. The City of Scottsdale is widely recognized as a leader in built-in automatic sprinkler systems. In 1985, the City passed an ordinance requiring every commercial and multi-family building to be outfitted with a complete fire sprinkler system.
Do fire sprinkler systems cause water damage?
Fact: Water damage from a home fire sprinkler system will be much less than the damage caused by water from firefighting hoses or the smoke and fire damage if the fire continues unabated. “A smoke alarm is enough protection from fire.”
Are automatic fire sprinkler systems any good?
Automatic Fire Sprinkler systems have enjoyed an enviable record of protecting life and property for more than 100 years. However, there are still common misunderstandings about the operation and effectiveness of automatic fire sprinkler systems.
How many sprinkler heads does it take to control a fire?
Residential fires are usually controlled with one sprinkler head. A 15-year study conducted in Scottsdale found that 2 or less sprinkler heads controlled more than 92 percent of the fires that occurred in protected properties. “Water damage from Fire Sprinklers will be more extensive than the fire damage itself.”
