32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Light hazard density
- NFPA 13 design density of 0.10 gpm/ft² applied over a 1,500 ft² remote area for occupancies such as offices, churches, and schools with low combustible loading.
- Ordinary Hazard Group 1
- Design density of 0.15 gpm/ft² over 1,500 ft² for occupancies like parking garages and mechanical rooms with moderate combustibility and low fuel quantities.
- Extra hazard density
- Design density of 0.30–0.40 gpm/ft² over 2,500 ft² for occupancies with high fuel loads or flammable liquids, where sprinkler discharge must control rapid fire growth.
- Hazen-Williams coefficient
- Friction loss factor C used in the formula p = 4.52 Q²/C²d⁴; typical values are 120 for steel pipe, 140 for copper, and 150 for cement-lined cast iron.
- End sprinkler pressure
- The minimum 7 psi operating pressure required at the hydraulically most remote sprinkler; it anchors the remote-area calculation and drives branch line sizing.
- Deflector distance
- Vertical distance from the ceiling to the sprinkler deflector: 1 to 12 inches for pendants, 4 to 12 inches for sidewall sprinklers under NFPA 13.
- Sprinkler temperature rating
- The activation temperature class of a sprinkler: ordinary 135–170°F, intermediate 175–250°F, high 255–300°F; selected at least 30°F above maximum ceiling temperature.
- NFPA 13 scope
- The standard for design and installation of automatic sprinkler systems in commercial, industrial, and storage occupancies; the base document for hydraulic and pipe schedule design.
- NFPA 13R scope
- The reduced standard for automatic sprinkler systems in residential occupancies up to and including four stories, with simplified design and omission allowances.
- NFPA 13D scope
- The standard for automatic sprinkler systems in one- and two-family dwellings and manufactured homes, emphasizing life safety with limited water supply duration.
- NFPA 14 standpipe classes
- Class I provides 2½-inch outlets for fire department use; Class II provides 1½-inch outlets for occupant use; Class III provides both types in the same system.
- NFPA 20 fire pump
- The standard for stationary fire pumps; requires a pump to deliver at least 95% of rated pressure at 150% of rated flow and churn pressure not over 140%.
- NFPA 25 inspection
- The standard for inspection, testing, and maintenance of water-based systems; includes quarterly alarm tests, annual main drain flow tests, and five-year internal pipe inspections.
- NFPA 24 private mains
- The standard for private fire service mains; requires minimum 6-inch diameter for fire protection, thrust blocks at bends, and minimum cover per local frost depth.
- FBC Chapter 9
- The Florida Building Code chapter governing fire protection systems; sets when sprinkler systems are required by occupancy group and area thresholds.
- Florida Fire Prevention Code
- The state code adopting NFPA 1 and NFPA 101; enforced by the local fire marshal alongside the Florida Building Code, with both approvals often needed for permits.
- High-rise sprinkler threshold
- Florida requires automatic sprinkler systems and standpipes in buildings where the occupied floor exceeds 75 feet above the lowest fire department access level.
- Supervised control valve
- A sprinkler control valve monitored open by a tamper switch connected to the fire alarm system, as required by FBC-B Section 903.4 and NFPA 13.
- Florida Product Approval
- A state review process for certain building products; system components must also be listed by a nationally recognized testing laboratory such as UL or FM.
- Qualifying agent
- The licensed individual who passes the state exam and is responsible for the contractor's fire protection work; must be actively involved and listed with DBPR.
- Certified vs registered
- A certified Florida contractor may work statewide; a registered contractor is limited to the jurisdictions where the license is registered and locally approved.
- Notice to Owner
- A Florida statutory notice that a subcontractor or supplier must serve within 45 days of first furnishing labor or materials to preserve private-project lien rights.
- Claim of Lien
- A recorded claim filed within 90 days of last furnishing labor or materials on a private Florida project; foreclosure must follow within one year.
- Statute of repose
- Florida's seven-year period from certificate of occupancy after which latent-defect claims against a contractor are barred, regardless of discovery date.
- Plan scale 1/8 inch
- A common architectural scale where one-eighth inch on the drawing equals one foot; used to measure pipe runs and protected areas during takeoff.
- Head count estimate
- Divide the protected floor area by the maximum coverage per sprinkler (225, 130, or 100 ft² by hazard), then add about five percent for obstructions.
- Labor hours per head
- A typical estimating unit of 1.5 to 3.0 hours per sprinkler head, reflecting installation complexity and including branch line and main rough-in time.
- Pendant symbol
- A solid circle on sprinkler plans indicating a pendant sprinkler; a half-circle indicates sidewall and a triangle indicates upright configuration.
- Bid scope inclusions
- Items a sprinkler bid should cover: materials, labor, permits, plan review, hydraulic calculations, shop drawings, testing, and as-built documentation.
- Fall protection threshold
- OSHA requires guardrails, nets, or personal fall arrest for construction work at six feet or more above a lower level under 29 CFR 1926 Subpart M.
- Continuing education
- Florida fire protection contractors must complete 14 hours of continuing education every two years, including one hour each of workers' compensation and business practices.
- Sunshine 811
- Florida's one-call system; excavators must notify at least two full business days before digging so underground utilities can be located and marked.
