NFPA 13 Occupancies for Sprinkler Design
An assortment of building occupancy examples are classified in Sec. A.5.2 of the NFPA 13 Appendix. The following are noted as light hazard occupancies: offices, churches, schools, museums, auditoriums, library seating areas, restaurant seating areas, and unused attics. The maximum sprinkler spacing (protection area) for these is noted in Table 8.6.2.2.1(a) if standard sprinklers are used. Usually, the maximum limit is 225 square feet for light hazard on a hydraulically calculated system. However, when exposed construction is combustible, with structural members spaced less than 3 ft. apart, the maximum coverage limit shrinks to 130 square feet.
NFPA 13 Occupancies for Sprinkler Design
Ordinary hazard Group 1 occupancies include laundries, restaurant service areas, and automobile parking garages. Ordinary hazard Group 2 occupancies include the aforementioned dry cleaners, automobile repair and services areas, auditorium stages, woodworking plants, post offices, and stack room areas of libraries. Standard sprinklers protecting all ordinary hazard occupancies shall not cover an excess of 130 square feet per head (Table 8.6.2.2.1(b).

NFPA 13 Occupancies for Sprinkler Design
Extra hazard occupancy examples include printing plants, paint and varnish dipping operations, plywood manufacturing, solvent cleaning, and plastics processing. Maximum sprinkler spacing for these occupancies is limited to 100 square feet. However, where the required design density is less than 0.25 gpm/sf (and this goes for high-piled storage as well), a protection area of up to 130 square feet per sprinkler is allowable (Table 8.6.2.2.1-c). It should be noted that commercial insurance carriers and consultants develop their own literature containing more extensive listings of occupancy examples and classifications than does the NFPA 13 standard, data which often comes in handy when making an occupancy classification determination.

Design Density Criteria
The NFPA 13 Density / Area Curves are found in Fig. 11.2.3.1.1. When hydraulically calculating a light hazard sprinkler system, the design density utilized is typically 0.10 gpm/sf over a 1500 square foot (the most hydraulically demanding) area of operation. To begin a calculation, the designer starts with the end-sprinkler and works "backwards" to the water supply source. Suppose that the sprinklers are spaced 14 ft. apart on branch-lines that are 12 ft. apart. Our square foot coverage then, is (12 x 14) 168 square feet.
Q (in gpm) is determined by multiplying the density by the square foot coverage (.10 x 168), so we know that we'll need 16.8 gallons per minute (Q) discharging out of the end sprinkler.
The square root of the required end-head pressure is determined by "Q" divided by "K". If the design density is 0.10 and the K-factor of the sprinkler head is 5.5, we can ascertain our end-head pressure by dividing 16.8 by 5.5, and squaring the sum to obtain a 9.33 psi figure. 9.33 psi is the required end-head pressure. To double-check, we can simply plug in the numbers while performing the following equations to ensure that they match: Q= K times the square root of the pressure, K= Q divided by the square root of the pressure, and the design density equals Q divided by the square foot coverage. If our area of operation remains 1500 square feet, our design density will change to 0.15 for Ordinary hazard Group 1 occupancies and 0.20 for Ordinary hazard Group 2 occupancies.
Everything changes when extended-coverage sprinklers are employed. Let's suppose that we decide to extend our coverage to 324 square feet in a light hazard office, spacing sprinklers 18' x 18' apart. Now we must refer to the sprinkler manufacturer's data sheets for direction. If we choose to install Tyco EC-11 pendent sprinklers, the data sheets dictate that our end-sprinkler must discharge a minimum of 33 gpm at 8.7 psi. This means that our design density (Q divided by the square foot coverage) is still 0.10 gpm/sf. The K-factor of this particular sprinkler is 11.2, which we can validate by the equation K= Q divided by the square root of the pressure.
Extended-coverage sprinklers for ordinary hazard occupancies work the same way. For example, we could use the Tyco EC-14 extended-coverage pendent sprinkler (K=14.0) in a (Ordinary hazard group 1) restaurant service area to protect an 18' x 18' area, but here the data sheet parameters require a 49 gpm minimum discharge at 12.3 psi for the end-sprinkler. In other words, Q= 49, K= 14.0, the square root of the pressure is 3.51, and the coverage is 324 square feet. All the equations match, including the required design density (0.15) which is obtained by dividing Q by the 324 sq. feet. Of course, the local water supply must still be able to satisfy the resulting overall sprinkler system demand. In order for that to be accomplished, larger system piping is installed to deliver the additional gpm necessitated by the extended-coverage heads.
Sprinkler discharge characteristics are outlined in cogent form in Table 6.2.3.1- these outline the differing K-factors for sprinkler identification. One other handy table to reference for sprinklers in NFPA 13 is Table 6.2.5.1, which deals with classifications and temperature ratings.
To be absolutely certain of code compliance with respect to sprinkler elevations, we refer to Sec. 8.6.4.1 in NFPA 13. The allowable distances noted beneath roofs, beams, or ceilings are always measured to the sprinkler deflector. It is acceptable for designers to consult data sheets for appropriate distances below ceilings for specific sprinkler types, although the safe bet is to call for a distance between 1" and 12" beneath the underside of the roof deck. The closer sprinklers are to the ceiling, the faster they will operate. But caution must be exercised because often serious interferences to lateral water distribution can result from very close sprinkler placement to the ceiling. For all instances, the minimum of 1 inch (in the code) is to allow for the installation and removal of upright sprinklers. When sprinklers are installed beneath pitched roofs, the highest sprinkler deflector (Sec. 8.6.4.1.3.1) may extend 3 ft. down from the highest peak.

Stealing Cinderella - Chuck Wicks with lyrics
stealing cinderella by chuck wicks with lyrics LYRICS: I came to see her daddy for sit down man to man It wasn't any secret i'd be asking for her hand I guess that's why he left me waiting in the living room by myself with at least a dozen pictures of her sitting on a shelf [Chorus;] She was playing Cinderella She was riding her first bike Bouncing on the bed and looking for a pillow fight Running through the sprinkler with a big popsicle grin Dancing with her dad, looking up at him In her eyes i'm Prince Charming But to him i'm just some fella riding in and stealing Cinderella I leaned in towards those pictures to get a better look at one When I heard a voice behind me say "Now, ain't she something, son?" I said "Yes, she quite a woman" and he just stared at me Then I realized that in his eyes she would always be Playing Cinderella Riding her first bike Bouncing on the bed and looking for a pillow fight Running through the sprinkler with a big popsicle grin Dancing with her dad, looking up at him In her eyes i'm Prince Charming But to him i'm just some fella riding in and stealing Cinderella He slapped me on the shoulder Then he called her in the room When she threw her arms around him That's when I could see it too She was Playing Cinderella Riding her first bike Bouncing on the bed and looking for a pillow fight Running through the sprinkler with a big popsicle grin Dancing with her dad, looking up at him If he gives me a hard time I can't blame the fella I'm the one ...

How to Wire Sprinkler Valves to the Timer
How to Wire Sprinkler Valves to the Timer
It can seem like a difficult task, but it is actually pretty easy if someone tells you how to do it. You will need a pair of wire strippers and a small screwdriver.

Where to Buy the Right Wire
The first step is to buy the right wire. Sprinkler wire is sold at hardware stores and sprinkler supply stores. If you need a lot of wire, it is better to shop at the sprinkler supply store. Sprinkler wire is an 18 gauge wire.
Number of Strands
A strand is the same thing as one wire. You should get one more strand than the number of valves being used. For example, a seven valve system would use an eight stranded wire (eight wires).
Solenoids
There is one solenoid per valve. Each solenoid has two wires already connected to it. Pick one wire from each solenoid and twist them tightly together. It doesn't matter which solenoid wire you pick.
White Wire or Common Wire
It's an unwritten rule that the white wire will be the common wire. Stick by this rule to prevent confusion by others working on your system. It's called common because it is used on all valves. The white wire will be hooked up to the large bundle of solenoid wires. For example, if you have four valves there will be four solenoid wires and one white common wire all hooked together with a wire connector.
Pick your Colors
Once the white wire is connected to one wire from each solenoid, pick any color you wish and connect it with a wire nut to the other solenoid wire. On a four valve system you might pick blue, black, green, and red for each valve and run the white wire to each valve as well. In total, for four valves, you will need five strands of 18 gauge sprinkler wire. Keeping track of colors will help you know which timer station will turn on which valve.
Run the Wire Back to the Clock
Take the wire to the timer. To get wire into the garage, it is helpful to use a hammer drill and some foam sealant around the wire hole.
Hooking Up the Timer
You will need a small screwdriver for most timers. Connect the white wire to the terminal that says C. Connect the colored wires to the additional terminals. It doesn't matter what order the colored wires are installed. You may want to have the wires in a certain order for your convenience, but it's not required. For example you may want station 1-3 to be the front yard only.
You will also need to hook up the power. Connect the power pack to the ac terminals. If you are using an outdoor timer, make sure you have a pigtail instead of an ac adapter.
Final Tip
Most contractors use silicone filled wire nuts. The theory is that they keep out water and make the connection last longer. However, many landscapers disagree. The silicone keeps out water but interferes with making a good tight connection. For this reason, we recommend using regular wire nuts. The ultimate wire connection is a regular orange wire nut in a grease filled cap. They are made for direct bury and somewhat over kill for sprinkler boxes, but if you want quality they will do an awesome job.

Original Motion-Activated Sprinkler vs. Pigeons
The sprinkler is the ScareCrow from Contech. You can find more info at contech-inc.com and I hear they're now available at WalMart and garden stores in addition to the usual online sources. I originally uploaded this video in 2007 and it sat there for several months with a few dozen views from me and my friends. Suddenly it took off, getting hundreds of views. Turns out someone had stolen it from YouTube and posted it on another site that awards money for selected videos. My video had been selected and the thief would have presumably claimed the prize, but I contacted the site and provided proof that this pool is in my back yard and the video belongs to me. (It helps that I put my podcast's URL on the video.)
