that depends upon what type of sprinkler it is, what type of occupancy it is installed in, what standards apply for inspection, and any special circumstances that may require more frequent inspection (e.g., level of hazard, partial sprinkler coverage, freezing season, etc).
NFPA 25, for example, contains charts for the required inspection frequency for various components of water-based fire protection systems. Certain sections of NFPA 101 may grant some leeway on some elements or on the required frequency, depending upon the type of occupancy and the level of hazard being protected.

According to National Fire Code and most state codes, you need to inspect any fire extinguisher in a commercial occupancy no less than monthly. Some types may also require annual testing or maintenance.

How can you tell if a sprinkler system is a dry system?
That is simple. Look for one or more air pumps at the sprinkler system riser. The pump(s) will have a gauge, also, in the line showing what the current air PSI may be at any given time. The gauge may be labeled on its face "Air" but it may not be so marked. A sprinkler contractor's test report to the customer will also show whether the whole system is an air system or if it has both air and "wet" systems present in the building.
Have often should you test fire alarms?
Once a week.
If a building sprinkler system has a sprinkler head of 50 years old is it still good?
It depends. NFPA states that sprinklers over 50 years of age should be replaced or should have a representative sample tested. This means that sprinkler samples need to be pulled from the system and sent to a testing laboratory (UL) for testing. If the sprinkers pass this test, a certificate is issued stating that the sprinklers are still operational.
What is the average gallons per hour of water used in a residential sprinkler system?
"The average sprinkler will use in excess of 240 gallons of water per hour" also refer to http://www.libertylake.org/water_conservation.htm for watering guide. As a useful gauge: A garden hose with no nozzle attached, will spew out as much as 350 gallons per hour. So 240 sounds about right for a sprinkler system, keeping in mind that it will vary with your local water pressure and type of sprinkler system that you have. If your system has a damaged sprinkler head, you might as well be running that garden hose full blast. My sprinkler system uses 1,000 gallons in a three hour time cycle. I have six or seven zones. I suspect some of my heads are busted, since that sounds about like "garden hose figures." (333 gallons per hour)
How do you install a sprinkler system?
There are two main methods of sprinkler system installation: open trench and pulled pipe. Open trench typically uses PVC pipe and pulled pipe typically uses poly pipe. Other than the pipe and fittings, the main difference in installation will be that the pulled pipe system requires a hole and saddle tee at the location of each sprinkler head. The steps for installing an automatic sprinkler system using an open trench method are: 1. Start with a good sprinkler system design (try searching "sprinkler system designer" for support options) 2. Make sure that you have all necessary tools, equipment, and permits 3. Have Blue Stakes mark all utilities prior to any digging 4. Install a backflow prevention device according to code 5. Place flags at the location of each sprinkler head 6. Mark and dig all trenches and valve manifold locations 7. Build and install valve manifolds (preassembled valve manifolds can make this easier) 8. Connect mainline pipe from water source connection to valve manifolds 9. Lay lateral line pipe from the valve manifolds to the location of each sprinkler head 10. Install tees and swing assemblies for each sprinkler head and flush lines 11. Connect sprinkler heads to swing assemblies; set head to level with ground 12. Install sprinkler timer/controller and connect sprinkler wire from timer to valve manifolds 13. Install nozzles on sprinkler heads 14. Install valve boxes (as required) and backfill all trenches 15. Run a zone by zone test and adjust nozzle patterns
What is a fire Pump churn test?
The fire pump churn test, is when an operator runs the fire pump without the flow of water
How does a sprinkler flow alarm system work?
There are many types, but primarily a flow alarm works by a pressure switch that indicates a pressure drop when a sprinkler head (or test valve) opens, or an actual in-flow mechanism (a propeller or a movable flap) that moves when water flows. Some early models (still in existence) run water through an impeller that moves a clapper in a gong while water is flowing.
How do you perform a hydrostatic plumbing leak test?
To perform a hydrostatic test on plumbing/pipe you must pressurize the the pipe to the pressure that your local authority having jurisdiction has established. The system will be pressurized with water to various psi's depending on what king of pipe was used. I work in the fire sprinkler industry, and when we hydrostatic test a fire sprinkler system we "charge" it to 180 psi and then it must maintain that pressure for a period of 2 hours losing no less than 3 psi. The pump we use is comprised of an electric motor that is connected to compressor type valve body like the ones you see on a pressure washer. We connect a water hose to the intake side of the valve body and then pump water into the system through an orifice that is downstream from the main check valve. We leave an axillary drain open that is located at the farthest point from the water main that is supplying the system. We allow water run through the system until any and all air has been purged from the lines. Then we close the drain and as I stated earlier we pump it up to 180 psi. Obviously you will not pressurize pvc,cpv, or most other types of pipe that way. If I were you I would see if I could find a code book that was written for the jurisdiction you are in and go from there.
