Existing Cold Weather Valves - An automatic sprinkler system should not be ---- or ---- to avoid freezing during cold weather turned off/drained However, parts of the sprinkler system may be shut down. Permission must be obtained from the local fire house Permission may be given to shut off a maximum of ----sprinkler heads on a wet pipe system. 10 Permission may be given to shut off a maximum of 10 sprinkler heads on a wet pipe system. These shutoff valves are commonly referred to as ----. These valves are no longer permitted to be installed. cold weather valves A sprinkler system employing automatic sprinklers that are attached to a piping system containing air or nitrogen under pressure, the release of which (as from the opening of a sprinkler) permits the water pressure to open a valve known as a dry pipe valve, and the water then flows into the piping system and out the opened sprinklers. Dry Pipe Sprinkler System Dry Pipe Sprinkler Systems are installed ---- since the protected area cannot be heated to prevent freezing conditions. In where it is impractical to install a wet pipe system (dry piping)In most cases the air pressure in the piping is controlled automatically by an air maintenance device When a sprinkler head is opened by the heat from a fire, the ---- is reduced in the piping. air pressure When a sprinkler head is opened by the heat from a fire, the air pressure is reduced in the piping.

A supervisory device signals when the valve is opened. sprinkler heads open The preaction valve can also be operated manually The preaction system has several advantages over a dry pipe system The preaction valve opens sooner because the fire detectors react to heat changes faster than sprinkler heads. Fire and water damage may be decreased because water is sprayed on the fire more quickly the alarm signal is given as soon as the preaction valve is opened. Heat responsive devices are commonly used to trip pre-action valves. These devices are also used to activate alarm and supervisory systems. There are three main devices used to trip pre-action valves: 1) devices designed to operate at a fixed temperature; 2) devices designed to operate when the temperature in the room increases a set amount in a given time period (rate-of-rise), and 3) devices combining fixed temperature and rate of rise devices. Other ways to activate a preaction valve are smoke detectors, gas detecting systems, hydraulic, electric, manual release, and automatic signals from other safety systems. A supervisory device signals when the valve has opened that will automatically sound an alarm. special kind of preaction system is a recycling system for controlling sprinklers. This system shuts off the water when the fire has been put out or the heat drops. If the fire rekindles or the heat rises sharply, water is discharged again. The system continues cycling on and off as long as the fire persists. Preaction System with a Recycling Feature These systems have the basic features of both types of systems. The piping system contains air under pressure. A heat detecting device opens the water control valve and a quick opening device. The system then fills with water and operates as a wet pipe system. If the heat detecting system fails, the system will operate as a standard dry pipe system. Combined Dry Pipe and Preaction Systems a ---- sprinkler system is equipped with open sprinkler heads designed to wet down an entire area involved in a fire. Deluge systems are suitable for hazardous occupancies. This includes buildings in which -----s or other ----are handled or stored. flammable liquids/hazardous materials The sprinkler heads in the deluge system are ---- at all times open The sprinkler heads in the deluge system are open at all times.

The pressure tank supplies these devices until the Fire Department begins pumping water into the system. Waterflow alarms and fire alarms give warning of the actual occurrence of a fire. They also signal when water flows through the system due to broken pipes. Alarms alert occupants and summon the fire dept Any signal, whether water-flow or supervisory, may be used to sound an audible local sprinkler alarm. It may also send a signal to the central station company In systems equipped with central monitored connections the central station company shall be notified when any control valves are closed for maintenance and repair. This practice reduces false alarms. Sprinkler systems are required to have an approved water ---- or an -----, -----, or --- - on the outside of the building. water motor gong or an electric bell, horn, or siren on the outside of the building. An electric bell or other audible signal device may also be located inside the building Water operated devices must be located near the alarm valve, dry pipe valve, or other water control valves in order to avoid long runs of connecting pipe. Devices and Equipment Supervised . Sprinkler system supervision is commonly provided for several purposes. They are used to 1) water supply control valves, 2) low water level in water supply tanks, 3) low temperature in water supply tanks or ground level reservoirs, 4) high or low water level in pressure tanks, 5) high or low air pressure in pressure tanks, 6) high or low air pressure in dry pipe or pre-action sprinkler systems, 7) failure of electric power supply or phase reversal to fire pumps and, 8) automatic operation of electric fire pumps. The basic design of most water-flow alarm valves is that of a ---- valve which lifts from its seat when water flows into a sprinkler system. This alarm then starts an audible signal to alert the occupants in the building that the sprinkler system has been activated. check ----Switches have a paddle inserted inside the main supply piping perpendicular to the direction of flow. Upon waterflow, the paddle switch transmits an alarm. Vane type waterflow - Vane type water-flow switches shall not be installed to monitor waterflow in dry pipe or pre-action sprinkler systems. An alarm check valve that is exposed to changing water supply pressure needs an alarm retarding device. Alarm Retarding Devices n alarm check valve that is exposed to changing water supply pressure needs an alarm retarding device. This is required to prevent false alarms when the check valve clapper is lifted from its seat by a temporary pressure surge. Vane type water flow switches sensitivity can also be adjusted to changing water pressures. X. SYSTEM COMPONENTS Sprinkler heads are made of metal.

Shifting of the system may occur during pressure surges, water hammer, alterations, testing, or operation. The visual inspection of hanging and bracing for sprinkler systems is not required for piping concealed by building construction above ceilings and in concealed spaces. No other components shall be supported using the sprinkler system piping or hanger assemblies supporting the system. A BRIEF OVERVIEW OF PIPING AND SUPPORT FUNDAMENTALS Sprinkler system piping is categorized as follows Branch lines are directly connected to sprinkler heads Cross mains or loop mains are directly connected to branch lines Feed mains are directly connected to cross mains or loop mains. Risers are able to supply---directly cross mains directly. The vertical supply pipes in a sprinkler system. The spacing of hangers varies with the material and diameter of the piping the location of piping connections, ability of the structure to support the piping he location of the piping in relation to the building structure and system the attachments. Hangers generally consist of an attachment to the piping, an attachment to the building structure, and a ferrous rod attaching the components together. Hanging components are generally required to be listed devices; however, a ---- may also certify that a hanger or hanging assembly may be used. licensed professional engineer A partial list of specific hanger spacing requirements is noted below: Standard wall steel pipe with diameters 1 inch and 1 ¼ inch are equired to have hangers placed at a maximum of ---- feet apart. For all other pipe diameters the maximum distance between hangers is--- 12/15 The maximum hanger spacing for threaded light wall steel pipe shall not exceed-- - feet apart 12 The maximum hanger spacing for CPVC (plastic) pipe varies from a maximum for ¾ inch piping to a maximum --- feet for 3 inches 5 ft 6 inches/10 ft The distance for the hanger assembly to the centerline of an upright sprinkler head shall not be less than----inches 3 For systems operating at pressures of ----psi or greater, the hanger closest to the last sprinkler on the line shall be of the type that prevents the upward movement of the piping within the hanger assembly. This can be accomplished by the use of a ---- restrainer 100/surge The cumulative length of an unsupported arm over to a sprinkler head, sprinkler drop, or sprinkler sprig-up shall not exceed---inches for steel pipe and ---- inches for copper pipe 24/12 The minimum size hanger rods are required as follows: Up to and including 4 3/8, Five, Six and Eight 1/2 Ten and Twelve 5/8 Seismic Restraints The NYC Building Code adopted earthquake code requirements. This reclassification requires the installation of sway bracing for earthquake protection be installed on sprinkler systems in buildings built after 40 Inspection and Maintenance of the Gravity Tank The gravity tank shall be regularly inspected and maintained in accordance with NFPA # 25 2011 edition Tanks are to be painted regularly to prevent rusting.

Only a few sheets of paper or a paper bag tied over the end of the settling basin stub should be used. The paper shall be removed immediately after the job is finished. discharge It is best if gravity tanks are used only for fire protection and for no other purpose. Tanks used for other purposes need to be refilled more often. The FDNY borough ----shall be notified when a tank cannot be used for any reason. dispatcher Pump Inspection and Maintenance In order to ensure the reliable operation of the pump in the case of an emergency, regular inspections and maintenance shall be conducted by the Certificate of Fitness holder. The pump shall be activated as indicated in the reference guide and run for ---- minutes in accordance with the manufacturer's specifications. 10 If an ----controller operates the fire pump, the pump shall be activated by reducing the water pressure in the system. This can be done by opening the test drain or initiating a large water flow from the system. By starting the fire pump this way the Certificate of Fitness holder can determine if the automatic controller is working properly. automatic The ---- pump relies on the water supply for cooling and lubrication and shall never be operated without the pump being supplied with water centrifugal Fire, booster and special service pumps shall be fully tested (how often) to make sure that the pump, driver, power supply and all other parts are functioning properly. annually The most common sprinkler system deficiencies include painted or loaded sprinkler heads, building contents located less than 18 inches below sprinkler deflectors, changes from the original wall locations, ceiling heights, and positioning of mechanical equipment. For concealed sprinkler systems most common defincies are , cover plates with non-factory coatings and the lack of required gap between cover plate and ceiling and blocking of the spray patterns from light fixtures close to the sprinklers Missing ---- or---- plates not attached properly to sprinklers may indicate hanger deficiencies and may not allow the sprinkler deflectors to drop below the ceiling blocking the spray pattern. trim /cover The C of F holder shall assume that the system being inspected is installed is accordance to the NYC Building Code in effect at the time of installation. The C of F holder is to report those items of change that impact the system components regarding, compliance with any retroactive requirements, the condition of the water supply control valves, water and air levels in tanks and condition of same, unusual changes in water supply or system pressures, condition and accessibility of control valves, fire department connections, clearance around sprinkler heads, accessibility of curb valve box ,system control valves , required signage, attachments to piping other than system components, misaligned piping due to impact, missing pipe hangers and supports, excessive operation of pressure relief valves, easily recognized recalled sprinkler heads and visible leakage. Factors that may require further investigation Installations that don't appear to be correct including sprinkler heads located more than 22 inches below the ceiling or structure, sprinklers not installed in accordance with their listing, using sprinklers with different RTI in the same protected area or the wrong RTI for the occupancy classification, undersized piping, incompatible piping materials, flexible sprinkler hoses not attached to the building structure, along with areas of the building not protected by the sprinkler system all require further investigation by a qualified ---- MFSPC.

OBSTRUCTION INVESTIGATION The presence of obstructions in sprinkler systems shall be checked every ---- years by opening a flushing connection at the end of ---- main per system 5/1 ----- sprinkler head per system toward the end of one branch line shall also be removed. This is done for investigating for the presence of foreign organic or inorganic material. 1 Sources of obstructions to piping include but are not limited to pipe scale, careless installation or repair, raw water sources, biological growth, sprinkler calcium carbonate deposits and Microbiologically Influenced Corrosion (MIC). Inorganic material would include but not be limited to silt, sand, rocks, gravel, and construction debris. Organic material includes wood, microbes, and zebra mussels When tubercules and slime are found during the investigation, they shall be tested for ---- MIC An obstruction investigation shall also be performed whenever the following conditions exist such as pinhole leaks, a record of broken public water mains in the vicinity, foreign material in water discharged during drain tests or plugging of inspector's test valve connection. A complete list of system conditions requiring obstruction investigation are listed in Chapter 14 and Annex D of NFPA #25 2011 edition. Unlike other extinguishing agents - water, dry chemical, CO2, etc., a stable aqueous foam can extinguish a flammable or combustible liquid fire by the combined mechanisms of cooling, separating the flame/ignition source from the product surface, suppressing vapors and smothering. It can also secure for extended periods of time against reflash or re-ignition. Water, if used on a standard hydrocarbon fuel, is heavier than most of those liquids and if applied directly to the fuel surface, will sink to the bottom having little or no effect on extinguishment or vapor suppression. If the liquid fuel heats above 212ºF, the water may boil below the fuel surface throwing the fuel out of the contained area and spreading the fire. Foam fire extinguishing systems shall be periodically inspected, tested and otherwise maintained in accordance with information described in this study material as well as NFPA 25 (2011), NFPA 11 (2005), as modified by Fire Code Appendix B, and NFPA 16 The Standard for Installation of FoamWater Sprinkler and Foam-Water Spray Systems (2007), as modified by Fire Code Appendix B, and manufacturers listing.

Foam is created by mixing a ----%foamite concentrate with water and air. 3 FOAM TYPES ARE SUBDIVIDED INTO THREE RANGES: 1) Low-expansion foam uses foam to solution volume ratios up to 20 to 1 2) Medium-expansion foam uses foam to solution volume ratios from 20 to 1 to 200 to 1 3) High-expansion foam use foam to solution volume ratios from to 200 to 1 to approximately 1000 to 1. It is important to note that different foam manufacturers may not produce foam solution that is compatible with each other. Great care must be exercised when testing and maintaining these systems to be certain that all the equipment is listed to be used together.
