INSTALLATION, OPERATING & SERVICING INSTRUCTIONS

All fire extinguishers should be installed, inspected and maintained in accordance with the National Fire Protection Association standard titled "Portable Fire Extinguishers", NFPA-10 and the requirements of local authorities having jurisdiction. When maintenance is indicated, it should be performed by trained persons having proper equipment. Fire extinguishers are pressure vessels and must be treated with respect and handled with care. They are mechanical devices and require periodic maintenance to be sure that they are ready to operate properly and safely. Amerex strongly recommends that the maintenance of portable fire extinguishers be done by a trained professional – your local authorized Amerex Distributor. Amerex Corporation makes original factory parts available to insure proper maintenance – USE OF SUBSTITUTE PARTS RELEASES AMEREX OF ITS WARRANTY OBLIGATIONS. Amerex parts have machined surfaces and threads that are manufactured to exacting tolerances. O-rings, hoses, nozzles, and all metal parts meet precise specifications and are subjected to multiple in-house inspections and tests for acceptability. There are substitute parts available that may be incorrectly labeled as UL component parts, some are advertised as Amerex type.

OPERATION

NOTE: Persons expected to use this extinguisher should be trained in initiating its operation and in the proper fire fighting technique. Familiarize all personnel with this information before an emergency occurs.

1. Remove extinguisher from wall hanger or vehicle bracket. 2. Hold the extinguisher upright, twist and pull ring pin, snapping the plastic lockwire seal. 3. Stand back 15 feet from the fire and aim the nozzle at base of flames nearest you. 4. Sweep side to side across the base of the fire and past both edges. Progressively follow up

until the fire is extinguished. Work the fire away from you while being alert for flashbacks. Move closer as the fire is extinguished but not so close as to scatter or splash the burning materials.

5. When the fire is out, stand by and watch for possible reignition. 6. Evacuate and ventilate the area immediately after extinguishing the fire. The fumes and

smoke from any fire may be hazardous and can be deadly.

DISCHARGE TIME – VARIES ACCORDING TO THE MODEL EFFECTIVE RANGE OF AGENT THROW IS 40-50 feet

INSPECTING THE EXTINGUISHER

PERIODIC INSPECTION PROCEDURES (Monthly or more often if circumstances dictate)

[NFPA-10] Periodic inspection of fire extinguishers shall include a check of at least the following items:

1. Location in designated place. 2. No obstruction to access or visibility. 3. Pressure gauge reading or indicator in the operable range or position. 4. Operating instructions on nameplate and facing outward. 5. Safety seals and tamper indicators not broken or missing. 6. Examination for obvious physical damage, corrosion, leakage, or clogged nozzle. 7. Determine fullness by weighing.

MAINTENANCE

[NFPA-10] At least once a year or more frequently if circumstances require, maintenance should be performed. Maintenance is a "thorough check" of the extinguisher. It is intended to give maximum assurance that a fire extinguisher will operate effectively and safely. It includes a thorough examination for physical damage or condition to prevent its operation and any necessary repair or replacement. It will normally reveal if hydrostatic testing or internal maintenance is required.

This extinguisher should be inspected at regular intervals (monthly or more often if circumstances dictate) to insure that it is ready for use. Inspection is a "quick check" that a fire extinguisher is available and is in operating condition. It is intended to give reasonable assurance that the fire extinguisher is fully charged. This is done by verifying that it is in its designated place, that it has not been actuated or tampered with, and that there is no obvious physical damage or condition to prevent its operation.

7

extinguisher with dry nitrogen to 240 psi. Nitrogen supply regulator should be set to no more than 265 psi. This will insure proper aeration of the chemical.

10. Check extinguisher for leaks by applying detecting fluid or a solution of soapy water to the nitrogen charging adapter orifice, around the collar o-ring sealing area, cylinder welds and gauge. Remove the pressurizing adapter.

11. Install ring (safety) pin and lockwire (tamper) seal. Attach new recharge tag.

12. Weigh assembled extinguisher and confirm that the total weight is within the allowable tolerances indicated in the "Maintenance" section of the nameplate (label).

TROUBLESHOOTING GUIDE

WARNING: Before attempting to correct any leakage problem, be sure that the agent cylinder and hose are completely depressurized. Check to determine the source of a leak before the extinguisher is depressurized. Leakage repairs will require depressurization and removal of the valve assembly. Depressurize by discharging into a Closed Recovery System or inverting the extinguisher. After depressurizing the extinguisher and correcting the problem, it will be necessary to clean all valve parts thoroughly.

PROBLEM CORRECTIVE ACTION 1. Leak at collar o-ring Remove valve assembly, remove and

discard o-ring, clean collar and lube lightly with Visilox V-711. Clean o-ring groove on valve and install new collar o-ring. Lubricate with Visilox V-711.

2. Leak through valve

Check valve stem seating area for scratches or foreign matter. Clean seating area with a tooth brush and soft cloth. Install new valve stem assembly.

3. Leak around gauge

Remove gauge*, clean threads and reinstall using Teflon tape on the gauge threads.

4. Defective gauge

Remove defective gauge* an install the proper Amerex pressure gauge (P/N 05225 240 psi) using Teflon tape on the gauge threads.

5. Leak in the cylinder

Contact Amerex if under warranty, otherwise mark "REJECTED" and remove from service or return to owner.

* Pressure gauge threads are coated with a special epoxy at the factory. For easy removal, soak the valve assembly in hot water (180°F) for two to four minutes. Remove gauge with a thin 7/16" open end wrench.

The terms “Shall” and “Should” are often used. Shall indicates a mandatory requirement, Should indicates a recommendation.

14 15

Determine Fire Alarm RequirementsNFPA 101 Life Safety Code determines the fire alarm requirements based on the occupancy rating of the building.

Within each occupancy chapter, section 3.4 will specify the fire alarm requirements for that occupancy class. Section 3.4 is “Detection, Alarms & Communication”. Section 3.5 is “Extinguishing Requirements”.

Section 3.4 Detection, Alarms and CommunicationThe General ProvisionSpecifies the conditions under which a fire alarm is required in that particular occupancy.

The Initiation ProvisionSpecifies how the fire alarm will be activated, other than as relates to automatic fire detection. It is typical in many occupancy chapters that the Initiation provision call for “Manual activation in accordance with 9.6.2.1”. When referred to chapter 9, only the applicable portions of chapter 9 apply for that occupancy.

The Notification ProvisionSpecifies “On Premises” signaling requirements. It may require voice evacuation, and may permit or prohibit the use of “Pre-Signal” features.

The Detection ProvisionSpecifies requirements for automatic detection.This section should always be reviewed, even if the building is not required to have a fire alarm system under the general statement for that occupancy class.

The Emergency Forces Notification ProvisionIncludes any requirement for “Off Premises” signaling (monitoring).

Section 3.5 Extinguishing RequirementsSpecifies requirements for automatic sprinkler systems. Refers to chapter 9 section 9-7 “Automatic Sprinklers and other Extinguishing Equipment”

The code may require either an, approved automatic sprinkler or an approved supervised automatic sprinkler. Where a supervised automatic sprinkler is required, NFPA 101 2009 9-7.2.1 and 9-7.2.2 are applicable.

Sprinkler System Supervision Includes:Water flowWater Supply Control ValvesFire Pump StatusWater Tank, Levels and PressuresAir Pressure on Dry Pipe SystemsBuilding Temperature

Water supply control valves shall be supervised to obtain a distinctive signal when in an off normal position, within 2 revolutions of the handwheel, or when the valve has moved one fifth from its normal position.

The switch shall not restore to a normal condition throughout the entire travel of the valve, until it is restored to a fully open position.

A Supervisory signal must be visually or audibly distinctive from both Alarm and Trouble signals.

Water flow and supervisory devices cannot be connected on the same initiating circuit so that the closing of a valve is annunciated as a “trouble” condition.

Fire Alarm SignalsA. Alarm: A signal indicating a fire emergency. 1. Automatic water flow device 2. Manual fire alarm station (pull station) 3. Automatic fire detectors (smoke or heat detectors)

B. Supervisory: A signal indicating an “off-normal” condition exists on the extinguishing system. 1. Control valve switch 2. High/low air pressure switch 3. Water tank level and temperature switches 4. Low water pressure for public water supplies 5. Low building temperature switch 6. Water Column Switch

C. Trouble: A signal indicating a problem with the fire control panel or associated wiring which may render the system inoperable.

1. Loss of primary power (120VAC) 2. Loss of secondary power (battery) 3. A defect in the supervised wiring to an initiating device, indicating appliance or extinguishing

agent release device. 4. Disabled circuit or function 5. Failure to communicate with central station

Types Of Sprinkler SystemsWet Pipe Sprinkler SystemWet systems are the most common and reliable sprinkler systems since no equipment other than the sprinkler heads are required to operate. Wet systems use automatic sprinkler heads attached to piping containing water and connected to a water supply so that water will be discharged immediately from an open sprinkler. Water will only be discharged through heads that have opened due to fire.

Dry Pipe Sprinkler SystemDry pipe systems use automatic sprinklers attached to a piping system pressurized with air. These systems use a dry pipe valve and air pressure to hold back the water supply. When the air pressure in the system bleeds off due to an open sprinkler, the water pressure will open the valve and fill the system. The water will only be discharged through the heads that have opened due to fire. Dry systems are usually installed in unheated buildings or where there is the possibility of sprinkler pipes freezing.

34 35

Installation of Valve Supervisory SwitchesThe main reason for sprinkler system failure is due to the water control valves being closed. Therefore, every water control valve that can disable any portion of a sprinkler system should be electrically supervised in the open position.

The main types of valves used are, outside screw and yoke [OS&Y], butterfly and wall or post indicator [PIV] valves.

OS&Y valves have a large handwheel with a threaded shaft through the center of the handwheel. There is also a bracket or “yoke” that runs on both sides of the threaded shaft, from the body of the valve to the handwheel. When the valve is open, the shaft protrudes through the handwheel. As the valve is closed, the shaft is being screwed into the body of the valve. Most tamper switches for these valves mount on the yoke of the valve using either “J” hooks or carriage bolts and a mounting bracket. The switches have a “trip rod” that rests in a groove on the threaded shaft of the valve. Some valve manufacturers put the groove on the stem, with other valves the installer must file a 1/8” deep groove using a 3/8” rat tail, (round not tapered), file. As the valve is closed, the trip rod rises out of the groove and trips the switch. The switch must stay tripped throughout the entire travel of the valve. It must not alternate between “tripped” and “normal” as the trip rod is rolling across the threads of the stem. The switch must also trip if the switch is removed from the valve.

Post Indicator Valves use a different switch than OS&Y valves. For PIV valves, the switch screws into a 1/2” NPT fitting on the side of the valve. The switch has a trip rod that rides on the target of the valve. The target is the portion of the valve that shows “open” or “shut”. When the valve is fully open, the target should be pushing the trip rod against the spring force of the rod. As the valve is closed, the spring force causes the rod to follow the target of the valve, tripping the switch.

Butterfly Valves use the same switch as PIV valves. It also screws into a 1/2” NPT fitting on the valve. The trip rod is operated by a cam inside of the valve that rotates as the valve is closed. Partially close the valve, remove the nipple from the switch and screw it into the valve. Loosen the set screw that holds the trip rod in the housing and extend the trip rod. Slide the PCVS over the nipple, observing which direction the rod will move when the valve is closed. Orient the device so the cam of the valve is pushing against the spring force of the PCVS when the valve is open. As the trip rod touches the cam, it will push the trip rod back into the housing. If the trip rod is too long, remove the rod from the switch housing, note that there is a groove cut into the rod 1” from the end of the rod that was in the housing, this can be broken off with a pair of pliers. After the cam of the valve pushes the trip rod back into the housing, remove the PCVS and slide the trip rod 1/32” farther into the housing before tightening the set screw. This will prevent any imperfections on the cam from affecting the operation of the PCVS. Slide the PCVS over the nipple and tighten the set screw.

Ball Valves. The Potter Model RBVS can be used to supervise ball valves.

Special Valves. For non-rising stem valves a “plug type switch” can be used. These are switches that are UL listed for special applications and are subject to the approval of the authority having jurisdiction. A receptacle is mounted on a wall or section of pipe, a plug with a length of cable is plugged into the receptacle. The other end of the cable is looped through the handwheel of the valve or through a hole drilled into the handle of the valve, then hard wired back into the receptacle. When the valve is closed it unplugs the plug from the receptacle and trips a switch. If the cable is cut it also opens the circuit. The cable must be stretched tight enough so operation of the valve will cause the plug to pull out of the receptacle.

Note: Valve supervisory switches shall trip within 2 revolutions of the handwheel, or 1/5 of the travel of the valve, per NFPA72 2010 17.16.1.2.

Other Types of SupervisionLow Water Supply PressureLoss of water supply pressure in the sprinkler supply mains can be monitored with a supervisory pressure switch. Care must be taken to adjust the pressure switch below the lowest pressure available during peak demand periods to avoid nuisance alarms.

Fire PumpsFire pumps are automatically started in the event of water flow in a sprinkler system in order to supply more water pressure to the system. Power to an electric pump should be supervised for loss of phase or phase reversal. A pump running signal can be obtained by installing a pressure switch in the discharge line of the pump.

Pressure TanksThese tanks are pressurized waster reservoirs used to supply a limited amount of water for sprinkler systems. The tanks are usually located above the highest sprinkler heads under the main roof, or in a heated room on the roof. Each tank is kept 2/3 full of water with a maintained pressure of approximately 75 psi in the tank.Supervision includes: Water level, low and high pressure, low temperature, and water control valves.

Gravity Water TanksGravity tanks are tower or roof mounted reservoirs and can immediately supply a large volume of water for sprinkler systems. The tank may have a heating element to prevent freezing.Supervision includes: Water level, low temperature, and water control valves.

Building TemperatureIt is recommended that premises protected by wet sprinkler systems, or the room that a dry pipe valve is located in, be monitored for low temperature of 40° F. This will prevent sprinkler pipes or dry pipe valves from freezing should the building heating equipment fail.

Test ProceduresWaterflow Switches - Wet Pipe SystemsVane TypeThere should be a valve downstream of the flow switch, preferably at the far end of the system, but it may be immediately after the flow switch. The valve should be marked Inspectors Test Valve per NFPA13 2010 6.7.4.1. The valve should also have a reduced orifice equal to the smallest sprinkler on the system per NFPA13 2010 8.17.4.2.1. The output of the valve should be piped to a spot where it will not cause any water damage.

Open the valve and allow the water to flow, after the retard time expires, the switch will trip. If the device does not operate check to make sure 10 gpm is flowing out of the test valve. If possible, place a 5 gallon bucket under the output of the valve. If the bucket can be filled in 30 seconds then the valve is flowing 10 gpm.

If a hose needs to be connected to the test valve to prevent water damage, the hose should be 5/8” ID, and as short as possible to reduce friction loss.

If the device still does not trip it may be installed too close to a valve or change in direction of pipe which is causing turbulence or back pressure in the water, or paddle may have been trimmed. Never trim the paddle.

Pressure TypeThe preferred method is to open the inspectors test valve at the end of the system similar to the method for test-ing vane type flow switches. This test also causes the clapper of the alarm valve to open.

Another test method is to open the normally closed alarm by-pass valve that connects the supply water directly to the pressure switch. This is usually a 1/2” or 3/4” ball valve. On most systems there will be two ball valves between the pressure switch and the alarm valve. One of these is the normally closed by-pass valve that is only opened for testing. The other valve is a normally open alarm shut off valve. It is used to either silence the pres-sure switch in an actual alarm or to disable it if water must be flowed into the system.

The pressure switch should be installed on top of a retard chamber or a pressure switch with a built-in retard should be used. If the switch is installed on top of the retard chamber, it will activate as soon as the retard chamber fills. The time delay provided by a retard chamber will vary depending on the water supply pressure at the time. The time delay provided by a pressure switch with a built-in retard will remain constant. As long as the pressure at the switch is at least 6 psi, the switch will trip after the retard times expires.

An uninsulated section of a single conductor should not be looped around the terminal and serve as two separate connections. The wire must be severed, thereby providing supervision of the connection in the event that the wire becomes dislodged from under the terminal.

Use teflon tape sealant only. Apply only to male threads of connectors.

Use of pipe cement voids warranty as this material may obstruct pressure aperture resulting in loss of alarm signal.

Device must be installed before any shut off valve on alarm port line unless it is supervised by a supervisory switch such as Potter Model RBVS.

The system should be tested on a quarterly basis or more frequently to insure proper operation.

Due to the possibility of unintended discharges caused by pressure surges, trapped air, or short retard times, waterflow switches that are monitoring wet pipe sprinkler systems shall not be used as the sole initiating device to discharge AFFF, deluge, or chemical suppression systems.
