GeneralDescriptionThe Model AV-1-300 Alarm CheckValves are divided seat ring, rubberfaced clapper, waterflow alarm checkvalves that are intended for use in wetpipe (automatic sprinkler) fire protec-tion systems. They may be installedvertically or horizontally*, and they aredesigned to automatically actuateelectric and/or hydraulic alarms whenthere is a steady flow of water into thesystem that is equivalent to the dis-charge rate of one or more sprinklers.
A separately ordered, Model RC-1 Re-tard Chamber (TFP920) is required forinstallations subject to variable pres-sures. It is used to help prevent falsealarms associated with pressure vari-ations in public water supplies.
The AV-1-300 Alarm Check ValveTrim includes pressure gauges tomonitor system pressure conditions, aby-pass check valve, a main drainvalve, and an alarm test valve. Thebypass check valve reduces the pos-sibility of false alarms by permittingslow as well as small transient in-creases in water supply pressure to bepassed through to the system withoutopening the waterway clapper.
WARNINGThe Model AV-1-300 Alarm CheckValves described herein must be in-stalled and maintained in compliancewith this document, as well as with theapplicable standards of the NationalFire Protection Association, in additionto the standards of any other authori-ties having jurisdiction. Failure to doso may impair the integrity of thesedevices.
The owner is responsible for maintain-ing their fire protection system and de-vices in proper operating condition.The installing contractor or manufac-turer should be contacted relative toany questions.

TechnicalDataApprovals:UL and C-UL Listed, as well as FMApproved.
Working Water Pressure Range20 to 300 psi (1,4 to 20,7 bar).
Friction LossRefer to Graph A.
Physical CharacteristicsThe body is ductile iron, the handholecover is ductile iron or cast iron, andthe seat ring is bronze. The clapper forthe 2-1/2 inch (DN65) valve size isstainless steel. The clapper for thelarger valve sizes is either cast or duc-tile iron. All valve sizes utilize anEPDM clapper facing.
Flanged connections are availabledrilled per ANSI, ISO, AS, and JISspecifications as detailed in Table A.
Threaded port connections for theAV-1-300 Valves are available NPTthreaded or threaded per ISO 7/1 asdetailed in the Ordering Proceduresection. Valves with NPT threadedports will readily accept the trim ar-rangements detailed in Figures 4through 6.
OperatingPrinciplesWhen the fire protection system is in-itially being pressurized, water will flowinto the system until the water supplyand system pressure become equal-ized, and the torsion Spring closes theClapper in the Alarm Check Valve.Once the pressures have stabilized,the Alarm Check Valve is in serviceand the centrally located groove in theSeat Ring is sealed. Consequently,with the Alarm Check Valve set forservice, there is no flow through thealarm port to the alarm devices (i.e.,water motor alarm and/or pressurealarm switch).
When there is a steady flow of waterinto the sprinkler system due to asprinkler operation, the Clapper opensas shown in Figure 2. Water is thenpermitted to flow into the centrally lo-cated groove in the Seat Ring and outthrough the alarm port towards the Re-striction Assembly (Figure 3). Whenthe flow through the inlet restriction ofthe Restriction Assembly exceeds theflow through the outlet restriction, theRetard Chamber (where provided inthe case of systems with variable pres-sure), begins to fill. Subsequently, the
water motor alarm and/or the pressurealarm switch will be actuated. Thealarms will continue to be actuated aslong as the Clapper remains opened.Water in the alarm lines will automat-ically drain out through the 1/8 inch(3,2 mm) drain orifice in the RestrictionAssembly (Figure 3) when the Clappercloses (due to a discontinuation in theflow of water into the sprinkler sys-tem).
In the case of variable pressure sys-tems, slow as well as small transientincreases in water supply pressuremay continue to be built up in the sys-
tem (via the bypass check valve) with-out opening the Clapper. A transientsurge in supply pressure which is suf-ficient to only momentarily open theClapper will not cause a false alarm,and a portion of the increase in pres-sure will be trapped within the system,thus reducing the possibility of anotheropening. Any water in the alarm line isautomatically drained, further reduc-ing the possibility of a false alarm dueto a successive transient surge in sup-ply pressure.

Design CriteriaIn planning the installation, considera-tion must be given to the disposal ofthe large quantities of water that maybe associated with draining the systemor performing a flow test.
Valves installed in the vertical positionmust have the flow going up. Valvesinstalled in the horizontal position mustbe positioned so that the drain connec-tion points down.
The sprinkler system designer must beaware that the configuration of the pip-ing network and its tendency to trappockets of air (such as in the case of apeaked-roof gridded system) can af-fect the performance of the alarm sys-tem. Although a slight amount oftrapped air is desirable to prevent sig-nificant pressure increases due tothermally induced expansion of thewater, a large quantity of trapped air ina system may result in the possibilityof an intermittent alarm.
The possibility of an intermittent alarmcondition is a consequence of the factthat the flow out of the system throughthe test valve or a single sprinkler isvery small relative to the flow that canbe passed through the valve. This dif-ference increases with valve size. Ifthe system were free of trapped air,flow in would equal flow out and theClapper would always stabilize atsome open position (as needed to ac-commodate the required flow). Withtrapped air in the system, however, theClapper first opens wider since thesystem initially demands greater flowuntil the air pockets are compressed(back to nearly the supply pressure),and then it will tend to return closer tothe Seat Ring. If the volume of the airpockets is excessive, flow into the sys-tem can be momentarily reduced tonearly zero (once the air pockets arecompressed) and the Clapper mayclose, causing flow to the alarms to beshutoff.
Once the Clapper has closed, suffi-cient water must flow out of the systembefore the Clapper will again open. Arepetition of the above described con-dition is termed an intermittent alarm.
Using a vent (which can also serve asan end-of-line Inspector’s Test Con-nection) piped from the top of a crossmain or end of a branch line at thepoint most remote from the alarmvalve, and filling the system slowly inaccordance with the steps describedin the Setting Procedure section, canprevent an excessive amount of airfrom being trapped.
InstallationNOTES
Proper operation of the Model AV-1-300 Alarm Check Valves dependsupon the trim described in this datasheet being installed in accordancewith the following instructions. Failureto follow the appropriate trim installa-tion instructions may prevent the de-vice from functioning properly as wellas void listings/approvals, and themanufacturer’s warranties.
The Alarm Check Valves must be in-stalled in readily visible and accessiblelocations.
It is recommended that provision bemade for viewing the alarm line drainwater by locating the main drain outletin a readily visible area.
Wet pipe fire protection systems mustbe maintained at a minimum tempera-ture of 40°F/4°C.
Step 1. Trim the Alarm Check Valve inaccordance with Figure 4, 5, or 6, asapplicable. Apply pipe thread sealantsparingly to male threads only.
Step 2. The Alarm Vent Trim illus-trated in Figure 8 must be installed if awater motor alarm is not to be used.
Step 3. Plug unused alarm connec-tions.
Step 4. Suitable provision must bemade for disposal of alarm line andsystem drainage water. Drainagewater must be directed so that it willnot cause damage or result in danger-ous conditions.
Step 5. The alarm line drain must bearranged so that there will be no dan-ger of freezing.
Step 6. The check valve in the exter-nally mounted bypass around the wa-terway Clapper must be installed withits arrow pointed up, and the draincheck valve must be installed with itsarrow pointing towards the drain.
Step 7. It is recommended that a ventconnection (which may also be usedas an end-of-line Inspector’s TestConnection), be piped from a crossmain or branch line at the point mostremote from the alarm valve. The ventline should be connected to the top ofa cross main or to the end of a branchline and be located at the highest levelof a multi-level installation.
The vent connection can be used tobleedoff excessive air from the sys-tem, and therefore, minimize the pos-sibility of a false alarm due to a tran-sient surge in supply pressure. Thecontraction/expansion associated withan excessive amount of trapped air
could also cause the waterway Clap-per to cycle open and shut during aninspector’s test or during a dischargeby a single sprinkler.

SettingProcedureSteps 1 through 11 are to be per-formed when initially setting the ModelAV-1-300 Alarm Check Valve or aftersystem operation due to a fire.
Step 1. Open the 1/4 inch Gauge TestValves for the Supply and SystemPressure Gauges.
Step 2. Check to see that the Hand-hole Cover bolts are tight. If not, cross-tighten them.
Step 3. Close the Alarm Test Valve.
Step 4. Open the remote cross mainor branch line vent connection (Ref.Step 7 in the Installation section).
Step 5. Slowly open the main controlvalve until the sound of flowing waterjust begins and then open the valveone more turn.
NOTEFilling the system with water will resultin operation of the associated alarms.Consequently, notification must firstbe given to the owner and fire depart-ment, central station, or other signalstation to which the alarms are con-nected.
Step 6. Close the remote branch linevent connection after the discharge ofaerated water ceases, and the outlethas flowed full for at least 15 seconds.
Step 7. Fully open the main controlvalve.
Step 8. Open the end-of-line Inspec-tor’s Test Connection (or Alarm TestValve, if acceptable to the authorityhaving jurisdiction) and verify that thesystem alarms operate.
NOTENotify the proper authorities and allpersonnel who may be affected that analarm test is to be performed.
Step 9. Close the end-of-line Inspec-tor’s Test Connection (or Alarm TestValve).
Step 10. Verify that water ceases toflow from the alarm line drain. If watercontinues to flow, follow the correctiveprocedure described in the Mainte-nance and Service section.
NOTEThe Restriction Assembly has a 1/8inch (3,2 mm) diameter drain orifice.Sufficient time must be allowed fordrainage of the Retard Chamber andthe piping to the water motor alarm.
Step 11. Once it has been verified thatthe flow of water out of the alarm linedrain has stopped, the alarm valve isset and is ready for service.
NOTEAfter placing a fire protection systemin service, notify the proper authoritiesand advise those responsible for moni-toring proprietary and/or central sta-tion alarms.
Care andMaintenanceThe following procedures and inspec-tions should be performed as indi-cated, in addition to any specific re-quirements of the NFPA. Anyimpairment must be immediately cor-rected.
The owner is responsible for the in-spection, testing, and maintenance oftheir fire protection system and de-vices in compliance with this docu-ment, as well as with the applicablestandards of the National Fire Protec-tion Association (e.g., NFPA 25), inaddition to the standards of anyauthority having jurisdiction. The in-stalling contractor or product manufac-turer should be contacted relative toany questions.
It is recommended that automaticsprinkler systems be inspected,tested, and maintained by a qualifiedInspection Service.
The Model AV-1-300 Alarm Check
Valves do not require any regularlyscheduled maintenance. It is recom-mended, however, that proper opera-tion of the alarms be periodically veri-fied in accordance with a procedurethat is acceptable to the authority hav-ing jurisdiction. Any impairment mustbe immediately corrected.
NOTEPerforming the care and maintenanceprocedures will result in operation ofthe associated alarms. Consequently,notification must first be given to theowner and fire department, central sta-tion, or other signal station to which thealarms are connected.
Before closing a fire protection systemmain control valve for maintenancework on the fire protection systemsthat it controls, permission to shutdown the affected fire protection sys-tems must first be obtained from theproper authorities, and all personnelwho may be affected by this decisionmust be notified.
Inspection ProcedureIt is recommended that the followinginspection procedure be performed atleast quarterly by a qualified Inspec-tion Service:
Step 1. Notify the proper authoritiesand all personnel who may be affectedthat an alarm test is to be performed.
Step 2. Open the end-of-line Inspec-tor’s Test Connection (or Alarm TestValve, if acceptable to the authorityhaving jurisdiction) and verify that thesystem alarms operate in accordancewith the requirements of the authorityhaving jurisdiction. Verify that thewater motor alarm and/or the pressurealarm switch properly actuate andwithin the elapsed time required by theauthority having jurisdiction.
Step 3. Verify that water is flowing outof the alarm line drain at a rate consis-tent with the 1/8 inch (3,2 mm) diame-ter drain orifice in the Restriction As-sembly.
Step 4. Close the end-of-line Inspec-tor’s Test Connection (or Alarm TestValve).
Step 5. Verify that water ceases to flowfrom the alarm line drain.
Step 6. Clean the 1/2 inch Strainer(located in the valve trim) as well asthe 3/4 inch Strainer (located at theconnection to the water motor alarm,as applicable). Be sure to replace thestrainer baskets and tighten the capssecurely.
NOTECleaning of the Strainers after eachoperation of the alarms is especially

important in the case of water supplies(such as lakes and rivers) having alarge quantity of suspended matter. Aclogged alarm line can prevent opera-tion of the alarms.
Step 7. Notify all authorities responsi-ble for monitoring the installation thatthe fire protection system has beenreturned to service.
Sprinkler System Drain-DownDraining the sprinkler system must bedone in accordance with the followingprocedure:
Step 1. Close the main control valve,if this has not already been done.
Step 2. Open the remote cross mainor branch line vent connection (Ref.Step 7 in the Installation section).
Step 3. Open the Main Drain Valve.Check first to see that the drainagewater discharge will not cause damageor result in dangerous conditions.
Step 4. Wait until the Supply PressureGauge reads zero pressure and thesound of draining water has stoppedbefore performing any maintenancework on the fire protection system.
Leakage from Alarm Line DrainFollow the steps indicated below untilwater ceases to flow from the alarmline drain. Check for the discontinu-ation of the leakage after each step iscomplete.
Step 1. Open the Main Drain Valve.Let the water flow for about 5 secondsand then close the Main Drain Valve.This should flush any loose debris thatmay have become trapped betweenthe Clapper Facing and the Seat Ringor in the seating area of the DrainValve.
Step 2. Repeat Step No. 1 if the rateof continued flow out of the drain wasnoticeably reduced.
Step 3. Open the Alarm Test Valveand allow water to flow for about 5seconds before re-closing the valve.This should flush any loose debris thatmay have become trapped in the seat-ing area of the Alarm Test Valve.
Step 4. Repeat Step No. 3 if the rateof continued flow out of the drain wasnoticeably reduced.
Step 5. Determine whether the wateris flowing from the Alarm Port (Figure1) or past the Alarm Test Valve. If theleakage is past the Alarm Test Valve,close the main control valve, and thenrepair or replace the Alarm Test Valveas necessary.
Step 6. If it appears that the leakage
noted in Step No. 5 is from the AlarmPort, drain the system in accordancewith the prescribed procedure. Afterthe system has been drained, removethe Handhole Cover.
While holding the Spring down by thecoils, remove the Hinge Pin. Removethe Spring and Clapper Assembly).
Step 7. Using a light, check for andremove any debris that may have be-come lodged within the Seat Ringgroove. Inspect the Seat Ring seat forany damage. If the Seat Ring has be-come dented across the seat then theAlarm Check Valve will have to bereplaced. It is impractical to re-face aSeat Ring in the field.
Step 8. Check for and remove anydebris that may have become lodgedin the Clapper Facing. If a minor imper-fection remains in the Clapper Facing,then turn it over after thoroughly clean-ing both surfaces with a clean cloth.Replace the Clapper Facing if neces-sary. Be sure to securely re-tighten theretaining fastener for the ClapperWasher.
Step 9. Replace the Spring and Clap-per Assembly as shown in Figure 1.While holding the coils of the Springdown, re-insert the Hinge Pin. Be surethat the Hinge Pin is pushed all the wayto the rear of the valve.
Step 10. Replace the Handhole Cover.Return the Alarm Valve to operation inaccordance with the steps describedin the Setting Procedure section.
Clogged Alarm Line DrainIf water either does not flow or onlydribbles out of the alarm line drainduring an alarm test, then it is likelythat the screen protecting the Restric-tion Assembly drain orifice (Ref. Fig-ure 3) has become clogged.
NOTEA clogged alarm line drain will increasethe likelihood of a false alarm in thecase of a variable pressure system.
First break the union downstream ofthe Drain Restriction and remove theDrain Restriction for cleaning by back-flushing the screen. Re-install theDrain Restriction and re-assemble thedrain line.
Loss of Excess System PressureIn the case of a variable pressure sys-tem, the System Pressure Gaugeshould normally indicate a pressuregreater than that shown by the SupplyPressure Gauge. Also, the valueshould be close to that of the peaksupply pressure that has occurred af-ter the system was placed in service.
NOTELoss of excess system pressure willincrease the likelihood of a false alarmin the case of a variable pressure sys-tem.
Follow the procedure indicated belowto correct a loss of excess systempressure condition.
Step 1. Check for signs of continuedleakage from the alarm line drain. Ifrust stains and/or water deposits indi-cate that continued leakage has beentaking place, take corrective action ac-cording to the procedure described inthe sub-section entitled “LeakageFrom Alarm Line Drain”.
Step 2. If there are no signs of contin-ued leakage from the alarm line drain,close the main control valve, slowlyremove the plug from the supply pres-sure gauge test valve to relieve thesupply pressure, and then slowly openthe union in the externally mountedbypass.
Check for leakage past the BypassCheck Valve. If there is leakage, de-bris may have become lodged be-tween its clapper and seat. Drain thesystem in accordance with the pre-scribed procedure and then clean orreplace the Bypass Check Valve asrequired.
Re-assemble the externally mountedbypass, replace the plug into theGauge Test Valve, and return the fireprotection system to operation in ac-cordance with the steps described inthe Operating Procedure section.
Step 3. If there are no signs of leakagepast either the Alarm Check ValveClapper per Step 1 or the BypassCheck Valve per Step 2, inspect thesprinkler system for leakage.
Excess Pressure Due To ThermalExpansionWet pipe sprinkler systems subject toambient temperatures in excess of100°F/38°C can experience signifi-cant increases in system pressure dueto the thermal expansion of the water.In particular, a gridded wet-pipe sys-tem with a relatively small air pocketand no relief valve can be subjected toan increase of more than 100 psi (6,9bar), due to an increase in ambienttemperature of approximately50°F/28°C.
As necessary, install a pressure reliefvalve, in accordance with the require-ments of the authority having jurisdic-tion, to automatically relieve the ex-cess pressure which could otherwisebe created in wet-pipe systems thatare exposed to significant increases inambient temperature.

False AlarmsIf repeated false alarms occur in a vari-able pressure system:
Step 1. Check for and correct thecause of continued leakage out thealarm line drain.
Step 2. Check for and clean a cloggedalarm line drain.
Step 3. Check for and correct thecause of a loss in excess system pres-sure.
Step 4. Drain the sprinkler system andre-fill it in accordance with the stepsdescribed in the Setting Proceduresection.
Intermittent AlarmsIf the pressure alarm switch gives asteady signal, but the water motor gen-erates an intermittent alarm, check forbinding in the water motor alarm driveshaft.
If the water motor alarm and/or thepressure alarm switch provide an in-termittent alarm, it is likely the conse-quence of an excessive amount of airbeing trapped within the sprinkler sys-tem. Drain down the sprinkler systemand re-fill it in accordance with thesteps described in the Setting Proce-dure section.
A discontinuance of an alarm may alsobe caused by the Clapper closing dueto a sudden drop in supply pressure orthe shut-off of a pump in the supplyline. These types of problems can onlybe corrected by maintaining a steadysupply pressure.
