Model AV-1-300 Alarm Check Valve, 300 psi (20,7 bar)
2-1/2, 4, 6 & 8 Inch (DN65, DN100, DN150 & DN200)
Vertical or Horizontal* Installation

General
Description

The TYCO Model AV-1-300 Alarm
Check Valves are divided seat ring,
rubber-faced clapper, waterow alarm
check valves that are intended for
use in wet pipe (automatic sprinkler)
re protection systems. They may be
installed vertically or horizontally*,
and they are designed to automati­cally actuate electric and/or hydraulic
alarms when there is a steady ow of
water into the system that is equivalent
to the discharge rate of one or more
sprinklers.

A separately ordered Model RC-1
Retard Chamber (Ref. Technical Data
Sheet TFP920) is required for installa­tions subject to variable pressures. It is
used to help prevent false alarms asso­ciated with pressure variations in public
water supplies.

The AV-1-300 Alarm Check Valve Trim
includes pressure gauges to monitor
system pressure conditions, a bypass
check valve, a main drain valve, and
an alarm test valve. The bypass check
valve reduces the possibility of false
alarms by permitting slow as well as
small transient increases in water sup­ply pressure to be passed through to
the system without opening the water­way cla p p e r.

NOTICE

The TYCO Model AV-1-300 Alarm
Check Valves described herein must
be installed and maintained in com­pliance with this document, as well as
with the applicable standards of the
National Fire Protection Association
(NFPA), in addition to the standards of
any authorities having jurisdiction. Fail­ure to do so may impair the integrity of
these devices.

The owner is responsible for main­taining their fire protection system
and devices in proper operating
condition. Contact the installing con­tractor or product manufacturer with
any questions.

Operation

When the re protection system is ini­tially pressurized, water ows into the
system until the water supply and sys­tem pressure become equalized, and
the torsion Spring closes the Water­way Clapper in the Alarm Check Valve.
Once the pressures stabilize, the Alarm
Check Valve is in service and the cen­trally located groove in the Seat Ring is
sealed. Consequently, with the Alarm
Check Valve set for service, there is
no ow through the alarm port to the
alarm devices (i.e., water motor alarm
and/or pressure alarm switch).

When there is a steady ow of water
into the sprinkler system due to a sprin­kler operation, the Waterway Clapper
opens as shown in Figure 2. Water is
then permitted to ow into the centrally
located groove in the Seat Ring and
out through the alarm port towards the
Restriction Assembly (Figure 3). When
the ow through the Inlet Restriction of
the Restriction Assembly exceeds the
ow through the Outlet Restriction, the
Retard Chamber (where provided for
systems with variable pressure), begins
to ll.

Subsequently, the Water Motor Alarm
and/or the pressure alarm switch will
be actuated. The alarms will continue
to be actuated as long as the Water­way Clapper remains open. Water in
the alarm lines will automatically drain
out through the 1/8 inch (3,2 mm) Drain
Orice in the Restriction Assembly
(Figure 3) when the Waterway Clap­per closes (due to a stop in the ow of
water into the sprinkler system).

For variable pressure systems, slow
as well as small transient increases in
water supply pressure may continue to
build up in the system (via the Bypass
Check Valve) without opening the
Waterway Clapper.

A transient surge in supply pres­sure that is sufcient only to open the
Waterway Clapper momentarily will not
cause a false alarm, and a portion of
the increase in pressure will be trapped
within the system, thus reducing the
possibility of another opening. Any
water in the alarm line is automatically
drained, further reducing the possibil­ity of a false alarm due to a successive
transient surge in supply pressure.

Design
Criteria

In planning installation of the TYCO
Model AV-1-300 Alarm Check Valves,
consideration must be given to the dis­posal of the large quantities of water
that may be associated with draining
the system or performing a ow test.

RESTRICTION ASSEMBLY

(Provided with Alarm Check Valve Trim)

Valves installed in the vertical position
must have the ow going up. Valves
installed in the horizontal position must
be positioned so that the drain connec­tion points down.

The sprinkler system designer must
be aware that the conguration of
the piping network and its tendency
to trap pockets of air (such as in the
case of a peaked-roof gridded sys­tem) can affect the performance of the
alarm system. Although a slight amount
of trapped air is desirable to prevent
signicant pressure increases due to
thermally induced expansion of the
water, a large quantity of trapped air in
a system may result in the possibility of
an intermittent alarm.

The possibility of an intermittent alarm
condition is a consequence of the fact
that the ow out of the system through
the test valve or a single sprinkler is
very small relative to the ow that can
be passed through the valve. This dif­ference increases with valve size. If the
system were free of trapped air, ow in
would equal ow out and the Waterway
Clapper would always stabilize at some
open position (as needed to accommo­date the required ow). With trapped
air in the system, however, the Water­way Clapper rst opens wider since the
system initially demands greater ow
until the air pockets are compressed
(back to nearly the supply pressure),
and then it will tend to return closer

TFP910

Page 5 of 20

to the Seat Ring. If the volume of the
air pockets is excessive, ow into the
system can be momentarily reduced
to nearly zero (once the air pockets
are compressed) and the Waterway
Clapper may close, causing ow to the
alarms to be shutoff.

After the Waterway Clapper has
closed, sufcient water must ow out
of the system before the Waterway
Clapper will again open. A repetition
of the above described condition is
termed an intermittent alarm.

Using a vent (which can also serve
as an end-of-line Inspector’s Test
Connection) piped from the top of a
cross main or end of a branch line at
the point most remote from the alarm
valve, and lling the system slowly in
accordance with the steps described in
the Setting Procedure section, can pre­vent an excessive amount of air from
being trapped.

Installation

NOTICE

Proper operation of the TYCO Model
AV-1-300 Alarm Check Valves depends
upon the trim described in this data
sheet installed in accordance with the
following instructions. Failure to fol­low the appropriate trim installation
instructions may prevent the device
from functioning properly as well as
void listings/approvals and the manu­facturer’s warranties.

The Alarm Check Valves must be
installed in readily visible and acces­sible locations.

It is recommended that provision be
made for viewing the alarm line drain
water by locating the main drain outlet
in a readily visible area.

Wet pipe fire protection systems must
be maintained at a minimum tempera­ture of 40°F (4°C).

Step 1. Trim the Alarm Check Valve in
accordance with Figure 4, 5, or 6, as
applicable. Apply pipe-thread sealant
sparingly to male threads only.

Step 2. The Alarm Vent Trim illustrated
in Figure 8 must be installed if a water
motor alarm is not to be used.

Step 3. Plug unused alarm
connections.

Step 4. Suitable provision must be
made for disposal of alarm line and
system drainage water. Drainage
water must be directed so that it will
not cause damage or result in danger­ous conditions.

Step 5. The alarm line drain must be
arranged so that there will be no dan­ger of freezing.

Step 6. The check valve in the exter­nally mounted bypass around the
Waterway Clapper must be installed
with its arrow pointed up, and the drain
check valve must be installed with its
arrow pointing towards the drain.

Step 7. It is recommended that a vent
connection (which may also be used
as an end-of-line Inspector’s Test
Connection), be piped from a cross
main or branch line at the point most
remote from the alarm valve. The vent
line should be connected to the top of
a cross main or to the end of a branch
line and be located at the highest level
of a multi-level installation.

The vent connection can be used to
bleed-off excessive air from the sys­tem, and therefore, minimize the
possibility of a false alarm due to a
transient surge in supply pressure. The
contraction/expansion associated with
an excessive amount of trapped air
could also cause the Waterway Clap­per to cycle open and shut during an
inspector’s test or during a discharge
by a single sprinkler.

Setting
Procedure

Steps 1 through 11 are to be performed
when initially setting the Model AV-1­300 Alarm Check Valve or after system
operation due to a re.

NOTICE

Filling the system with water will result
in operation of the associated alarms.
Consequently, notification must first be
given to the owner and fire department,
central station, or other signal station to
which the alarms are connected.

Notify the proper authorities and all
personnel who may be affected that
an alarm test is to be performed.

After placing a fire protection system
in service, notify the proper authorities
and advise those responsible for moni­toring proprietary and/or central station
alarms.

Step 1. Open the 1/4 inch Gauge Test
Valves for the Supply and System Pres­sure Gauges.

Step 2. Check to see that the Hand­hole Cover bolts are tight. If not,
cross-tighten them.

Step 3. Close the Alarm Test Valve.
Step 4. Open the remote cross main or

branch line vent connection. (Refer to
Step 7 in the Installation section.)

Step 5. Slowly open the main control
valve until the sound of owing water
just begins and then open the valve
one more turn.

Step 6. Close the remote branchline
vent connection after the discharge of
aerated water ceases, and the outlet
has owed full for at least 15 seconds.

Step 7. Fully open the main control
valve.

Step 8. Open the end-of-line Inspec­tor’s Test Connection (or Alarm Test
Valve, if acceptable to the authority
having jurisdiction) and verify that the
system alarms operate.

Step 9. Close the end-of-line Inspec­tor’s Test Connection (or Alarm Test
Valve).

Step 10. Verify that water ceases to
ow from the alarm line drain. If water
continues to ow, follow the corrective
procedure described in the Care and
Maintenance section.

The Restriction Assembly has a 1/8
inch (3,2 mm) diameter drain orice.
Sufcient time must be allowed for
drainage of the Retard Chamber and
the piping to the water motor alarm.

Step 11. After verication that the ow
of water out of the alarm line drain has
stopped, the alarm valve is set and is
ready for service.

Care and
Maintenance

The following procedures and
inspections should be performed in
accordance with this section, in addi­tion to any specic requirements of the
NFPA. Any impairment must be imme­diately corrected.

NOTICE

Performing the care and maintenance
procedures will result in operation of
the associated alarms. Consequently,
notification must first be given to the
owner and fire department, central sta­tion, or other signal station to which the
alarms are connected.

Before closing a fire protection system
main control valve for maintenance
work on the fire protection system
that it controls, obtain permission to
shut down the affected fire protection
system from the proper authorities
and notify all personnel who may be
affected by this decision.

The owner is responsible for the
inspection, testing, and maintenance of
their re protection system and devices
in compliance with this document, as
well as with the applicable standards
of the National Fire Protection Asso­ciation (e.g., NFPA 25), in addition to
the standards of any other authorities
having jurisdiction. Contact the install­ing contractor or product manufacturer
regarding any questions.

Automatic sprinkler systems are rec­ommended to be inspected, tested,
and maintained by a qualied Inspec­tion Service in accordance with local
requirements and/or national codes.

The TYCO Model AV-1-300 Alarm
Check Valves do not require any reg­ularly scheduled maintenance. It is
recommended, however, that proper
operation of the alarms be periodically
veried in accordance with a proce­dure that is acceptable to the authority
having jurisdiction. Any impairment
must be immediately corrected.

Inspection Procedure

It is recommended that the following
inspection procedure be performed at
least quarterly by a qualied Inspection
Service.

Step 1. Notify the proper authorities
and all personnel who may be affected
that an alarm test is to be performed.

Step 2. Open the end-of-line Inspec­tor’s Test Connection (or Alarm Test
Valve, if acceptable to the authority
having jurisdiction) and verify that the
system alarms operate in accordance
with the requirements of the authority
having jurisdiction. Verify that the water
motor alarm and/or the pressure alarm
switch properly actuate and within the
elapsed time required by the authority
having jurisdiction.

Step 3. Verify that water is owing
out of the alarm line drain at a rate
consistent with the 1/8 inch (3,2 mm)
diameter drain orice in the Restriction
As s embl y.

Step 4. Close the end-of-line Inspec­tor’s Test Connection (or Alarm Test
Valve).

Step 5. Verify that water ceases to ow
from the alarm line drain.

Step 6. Clean the 1/2 inch Strainer
(located in the valve trim) as well as
the 3/4 inch Strainer (located at the
connection to the water motor alarm,
as applicable). Be sure to replace the
strainer baskets and tighten the caps
securely.

NOTICE

Cleaning of the Strainers after each
operation of the alarms is especially
important in the case of water sup­plies (such as lakes and rivers) having
a large quantity of suspended matter. A
clogged alarm line can prevent opera­tion of the alarms.

Step 7. Notify all authorities responsi­ble for monitoring the installation that
the re protection system has been
returned to service.

Sprinkler System Drain-Down

Draining the sprinkler system must be
done in accordance with the following
procedure:

Step 1. Close the main control valve, if
this has not already been done.

Step 2. Open the remote cross main or
branch line vent connection. (Refer to
Step 7 in the Installation section.)

Step 3. Open the Main Drain Valve.
Check rst to see that the drainage
water discharge will not cause dam­age or result in dangerous conditions.

Step 4. Wait until the Supply Pressure
Gauge reads zero pressure and the
sound of draining water has stopped
before performing any maintenance
work on the re protection system.

Leakage from Alarm Line Drain

Follow the steps indicated below until
water ceases to ow from the alarm
line drain. After each step check if leak­age has stopped.

Step 1. Open the Main Drain Valve. Let
the water ow for about 5 seconds and
then close the Main Drain Valve. This
should ush any loose debris that may
have become trapped between the
Clapper Facing and the Seat Ring or
in the seating area of the Drain Valve.

Step 2. Repeat Step 1 if the rate of
continued ow out of the drain was
noticeably reduced.

Step 3. Open the Alarm Test Valve and
allow water to ow for about 5 seconds
before re-closing the valve. This should
ush any loose debris that may have
become trapped in the seating area of
the Alarm Test Valve.

Step 4. Repeat Step 3 if the rate of
continued ow out of the drain was
noticeably reduced.

Step 5. Determine whether the water is
owing from the Alarm Port (Ref. Figure

1) or past the Alarm Test Valve. If the
leakage is past the Alarm Test Valve,
close the main control valve, and then
repair or replace the Alarm Test Valve
as necessary.

Step 6. If it appears that the leakage
noted in Step 5 is from the Alarm Port,
drain the system in accordance with
the prescribed procedure. After the
system has been drained, remove the
Handhole Cover.

Step 7. While holding the Spring down
by the coils, remove the Hinge Pin.
Remove the Spring and Waterway
Clapper Assembly.

TFP910

Page 18 of 20

Step 8. Using a light, check for and

remove any debris that may have
become lodged within the Seat Ring
groove. Inspect the Seat Ring seat
for any damage. If the Seat Ring has
become dented across the seat then
the Alarm Check Valve will have to be
replaced. It is impractical to re-face a
Seat Ring in the eld.

Step 9. Check for and remove any
debris that may have become lodged
in the Clapper Facing. If a minor imper­fection remains in the Clapper Facing,
then turn it over after thoroughly clean­ing both surfaces with a clean cloth.
Replace the Clapper Facing if neces­sary. Be sure to securely re-tighten
the retaining fastener for the Clapper
Washer.

Step 10. Replace the Spring and
Waterway Clapper Assembly as shown
in Figure 1. While holding the coils of
the Spring down, re-insert the Hinge
Pin. Be sure that the Hinge Pin is
pushed all the way to the rear of the
valve.

Step 11. Replace the Handhole Cover.
Return the Alarm Valve to operation in
accordance with the steps described in
the Setting Procedure section.

Clogged Alarm Line Drain

If water either does not ow or only
dribbles out of the alarm line drain dur­ing an alarm test, then it is likely that
the screen protecting the Restriction
Assembly drain orice (Ref. Figure 3)
has become clogged.

NOTICE

For variable pressure systems, a
clogged alarm line drain will increase
the likelihood of a false alarm.

First break the union downstream of
the Drain Restriction and remove the
Drain Restriction for cleaning by back­ushing the screen. Re-install the Drain
Restriction and re-assemble the drain
line.

Loss of Excess System Pressure

For variable pressure systems, the
System Pressure Gauge normally indi­cates a pressure greater than that
shown by the Supply Pressure Gauge.
Also, the value should be close to that
of the peak supply pressure that has
occurred after the system was placed
in service.

NOTICE

For variable pressure systems, loss of
excess system pressure will increase
the likelihood of a false alarm.

Follow the procedure indicated below
to correct a loss of excess system
pressure condition.

Step 1. Check for signs of continued
leakage from the alarm line drain. If rust
stains and/or water deposits indicate
that continued leakage has been taking
place, take corrective action according
to the procedure described in the sub­section entitled “Leakage from Alarm
Line Drain.”

Step 2. If there are no signs of contin­ued leakage from the alarm line drain,
close the main control valve, slowly
remove the plug from the supply pres­sure gauge test valve to relieve the
supply pressure, and then slowly open
the union in the externally mounted
bypass.

Step 3. Check for leakage past the
Bypass Check Valve. If there is leak­age, debris may have become lodged
between its clapper and seat. Drain
the system in accordance with the
prescribed procedure and then clean
or replace the Bypass Check Valve as
required.

Step 4. Re-assemble the externally
mounted bypass, replace the plug into
the Gauge Test Valve, and return the
re protection system to operation in
accordance with the steps described
in the Operation section.

Step 5. If there are no signs of leak­age past either the Alarm Check Valve
Clapper per Step 1 or the Bypass
Check Valve per Step 2, inspect the
sprinkler system for leakage.

Excess Pressure Due to
Thermal Expansion

Wet pipe sprinkler systems subject
to ambient temperatures in excess of
100°F (38°C) can experience signicant
increases in system pressure due to
the thermal expansion of the water. In
particular, a gridded wet-pipe system
with a relatively small air pocket and
no relief valve can be subjected to an
increase of more than 100 psi (6,9 bar),
due to an increase in ambient tempera­ture of approximately 50°F (28°C).

As necessary, install a pressure
relief valve, in accordance with the
requirements of the authority having
jurisdiction, to automatically relieve
the excess pressure that could other­wise be created in wet-pipe systems
exposed to signicant increases in
ambient temperature.

False Alarms

Follow the step below when repeated
false alarms occur in a variable pres­sure system.

Step 1. Check for and correct the
cause of continued leakage out the
alarm line drain.

Step 2. Check for and clean a clogged
alarm line drain.

Step 3. Check for and correct the
cause of a loss in excess system
pressure.

Step 4. Drain the sprinkler system and
re-ll it using the steps described in the
Setting Procedure section.

Intermittent Alarms

If the pressure alarm switch gives a
steady signal, but the water motor gen­erates an intermittent alarm, check for
binding in the water motor alarm drive
shaft.

If the water motor alarm and/or the
pressure alarm switch provide an
intermittent alarm, it is likely the conse
quence of an excessive amount of air
being trapped within the sprinkler sys­tem. Drain down the sprinkler system
and rell it using the steps described in
the Setting Procedure section.

A discontinuance of an alarm may also
be caused by the Clapper closing due
to a sudden drop in supply pressure
or the shut-off of a pump in the supply
line. These types of problems can only
be corrected by maintaining a steady
supply pressure.
