-TYPICAL ARRANGEMENT-
The 1 inch (25mm) Model F540 Resi-
dential Domestic Shutoff Valve (Ref.
Figure A) is intended for use in dual-
purpose residential supply piping that
serves both domestic and NFPA 13D
residential fire protection sprinkler sys-
tem needs. When an automatic fire
sprinkler operates, the F540 Valve au-
tomatically shuts off essentially all
water flow to the domestic system and
diverts the available water supply to
the fire sprinkler system.
Surveys have indicated that residen-
tial domestic water usage can be ex-
pected to vary from 5 GPM (18,9 LPM)
to 20 GPM (75,7 LPM), all depending
on the city main pressure, the design
of the piping system, and the number
of water outlets. These levels of water
usage could impair the performance of
a residential fire sprinkler system, if
they resulted in a significant reduction
in the anticipated water supply pres-
sure to the fire sprinkler system.
Printed in U.S.A. 9-93
Therefore, it is recommended that the
design of a residential fire sprinkler
system take into account the antici-
pated domestic water usage, unless
provision is made to shutoff essentially
all water flow into the domestic sys-
tem, upon operation of a fire sprinkler.
At a typical residual (flowing) pressure
of 40 psi (2,8 bar) at the inlet to the
F540 Valve, following operation of a
fire sprinkler, the flow into the domestic
system would automatically be re-
duced to less than l/4 GPM (0,9 LPM).
Use of the Model F540 Residential Do-
mestic Shutoff Valve should be consid-
ered when either the water supply can-
not adequately provide for both the
possible domestic usage and fire
sprinkler flow demand, or it is desirable
to increase the effectiveness of the fire
sprinkler system by automatically
shutting off essentially all domestic
flow.
The F540 maximizes the effective use
of an existing water supply and, there-
fore, in areas with limited water sup-
plies, it may eliminate the need to add
costly pumps, pressurized reservoirs,
or electrically operated domestic shut-
off valves. The F540 has a built-in
check valve in the fire sprinkler system
outlet, which eliminates the need for a
separate check valve. Also, the F540
automatically resets, thereby eliminat-
ing the need for valve disassembly
after a fire sprinkler system test or op-
eration.
The Model F540 Residential Domestic
Shutoff Valve is listed by Underwriters
Laboratories Inc. and is suitable for
use in water supply arrangements for
residential fire sprinkler systems de-
signed per NFPA 13D.

-ASSEMBLY AND DIMENSIONS-
In order for the F540 Valve to automat-
ically operate, once a fire sprinkler op-
erates, the fire sprinkler system from
the water main to the most hydrauli-
cally remote sprinkler must be de-
signed to provide a minimum single
sprinkler flow of 12.5 GPM (47,3 LPM),
when the supply pressure at the main
is at its minimum expected value.
NOTES
The minimum single sprinkler flow
rate of 12.5 GPM (47,3 LPM), re-
quired for use with the F540 Valve,
does not take precedence over any
more hydraulically demanding single
or multiple sprinkler flow rates speci-
fied for the residential sprinklers
being utilized.
It is not necessary to take into account
the trickle flow through the F540
Valve By-Pass Restriction, into the do-
mestic system, when performing hy-
draulic design calculations for the fire
sprinkler system.
-2-
The design of the F540 Valve is such
that if there is a fire sprinkler operation
while there is domestic usage, the
F540 Valve will automatically shut off
essentially all flow to the domestic sys-
tem and divert the available water sup-
ply to the fire sprinkler system, thereby
eliminating the lower sprinkler flow that
might otherwise be caused by a signif-
icant domestic water usage.
When the F540 Valve is in the normal
standby position as shown in Figure D,
the Poppet Assembly, assisted by the
Spring, is in the down position. With
the Poppet Assembly in the down po-
sition, the Fire Sprinkler Seat is sealed
and the F540 Valve performs as a con-
vential check valve. Also, with the Pop-
pet Assembly in the down position,
water is available on demand through
the Domestic Flow Passage and out
the Domestic Port.
When operation of the automatic resi-
dential fire sprinkler system results in
a water demand, the Poppet Assembly
OBSOLETE

moves upward. With the Poppet As-
sembly in the full up position, water
flow is diverted from the Domestic
Flow Passage to the Fire Sprinkler
Flow Passage. After the Poppet As-
sembly has moved to the full up posi-
tion, only a small amount of water is
permitted to trickle through the By-
Pass Restriction to the Domestic Port.
The trickle flow through the By-Pass
Restriction permits automatic resetting
of the F540 Valve, without draining of
the fire sprinkler system, after a sprink-
ler operation or test. When the Manual
Domestic Shutoff Valve is closed, the
By-Pass Restriction allows the Supply
and Domestic Port pressures to equal-
ize and the Poppet Assembly to move
back down to the standby position. The
maximum flow rate through the By-
Pass Restriction, when the F540 Valve
is in the operated position is less than
l/4 GPM (0,9 LPM) for a typical resid-
ual (flowing) pressure of 40 psi (2,8
bar) at the inlet. Consequently, it is not
necessary to take into account the
trickle flow through the F540 Valve By-
Pass Restriction, into the domestic
system, when performing hydraulic de-
sign calculations for the fire sprinkler
system.
The contours of the Poppet Assembly
have been specifically configured to
minimize its upward movement except
under the level of sustained fire sprink-
ler system flow resulting from opera-
tion of a fire sprinkler. However, be-
cause most fire sprinkler systems
contain air pockets, the Poppet As-
sembly will tend to move momentarily
upward if there is a surge in supply
pressure. The momentary opening
and reclosing of the Poppet Assembly
at the Fire Sprinkler Seat will trap a
portion of the pressure increase within
the fire sprinkler system. The trapping
of pressure increases within the fire
sprinkler system will help to reduce the
possibility of a subsequent surge in the
supply pressure from causing the
waterflow detector to signal a false
alarm.
As indicated above, domestic system
usage may reduce the pressure avail-
able to the fire sprinkler system. How-
ever, when utilizing the F540 Valve, it
is not necessary to take into account
the complex hydraulic modeling of the
domestic system, that would otherwise
be required to determine the minimum
possible residual (flowing) pressure
which would be available to the fire
sprinkler system.
For operation of the F540 Valve, it is
only necessary to design the fire
sprinkler system, from the water main
to the most hydraulicaly remote sprink-
ler, to provide a minimum single sprink-
ler flow of 12.5 GPM (47,3 LPM), when
the supply pressure at the main is at its
minimum expected value.

ularly scheduled maintenance. How-
ever, proper operation of the F540
Valve should be verified at least annu-
ally. Any impairment must be im-
mediately corrected.
It is also recommended that fire protec-
tion systems be inspected by a quali-
fied Inspection Service.
NOTES
No attempt is to be made to repair any
F540 Valve component in the field.
The operational test procedure will
result in operation of the associated
alarms. Consequently, notification
must begiven to the owner and the fire
department, central station, or other
signal station to which the ala.rms are
connected.
Before closing a fire protection system
main control valve for maintenance
worfz on the fire protection system
which it controls, advise all occupants
of the residence that the fire protection
system is being disabled.
Operation Test Procedure
1. Fully open any two water outlets in
the domestic piping system.
2. Open the Drain and Test Connection
of the fire sprinkler system, to simu-
late a sprinkler operation.
3. Verify that the alarms are operating
and that the flow from both of’the
domestic water outlets has de-
creased to a trickle.
4. While water is flowing, record the
pressure reading on the fire sprinkler
system pressure gauge and then
compare this reading to previous
readings. If there is a significant de-
crease in pressure, which is not due
to a normally expected drop in the
water supply pressure, there may be
an impairment which should be im-
mediately identified and corrected.
5. Reset the F.540 Valve in accordance
with the Valve Setting Procedure.
NOTE
After returning a fire protection sys-
tem to service, notify the proper au-
thorities and advise those responsible
for monitoring proprietary and /or
central station alarms.
