Valve Setting
Procedure
Steps 1 through 9 are to be performed
when initially filling the fire sprinkler
and domestic system piping with water
or after a fire sprinkler operation (Ref.
Figure 1).
Step 1. Close the Main Control Valve.
Step 2. Close the Domestic Control
Valve, and all water outlets in the do-
mestic piping system.
Step 3. Close all drain valves in addi-
tion to the Drain and Flow Test Con-
nection in the fire sprinkler system,
and replace all operated sprinklers as
necessary.
Step 4. Partially open the Main Control
Valve until the sound of flowing water
just begins, and then leave the Main
Control Valve in the partially open po-
sition.
Step 5. After the fire sprinkler system
pressure gauge indicates approxi-
mately the same pressure as the sup-
ply pressure gauge, fully open the
Main Control Valve.
Step 6. Open the highest elevation
outlet on the domestic system.
Step 7. Partially open the Domestic
Control Valve until the sound of flowing
water begins. Allow the domestic pip-
ing to slowly fill with water.
Step 8. Close the highest elevation
water outlet on the domestic system
when unaerated water begins to flow.
Step 9. Completely open the Domestic
Control Valve, and then check that the
domestic system is properly pressur-
ized by verifying that at least three
water outlets in the domestic system
can flow full at the same time.
If the water outlets flow full, the RSV-1
Valve is set and ready for service and
the water outlets on the domestic sys-
tem may be closed.
If the water outlets do not flow full,
reclose the Domestic Control Valve,
wait a minimum of ten seconds, and
ensure that there is no flow from the
fire sprinkler system piping. Reopen
the Domestic Control Valve and then
recheck that the water outlets are flow-
ing full.
Care and
Maintenance
The following inspection procedure
must be performed as indicated, in ad-
dition to any specific requirements of
the NFPA, and any impairment must
be immediately corrected.
The owner is responsible for the in-
spection, testing, and maintenance of
their fire protection system and de-
vices in compliance with this docu-
ment, as well as with the applicable
standards of the National Fire Protec-
tion Association (e.g., NFPA 25), in
addition to the standards of any
authority having jurisdiction. The in-
stalling contractor or product manufac-
turer should be contacted relative to
any questions.
It is recommended that automatic
sprinkler systems be inspected,
tested, and maintained by a qualified
Inspection Service in accordance with
local requirements and/or national
codes.
NOTES
Noattemptistobemadetorepairany
RSV-1 valve component in the field.
The operational test and flow test pro-
cedures will result in operation of the
associated alarms, as well as an inter-
ruption of the domestic water supply
service. Consequently, notification
must be given to the owner and the fire
department, central station, or other
signal station to which the alarms are
connected, and notification must be
given to the building occupants.
Before closing a fire protection system
control valve for inspection or mainte-
nance work on the fire protection sys-
tem that it controls, permission to shut
down the effected fire protection sys-
tem must first be obtained from the
proper authorities and all personnel
who may be affected by this action
must be notified.
After placing a fire protection system
in service, notify the proper authorities
and advise those responsible for moni-
toring proprietary and/or central sta-
tion alarms.
Operation Test Procedure
Step 1. Fully open two or three water
outlets in the domestic piping system.
Step 2. Open the Alarm Test Connec-
tion of the fire sprinkler system, to
simulate a sprinkler operation.
Step 3. Verify that the alarms are op-
erating and that the flow from the do-
mestic water outlets has decreased to
no more than a trickle.
Step 4. Reset the RSV-1 Valve in ac-
cordance with the Valve Setting Proce-
dure.
Flow Test Procedure
Step 1. While there is no water flowing
in the domestic system, completely
open the Drain and Flow Test Connec-
tion.
Step 2. While water is flowing, record
the pressure reading on the fire sprin-
kler system pressure gauge and then
compare this reading to previous read-
ings. If there is a significant decrease
in pressure since the last time the
pressure reading was taken which is
not due to a normally expected drop in
the water supply pressure, there may
be an impairment that should be imme-
diately identified and corrected.
Step 3. Close the Drain and Flow Test
Connection to allow the RSV-1 Valve
to automatically reset. Automatic re-
setting will occur within ten seconds.
Step 4. After waiting ten seconds,
completely open at least three water
outlets in the domestic system and al-
low them to simultaneously flow.
If the water outlets flow full, the RSV-1
Valve is set and ready for service and
the water outlets on the domestic sys-
tem may be closed.
If the water outlets do not flow full,
close the Domestic Control Valve and
verify that there is no flow from the fire
sprinkler system piping (such as at the
Inspector’s Test Connection). Wait a
minimum of ten seconds. Reopen the
Domestic Control Valve and then re-
check that the domestic system water
outlets are flowing full.
