Instructions
General
Description
The appendix found at the end of this
document provides valve setting and
testing/inspection procedures summa-
rized from the Care and Maintenance
section.
Some jurisdictions require a copy of the
Summary Instructions appendix to be
displayed in proximity to a DV-5
A
Auto-
matic Control Valve riser supplying a
fire protection system.
Reproduce as an individual poster by
printing on appropriate media.
A form of protection is recommended
to prevent damage which could render
the poster illegible. Conditions to avoid
include moisture infiltration, fading,
mutilation, etc.. Protective measures
may include lamination, placement
within an impact- and water-resistant
frame, etc.
The format shown in this document is
landscape orientation on US Tabloid
size, also known as ANSI B drawing
format, both roughly comparable to
ISO A3 size format.
To avoid potential cropping of content
when printing to A3 format, select
options such as print to fit or scale
to fit. Depending on printer capabil-
ity content will be slightly reduced but
should remain readable.
See Print Format Dimensions Table for
details.

NOTICE
The procedures provided are summary instructions of the complete procedures appearing in
Technical Data Sheet TFP1485. If problems occur, consult full document.
Valve Setting Procedure
1.
Close System Main Control Valve (B), Diaphragm Supply Valve (P), and Air Supply Control
Valves (X) and (Y).
2.
Open Main Drain Valve (D), System Drain Valve (E), and all auxiliary drains in system. Also,
remove plug from Air Supply Strainer (W) to drain any water and ensure it is clean and free
of debris. Close auxiliary drain valves, System Drain Valve (E), and reassemble Air Supply
Strainer (W) after water stops discharging. Leave Main Drain Valve (D) open.
3.
Ensure Pressure Gauge Valves and Alarm Control Valve (H), as applicable, are open.
4.
Depress plunger of Automatic Drain Valve (F) to verify it is open.
5.
Clean Diaphragm Supply Strainer (Q). Flush strainer by opening the Diaphragm Supply
Valve (P).
6.
Replace operated automatic sprinklers on system piping.
7.
Reset DV-5
A
Valve Releasing Panel in accordance with manufacturer instructions.
8.
Re-establish system air pressure to reset Model DP-1 Dry Pilot Actuator (T) by opening Air
Supply Control Valve (X). Do not open Air Supply Control Valve (Y) at this time. Observe Dry
Pilot Actuator (T) air pressure on Dry Pilot Gauge (Z).
9.
Open Manual Control Station (M), then open Diaphragm Supply Valve (P). After aerated
water stops discharging from Manual Control Station (M) drain tube, slowly close operating
lever. Do not close hinged cover at this time.
10.
After aerated water stops discharging, reset Manual Reset Actuator (N) until water stops
flowing from its drain tube and pressure reaches approximately 15 psi (1,0 bar) on Diaphragm
Gauge (K).
11.
With diaphragm chamber pressurized, temporarily close Diaphragm Supply Valve (P), and
observe Diaphragm Gauge (K) for a drop in pressure. If pressure drop is noted, replace DV-5
A
Diaphragm and correct any leaks before proceeding.
12.
If Diaphragm Gauge (K) indicates no drop in pressure, re-open Diaphragm Supply Valve
(P) and proceed.
13.
Open Air Supply Control Valve (Y) to pressurize system piping.
14.
Partially open System Main Control Valve (B). Slowly close Main Drain Valve (D) as water
discharges from Main Drain Valve (D). Observe Automatic Drain Valve (F) for leaks. If there
are leaks, correct the leakage problem.
15.
Close hinged cover of Manual Control Station (M) and insert new break rod in small hole
through the top of the enclosing box.
16.
Open System Main Control Valve (B).
17.
After setting fire protection system, notify proper authorities and advise those responsible
for monitoring proprietary and/or central station alarms.
Waterflow Alarm Test Procedure
1.
Open Alarm Test Valve (G), allowing water to flow to Waterflow Pressure Switch (C) and/or
Water Motor Alarm. Close Alarm Test Valve (G) when test is completed.
2.
Depress plunger on the Automatic Drain Valve (F) to drain alarm line.
Solenoid Valve Test Procedure For Electric Actuation
1.
Close System Main Control Valve (B) and open Main Drain Valve (D).
2.
Test deluge releasing panel in accordance with manufacturer’s instructions to energize
the Solenoid Valve (R).
3.
Verify that water is flowing from Solenoid Valve (R) drain connection.
4.
Verify Diaphragm Chamber pressure has decreased to below 25% of water supply pressure.
5.
Reset electric detection system in accordance with manufacturer’s instructions to de-ener-
gize Solenoid Valve (R). Water should top draining from Solenoid Valve (R) but remain draining
from Manual Reset Actuator (N).
6.
Press Reset Knob on Manual Reset Actuator (N) and hold a few seconds until water stops
flowing.
7.
After system pressure is restored, inspect Solenoid Valve (R) and Manual Reset Actuator
(N) for leaks. Correct any leaks before proceeding.
8.
Partially open System Main Control Valve (B). Slowly close Main Drain Valve (D) as water
discharges from Main Drain Valve (D). Observe Automatic Drain Valve (F) for leaks. If there
are leaks, correct the leakage problem. If there are no leaks, place DV-5
A
Valve in service and
open System Main Control Valve (B).
Solenoid Valve and Dry Pilot Actuator Test Procedure
1.
Close System Main Control Valve (B) and open Main Drain Valve (D).
2.
Simulate power failure by disconnecting main power to releasing panel, and disconnecting
battery back-up. Refer to releasing panel manufacturer’s instructions for specific details. This
step allows Solenoid Valve (S) to open.
3.
Open system’s Inspector’s Test Connection to relieve system air pressure.
4.
Verify water flow from Dry Pilot Actuator (T) drain connection.
5.
Verify Diaphragm Chamber pressure decreased to below 25% of water supply pressure.
6.
Close Inspector’s Test Connection and allow the system air pressure to re-establish. Water
stops draining from Dry Pilot Actuator (T) but continues to drain from Manual Reset Actua-
tor (N). Press Reset Knob on Manual Reset Actuator (N) and hold a few seconds until water
stops flowing from drain tube.
7.
Pressure will then build up in DV-5
A
Diaphragm Chamber.
8.
After system pressure is restored, inspect Solenoid Valve (R) and Manual Reset Actuator
(N) for leaks. Any leaks must be corrected before proceeding.
9.
Reestablish battery and main power to releasing panel in accordance with manufacturer’s
instructions.
10.
Partially open System Main Control Valve (B). Slowly close Main Drain Valve (D) as water
discharges from Main Drain Valve (D), then close Main Drain Valve (D). Observe Automatic
Drain Valve (F) for leaks and correct the leakage problem. If there are no leaks, place DV-5
A
Valve in service and open System Main Control Valve (B).
Supervisory Low Pressure Alarm Test Procedure and Validation of Normally Closed
Solenoid Valve (S)
1.
Close System Main Control Valve (B), and open Main Drain Valve (D).

Verify Supervisory Low Pressure Alarm Switch (V) is operational and low pressure set point
is approximately 0,4 bar under minimum system air pressure.
3.
Allow system air pressure to decay to 0 psig. Verify no water draining from Dry Pilot Actu-
ator (T).
4.
Close system’s Inspector’s Test Connection and allow system supervisory pressure to auto-
matically re-established. As necessary, open, then close quick fill air supply control valve in
automatic air maintenance device. Supervisory Low Pressure Alarm Switch (V) should return

discharges from Main Drain Valve (D). Observe Automatic Drain Valve (F) for leaks. If there
are leaks, correct the leakage problem. If there are no leaks, place DV-5
A
Valve in service and
open System Main Control Valve (B).
Operation Test Procedure
1.
To prevent water from flowing beyond riser, close System Main Control Valve (B). Open
Main Drain Valve(D).
