The absence of air discharging from

the Automatic Drain Valve is an indica-

tion of a properly set air seat within the

DPV-1 Valve. If air is discharging, refer

to the Care and Maintenance section

under Automatic Drain Valve Inspection

to determine/correct the cause of the

leakage problem.

Step 10.

Partially open the Main

Control Valve. Slowly close the Main

Drain Valve as soon as water dis-

charges from the drain connection.
Depress the plunger on the Automatic

Drain Valve to make sure that it is open

and that there is no water discharging.

The absence of water discharging from

the Automatic Drain Valve is an indica-

tion of a properly set water seat within

the DPV-1 Valve. If water is discharg-

ing, refer to the Care and Maintenance

section under the Automatic Drain

Valve Inspection to determine/correct

the cause of the leakage problem.
If there are no leaks, the DPV-1 Valve is

ready to be placed in service and the

Main Control Valve must then be fully

opened.

Note:

After setting a fire protection

system, notify the proper authorities

and advise those responsible for moni-

toring proprietary and/or central station

alarms.

Step 11.

Once a week after a valve is

reset following an operational test or

system operation, the Low Body Drain

Valve (and any low point drain valves)

should be partially opened (and then

subsequently closed) to relieve drain-

back water. Continue this procedure

until drain-back water is no longer

present.

Care and

Maintenance

The following procedures and inspec-

tions should be performed as indicated,

in addition to any specific requirements

of the NFPA, and any impairment must

be immediately corrected.
Before closing a fire protection system

main control valve for maintenance

work on the fire protection system that

it controls, permission to shut down the

affected fire protection system must be

obtained from the proper authorities

and notify all personnel who may be

affected by action.
The owner is responsible for the

inspection, testing, and maintenance of

their fire protection system and devices

in compliance with this document, as

well as with the applicable standards

of the National Fire Protection Associa-

tion (e.g., NFPA 25), in addition to the

standards of any authority having juris-

diction. Contact the installing contrac-

tor or sprinkler manufacturer regarding

any questions.
Automatic sprinkler systems are rec-

ommended to be inspected, tested,

and maintained by a qualified Inspec-

tion Service in accordance with local

requirements and/or national codes.
The operational test procedure and

waterflow pressure alarm test pro-

cedure will result in operation of the

associated alarms. Consequently,

notification must first be given to the

owner and the fire department, central

station, or other signal station to which

the alarms are connected.

Annual Operation Test Procedure

Note:

Unless otherwise noted, refer to

Figure 4, 5, or 6 to identify functional

trim components.

Proper operation of the DPV-1 Valve

(i.e., opening of the DPV-1 Valve during

a fire condition) should be verified at

least once a year as follows:

Step 1.

If water must be prevented

from flowing beyond the riser, perform

the following steps.
•   Close the Main Control Valve.
•   Open the Main Drain Valve.
•   Open the Main Control Valve one

turn beyond the position at which

water just begins to flow from the

Main Drain Valve.

• Close the Main Drain Valve.

Step 2.

Open the system’s Inspector’s

Test Connection.

Step 3.

Verify that the DPV-1 Valve

has operated, as indicated by the flow

of water into the system and that all

waterflow alarms operate properly.

Step 4.

Close the system’s Main

Control Valve.

Step 5.

Reset the DPV-1 Valve in

accordance with the Valve Setting

Procedure.

Note:

It is recommended that the

requirement of NFPA 25 to annually

inspect the inside of the valve be per-

formed at this time and prior to reset-

ting the DPV-1 Valve. Refer to the

Automatic Drain Valve Inspection sub-

section Steps 2 through 5 for instruc-

tions with regard to the inspection of

the Clapper Facing.

Quarterly Waterflow

Alarm Test Procedure

Testing of the system waterflow alarms

should be performed quarterly. To test

the waterflow alarm, open the Alarm

Test Valve, which will allow a flow of

water to the Waterflow Pressure Alarm

Switch and/or Water Motor Alarm.

Upon satisfactory completion of the

test, close the Alarm Test Valve.

Water Pressure Inspection

The Water Pressure Gauge is to be

inspected monthly (per NFPA 25) to

ensure that normal system water pres-

sure is being maintained.

Air Pressure Inspection

The Air Pressure Gauge is to be

inspected monthly (per NFPA 25) to

ensure that normal system air pressure

is being maintained.

Automatic Drain Valve Inspection

The Automatic Drain Valve should be

inspected monthly (per NFPA 25) by

depressing the plunger and check-

ing to ensure that the Automatic Drain

Valve is not discharging water and/or

air. A discharge of water and/or air is

an indication that the air and/or water

seats are leaking, which could subse-

quently cause a false operation should

the intermediate chamber become

inadvertently pressurized.
If leakage is present, take the DPV-1

Valve out of service (i.e., close the

main control valve, open the main drain

valve, close the air supply control valve,

remove the Dry Pipe Valve Accelerator

from service, as applicable, in accor-

dance with its Technical Data Sheet

(Refer to TFP1105 for the VIZOR or

TFP1112 for the ACC-1), and open the

Inspector’s Test Connection to relieve

the system air pressure to 0 psig as

indicated on the System Air Pressure

Gauge), and then after removing the

Handhole Cover, perform the follow-

ing steps:

Step 1.

Make sure that the Seat Ring

is clean and free of any nicks or signifi-

cant scratches.

Step 2.

Remove the Clapper Assem-

bly from the valve by first pulling out

the Hinge Pin.

Step 3.

Disassemble the Clapper

Facing Retainer from the Clapper

so that the Clapper Facing can be

removed and inspected. Make sure

that the Clapper Facing does not show

signs of compression set, damage, etc.

Replace the Clapper Facing if there is

any signs of wear.

Step 4.

Clean the Clapper Facing,

Clapper, and Clapper Facing Retainer,

and then reassemble the Clapper

Assembly.

Step 5.

Reinstall the Clapper Assembly

with its Hinge Pin and then reinstall the

Handhole Cover.
