5.  Open the factory-installed manual pull station that is as-

sembled to the exterior of the PrePaK’s 24VDC Terminal 
Box.   This will energize the solenoid valve open.  Doing 
so will result in a sudden drop of water pressure in the 
deluge valve’s push rod chamber. 

6.  Reset the system per the directions listed in “System 

Setup” section of this bulletin.

Draining Excess/Condensate Water From System 

Refer to Figs. 10, 11 or 12 (depending on system size) 
1.  Close the main valve controlling water supply to deluge 

valve. Also close valve A and open main drain valve B. 

2.  Open condensate drain valve H until all water has 

drained. Close valve H. 

Note:

 Be sure not to keep valve 

H open for an extended period of time because that will 
cause enough system air to bleed off thereby actuating 
the Model LP Dry Valve Actuator (see Table A for pneu-
matic pressure values required to maintain the Model 
LP Dry Valve Actuator closed for a given water supply 
pressure). If the Actuator does happen to actuate, the 
entire system must be re-established in the correct or-
der as to avoid any possibilities of false-tripping of the 
deluge valve. Proceed according to the directions listed 
in the “System Setup” section of this bulletin. 

3.  Close main drain valve B. If system contains pressur-

ized air, allow air pressure to come back up to specifica-
tion. Open valve A first, and then open the main valve 
controlling the water supply to the deluge valve.

SOLENOID VALVE INSPECTIONS, TESTS 
AND MAINTENANCE

WARNING: THE OWNER IS RESPONSIBLE FOR MAIN-
TAINING THE FIRE PROTECTION SYSTEM IN PROP-
ER OPERATING CONDITION. ANY SYSTEM MAINTE-
NANCE OR TESTING THAT INVOLVES PLACING A 
CONTROL VALVE OR DETECTION SYSTEM OUT OF 
SERVICE MAY ELIMINATE THE FIRE PROTECTION 
OF THAT SYSTEM. PRIOR TO PROCEEDING, NOTIFY 
ALL AUTHORITIES HAVING JURISDICTION. CONSID-
ERATION SHOULD BE GIVEN TO EMPLOYMENT OF 
A FIRE PATROL IN THE AFFECTED AREA. 

WARNING: PRIOR TO OPERATING THE SOLENOID 
VALVE, BE SURE TO CLOSE THE SYSTEM CONTROL 
VALVE TO AVOID UNINTENTIONAL OPERATION OF 
THE DELUGE VALVE

1.  Inspections: It is imperative that the system be in-

spected and tested in accordance with NFPA 25 on 
a regular basis. The frequency of the inspections 
may vary due to contaminated water supplies, cor-
rosive water supplies, or corrosive atmospheres. In 
addition, the alarm devices, detection systems, or 
other connected trim may require a more frequent 
schedule. Refer to the system description and ap-
plicable codes for minimum requirements.

2.  The valve must be inspected at least monthly for 

cracks, corrosion, leakage, etc., cleaned and re-
placed as necessary.

3.  If leakage is suspected through the solenoid valve, it 

should be replaced.
