6. INsPECTIoN AND oPErATIoNAL TEsT
NoTICE: THE owNEr Is rEsPoNsIBLE For MAINTAINING THE FIrE ProTECTIoN sysTEM AND DEVICEs IN ProPEr
oPErATING CoNDITIoN.
It is im�erative that the system is ins�ected and tested on a regular basis in accordance with NFPA 25.
The �requency o� the ins�ections may vary due to contaminated water su��lies, corrosive water su��lies, corrosive atmos�heres, as
well as the condition o� the air su��ly to the system. For minimum maintenance and ins�ection requirements, re�er to NFPA 25. In ad-
dition, the Authority Having Jurisdiction may have additional maintenance, testing, and ins�ection requirements that must be �ollowed.
�iking does not require internal ins�ection o� the valve as �art o� routine ins�ection and testing. Internal maintenance is generally only
required �or valve re�airs and internal com�onent re�lacement.
wArNING:
Any system maintenance that involves �lacing a control valve or detection system out o� service may eliminate the �ire
�rotection ca�abilities o� that system. Prior to �roceeding, noti�y all Authorities Having Jurisdiction. Consideration should be given to
em�loyment o� a �ire �atrol in the a��ected areas.
A. Low Air Pressure Alarm Test:
(Re�er to Figure 5.)
Quarterly testing o� low air alarms is recommended.
To Test S�rinkler System “Low Air Su�ervisory” Alarm:
1. To �revent o�eration o� the G-4000P �alve and �illing the system with water during the test, DO NOT o�erate the electric
detection system during the test. Consider closing the main water su��ly control valve.
2. Partially o�en the s�rinkler system main drain or test connection.
3. �eri�y that low air alarms o�erate within an acce�table time �eriod and continue without interru�tion.
4. Close the main drain or test connection.
5. Establish the su�ervisory air �ressure to the recommended �ressure.
6. Reset the system release control �anel. The su�ervisory alarms should sto�.
when testing is complete, return the system to service following steps 1 through 8 below.
B. Full Flow Trip Test: (refer to Figure 5.)
Per�ormance o� a tri� test is recommended annually during warm weather. Consider coordinating this test with o�eration testing
o� the detectors.

To Tri� Test the Electrically Controlled Preaction System:
1. Noti�y the Authority Having Jurisdiction and those in the area a��ected by the test.
2. Tri� the G-4000P �alve by �er�orming o�tion “a” or “b” below.
O�erate the electric release control system according to the manu�acturer’s instructions (�or the Single Interlock or
Double Interlock System) and o�en the s�rinkler system test connection (�or Double Interlock Systems).
and o�en the s�rinkler system test connection (�or Double Interlock Systems)..
O�erate the emergency release valve.
3. The G-4000P �alve should o�en, �illing the s�rinkler system with water. Water �low alarms should o�erate.
4. O�en the s�rinkler system main drain valve or s�rinkler system test valve to veri�y adequate �low.
when Trip Testing is complete:
5. Per�orm ste�s 1 through 16 o� section 4.F - PLACING THE SYSTEM IN SER�ICE to return the system to service.
6. Noti�y the Authority Having Jurisdiction and those in the a��ected area that testing is com�lete.
7. MAINTENANCE
�iking does not require an internal ins�ection o� the G-4000P �alve unless there is an indication o� damage to internal com�onents.
A. Taking the system out of service:
(Re�er to Figure 5.)
1. Close the water su��ly main control valve, �lacing the system out o� service.
2. O�en the �low test valve located in the base o� the G-4000P �alve.
3. Close the air (or nitrogen) su��ly to the �reaction system �i�ing.
4. Close the �riming valve.
5. Relieve all air �ressure �rom the �reaction system �i�ing. I� the system has o�erated, o�en the main drain valve to allow the
system to drain com�letely.
B. removing the Cover from the Body:
(Re�er to Figures 1 & 11.)
1. Remove the 4” cou�ling �rom the to� o� the G-4000P �alve.
2. Remove the 12” section o� �i�e directly above the G-4000P �alve.

3. Remove the air su��ly line �rom the air su�ervisory switch.
4. Remove the 2” cou�ling below the main drain.
5. Remove the 12 cover screws (12).
