B. Verify that the system has been properly drained. (When plunger is depressed on drip check, (B.7) no water should flow.) System
Drain (G.4) should be closed. Verify that Emergency Release (B.11) is closed.
C. Verify that the System Main Water Supply Control Valve (D.1) is closed and the Deluge Valve (A.1) is trimmed according to current
Viking Trim Technical data page for the system used (See section 12).
D. Verify that the system water supply piping is pressurized up to the closed System Main Water Supply Control Valve (D.1) and the
priming line is pressurized up to the closed Priming Valve (B.1).
E. Restore system water pressure by opening the Bypass Isolation Valve (G.3). Make sure supervisory switch (E.1) is set to proper
activation pressure per Table 1.
F. Open Priming Valve (B.1) and system Maintenance Valve (F.3). When the system is full of water, close the system Bypass Isolation
Valve (G.3).
G. Reset the PAR-3 Control Panel (F.8): Open panel and press “RESET”. Release Solenoid Valve (F.2) should close. Flow from
Release Solenoid Valve (F.2) to Drain Cup (B.14) should stop.
H. Open Flow Test Valve (B.15).
I. Partially open Main Water Supply Control Valve (D.1) (If closed).
J. When full flow develops from Flow Test Valve (B.15), close the Flow Test Valve.Verify that there is no flow from open Auxiliary Drain
(B.6).
K. Close Auxiliary Drain (B.6) and Bypass Valve (G.3).
L. Fully open and secure the Main Water Supply Control Valve. (D.1)
M. Verify that the Alarm Shut-off Valve (B.9) is open and that all other valves are in their normal operating position.
N. Depress the plunger of Drip check (B.7). No water should flow from the Drip Check when the plunger is pushed.
10. EMERGENCY INSTRUCTIONS
(Refer to Figure 1)
Taking System Out of Service:
WARNING: PLACING A CONTROL VALVE OR DETECTION SYSTEM OUT OF SERVICE MAY ELIMINATE THE FIRE
PROTECTION CAPABILITIES OF THE SYSTEM. PRIOR TO PROCEEDING, NOTIFY ALL AUTHORITIES HAVING JURISDICTION.
CONSIDERATION SHOULD BE GIVEN TO EMPLOYMENT OF A FIRE PATROL IN THE AFFECTED AREAS.
After a fire, verify that the fire is OUT and that placing the system out of service has been authorized by the appropriate Authority
Having Jurisdiction.
Sprinkler systems that have been subjected to a fire must be returned to service as soon as possible. The entire system must be
inspected for damage and repaired or replaced as necessary.
A. If All System Components Are Operational:
1. Open Auxiliary Drain (B.6).
2. Silence alarms (optional).
a: To silence electric alarms controlled by PAR-3 Control Panel (F.8), open panel and press “ALARM SILENCE”
b: To silence electric alarms not controlled by PAR-3 Control Panel (F.8), close Alarm Shut-Off Valve (B.9).
3. To return to service immediately, (when no maintenance or repairs are required) :
a: Close Auxiliary Drain (B.6) if opened in step 1-A. If necessary, open System Drain (G.4) to drain system and/or Test Valve
(B.15) to drain the inlet chamber of the Deluge Valve (A.1).
NOTE: THIS SYSTEM IS PRE-PRIMED WITH WATER. DRAINING THE SYSTEM IS ONLY REQUIRED IF REPAIRS ARE RE-
QUIRED, OR IF THE WATER IN THE SYSTEM IS REPLACED WITH ANOTHER SUPERVISORY LIQUID SUPPRESSANT.
b: Restore system water pressure by opening the Water Supply Valve (F.3). After the system fills with water, Close the Bypass
Isotation Valve (G.3).
c: Open PAR-3 Control Panel (F.8) and press “RESET”.
d: Open Alarm Shut-Off Valve (B.9) (If it was closed in step B-2 above).
e: Verify that all valves are secured in their normal operating position. (Refer to Figure 1)
B. If it is necessary to remove the SUREFIRE® Single Interlocked Pre-Primed Preaction system from service:
1: Close the Main Water Supply control Valve (D.1).
2: Close Priming Valve (B.1) (optional). If necessary, open System Drain (G.4) to drain system and/or Test Valve (B.15) to drain
the inlet chamber of the Deluge Valve (A.1). Close the Maintenance Valve (F.3). If draining the system is necessary, open the
system main drain valve (G.4).
3: Disconnect all power sources to the PAR-3 Control Panel prior to performing any maintenance or repairs to the detection system
(F.9), the panel (F.8), solenoid valves (F.2, F.6), or any electrical component of the system.
C. Perform all maintenance procedures recommended in PAR-3 Owner’s Manual and Technical Data Pages for the individual compo-
nents of the system that has operated.
1. Replace any piping, detectors (F.9), or sections of detection cable that have been damaged.
