1.5 Emergency Instructions
(Refer to piping diagram provided)
To take 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 employ a fire
patrol in the affected areas.
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. 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.
.1 Close Water Supply Control Valve (D1).
.2 Open system Main Drain Valve (D3).
.3 Silence alarms (if provided, refer to CONTROL
PANEL SECTION for additional details).
Note: Electric alarms controlled by a pressure switch
installed in the ½" (15mm) NPT connection (C2) for a Non-
interruptible Alarm Pressure Switch cannot be shut-off until
the Deluge Valve (A1) is reset or taken out of service.
.4 For Pneumatic Release Systems, shut-off the air
supply (refer to AIR SUPPLY SECTION).
.5 Close Priming Valve (B1) (optional).
.6 Replace any detectors, pilot heads or fixed
temperature releases that have operated.
.a To drain the hydraulic release piping, pull the handle
of the Emergency Release (B11).
.7 Replace any sprinklers and/or spray nozzles that have
been damaged, or have been exposed to fire
conditions.
.8 Perform all maintenance procedures recommended in
MAINTENANCE, describing individual components of
the system that has operated.
.9 Return the system to service as soon as possible.
1.6 Placing the system back in service after
operation:
(refer to TRIM SCHEMATIC)
.1 Verify that the system has been properly drained (in
cycling systems, System Main Water Supply Control
Valve (D1) should be CLOSED). System Main Drain
Valve (D3) should be OPEN. Verify that Emergency
Release (B10) is CLOSED. Priming Valve (B1) should
be CLOSED except for the electrical release system
where is should be OPEN.
.2 f Hydraulic Release System: Verify that the
Inspectors Test Valve and any auxiliary drains are
closed.
f Pneumatic Release System: Restore pneumatic
pressure. Maintain 30PSI (207 kPa) or 50 PSI (345
kPa) as required by the Pneumatic Actuator (F3) and
refer to TABLE 1 above for pressures.
f Electric Release System: Reset the control panel.
Solenoid valve (F1) should close. Flow from the
solenoid valve to the drain manifold should stop.
.3 Open Priming Valve (B1) (except for electric release
system which is already open).
f Hydraulic Release System: Verify that the pressure
on Priming Water Pressure Gauge (B11) indicates that
the priming chamber is pressurized with system Water
Supply Pressure (B12).
.4 Open Flow Test Valve (B6).
.5 Partially open Main Water Supply Valve (D1).
.6 When full flow develops from Flow Test Valve (B6),
close the Flow Test Valve. Verify that there is no flow
from the System Main Drain Valve (D3).
.7 Close the System Main Drain Valve (D3).
.8 Fully open and secure the Main Water Supply Control
Valve (D1).
.9 Verify that the Alarm Test Valve (B5) and all other
valves are at their NORMAL operating position.
.10 Depress the plunger of Drip Check (B7). No water
should flow from the Drip Check when the plunger is
pushed.
