batteries fail prior to the operation of the system, all alarms
will be lost but the system will fail-safe and operate like a
standard wet pipe system.
The cycling function of the system will not operate in this
condition, and the system must be manually shut-off.
If power fails while the system is flowing water, the system
will not cycle off and must also be manually shut-off.
2. 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.
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)
and inspectors test
valve. Drain the system piping.
.3 Silence alarms (refer to CONTROL PANEL SECTION
for additional details).
Note:
Electric alarms controlled by a pressure switch
(C2)
installed in the ½" (15mm) NPT connection for a Non-
interruptible Alarm Pressure Switch cannot be shut-off until
the Flow Control Valve is reset or taken out of service.
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.
.4 Replace any detectors or sprinkler heads that have
been damaged, or have been exposed to fire
conditions.
.5 Perform all maintenance procedures recommended in
MAINTENANCE, describing individual components of
the system that has operated.
.6 Return the system to service as soon as possible.
Refer to PLACING THE SYSTEM BACK IN SERVICE.
3. Placing the system back in service
(refer to TRIM SCHEMATIC)
Note:
For additional details, refer to instructions provided in
the Viking Data Book describing the Flow Control Valve,
and other system components.
When the wet pipe system is ready to be placed in service,
verify that all the equipment is adequately heated and
protected to prevent freezing and physical damage.
Note:
For proper operation of the wet system and to
minimize unwanted (false) alarms, it is important to remove
trapped air from the system when filling it with water. Air
trapped in the system may also cause intermittent operation
of the water motor gong during a sustained flow of water
(such as the flow required by an open sprinkler or the
system test valve). Consider installation of auxiliary vents to
facilitate venting.
CAUTION:
Opening of the water supply main control
valve
(A2)
will result in water flow from any openings in
the system.
1. Slowly open the Emergency Release
(B10)
to allow the
system pressure to return to normal.
2. Once the pressure has stabilized, close the Emergency
Release
(B10)
and press the "System Reset" button on
the Firecycle
®
III Control Panel.
Trouble conditions:
Inspections & Tests
It is imperative that the system be inspected on a regular
basis. Refer to INSPECTIONS and TESTS recommended
in current Viking technical Data describing individual
components of the Viking Wet pipe System used.
The frequency of the inspections may vary due to
contaminated water supplies, corrosive or humid
atmospheres as well as the condition of the air supply to the
system. In addition to the instructions herewith, local
Authority Having Jurisdiction may have additional
maintenance, testing and inspection requirements which
must be followed.
WARNING !
Any system maintenance which involves
placing a control valve or detection system out of service
may eliminate the fire protection capabilities of that system.
Prior to proceeding, notify all Authorities Having
Jurisdiction. Consideration should be given to employment
of a fire patrol in the affected areas.
Maintenance
Note:
The owner is responsible for maintaining the fire
protection system and devices in proper operating condition.
For additional information, refer to MAINTENANCE
INSTRUCTIONS provided in current Viking Technical Data
describing individual components of the Viking Preaction
System used.
Where difficulty in performance is experienced, the valve
manufacturer or his authorized representative shall be
contacted if any field adjustment is to be made.
The following requirements are based upon NFPA-25:
Records.
Records of inspections, tests, and maintenance of the
system and its components shall be made available to the
authority having jurisdiction upon request. Typical records
include, but are not limited to, valve inspections; flow, drain,
and pump tests; and trip tests of Flow Control valves.
Acceptance test records should be retained for the life of the
system or its special components. Subsequent test records
should be retained for a period of 1 year after the next test.
