Configurations Description
A wet pipe system is a fixed fire-protection system using
piping filled with pressurized water, supplied from a
dependable source. Closed heat sensitive automatic
sprinklers spaced and located in accordance with recognized
installation standards are used to detect a fire. Upon
operation the sprinklers discharge water over a specific area
to control or extinguish the fire. As the water flows through
the system an alarm is activated to indicate the system is
operating. Only those sprinklers immediately over or
adjacent to the fire operate, minimizing water damage.

Cycling Wet Pipe systems are built around the
Viking trim using Flow Control Valves Model H-3 for 1½" (40
mm) diameter (Model H-4 is the Halar
®
Coated version for
use in corrosive environments) and Model H-1 for 2" (50 mm)
diameter and up (Model H-2 is the Halar
®
Coated version for
use in corrosive environments). The valves are rated up to a
maximum of 250 psi WWP (1724 kPa) and are available in
the following diameters:
1½" (40 mm)
2" (50 mm)
3" (80 mm)
4" (100 mm)
6" (150 mm)

Wet Pipe systems are supplied with a
flange–groove Flow Control Valve. Units with a flange–
flange Valve are also available on request.
Release System
The Viking Firecycle
III cycling wet pipe system utilizes a
Viking Flow Control Valve
(A2)
in lieu of the Alarm Check
Valve
and a Firecycle
III Model E-2 Control Panel, together
with additional valves, devices and trim to form a unique
operating system.
In addition to automatically detecting a fire and turning the
system on, Firecycle
III has the added ability to sense when
the fire has been controlled, and automatically turn off the
water flow once a preprogrammed "Soak Timer" has been
satisfied. Should the fire rekindle, the Firecycle
III will
initiate the sequence again. This unique cycling feature will
repeat as long as power is available to the panel, helping to
minimize water usage, water damage, and the danger of
pollution to surrounding areas. Firecycle
III systems are
also "Fail-Safe".

The Firecycle
III Cycling System has several "Fail-Safe"
features, some of which are not available on other wet pipe
systems. Refer to SYSTEM OPERATION for more details.
Installation

Units must be installed in an area not subject to
freezing temperatures or physical damage.
1. Install the
T
OTAL
P
AC
2
unit and connect the system
according to instruction manual and technical data
supplied.
Note:
The drain collector shall be connected to an open
drain. Do not restrict or reduce drain piping.
2. Install the automatic sprinkler piping, detection and
signaling circuits in accordance with applicable NFPA
standards.
3. Conform to local municipal or other codes regarding
installations of fire protection systems.
4. Perform preliminary inspection outlined below prior to
putting system in service.
5. Put the system into operation as outlined below.
Perform the annual inspection sequence and test each
detector and alarm unit (if applicable).
6. If the system does not operate as it should, make the
necessary corrections according to manuals issued or
consult your distributor or
FireFlex Systems Inc
.
7. Make sure that building owner or a delegated
representative has received instructions regarding the
operation of the system.
Preliminary inspection before placing the
system in service
1. Open door to mechanical section. Main Water Supply
Control Valve
(D1)
should be CLOSED. Alarm test
valve
(B5)
must be CLOSED. All gauges
(B11 and
B12)
should show 0 psi pressure.
2. OPEN Emergency Release Valve
(B10),
then Main
Water Supply Control Valve
(D1).
3. Using the built-in contractor's hydrostatic test port (see
TRIM SCHEMATIC for location) once the sprinkler
system
is filled with water, maintain a pressure of
200 psi for 2 hours. Correct leaks if any before
completing test.
4. Connect all detection and alarm audible devices
according to electrical schematics (see TBA field wiring
diagram in PROGRAMMING SECTION).
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 alarm during sustained flow of water (such
as the flow required by an open sprinkler or the system test
