B. Close Priming Valve (B.1) (optional).
If necessary, open the System Drain
(D.3) to drain system and/or Test
Valve (B.15) to drain the inlet cham-
ber of the Flow Control Valve (A.1).
C. Disconnect all power sources to the
Firecycle® III Panel prior to perform-
ing any maintenance or repairs to
the detection system (E.4, E.5), the
panel (E.3), solenoid valves (E.1,
E.2), or any electrical component of
the system.
3. Perform all maintenance procedures
recommended in Firecycle® III Owner's
Manual and Technical Data Pages for
the individual components of the system
that has operated.
A. Replace any piping, detectors (E.4),
or sections of detection cable (E.5)
that have been damaged.Note: The
complete system operation must be
tested after servicing, changing pro-
gramming, addition or deletion of
system components, or after any
modification, repair, or adjustment to
system hardware or wiring. All com-
ponents, circuits, system operation,
or software functions known to be
affected by a change must be 100%
tested.
B. Replace any sprinklers and/or spray
nozzles that have been damaged or
exposed to fire conditions.
4. Restore AC power to Firecycle® III
Control Panel (E.3). Ensure that stand-
by batteries are charged or charging.
Always connect and turn on AC power
source prior to connecting the standby
batteries. Connecting the standby bat-
teries to the Firecycle® III Control Panel
(E.3) before the AC power is connected
and turned on may damage the panel.
5. Return the system to service. Refer to
Section E: "PLACING THE SYSTEM IN
SERVICE".
10. PLACING THE SYSTEM IN
SERVICE AT INITIAL START-
UP
(Refer to Figures 1 & 2.)
Note: Refer to Firecycle® III Owner's
Manual, and instructions provided in
Technical Data describing the Viking Flow
Control Valve and other system compo-
nents.
To Return the System to Service:
1. Verify that the Firecycle® III Control
Panel (E.3), Detector Circuits, and
Detectors have been properly installed
TECHNICAL DATA
and energized according to instructions
provided in Viking Technical Data and
the Firecycle® III Owner's Manual.
2. Verify that the system has been properly
drained. (When plunger is depressed
on drip check (B.7), no water should
flow.) System Drain (D.3) should be
open. Verify that Emergency Release
(B.11) is closed.
3. Verify that the System Main Water
Supply Control Valve (D.1) is closed
and the Flow Control Valve (A.1) is
trimmed according to current Viking
Trim Charts and schematic drawings for
the system used.
4. 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 pres-
surized up to the closed Priming Valve
(B.1).
5. Close System Drain (D.3) Restore sys-
tem air pressure. Minimum 30 psi for
system water pressure up to 175 psi.
Minimum 50 psi for system water pres-
sure of 175 psi up to 250 psi.
6. Open the Priming Valve (B.1).
7. Reset the Firecycle® III Control Panel
(E.3) (open the panel and press
"RESET").Release Solenoid Valve #1
(E.1) should close. Flow from Release
Solenoid Valve #1 (E.1) to Drain Cup
(B.14) should stop.
8. Open the Flow Test Valve (B.15).
9. Partially open the Main Water Supply
Control Valve (D.1).
10. When full flow develops from the Flow
Test Valve (B.15), close the Flow Test
Valve.
11. Fully open and secure the Main Water
Supply Control Valve (D.1).
12. Verify that the Alarm Shut-off Valve
(B.9) is open and that all other valves
are in their normal operating position.
13. Depress the plunger of Drip Check
(B.7). No water should flow from the Drip
Check when the plunger is pushed.
11. INSPECTIONS AND TESTS
It is imperative that the system be inspect-
ed and tested on a regular basis. Refer to
INSPECTIONS and TESTS recommended
in current Viking Technical Data describ-
ing individual components of the Viking
Firecycle® III-OH System.Where difficulty
in performance is experienced, the manu-
facturer or their authorized representative
shall be contacted if any field adjustment
is to be made.
The frequency of the inspections may
Firecycle III-OH 432c
FIRECYCLE® III-OH CYCLING
DOUBLE INTERLOCKED
PREACTION SYSTEM
vary due to contaminated or corrosive
water supplies or corrosive atmospheres.
For minimum maintenance and inspection
requirements, refer to the National Fire
Protection Association's pamphlet that de-
scribes care and maintenance of sprinkler
systems. In addition, the Authority Having
Jurisdiction may have additional mainte-
nance, testing, and inspection require-
ments that must be followed.
WARNING: Any system maintenance that
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.
12. MAINTENANCE
NOTICE: The owner is responsible for
maintaining the fire protection system and
devices in proper operating condition.
Repairs:
To perform maintenance on Detection
cable or Detectors without taking the entire
system out of service:
Disable input zone #1. Disabling input
zone #1 disables the detection cable and
detectors, leaving the ability to operate the
Preaction System manually by use of the
Emergency Release. The cycling feature
normally provided by the Firecycle®-OH
Detectors will be disabled.
Note: When zone #1 alone is disabled, if it
is necessary to activate the system using
the Emergency Release, do not reset the
Emergency Release. If the Emergency
Release is reset, the system may cycle
off.
If both input zone #1 and input zone #3
are disabled, the system will operate as a
dry system. If air pressure in the system
is reduced, the Flow Control Valve will trip
and water will flow into the sprinkler sys-
tem. The cycling option will be disabled.
To disable input circuits and associated
output circuits for maintenance, refer to
Firecycle® III Owner's Manual and appli-
cable Firecycle® III wiring diagram to de-
termine which output circuits are activated
by each input circuit.
1. Open the Firecycle® III Control Panel.
2. Press and hold TONE SILENCE but-
ton.
3. While holding the TONE SILENCE
button, press the following buttons in
sequence: ALARM SILENCE, ALARM
ACTIVATE, SYSTEM RESET.
A. The zone #1 LED will flash indicat-
ing Zone #1 is selected. To dis-
able zone #1, continue holding the
