Water discharges until all Firecycle® detectors have reset
(cooled below their set point). After all detectors have
reset, the Firecycle® III control panel activates the Soak
Timer, allowing the system to flow water for a pre-
determined period of time. When the Soak Timer has
elapsed, the control panel de-energizes the normally
closed Solenoid valve (F2), allowing it to close (the
normally open solenoid (F1) remains energized closed until
the system is manually reset or all power (both AC and
batteries) is lost).
The Flow Control Valve re-primes and closes, stopping the
flow of water through the piping system. Should a
Firecycle® detector go into alarm, the control panel re-
energizes the normally closed solenoid valve (F2) open,
and the entire cycle repeats.
Trouble conditions:
If the detection system is damaged or malfunctions, the
Firecycle III Control panel will go into alarm and the Flow
Control Valve (A2) will open. Water will flow from any
open sprinklers and/or other opening in the sprinkler
piping. The cycling function of the Firecycle III will not
operate in this condition. All alarms will operate normally.
If the AC power fails, the Firecycle III System continues
to operate on the standby batteries. Should both AC and
batteries fail prior to the operation of the system, all alarms
will be lost and the system will need to be manually
actuated. 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
normally open Release Solenoid (F1) will fail open. The
PORV (B14) is already pressurized open, continually
venting the priming chamber of the Flow Control Valve
(A2). The cycling function of the system will not operate in
this condition, and the system must be manually shut-off.
Manual operation:
Anytime the handle of the Emergency Release (B10) is
pulled, pressure is released from the priming chamber;
Flow Control Valve (A2) will open. Water will flow from any
open sprinklers and/or other opening in the sprinkler piping
and alarm devices (C1 & C2) will operate. The cycling
function of the Firecycle III
®
will not operate in this
condition due to the open Emergency Release (B10).
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 Open system Main Drain Valve (D3).
.2 Silence alarms (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 Flow Control Valve (A2) 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 that have been damaged.
.5 Replace any sprinklers and/or spray nozzles that have
been damaged, or have been exposed to fire
conditions.
.6 Perform all maintenance procedures recommended in
MAINTENANCE, describing individual components of
the system that has operated.
.7 Return the system to service as soon as possible.
3. Placing the system back in service after
operation:
(refer to TRIM SCHEMATIC)
.1 Both the Main Water Supply Control Valve (D1) and the
Priming Valve (B1) should remain open.
.2 System Main Drain Valve (D3) should be OPEN. Verify
that Emergency Release (B10) is CLOSED. Verify that
the system has been properly drained.
.3 Reset control panel. Alarm devices should stop. N.O.
release solenoid valve (F1) is de-energized.
.4 Close the System Main Drain Valve (D3).
.5 Make sure the Main Water Supply Control Valve (D1) is
fully open.
.6 Verify that the Alarm Test Valve (B5) and all other
valves are at their NORMAL operating position.
.7 Depress the plunger of Drip Check (B7). No water
should flow from the Drip Check when the plunger is
pushed.
