Sequence of operation Firecycle®III operation

1. The activation of at least one FireCycle® III detector is necessary to cause the flow control valve actuation.

2. The activation of the detection condition alone will activate the solenoid valves (F1) and (F2), causing the flow control valve to open and allowing water to enter the system piping. The alarm pressure switch (C1) will activate. Water will not discharge into the protected area since all sprinkler heads are closed. The opening of an automatic sprinkler will cause the water to flow out of the system. Water will flow in the protected area until all FireCycle® III detectors have reset (cooled below their set point) After all detectors have been reset, the Firecycle® lll control panel activates the soak timer, allowing the system to discharge water for a pre-determined period of time. When the soak timer has elapsed, the control panel de-energizes the normally closed solenoid valve (F1), allowing the flow control valve to re-prime and close, stopping the flow of water through the piping system. Should a FireCycle® III detector go into alarm, the control panel re-energizes the normally closed solenoid valve and the entire cycle repeats.

3. The opening of an automatic sprinkler OR damage to system piping without the detection condition satisfied will activate the low air supervisory and “very low air” alarm switch (E4) contacts but water will not to enter the system piping. The solenoid valve (F2) will be activated.

4. Operation of the emergency manual release will depressurize the priming chamber, causing the deluge valve to open and allowing water to enter the system piping and water will discharge through any open sprinklers.The alarm pressure switch (C1) will activate.

5. When AC Power and DC power supplied by the back up batteries is lost, the system shall “fail-safe” and function as a dry pipe system. The normally open solenoid will remain open, and the pneumatic actuator is the only device holding the priming water in the priming chamber. When a sprinkler operates, air pressure is lost and the pneumatic actuator opens. Priming water is drained from the priming chamber, causing the flow control valve to open and allowing water to enter the system piping. The alarm pressure switch will activate. Water will flow out of any open sprinklers and/or any openings on the system. The cycling function of the system will not operate in this condition, and the system must be manually shut-off.

6. Trouble condition on FireCycle® III detection zone, or "very low air" alarm zone, or the normally closed solenoid output, disables the normally open solenoid and the pneumatic actuator is the only device holding the priming water in the priming chamber. When a sprinkler operates, air pressure is lost and the pneumatic actuator opens. Priming water is drained from the priming chamber, causing the flow control valve to open and allowing water to enter the system piping. The alarm pressure switch will activate. Water will flow out of any open sprinklers and/or any openings on the system.

N2 Blast® Nitrogen generator system operation 1. The initial air supply fill of the piping system within 30

minutes as per NFPA 13 is accomplished using the “initial fill” air compressor. This compressor is equipped with a factory-adjusted ON/OFF pressure switch which is tied into the sprinkler system piping. It is factory-set at 20 and 35 psi for the cut-in and cut-out pressures respectively. There is a "low air" supervisory pressure switch which monitors system piping air/nitrogen pressure at all times. It is factory-set at 25 psi to provide a "low air" supervisory signal and 23 psi to provide a "very low air" supervisory signal.

2. The nitrogen generation/maintenance air compressor is supplied as an integral part of the STS N2-Blast® Nitrogen Generation System. It is equipped with a factory-adjusted ON/OFF pressure switch which is tied into the nitrogen storage tank. It is factory-set at 65 psi and 75 psi for the cut-in and cut-out pressures respectively. The Viking D-2 Air Pressure Maintenance Device is installed and factory-adjusted to 35 psi (normal system air/nitrogen pressure) downstream of the nitrogen storage tank. As the system continually purges with Nitrogen, the APMD will continually draw from the Nitrogen storage tank to maintain supervisory pressure (35 psi). Should the N2-Blast® generator run for more than 6 hours consecutively, the Leak Detection System (LDS) will automatically shut it down and activate a trouble contact.

3. The air and nitrogen supply systems are fully integrated and fully automatic in the FireFlex - N2-Blast®. No shut-off or bypass valve is required. The nitrogen generator is equipped with a BlastOff® Leak Detection System (LDS). Should the nitrogen generator compressor fail or a leak occur that can not be compensated by the nitrogen generating system, the preaction system air compressor will act as a back-up and start-up at 20 psi system pressure.

The panel is compatible with many types of fire alarm & supervisory devices such as linear heat detectors, spot-type heat and smoke detectors, water flow and release indicators, low and high air pressure switches, manual pull stations.

The releasing control panel also includes an alphanumeric display with 2 lines of 16 characters describing all the system conditions, as well as a set of red and yellow LED lamps individually indicating each of the alarm and trouble conditions of the system

Easy to operate control buttons are also provided to activate and operate the system's various functions.

Releasing circuit disconnect switch

The releasing circuit disconnect switch is used to disable the releasing solenoid. When the key is set to “Disable”, the releasing solenoid will be disconnected from the control panel’s releasing circuit, causing a trouble signal and preventing accidental discharge during maintenance or inspection.

Flow control valve The Viking flow control valve is a quick opening, differential type flood valve with a spring loaded rolling diaphragm clapper. The flow control valve can be used to facilitate manual or automatic on/off control. The Viking flow control valve is an integral part of the Viking Firecycle® System.

The valve is held closed by system water pressure trapped in the priming chamber, keeping the outlet chamber and system piping dry. In fire conditions, when the releasing system operates, pressure is released from the priming chamber. The flow control valve clapper opens to allow water to flow into the system piping.

Water supply control valve The water inlet control valve is a supervised, indicating butterfly valve. Purpose of this vale is to manually shutoff the preaction system.

N2 Blast® Nitrogen generator

South-Tek Systems utilizes Membrane technology in the N2-Blast® Corrosion Inhibiting Systems in order to efficiently separate Nitrogen molecules from the air we breathe. Membrane technology, used in our smaller applications, has a simple air flow design, is wall-mounted and easy to service. PSA technology is more cost effective and energy efficient in larger Fire Protection Systems, those requiring more Nitrogen to compensate for the NFPA “acceptable leak rate”.

BlastOff™ Leak detection system

Unless the leak rate is catastrophic, the supervisory low pressure alarm on the FPS will not activate. Minor leaks cause the air compressor and N2-Blast® to run excessively in order to maintain supervisory pressure. The unnecessary additional run-time decreases the lifespan of the equipment. The Patent Pending BlastOff™ - Leak Detection System is designed to detect significant leaks before they compromise the FPS and the Nitrogen Generation System. It has an internal audible alarm and dry contact for wiring into the Building Monitoring System (BMS) and will also alarm if the air compressor or the N2-Blast® is not working properly.

Nitrogen generator storage cylinder

Type 1 Nitrogen Generation Systems include a 16 gallon Nitrogen receiver tank (12.2”dia x 44.8”H). Nitrogen generated by the N2-Blast® is stored in the tank, and then sent to the sprinkler system through the Nitrogen air pressure maintenance device.

N2 Blast® AutoPurge System™

High purity Nitrogen must be equally distributed throughout the entire sprinkler piping system in order to effectively inhibit corrosion. The Patent Pending AutoPurge System™ provides a low volume, constant purge of Nitrogen within sprinkler piping. The rate in which gas is evacuated from the sprinkler piping is within NFPA guidelines and allows breathing to occur. The AutoPurge System™ also assists in drying out the residual water from a hydro test. Computational Fluid Dynamics modeling proves that this is the most effective way to ensure that high purity Nitrogen reaches all branches within the sprinkler piping. Install one AutoPurge System™ per system at a high point .

There is a Label on one side of the housing that lists the proper setting for a variety of zone sizes. The Label list: Gallons in Zone, and APS Flow Setting. The Flow Setting is labeled from A-E and has three Settings in between each letter.

Nitrogen generator air pressure maintenance device

FIREFLEX® N2 Blast® use the Viking Model D-2 Air Pressure Maintenance Device (APMD) which is a pressure regulator that automatically reduces the supply air pressure to a preset requirement when connected to a constantly maintained air supply.

The APMD is used to regulate the nitrogen pressure to 35 psi in the sprinkler piping at the specified system pressure for FIREFLEX N2 Blast®.
