Sequence of operation Preaction operation 1. The activation of the detection condition is necessary to cause the deluge valve actuation. 2. Detection condition: Single zone (the operation of one detector in the protected area is required to fulfill the detection condition). Crossed zone (the operation of two detectors in the protected area is required to fulfill the detection condition). 3. The activation of the detection condition alone will activate the solenoid valve (F1) open, causing the deluge 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. When a sprinkler head opens, water will flow. 4. The opening of an automatic sprinkler OR damage to system piping without the detection condition satisfied will activate the low air supervisory (E4) switch contact but will not allow the water to enter the system piping. 5. 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. 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 10 and 20 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 12 psi to provide a "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 20 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 (20 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 10 psi system pressure.

Standard equipment Deluge valve The Viking Model F-1 Deluge Valve is a quick-opening, differential diaphragm flood valve with one moving mechanism. The deluge valve is used to control water flow in preaction sprinkler systems. 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 deluge valve clapper opens to allow water to flow into the system Preaction riser check valve The Viking 1-½ and 2 spring loaded In-Line check valve is a general purpose rubber-faced check valve approved for use in fire-service systems. The Spring Loaded In-Line check valve is manufactured with a brass body, brass seat, and a rubber-faced clapper assembly. The Viking 3, 4 and 6 Easy Riser Swing check valve is a general purpose rubber-faced check valve approved for use in fire service systems. The valve is for use in preaction system risers. 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. Solenoid valve The high pressure solenoid valve is a two-way type with one inlet and one outlet. It is a packless, internal pilot operated valve, suitable for use in releasing water pressure from the priming chamber of Viking Deluge Valves. The solenoid valve has floating diaphragm construction, which requires a minimum pressure drop across the valve to operate properly. IN OUT 3 of 14 FM-076D-0-115D
Standard equipments (continued) Low air supervisory switch The low pressure switch monitors the pressure within the sprinkler piping should a loss of the air below 12 Psi occur. The pressure switch contacts transfer indicating supervisory signal. POTTER PS40-1A Alarm pressure switch The alarm pressure switch monitors the water flow within the sprinkler piping. Should the Deluge Valve clapper opens to allow water to flow into the sprinkler piping. The alarm pressure switch will activate, indicating a water flow signal POTTER PS10-1A 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. 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 20 psi in the sprinkler piping at the specified system pressure for FIREFLEX N2 Blast system. FM-076D-0-115D 4 of 14
Optional preaction equipment Shut-off valve & sight glass (optional) The Shut-off Valve & Sight Glass Option is intended to be used for applications where testing of the system operation without filling the sprinkler piping network is desirable and where it is critical that all functions of the preaction system be tested under actual discharge conditions.
