SUREFIRE operation 1. The activation of the electric detection AND the opening of an automatic sprinkler is necessary to cause the deluge valve actuation. 2. The activation of the electric detection alone will not cause water to enter the system piping. 3. The opening of an automatic sprinkler OR damage to system piping without the detection condition satisfied will activate the "very low air" alarm pressure switch, The normally open solenoid valve (F2) will be activated but water will not enter the system piping. 4. Activation of the electric detection AND the "very low air" alarm pressure switch will activate will activate solenoid valves (F1) & (F2), causing the deluge valve to open and allowing water to enter the system piping. The alarm pressure switch (C1) will activate. Water will flow out of any open sprinklers and/or any openings on the system. 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. 6. 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 deluge 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. 7. Trouble condition on detection zones, 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 deluge 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 N 2-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 N 2-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 - N 2-Blast. No shutoff 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.

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 IN OUT FM-076D-0-125C 4 of 16
SUREFIRE double interlock c/w N 2 Blast Nitrogen generating system Standard equipments (continued) 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 Single interlock preaction system. 5 of 16 FM-076D-0-125C
