Embodiment Construction

[0053] figure 1 A fire suppression system 20 is shown. The system includes an inhibitor source 22 and one or more flow paths 24 to one or more protected locations (also referred to as “hazards”) 26 . Flow path(s) 24 lead from source 22 to outlet 28 at location(s) 26 . An exemplary outlet 28 is an outlet of a discharge nozzle 30 for discharging a discharge stream or stream 32 .

[0054] An exemplary source 22 includes a plurality of inhibitor (reagent) containers 34 . An exemplary configuration is a remote drive configuration in which the pressurized body for each reagent container is located remotely from that container. Exemplary reagents are liquid reagents, and exemplary pressurized bodies are nitrogen and / or argon. figure 1 Each reagent container associated with a driver or pressure body container 36, 38 in a unit 40, 42, 44, 46, respectively, is shown. However, in alternative cases the reagent itself is also a pressurized body (eg an inert gas system) or the pressu...

Abstract

A fire suppression system has a tank unit (40, 42, 44, 46). A tank body has a first port and an interior for storing at least one of fire suppressant and driver gas. A discharge assembly is mounted tothe first port and has a discharge valve (50, 52) and a first monitoring switch or sensor (230 240) having a normally closed output (532) and a normally open output (534). A first monitoring system (100) is coupled to one of the normally closed output and the normally open output. A second monitoring system (340) is coupled to the other of the normally closed output and the normally open output.

Description

[0001] Cross References to Related Applications [0002] The benefit of U.S. Patent Application No. 62 / 773459, filed November 30, 2018 and titled "Fire Suppression System Remote Monitoring," the disclosure of which is hereby incorporated by reference in its entirety as set forth in detail, is claimed. Background technique [0003] The present disclosure relates to fire suppression. More particularly, the present disclosure relates to monitoring of fire suppressant storage tanks. [0004] Liquid fire extinguishing agents have been used for decades. Although some reagents such as hydrofluorocarbons (HFCs) (e.g., Halon 1301 (bromotrifluoromethane) and HFC-227ea (heptafluoropropane)) have been disfavored due to environmental concerns, alternatives are readily available in Commercially available, e.g., as dodecafluoro-2-methylpentan-3-one (1, 1, 1, 2, 2, 4, 5, 5, 5-nonafluoro-4-(trifluoromethyl )-3-Pentanone) (CF 3 CF 2 C(O)CF(CF 3 ) 2 ) (ASHRAE designation FK-5-1-12) and th...
