  • Page 20: Chapter 1 General Information

    There are a number of limitations to these input parameters which must be observed if accurate results are to be obtained. Kidde ECS Fire Suppression Systems (Kidde ECS System) with HFC-227ea combine an environmentally safe fire suppression agent, highly effective detection devices and specially developed components for fast agent discharge.

  • Page 21: System Description

    1-2.1 General Kidde ECS Systems are used to suppress fires in specific hazards or equipment located where an electrically non-conductive agent is required, where agent cleanup creates a problem, where extinguishing capability with low weight is a factor and where the hazard is normally occupied by personnel.

  • Page 22: 1-2.1.2.2 Unbalanced System Agent Storage Container Temperature Range

    General Information 1-2.1.2.2 Unbalanced System Agent Storage Container Temperature Range In unbalanced systems, where agent flows through the nozzles at varying rates, the agent cylinder storage temperature range is 60°F and 80°F (16°C and 27°C). The latest version of the flow calculation software is written and tested for a 70°F (21°C) agent cylinder storage temperature (for more information see latest version of the Flow Calculation Software User’s Guide 06-236272-001).

  • Page 23: 1-2.2.2 Decomposition

    General Information 1-2.2.2 Decomposition When HFC-227ea is exposed to temperatures over approximately 1300°F (700°C), products of decomposition (halogen acids) are formed. If the HFC-227ea is discharged in 10 seconds or less, flames are rapidly extinguished and the amount of by-products produced is minimal. 1-2.2.3 Cleanliness HFC-227ea is clean and leaves no residue, thereby eliminating costly after-fire clean-up and...

  • Page 24: 1-2.2.5 Storage

    General Information 1-2.2.5 Storage HFC-227ea is stored in steel containers at 360 PSIG at 70°F (25 bar at 21°C) as a liquid with nitrogen added to improve the discharge characteristics. The pressure of the stored HFC-227ea varies substantially with temperature changes, as illustrated in Figure 1-1. When discharged, the HFC-227ea liquid vaporizes at the discharge nozzles and is uniformly distributed as it enters the fire area.

  • Page 26: Chapter 2 Operation

    Operation CHAPTER 2 OPERATION INTRODUCTION This chapter describes the controls and indicators for the Kidde ECS System. SYSTEM CONTROLS AND INDICATORS 2-2.1 General Compressed HFC-227ea liquid is held in the cylinder by a discharge valve. When the discharge valve is actuated by a control head, the valve piston is displaced and the compressed liquid escapes through the discharge port of the valve and is directed through the distribution piping to the nozzles.

  • Page 27: 2-2.3 Post-Fire Operation

    Operation 2-2.3 Post-Fire Operation After an HFC-227ea discharge, qualified fire suppression system maintenance personnel must perform post-fire maintenance as directed in Chapter 6 of this manual. Observe all warnings, especially those pertaining to the length of elapsed time before entering the hazard area. Do not enter a hazard area with an open flame or lighted smoking materials.

  • Page 28: Chapter 3 Component Description

    3-1.1 3 in Cylinder Valve In 2001, Kidde Fire Systems added a 3 inch discharge valve to its product line. This valve replaces the 2½ inch valves previously used on the 600 lb cylinder and is a standard fitting for the 900 lb cylinder assemblies (also new for the year 2001).

  • Page 29: Functional Description

    When the discharge valve is actuated, the compressed liquid agent discharges through the valve outlet and is directed through the distribution piping to the nozzles. The nozzles provide the proper flow rate and distribution of HFC-227ea. The Kidde ECS System is composed of the following components and assemblies: • Cylinder/valve assembly •...

    Post-Discharge Maintenance RECHARGING HFC-227ea CYLINDERS HFC-227ea cylinders may require retest before recharging. See Paragraph 5-5 for details on cylinder retest. FM Approval is based upon the usage of factory CAUTION filled HFC-227ea cylinders. Under no circumstances while performing either cylinder recharge or leak test should a charged cylinder be allowed to free stand without either the charging apparatus attached or the safety cap installed.
