manual and Compressed Gas Association* pamphlets C-1, C-6 and P-1:
• C-1, Methods for Hydrostatic Testing of Compressed Gas Cylinders.
• C-6, Standards for Visual Inspection of Compressed Gas Cylinders.
• P-1, Safe Handling of Compressed Gases In Containers.
*CGA pamphlets are published by: http://www.cganet.com.
• Standard of the National Fire Protection Association No. 2001, titled Clean Agent Fire Extinguishing
Systems.
• All instructions, limitations, etc. contained in this manual, 06-236115-001.
• All information contained on the system container nameplate(s).
The new design concentration for Class A and C fires applies to systems designed to meet and comply with
UL 2166 and NFPA 2001, 2012 Edition guidelines. As such, our customers are reminded and advised:
• The applicable best practice that these systems use automatic actuation;
• Designers should also take note of clause 4.3.5.6 in NFPA 20011, 2012 Edition, with regard to time
delays;
• The designer should also take note of A.3-4.2.4 in NFPA 2001, 2000 Edition and confirm that the
hazard protected does not include any identifiable fire accelerants, which would classify the area as
a Class B hazard;
• In addition, the designer should refer to section A.3-6 in NFPA 2001, 2000 Edition and confirm that
the area does not include a material number of power or energized cables in close proximity that
would predicate the usage of a different design concentration. Please contact applications engineering
for design guidance in this instance.
1. Clause 2-3.5.6.1 in NFPA 2001, 2000 Edition states: “For clean agent extinguishing systems, a pre-discharge
alarm and time delay, sufficient to allow personnel evacuation prior to discharge, shall be provided. For hazard
areas subject to fast growth fires, where the provision of a time delay would seriously increase the threat to life
and property, a time delay shall be permitted to be eliminated.”
2. A.3-4.2.4 in NFPA 2001, 2000 Edition states: “…Hazards containing both Class A and Class B fuels should be
evaluated on the basis of the fuel requiring the highest design concentration.”
3. A.3.6 in NFPA 2001, 2000 Edition states in part: “...Energized electrical equipment that could provide a prolonged
ignition source shall be de-energized prior to or during agent discharge. If electrical equipment cannot be de-
energized, consideration should be given to the use of extended agent discharge, higher initial concentration,
and the possibility of formation of combustion and decomposition products. Additional testing can be needed on
suppression of energized electrical equipment fires to determine these quantities...”

SAFETY BULLETIN 1; MARCH 2, 1987
SUBJECT: SAFE CYLINDER HANDLING PROCEDURES
BEFORE handling Kidde system products, all personnel must be thoroughly trained in the safe handling of
the containers as well as in the proper procedures for installation, removal, filling, and connection of other
critical devices, such as flex hoses, control heads, discharge heads, and anti-recoil devices.
READ, UNDERSTAND and ALWAYS FOLLOW the operation and maintenance manuals, owner’s
manuals, service manuals, etc., that are provided with the individual systems.
The following safety procedures must be observed at all times:
Moving Container: Containers must be shipped compactly in the upright position, and properly secured
in place. Containers must not be rolled, dragged or slid, nor allowed to be slid from tailgates of vehicles. A
suitable hand truck, fork truck, roll platform or similar device must be used.
Rough Handling: Containers must not be dropped or permitted to strike violently against each other or
other surfaces.
Storage: Containers must be stored standing upright where they are not likely to be knocked over, or the
containers must be secured.

SAFETY BULLETIN 2; MAY 1, 1993
SUBJECT: SAFE CYLINDER HANDLING PROCEDURES
FOR PRESSURIZED CYLINDERS
BEFORE handling Kidde system products, all personnel must be thoroughly trained in the safe handling of
the containers as well as in the proper procedures for installation, removal, filling, and connection of other
critical devices, such as flexible hoses, control heads, and safety caps.
READ, UNDERSTAND and ALWAYS FOLLOW the operation and maintenance manuals, owner’s
manuals, service manuals, and other information that is provided with the individual systems.
THESE INSTRUCTIONS MUST BE FOLLOWED IN THE EXACT SEQUENCE AS WRITTEN TO PREVENT SERIOUS
INJURY, DEATH OR PROPERTY DAMAGE.
SAFETY CAP
•Each
HFC-227ea cylinder is factory equipped with a safety cap installed on the valve outlet, and
securely chained to the valve to prevent loss. This device is a safety feature, and will provide
controlled safe discharge when installed if the cylinder is actuated accidentally.
• The safety cap must be installed in the valve outlet AT ALL TIMES except when the cylinders are
connected into the system piping or being filled.
• The safety cap is intentionally chained to the cylinder valve to prevent loss while in service and must
not be removed from its chain.
PROTECTION CAP
A protection cap is factory installed on the actuation port and securely chained to the valve to prevent loss.
The cap is attached to the actuation port to prevent tampering or depression of the actuating pin. No
attachments (control head, pressure control head) are to be connected to the actuation port during
shipment, storage, or handling.
INSTALLATION
THIS SEQUENCE FOR CYLINDER INSTALLATION MUST BE FOLLOWED AT ALL TIMES:
1. Install cylinder into bracketing.
2. Remove safety cap and connect all cylinder valves into system piping using flex hose or valve outlet
adapter.
3. Remove protection cap and attach control heads, pressure control heads, pilot loops, etc., as
required.
WARNING
Pressurized (charged) cylinders are extremely hazardous and if not handled properly are
capable of violent discharge. This will result in serious bodily injury, death and property
damage.
WARNING Discharge hoses or valve outlet adapter must be connected into system piping before
attaching to cylinder valve outlet to prevent injury in the event of discharge.
WARNING Control heads must be in the set position before attaching to the cylinder valve actuation
port, in order to prevent accidental discharge.

06-236115-001 v October 2014
REMOVAL FROM SERVICE
1. Remove all control heads, pressure operated heads, and pilot loops from cylinder valve, and attach
protection cap to actuation port.
2. Disconnect cylinders from system piping at the valve outlet. Disconnect valve outlet
adapter, if used.
3. Immediately install safety cap on valve outlet.
4. Remove cylinder from bracketing.
WARNING Do not disconnect the cylinder from system piping if the safety cap is missing. Obtain a
new safety cap from Kidde.
WARNING Failure to follow these instructions, and improper use or handling, may cause serious
bodily injury, death, and property damage.

CHAPTER 1
GENERAL INFORMATION
1-1 INTRODUCTION
Kidde Fire Systems®ECS Fire Suppression Systems with HFC-227ea Agent are listed by
Underwriters Laboratories, Inc. (UL) and Approved by Factory Mutual (FM). These systems are
designed for total flooding in accordance with NFPA 2001, Standard on Clean Agent Fire
Extinguishing Systems. These systems have been tested to the limits established jointly by UL
and FM. In any situation not specifically covered by this manual, the application and installation
of the system must meet the requirements of the standards as stated. In any case, all
installations must meet the requirements of the local Authority Having Jurisdiction (AHJ).
The complexity of two-phase flow does not allow for any simple method of manual HFC-227ea
calculation. For this reason, the flow calculations and design criteria described in this manual
have been incorporated into the latest version of the flow calculation software program. The
calculations are based on conserving mass, energy and momentum in the pipe network. The
routine calculates the flow in quasi-steady state steps from the initiation of the discharge to
the final gas blowdown. This is a significantly more rigorous treatment than the traditional
Halon NFPA 12A method.
The system designer must become thoroughly familiar with the latest version of the Flow
Calculation Software User’s Guide 06-236272-001 in order to learn the proper procedures for
applying the input parameters to the flow program. 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. The resulting rapid suppression of a fire
reduces property damage and products of combustion to the lowest possible level. These
systems are electrically, pressure and/or cable operated, with a normal design discharge time
of less than ten seconds. Agent storage containers can be strategically located throughout a
protected zone, eliminating expensive piping.
