For additional reference information refer to:
• National Fire Protection Association (USA): www.nfpa.org
• Fire Industry Association (UK): www.fia.uk.com
The design concentration for Class A and C fires applies to systems designed to meet and comply with
FM5600, and NFPA 2001, Edition 2015 requirements. As such, our customers are reminded and advised:
• In accordance with 4.3.1.2 and 4.3.1.3 of NFPA 2001, Edition 2015, automatic detection and
automatic actuation shall be used. Manual actuation is permitted only if acceptable by the authority
having jurisdiction.
• Designers should also take note of 4.3.5.6 in NFPA 2001, Edition 2015 with regard to discharge
delays.
• The designer should also review A.5.4.2.4 in NFPA 2001, Edition 2015 and confirm that a protected
Class A hazard does not include any Class B materials (flammable or combustible liquids or gases)
which would classify the protected space as a Class B hazard.
• In addition, the designer should refer to section A.5.6 in NFPA 2001, Edition 2015 and confirm that
the protected space does not include electrical equipment that will not be de-energized prior to or at
the time of Agent discharge. Such energized electrical equipment has the potential to act as a
persistent re-ignition source. If electrical equipment cannot be de-energized, the design Agent
concentration shall be at least that required by 5.4.2.5 in NFPA 2001, Edition 2015. In some cases
consideration should be given to the use of extended Agent discharge or higher design Agent
concentration. When exploring these options, keep in mind the possibility of the formation of
combustion and decomposition products. Please contact applications engineering for design guidance
in such instances.

SAFE CYLINDER HANDLING PROCEDURES
Before handling Kidde IGS products, all personnel must be 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; actuation devices; pressure monitoring devices; transportation safety caps, guards, or
shrouds; and anti-recoil devices.
READ, UNDERSTAND and ALWAYS FOLLOW the design, installation, operation and maintenance manuals,
owners manuals, service manuals, etc., that are provided with the individual systems.
The following safety procedures must be observed at all times:
TRANSPORTING CONTAINER
Containers must be shipped securely either upright in steel stillages or horizontally on pallets using a
minimum of 3 bands to secure the container/s to the pallet.
On site, containers must not be rolled, dragged, or slid, nor allowed to be slid from tailgates of vehicles. A
suitable hand truck, fork truck, single cylinder trolley, 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 and the containers
must be secured.
For additional information on safe handling of compressed gas cylinders, see CGA Pamphlet PI titled
“Standard for Safe Handling of Compressed Gases in Containers”. CGA pamphlets may be purchased from
The Compressed Gas Association: http://www.cganet.com
ANTI-RECOIL SAFETY CAP
• Each Agent cylinder is factory equipped with an anti-recoil safety cap installed on the valve discharge
outlet, and securely fixed to the valve via a stainless steel, PVC coated cable to prevent loss. This
device is a safety feature, and will prevent discharge when installed if the cylinder is actuated
accidentally.
• The anti-recoil safety cap must be installed on the valve outlet AT ALL TIMES except when the
cylinders are connected into the system piping.
WARNING
Any area in which inert gas agent is used or stored must be properly ventilated.
A person working in an area where air has become enriched with agent can
become unconscious without sensing the lack of oxygen. Remove the victim to
fresh air. Administer artificial respiration if necessary and summon a physician.
Never dispose of liquefied agent in an indoor work or storage area.
WARNING
Pressurized (charged) cylinders are capable of violent discharge and, as such, are
extremely hazardous. Pressurized cylinders must be handled safely to avoid accidents
that could cause bodily injury, death, or property damage.
WARNING
The instructions contained in this foreword and throughout the manual must be
followed in the exact sequence as written to prevent serious injury, death, or
property damage.

April 2020 iv 06-237619-001
SAFETY TRANSPORTATION CAP, GUARD, OR SHROUD
The Safety Transportation cap, guard, or shroud is factory installed on the cylinder. The safety
transportation cap, guard, or shroud covers the cylinder valve to protect it during transportation and
handling. No attachments (release unit or slave gauge assemblies) are to be connected to the cylinder
valve during shipment, storage, or handling.
INSTALLATION
THIS SEQUENCE FOR CYLINDER INSTALLATION MUST BE FOLLOWED AT ALL TIMES:
1. Install cylinder into bracketing.
2. Remove the Transport cap.
3. Remove the anti-recoil safety cap and connect all cylinder valves into system piping using
appropriately sized discharge hose.
4. Install all pilot hoses, Pilot Line Bleed Valves etc. leaving the release unit available for installation by
the commissioning engineer only.
REMOVAL FROM SERVICE
THIS SEQUENCE FOR CYLINDER REMOVAL MUST BE FOLLOWED AT ALL TIMES:
1. Remove all release units, slave cylinder pressure gauge units, and pilot lines from cylinder valve.
2. Disconnect discharge hose at the valve outlet.
3. Immediately install anti-recoil safety cap on valve outlet.
4. Attach the transport cap to the cylinder/valve assembly.
5. Remove cylinder from bracketing.
WARNING
In order to prevent injury in the event of accidental cylinder discharge, the discharge
hose must be connected to the system piping before attaching to the cylinder valve
outlet.
WARNING
The safety pin for the manual release must be fully inserted and secured using anti-
tamper seal before attempting to fit the release unit to the valve actuation port
WARNING
The cylinder valve anti-recoil safety cap must be immediately available for installation
on the cylinder valve outlet before disconnecting the cylinder discharge hose from
system piping. If the safety cap is missing obtain a new safety cap from Kidde Fire
Systems.
WARNING
Failure to follow all instructions in this manual on the use and handling of system
components could result in serious bodily injury, death, and property damage in the
