Kidde®ECS™
Fire Suppression System
Designed for use with 3M™ Novec™ 1230 Fire Protection Fluid
900 lb. Cylinder (Marine Applications)
DESCRIPTION
Kidde®ECS™ Fire Suppression System 900 lb. cylin-
ders store 3M™ Novec™ 1230 Fire Protection Fluid
super-pressurized with dry nitrogen to 360 PSIG at 70°F
(2.48 Mpa at 21°C). The cylinders are painted red and
are equipped with a 3-inch pressure differential valve,
pressure gauge, optional liquid level indicator and
optional low-pressure switch assembly. The safety burst
disc is also located on the cylinder head.
OPERATION
The agent storage container discharges when the actua-
tion assembly operates, causing the pressure differential
valve to open. All of the Kidde actuators may be used to
actuate the 900 lb. cylinder. The only exception is the
P/N 82-486500-010, which is not compatible with this cyl-
inder valve.
INSTALLATION
The container is installed in a vertical position with the
valve assembly pointing up. Interconnection to discharge
piping is 3-inch NPT. Interconnection can be via a 3-inch
flex hose (P/N 06-118225-001) or via a suitably pressure
rated groove style fitting.
The container is secured in place by two (2) mounting
brackets (P/N 06-236125-001) or by two (2) cylinder cra-
dles (P/N 06-118300-001), which must be fixed to a solid
wall or strut assembly. Once the container is securely
mounted, connect it to discharge piping per the directions
in the latest revision of the Design, Installation, Operation
and Maintenance Manual (P/N 06-236559-001).
An optional cylinder supervisory pressure switch (P/N 06-
118262-001) can be installed on the cylinder valve in the
field if required. This cylinder supervisory pressure switch
has a 1/8-inch NPT connection, which is used on the 3-
inch valve only. For cylinder valves manufactured prior to
May 1, 2013, use supervisory pressure switch P/N 06-
118263-001.

MAINTENANCE
According to NFPA standards the following inspection
and/or maintenance procedure must be scheduled as
listed below and performed upon the occurrence of any
event which might affect the reliability of the system.
QUARTERLY INSPECTION
1. Check the pressure gauges of each agent storage
container. If the pressure gauge indicates a loss in
pressure of 10% or more, then it shall be recharged
or replaced. Pressure varies with temperature, and
this must be taken into account when checking the
pressure gauge.
2. Check all components, including supporting hard-
ware, and tighten, repair or replace as required.
3. Replace any component if at all in doubt of its ability
to perform properly.
SEMI-ANNUAL INSPECTION
Qualified personnel are to determine the amount of agent
in all containers. The optional liquid level indicator may
be used to measure agent supply and compare it to the
original net weight which is marked on the container
label. If the measured net weight is less than 95% of the
original charged weight the container should be
recharged or replaced.
Inspect all piping, fittings and nozzles for looseness, dirt
or other damage. All outlet piping must be clean and free
of dirt, chips, fillings and other foreign material that may
cause the system to become inoperative or ineffective at
the time of discharge.
