Fire Protection
Systems (Fire Detection Systems)
APPROVAL GUIDANCE FOR FIRE PROTECTION SYSTEMS
APPROVAL CATEGORY: 161.002
APPROVAL GUIDANCE & INFORMATION:
Follow 46 CFR 161.002 and Subchapter J (Electrical) for power
requirements of detection systems. The Coast Guard only approves
the entire detection system. The system must include all
initiating devices, notification devices and power supply systems.
The following is a clarification of the information provided in the 46
CFR 161.002-4b:
Test Standards Required for
Type Approval
All components must pass the environmental tests for control and
monitoring equipment in either
ABS Rules Table 4/11.1 (1996 version) OR Category ENV3 tests of Lloyd’s
Register Type Approval System, Test Specification Number 1 (1990
version).
Documentation required: Test report from an Independent
Laboratory acceptable by the U.S. Coast Guard for testing under 46 CFR
161.002.
Ref: 46 CFR 161.002-4(b)(2) and (3)
All components that are to be installed in locations requiring
exceptional degrees of protection must also pass one of the following:
- the salt spray (mist) test in ABS Rules Table 4/11.1 (1996),
- the salt spray (mist) test in Lloyd’s Register Type Approval
System, Test Specification No. 1 (1990), or
- ASTM B 117-95 for 200 hours and does not show pitting, cracking,
or other deterioration more severe than that resulting from a similar
test on passivated AISI Type 304 stainless steel.
Locations requiring an exceptional degree of protection means a
location exposed to weather, seas, splashing, pressure-directed
liquids, or similar moisture conditions. These locations include--
(1) On deck;
(2) A machinery space;
(3) A cargo space;
(4) A location within a galley or pantry area, laundry, or water closet
which contains a shower or bath; and
(5) Other spaces with similar environmental conditions.
The components must meet the standards as indicted in the table
below. For UL and NFPA standards, we currently accept all later
versions as equivalent. There should be a factory follow-up
service by an independent agency that checks to see components are
manufactured as tested and that monitors modifications to ensure
previous test results are valid.
| Component |
Non-environmental
Standards required by
46 CFR 161.002– 4(b). |
| Control Unit |
Either UL 864, Standard for
Control Units for Fire-Protective Signaling Systems, 1991 (including
revisions through May 1994);
OR both of these:
Factory Mutual Engineering and Research -- Class Number 3820:
Electrical Utilization Equipment, September, 1979, and
NFPA 72,
National Fire Alarm Code, 1993
|
| Heat Detectors |
Either one of the following
standards:
Factory Mutual Engineering and Research -- Class Number 3210:
Thermostats for Automatic Fire Detection, July, 1978
OR
UL 521, Standard for Heat Detectors for Fire Protective Signaling
Systems, 1993 (including revisions through October 1994). |
| Smoke Detectors |
Either one of the following
standards:
Factory Mutual Engineering and Research -- Class Number 3230–3250:
Smoke Actuated Detectors for Automatic Fire Alarm Signaling, February,
1976
OR
UL 268, Standard for Smoke Detectors for Fire Protective Signaling
Systems, 1989 (including revisions through June 1994). |
| Flame Detectors |
Factory Mutual Engineering and
Research -- Class Number 3260: Flame
Radiation Detectors for Automatic Fire Alarm Signaling, September, 1994 |
| Pull Stations |
UL 38, Standard for Manually Actuated Signaling Boxes for Use with Fire-Protective Signaling Systems, 1994. |
| Alarms (horn, bell, or other
audible device) |
46 CFR 161.002-4(b) specifies
the following:
Factory Mutual Engineering and Research (FMER) -- Class Number 3150:
Audible Signal Devices, December, 1974
and
NFPA 72, National Fire Alarm Code, 1993.
The following are
recognized as equivalent for satisfying the CFR requirement for FMER
3150:
UL 464 Audible Signal Appliances (May 11, 1999)
UL 1480 Speakers for Fire Protective Signaling Systems (July 28,
1998). |
| Alarms (visual) |
46 CFR 161.002-4(b) specifies
the following:
NFPA 72, National Fire Alarm Code, 1993.
The following are recognized as equivalent:
UL 1971 Signaling Applications for the hearing Impaired. |
Additional Issues:
The American with Disabilities Act does not currently apply to the
notification equipment for fire protection systems installed on
passenger vessels. Manufacturers can incorporate visual devices
(e.g. strobes) that meet the latest version of UL 1971 for the design
and installation of their fire protective equipment to mitigate the
potential of causing an epileptic seizure.
If part of the system might be installed in a hazardous location (such
as a cargo hold containing hazardous cargoes), one should be aware of
the requirements in 46 CFR 111.105. The list of laboratories for
testing to the requirements in 46 CFR 111.105 is different than those
for testing for type approval of fire detection systems. For
additional information on installation within hazardous locations, go
to the
System
Engineering
Division (CG-5213) website.
Please note that when a reference is made in the Detection Systems
regulations to the Lloyds and ABS standards it does not mean or infer
approval by Lloyds and/or ABS.
APPROVED INDEPENDENT
LABORATORIES: The Coast Guard does not test materials or
systems for approval but rather specifies the required test methods and
minimum performance criteria for approval. Product testing must
be performed by a Coast Guard Accepted Independent Laboratory.
Use the
ACCEPTED
INDEPENDENT
LABORATORY SEARCH ENGINE to find the laboratories that can conduct
the relevant product testing.
SUBMITTAL PACKAGE: Please
submit the follow information in the Submittal Package:
- A cover letter requesting Coast Guard Type Approval of the
equipment.
- Test report(s) from an Accepted Independent Laboratory be
acceptable by the U.S. Coast Guard for testing under 46 CFR 161.002.
- Three original copies of the manual for the system. In
general, the manual should be easy to follow and provide information on
how the system is to installed and maintained. In addition it
should also include a description of the type of system, what type of
faults are indicated within the system, and the limitations of the
system such as the number of detectors allowed on a circuit.
- List of authorized components. (If the component is not listed,
it cannot be installed in the system.)
- Required drawings/plans and specification sheets of the
equipment. The drawings and plans should provide this office with
a description of each component and the application of the components
including their limitations. The drawings should clearly show how
each component is connected to the system.
Please send the Submittal Package and other related information to the
following address:
Commandant (CG-ENG-4)
U.S. Coast Guard
2100 Second Street, S.W. Stop 7126
Washington, DC 20593-7126
Once the equipment has been approved by this office, it will receive
Coast Guard Type Approval and a Certificate of Approval (COA).
The COA will be issued for 5 years.
