WHY EVERY BOAT NEEDS A SA-340-MARINE CO ALARM
Everyone is at risk for carbon monoxide poisoning! Particularly sensitive are
children, pregnant women, the elderly and people with lung or heart disease or
anemia! Carbon monoxide (CO) is an odorless, colorless gas that prevents the
blood from carrying oxygen to vital organs. CO is 200 times more likely to
replace oxygen in the blood. The Consumer Product Safety Commission
(CPSC) recommends using at least one CO alarm located outside of
sleeping areas. For the best security, locate a CO alarm in each sleeping
area. Safe-T-Alert CO alarms are available for secondary installations.
ABOUT THIS ALARM
Because CO is a colorless, odorless, tasteless and highly poisonous gas; it
can endanger lives even at low levels of concentration. The CO Alarm
will alert you to potentially dangerous situations. The following
symptoms may be related to CO POISONING. Discuss these
symptoms with ALL household members and boat guests:
Mild Exposure: Headaches, running nose, sore or watery eyes, often
described as “flu-like” symptoms.
Medium Exposure: Dizziness, drowsiness, vomiting.
Extreme Exposure: Unconsciousness, brain damage and death.
NOTE: Reported cases of CO gas poisoning indicate that while
victims are aware they are not well, they are disoriented. They are
unable to save themselves by exiting the boat or calling for
assistance. Small children and pets may be affected first.
Your SAFE-T-ALERT Series alarm helps protect your family
members and guests from CO produced while using your Boat. CO
gas is produced when any type of fuel is incompletely burned.
Potential sources of CO in and around your Boat can include gas or
diesel engine exhaust, portable space heaters, galley gas stoves and
ovens, furnaces, defective engine exhaust systems, charcoal,
portable grills, other nearby Boats, portable generators, generator
exhaust, and other gas powered appliances. All produce CO.
The following are also sources of CO that may affect your Boat:
• Extended operation of unvented fuel burning appliances can build
up high CO levels.
• An idling boat or other vehicle in an open area or closed garage.
• Temperature inversions can trap exhaust near the ground and
water.
• CO build up can be caused by reverse/negative venting of fuel
burning appliances including; 1) Clogged, loose or faulty stacks or
chimneys of (clothes dryers, furnaces and water heaters, etc.), 2)
wind direction and/or velocity, 3) simultaneous operation of
multiple fuel burning appliances, and/or exhaust fans.
• Portable Generators on your boat or neighboring boats.
!
WARNING:
LIMITATIONS OF CO ALARMS
THIS ALARM WILL NOT WORK WITHOUT POWER.
DO NOT REMOVE THE 3 VOLT LITHIUM BATTERY
THIS ALARM WILL ONLY INDICATE THE PRESENCE OF
GAS AT THE SENSOR. CO may be present in other areas. MTI
recommends installing CO alarms in all sleeping areas. Do not
block or cover the alarm with any object that can prevent carbon
monoxide from reaching the sensor.
THIS ALARM IS INTENDED FOR USE IN Boats. It does not
monitor external deck areas where CO may be present. It is not
designed to measure compliance with commercial and industrial
standards.
THIS ALARM MAY NOT BE HEARD. The alarm’s loudness is
designed to meet or exceed regulatory standards; however, the alarm
may not be heard if alarms are located in remote locations or behind
closed doors. Persons who are hard-of-hearing, have consumed
alcoholic beverages, taken prescription, non-prescription or illegal
drugs, may not hear the alarm.
THIS ALARM IS DESIGNED TO DETECT CARBON
MONOXIDE. THE ALARM IS NOT DESIGNED TO DETECT
SMOKE, OR FIRE.
THIS ALARM MAY NOT ALARM AT LOW CO LEVELS - It
is not designed to measure compliance with the Occupational Safety
Health Administration (OSHA) commercial or industrial standards.
Individuals with medical problems may consider using warning
devices, which provide audible and visual signals for CO
concentrations under 30 ppm.
THIS ALARM IS NOT A REPLACEMENT FOR
INSURANCE. Always be sure your RV is fully insured.
Warning: Installation of the device should not be used as a
substitute for proper installation, use, and maintenance of fuel-
burning appliances, including appropriate ventilation and exhaust
systems.
DO NOT Install within 5 feet (1.5M) of any cooking appliance.
WARNING: TO REDUCE THE RISK OF CARBON MONOXIDE
POISONING, TEST ALARM OPERATION WHEN NOT IN USE
FOR 10 DAYS OR MORE; AND BEFORE EACH TRIP.

HOW TO PROTECT YOUR FAMILY
CAUTION - The SAFE-T-ALERTTM SA-340-MARINE CO
Alarm is designed to protect individuals from the acute effects of
carbon monoxide exposure in boats. It will not fully safeguard
individuals with specific medical conditions. If in doubt, consult a
medical practitioner.
To protect your family, you should:
INSTALL THE ALARM PROPERLY. Carefully read and
follow ALL the instructions in this manual. Test your unit every
week. Alarms that do not work will not alert you to hazardous
levels of CO. See the section, Test Procedure, in this manual for
further information.
MAKE REGULAR VISUAL INSPECTIONS. Check all
fuel burning equipment including gas water-heaters, galley
gas stoves, space heaters, gas dryers and all pilot lights.
Check the color of the pilot flame. The color should be blue.
MAKE REGULAR VISUAL INSPECTIONS OF THE
ENGINE AND GENERATOR EXHAUST SYSTEMS.
Cracked exhaust systems can allow CO to enter the living
area of your boat.
PROFESSIONALLY MAINTAIN YOUR ENGINE AND
GENERATOR. Although gas engines and generators
produce CO, a poorly tuned engine and generator will
produce greater amounts CO.
KEEP THE COCKPIT AND PASSENGER AREA WELL
VENTILATED. When idling, traveling at slow speeds or
when the canvas is up at any speed, under certain conditions
high CO levels can collect in the open air and can enter
enclosed areas (station wagon effect).
WHERE TO INSTALL
MTI Recommends installing a CO gas alarm in each
sleeping area.
The NFPA and Consumer Product Safety Commission
recommends installing a CO alarm outside the sleeping
area. The FX-4 CO alarm complies with that
recommendation. ‡
INSTALL ALARM at least 4” (101.6 mm) off the floor.
WHERE NOT TO INSTALL
DO NOT INSTALL behind furniture, drapes, curtains, in
closets or areas that will block air flow to the alarm. ‡
DO NOT INSTALL within 12“ (304.8 mm) of opening
windows, hatches, exterior doors, heating or return vents,
or other drafty areas. ‡
DO NOT INSTALL on an outside wall. ‡
NOTE: Older Boats may have little or no insulation and
therefore are draftier. Carefully consider mounting
locations. The following diagrams provide additional alarm
