CARBON MONOXIDE DETECTORS
Carbon monoxide known as CO is indeed the silent killer.
It is a by-product of combustion. CO is invisible, taste-
less, odorless and is produced by all internal combustion
engines, heating and cooking appliances.
The most common forms of CO on board vessels are the
engines, generator and if applicable, propane heating and
cooking devices.
Never operate these devices when people are sleeping.
A slight amount of CO in the human body over several
hours causes headaches, nausea and symptoms close to
food poisoning, motion sickness or fl u. High concentra-
tions can be fatal within minutes.
HOW THE SYSTEM WORKS
The CO detector uses a mini computer to measure and ac-
cumulate CO levels. Using the principle of "time weighted
averaging" the detector monitors CO concentrations, tem-
perature, humidity and time to calculate COHb levels. To
explain COHb, our bodies prefer to absorb CO to oxygen
and COHb is the absorbed ratio stated in a percent.
If the detector senses high levels of CO the alarm will
sound in a few minutes. If lower levels are sensed, the
detector will accumulate the data and sound an alarm when
the appropriate level is reached. Read and understand the CO
owner's manual in the information pouch.
To turn the CO detector system on:
1. Notice the CO breaker on the 12 volt main DC panel.
It must be turned off in a two-step sequence. This is for
safety purposes. The system should be always left ON.
You must fl ip back the switch cover before you are able
to deactivate the breaker.
The CO circuitry works to its best performance when
continually activated plus it accords advanced warning
when entering an area high in CO.

2. When power is applied to the detector, the power in-
dicator (top) will fl ash on and off, followed by the (red)
lower alarm indicator fl ashing off and on as part of a 8-14
minute warm-up period. The green (top) power indicator
will indicate a solid green when the unit has reached cor-
rect operating temperature. Never operate a cooking device
with the canvas up or the cabin door completely closed to
prevent CO concentration build-up

the test cycle indicators.
4. When an alarm sounds take action immediately. The
danger alarm indicator fl ashes red and the horn beeps 4
times, pauses and repeats the cycle. This indicates a rate
of 10% COHb has been reached.
a. Operate reset/silence button.
b. Call your emergency services (911)
c. Immediately move to fresh air. Do not re-enter the vessel.
until emergency personnel have arrived, aired the vessel
out and the alarm is in a normal condition.
d. After following steps a-c and your alarm reactivates
within a 24-hour period call a qualifi ed technician to inspect
the vessel. Note that the CO detector will clear when the
CO concentration has dropped below 70 ppm.
3. The test cycle should
be activated frequently.
Simply press the button.
When it is released, the
(top) power indicator will
flash off and the lower
indicator light will flash
on. Then, the lower indica-
tor will fl ash off and the
upper indicator light will
come back on.
The top indicator light be-
ing on solid green indicates
normal operation. Refer to
