d. After following steps a-c, if your alarm reactivates within a 24-hour period,
repeat steps a-c and call a qualified appliance technician to investigate for
sources of CO from fuel burning equipment and appliances, and inspect for
proper operation of the equipment. If problems are identified during this
inspection, have the equipment serviced immediately.
NOTE: The CO Sentinel will alarm at 10% COHb. SEE TABLE 2. The alarm will clear
when the COHb % has dropped below 10%.
Nuisance Alarms
Although the CO Sentinel will detect only carbon monoxide in a normal environment,
studies have found that unusually high concentrations of chemicals and/or vapors will
affect the sensor.
The device may be triggered by any number of hydrocarbons at very high levels. These
include toluene, isopropyl alcohol, methyl ethyl ketone, mica, and many adhesives.
Many of these chemicals are the result of outgassing in new boats. While these may be
considered nuisance alarms, levels high enough to create an alarm condition are also
hazardous. Treat these “nuisance” alarms as an actual carbon monoxide alarm
condition. Evacuate and ventilate the area. Before, during, and immediately after
working with any chemicals, make sure enough fresh air ventilation is available.
Limitations
•
This carbon monoxide alarm is designed to detect carbon monoxide gas
from ANY source of combustion. It is NOT designed to detect smoke, fire
or any other gas.
•
The CO Sentinel will not detect carbon monoxide that is not in the vicinity
of the alarm. Carbon monoxide in other rooms or areas will not be
detected. Alarms mounted near obstructions or in ‘dead’ air spaces will
not detect carbon monoxide.
•
The CO Sentinel does not guarantee or imply that CO poisoning will not
occur. Do NOT use the CO Sentinel as a replacement for ordinary
precautions or periodic inspections of equipment. NEVER rely on alarm
systems to save your life, common sense is still prudent and necessary.
•
The audible horn on the CO Sentinel meets UL requirements; however,
the horn may not be heard in remote areas.
INSTALLATION AND OPERATION
•
The nature of an alarm system is to produce an irritating and loud noise.
The audible signal of the CO Sentinel may shock or startle persons near
the alarm. Hearing damage can occur if prolonged exposure to the
audible alarm is allowed.
•
All electric devices have limited life spans and may fail without warning.
Inspect the CO Sentinel on a periodic basis. Do NOT assume that the
CO Sentinel will prevent CO poisoning. It is a supplement-warning device
only.
