The 5800CO is a 3V battery powered wireless carbon monoxide (CO)
detector intended for use with Honeywell alarm systems that support 5800 Series
wireless devices. It provides early warning when its electrochemical sensing
technology measures carbon monoxide levels in the air. The 5800CO is
specifically designed for system operation and is fully listed to UL 2075 as a
system supervised detector.* It contains a piezoelectric horn which generates
the ANSI S3.41 temporal 4 pattern in an alarm condition.
 The detector consists of an electrochemical carbon monoxide sensor
assembly coupled with a wireless transmitter. The transmitter can send alarm,
trouble, end-of-life, tamper and low battery condition messages to the alarm
panel.
Since there are no holes to drill or wires to run, you can
preserve the beauty of the home or building while protecting its occupants from
harmful carbon monoxide gas. The 5800CO is an ideal carbon monoxide detector for
difficult to wire locations, applications where room aesthetics are critical or
where hazardous materials exist.
What is Carbon Monoxide and How Can it Harm
Consumers?
Carbon monoxide (CO) is an odorless, colorless, tasteless
and highly toxic gas that is produced when fuels such as wood, gasoline,
charcoal and oil are burned with insufficient air. The majority of residential
and commercial fatalities caused from these fuels come from heating systems,
engine powered tools and charcoal grills. Carbon monoxide is harmful when
inhaled because it displaces oxygen in the blood and deprives the heart, brain
and other vital organs of oxygen. Large amounts of CO can overcome a person in
minutes without warning—causing them to lose consciousness and suffocate.
The 5800CO is designed to warn the end-user well before the CO
reaches a fatal level. The detector’s CO sensitivity is evaluated to UL
2034. 
Key Features
Electrochemical Sensing Technology -
Electrochemical detectors are the newest, most refined CO detectors available
and provide the most accurate measurement of CO concentration obtainable. They
can take readings from low levels that may be hazardous over long periods of
time to high concentrations that present an immediate danger.
Local Sounder - A built-in piezoelectric horn
generates the ANSI S3.41 temporal 4 pattern in an alarm condition. The local
sounder will also alert the end-user of other conditions such as low battery,
detector trouble and end-of-life.
LED Status Indicators - Dual LEDs provide local
visual indication of the detector’s status–including normal operation, alarm,
low battery, trouble and end-of-life.
End of Life Timer - When the detector has reached
the end of its life, the detector will send a trouble signal to the panel. This
indicates that the CO sensor inside the detector has passed the end of its life
and the detector needs to be replaced. The detector’s lifespan is approximately
six years from the date of manufacture.
Full Supervision - The 5800CO is fully supervised
to monitor for low battery, case tamper and trouble conditions.
Test/Hush Button - This dual purpose button
allows the end-user to perform periodic testing of the detector. In the event of
a CO alarm, this button will silence the local sounder alarm for a five minute
period. Note: the Hush feature will not operate at levels above 350 ppm (parts
per million) carbon monoxide.
Versatile Mounting - Whether you choose to affix
the detector to the ceiling or a wall, mounting is made simple with the enclosed
hardware. The mounting base has large mounting ports, which accommodate drywall
anchors for easy surface mounting.
Tamper Protection and Tamper Resistant Element -
The detector has a built-in tamper switch that can communicate back to the
control panel in the event it is removed from the base. For an added level of
security, the detector also includes a tamper resistant element that prevents
removal from the base without the use of a tool. |
