CO Sentinel Carbon Monoxide Alarm
Should a very high level of carbon monoxide exist, the CO Sentinel will alarm in a few
minutes. However, if small quantities of CO are present or high levels are short-lived,
the microcontroller will accumulate the information and determine when an alarm level
has been reached. This feature eliminates nuisance alarms. For example, in a boat it is
possible to see high levels of CO for a very short time such as when docking or
maneuvering. The CO Sentinel takes this all under consideration by totaling the quantity
of CO detected over a period of time.
The CO Sentinel is programmed to alarm at a COHb level of 10%. SEE TABLE 2.
Features of the CO Sentinel (CMD-4M, CMD-4MR)
The CO Sentinel is designed to meet applicable marine standards. The CO Sentinel is
listed to meet UL 2034, marine requirements.
The CO Sentinel is designed to operate from a 12VDC source. For operation from other
voltage sources, contact the engineering department of Fireboy-Xintex.
The CO Sentinel conducts a self-diagnosis of critical components every 10 seconds.
Should a major component fail, the CO Sentinel will enter a fault mode. Both audible
and visual warning indicators are activated.
The CO Sentinel circuit board is sealed against moisture and corrosion to withstand the
harshest environments and ensure durability.
A re-certification and warranty renewal program is offered by the factory for your
assurance of a properly operating unit. It is highly recommended that the units are sent
in on an annual basis for re-certification.
The CO Sentinel is designed to tell you when your power source has dropped to a level
insufficient for proper operation. The red light will come on accompanied with an
intermittent horn beep. Restore the power to 12V and the unit will return to normal
operation.
Features of the CO Sentinel Deluxe (CMD-4M-RLY, CMD-4MR-RLY)
The deluxe model is designed to interconnect with other deluxe models. If the unit
senses CO at an alarm level, it will communicate with other interconnected units and
send them into alarm. The unit that senses CO will have a distinct LED pattern
compared to the interconnected units. The CO Sentinel Deluxe is designed to connect
up to a maximum of six interconnected units.
The deluxe model is also designed with relay outputs. The relay connection is rated at
12VDC,1A max and can be used to shutdown a generator or other possible carbon
monoxide source, or trigger a remote horn or alarm for example.
