Carbon Monoxide Detector Manual (SSCO3-0)

This carbon monoxide alarm is designed to detect carbon 
monoxide from ANY source of combustion. It is NOT designed to 
detect smoke, fire, or any other gas.

WARNING: 

Carbon monoxide alarms are not smoke alarms. This 

carbon monoxide alarm is not a substitute for installing and 
maintaining an appropriate number of smoke alarms in your 
home. 

This CO alarm will not sense smoke, fire, or any poisonous gas 
other than carbon monoxide even though carbon monoxide can 
be generated by fire. For this reason you must install smoke 
alarms to provide early warning of fire and to protect you and 
your family from fire and its related hazards.

This appliance is not to be used, cleaned, or maintained by 
persons (including children over 8) with reduced physical, 
sensory or mental capabilities, or lack of experience and 
knowledge, unless they are under supervision or have been 
given instruction regarding safe use and understand the 
hazards involved.

Children must not play with this appliance.

WARNING: 

This product is intended for use in ordinary 

indoor locations of family living units. It is not designed to 
measure compliance with Occupational Safety and Health 
Administration (OSHA), commercial, or industrial standards. It 
is not suitable for installation in hazardous locations as defined 
in the National Electric Code. 

The installation of this device should not be used as a 
substitute for proper installation, use and maintenance of 
fuel burning appliances, including appropriate ventilation and 
exhaust systems. It does not prevent CO from occurring, nor 
can it solve an existing CO problem.

WARNING: 

This device is designed to protect individuals from 

acute effects of carbon monoxide exposure. It may not fully 
safeguard individuals with specific medical conditions. If in 
doubt, consult a medical practitioner. Individuals with medical 
problems may consider using warning devices which provide 
audible and visual signals for carbon monoxide concentrations 
under 30 PPM.

This carbon monoxide alarm requires a continuous supply of 
electrical power - it will not work without power.

This alarm has not been investigated for carbon monoxide 
detection below 70 PPM.

CAUTION: 

This alarm will only indicate the presence of 

carbon monoxide at the sensor. Carbon monoxide may 
be present in other areas.

WARNING!! 

Actuation of your CO alarm indicates the 

presence of carbon monoxide (CO) which can KILL YOU.  
If alarm signal sounds: 

1. 

Press the mute button

2. 

Call your emergency services (fire department or 911)

3. 

Immediately move to fresh air – outdoors or by an open 
door/window. Do a head count to check that all persons 
are accounted for. Do not reenter the premises nor move 
away from the open door/window until the emergency 
services responders have arrived, the premises have 
been aired out, and your alarm remains in its normal 
condition.

4. 

After following steps 1 – 3, if your alarm reactivates 
within a 24 hour period, repeat steps 1 – 3 and call a 
qualified appliance technician to investigate for sources 
of CO from fuel burning equipment and appliances, 
and inspect for proper operation of this equipment. If 
problems are identified during this inspection have the 
equipment serviced immediately. Note any combustion 
equipment not inspected by the technician and 
consult the manufacturers’ instructions, or contact the 
manufacturers directly, for more information about CO 
safety and this equipment. Make sure that motor vehicles 
are not, and have not been, operating in an attached 
garage or adjacent to the residence.
