Carbon monoxide alarm procedure 

WARNING: 

The carbon monoxide (CO) alarm indicates the 

presence of CO, which can kill you. If the alarm signal sounds 
four times, pauses for five seconds, and then repeats the 
pattern: 

1.  Press the Test/Hush button at the detector or at the 

control panel. 

2.  Move to fresh air immediately — outdoors or by an open 

door or window. Check that all persons are accounted for. 
Do not reenter the premises or move away from the open 
door or window until emergency services responders have 
arrived, the premises have been aired out, and your 
detector remains in normal condition. 

3.  Call emergency services, the fire department, or 911: 

Phone: 

4.  After following steps 1 to 3, if your detector reactivates, 

repeat steps 1 to 3 and call a qualified appliance 
technician to check for sources of CO from fuel-burning 
equipment and appliances, and to inspect for proper 
operation of this equipment. 

Phone: 

5.  If problems are found during this inspection, have the 

equipment serviced immediately. Note any combustion 
equipment not inspected by the technician and consult the 
manufacturer directly for more information about CO 
safety for the equipment. Make sure that motor vehicles 
are not, and have not been operating in an attached 
garage or adjacent to the premises. 

Information about carbon monoxide 

WARNINGS 

• 

Read these installation instructions in their entirety before 
proceeding. Leave these instructions with the owner/user 
of this CO detection equipment. 

• 

This product is intended for use in indoor locations of 
dwelling units. It is not designed to comply with 
Occupational Safety and Health Administration (OSHA) 
commercial or industrial standards. 

• 

The detector only indicates the presence of CO gas at the 
detector. Carbon monoxide gas may be present in other 
areas. 

• 

Failure to properly install, test, and maintain a CO detector 
may cause it to fail, potentially resulting in loss of life. 

• 

Installation of this detector is not a substitute for proper 
installation, use, and maintenance of fossil fuel-burning 
appliances, including appropriate ventilation and exhaust 
systems. 

• 

To reduce the risk of CO poisoning, test the detector 
operation when not in use for 10 days or more. 

• 

This detector does not operate without electrical power. As 
fires frequently cause power interruption, discuss further 
safeguards with the authority having jurisdiction (AHJ). 

• 

Do not paint the detector.
