Installation Guide
After cleaning, test your alarm by using the test button. If cleaning does 
not restore the alarm to normal operation, the alarm should be replaced.
• Never use detergent or other solvents to clean the unit.
• Avoid spraying air freshener, hair spray, or other aerosols near the alarm.
• Do not paint the unit. Paint will seal the vents and interfere with the 
sensor’s ability to detect smoke and CO. 
• Never attempt to disassemble the unit or clean inside. This action will 
void your warranty. 
• The following substances can affect the CO sensor and may cause false read-
ings and damage to the sensor: Methane, propane, isobutane, iso-propanol, 
ethyl acetate, hydrogen sulfide, sulfide dioxides, alcohol based products, 
paints, thinner, solvents, adhesives, hair spray, after shave, perfume, and 
some cleaning agents.
• Move the Smoke/CO Alarm and place in another location prior to performing 
any of the following:
• Staining or stripping wood floors or furniture
• Painting
• Wall papering
• Using adhesives
Storing the unit in a plastic bag during any of the above projects will protect the 
sensors from damage. When household cleaning supplies or similar contami-
nates are used, the area must be well ventilated.
 WARNING: Reinstall the Smoke/CO Alarm as soon as possible  
to ensure continuous protection.
