13. Cleaning Your Alarm
Your Alarm Should be Cleaned at Least Once a Year
You can clean the interior of your alarm (sensing chamber) by using compressed air or a vacuum cleaner hose 
and blowing or vacuuming through the openings around the perimeter of the alarm. The outside of the alarm 
can be wiped with a damp cloth. Use only water to dampen the cloth, use of detergents or cleaners could 
damage the alarm. 
If the alarm is in Fault mode , the alarm may be in need of cleaning. After cleaning, press the button. If the fault 
does not clear, the alarm needs to 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.
 • Never attempt to disassemble the unit to clean inside. This action will void your warranty.
 WARNING:  REINSTALL THE ALARM AS SOON AS POSSIBLE TO ENSURE CONTINUOUS  
PROTECTION.
