This alarm detects products of combustion using photoelectric technology 
and carbon monoxide using an electrochemical cell. Many times throughout 
this User Guide, we will refer to Carbon Monoxide as “CO.” 
This alarm is acceptable for use near kitchens or cooking areas but can 
be used in all other residential applications where a smoke or CO alarm is 
required.
After ten (10) years of cumulative power up, this unit will “chirp” two times 
every 30 seconds. This is an "operational end of life" feature which will indi-
cate that it is time to replace the alarm.
To help identify the date to replace the unit, a label has been affixed to the 
side of the alarm. Write the “Replace by” date (10 years from initial power 
up) in permanent marker on the label prior to installing the unit.
Product Features and Specifications:
• Temperature: Operating Range: 40°F (4.4°C) to 100°F (37.8°C) 
• Humidity: Operating range: 10-95% non-condensing 
• Audible Alarm: 85+ dB at 10’ @ 3.4±0.5 KHz pulsing alarm 
• Smoke Sensor: Photoelectric 
• CO Sensor: Electrochemical
Two labels have been provided that have important information on what 
to do in case of a CO alarm. Place one label next to the alarm after it is 
mounted, and one near a fresh air source such as a door or window.
