CHAPTER 1: Introduction
BASIC SAFETY INFORMATION
Dangers, Warnings, and Cautions alert you to important operating instructions or to potentially hazardous situations. Pay special attention to these items.
THIS IS NOT A SMOKE ALARM! This CO Alarm is designed to detect carbon monoxide from ANY source of combustion. It is NOT designed to detect smoke, fire, or any other gas.
This CO Alarm is approved for use in single­family residences. It is NOT designed for marine use.
This CO Alarm will only indicate the presence of carbon monoxide gas at the sensor. Carbon monoxide gas may be present in other areas.
The Silence Feature is for your convenience only and will not correct a CO problem. Always check your home for a potential problem after any alarm. Failure to do so can result in injury or death.
IMPORTANT!
IMPORTANT!
IMPORTANT!
CAUTION!
WARNING!
This CO Alarm can not operate without continuous electricity. It does not operate during a power failure.
NEVER ignore your Carbon Monoxide Alarm if it alarms. Refer to “What To Do If Your CO Alarm Alarms” for more information. Failure to do so can result in injury or death.
Test the CO Alarm once a week. If the CO Alarm ever fails to test correctly, have it replaced immediately! If the CO Alarm is not working properly, it cannot alert you to a problem.
This product is intended for use in ordinary indoor locations of family living units. It is not designed to measure CO levels in compliance with Occupational Safety and Health Administration (OSHA) commercial or industrial standards. Individuals with medical conditions may consider using warning devices which provide audible and visual signals for carbon monoxide concentrations under 30 ppm.

HOW YOUR CO ALARM WORKS
General Information
Leave your CO Alarm plugged in year -r ound. CO problems can occur any time during the year, and this alarm can only alert you if it is plugged in and receiving power.
This CO Alarm is intended for use in a standard, unswitched 120V AC wall outlet. It is not intended for use in extension cords, power strips, or outlets controlled by a switch or dimmer. These may not provide continuous power to the unit. When fully powered, it samples the air and takes a new reading about every second. A microchip inside the unit stores each reading, and remembers the levels of CO it has been exposed to over time. The unit goes into alarm mode when it has been exposed to a “critical” level of CO (measured in parts per million or “ppm”) within a specified time (measured in minutes). When the unit is in alarm mode, the Digital Display will show the levels of CO, measured in parts per million, present. This Carbon Monoxide Alarm features a permanently installed sensor , thr ee color ed indicator lights, and an 85 dB alarm horn. It also has a silence feature to temporarily quiet the alarm horn.
Malfunction Warning
This unit performs self-diagnostic tests approximately every second. If the Alarm malfunctions, it should be replaced immediately.

WHAT THE DIGITAL DISPLAY CAN SHOW YOU
The Digital Display is designed to indicate estimated carbon monoxide levels in a residential environment. It is not intended for use as an industrial or commercial grade meter. The Digital Display shows the amount of carbon monoxide (measured in parts per million) the unit is sensing. An average, healthy adult should not feel symptoms when the unit first alarms. However, infants, the unborn, and people with cardiac or respiratory diseases may be more sensitive to CO exposure. See “What To Do If Your CO Alarm Alarms” for complete details on how to respond to an alarm.

“888” is displayed briefly at power up, or when testing the CO Alarm. Until the CO alarm detects at least 30 ppm of CO, it will not display a reading.
It will only display levels of carbon monoxide 30 ppm or higher. The unit is calibrated to sound an alarm before 240 minutes have passed when
exposed to this level. The unit is calibrated to sound an alarm before 50 minutes have passed when
exposed to this level. At this level, an average healthy adult may feel headache within 90 minutes.
The unit is calibrated to sound an alarm before 15 minutes have passed when exposed to this level. This level may be life threatening to a normal healthy adult within three hours.
Over 450 ppm of CO has been detected. Evacuate immediately!
When Checking Peak CO Level
Display Shows... What It Means...
Highest level of CO detected since the last time Peak was cleared
The peak reading lets you check if there was CO detected while you were away from home. In case of a CO alarm, it shows the emergency responder or technician how high CO levels were before they arrived.

THE PEAK CO FEATURE
This feature lets you check the highest level of CO detected since you cleared the Peak memory. This feature also helps a CO investigator. Since you should ventilate your home after any alarm—and since CO dissipates in fresh air— CO levels may drop well below alarm levels by the time investigator arrives.
To check Peak CO:
1. Press and release the Test/Silence button until the dash scrolls to “PEAK”.
2. Press and hold the Test/Silence button to display the peak CO level.
To clear Peak CO:
1. Press and release the Test/Silence button until the dash scrolls to “CLEAR PEAK.”
2. Press and hold the Test/Silence button until the display shows “CLr.”
NOTE:
The peak CO level will be saved, even after a power interruption, until you clear it.

Examples of when to use the Peak CO Feature:
• To check if CO was detected while you were away on vacation.
• To check the highest level of CO recorded during an alarm, especially if you were not home when it started to alarm.
• To show an emergency responder or qualified appliance technician the highest level of CO detected before they arrived.
IMPORTANT!
DO NOT clear the peak CO reading if you plan to call someone to investigate a CO problem! Clear the peak CO reading only after the investigator has checked your home.
