CHAPTER 1: Introduction BASIC SAFETY INFORMATION IMPORTANT! Dangers, Warnings, and Cautions alert you to important operating instructions or to potentially hazardous situations. Pay special attention to these items. IMPORTANT! 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. IMPORTANT! This CO alarm is approved for use in singlefamily residences. It is NOT designed for marine use.
HOW YOUR CO ALARM WORKS General Information 1 Test/Silence Button 2 RED Indicator Light (LED) This CO alarm is designed to be hard-wired and mounted on any standard size wiring junction box, up to 4” diagonal size. When fully powered, this CO alarm 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.
Basic Operation Normal Operation. • Horn is silent. • Red light (LED) is on continuously. During Testing • Horn pattern repeats twice: 4 beeps, pause, 4 beeps, pause. • Red light (LED) flashes once per second during the 10-second test cycle. During An Alarm • Continuous repeating horn pattern: 4 beeps, pause, 4 beeps, pause. • Red light (LED) flashes once per second while the unit is in alarm. In Silenced Mode • The horn is silent for at least 4 minutes.
CO ALARM SPECIFICATIONS Gas Detection at Typical Temperature and Humidity Ranges: The CO alarm is not formulated to detect CO levels below 30 ppm typically. UL tested for false alarm resistance to Methane (500 ppm), Butane (300 ppm), Heptane (500 ppm), Ethyl Acetate (200 ppm), Isopropyl Alcohol (200 ppm) and Carbon Dioxide (5000 ppm). Values measure gas and vapor concentrations in parts per million.
CHAPTER 2: Installation WHERE TO INSTALL CO ALARMS In a Single-level Home: The Consumer Product Safety Commission (CPSC) recommends the use of at least one CO alarm per household, located near the sleeping area. For added protection, install additional CO alarms in each separate bedroom, and on every level of your home. If your bedroom hallway is longer than 40 feet, install a CO alarm at BOTH ends of the hallway.
WHERE NOT TO INSTALL CO ALARMS DO NOT locate this CO alarm: • In garages, kitchens, furnace rooms, or in any extremely dusty, dirty or greasy areas. • Within 5 feet of any cooking appliance. The alarm should be between 5 and 20 feet from any cooking appliance. • Closer than 20 feet from a furnace or other fuel burning heat source, or fuel burning appliances like a water heater. • In extremely humid areas.
USING THE OPTIONAL LOCKING FEATURES The optional locking features are designed to prevent unauthorized removal of the battery or alarm. It is not necessary to activate the locks in single-family households where unauthorized battery or alarm removal is not a concern. These CO alarms have two separate locking features: one locks the battery compartment, and the other locks the CO alarm to the mounting bracket. You can choose to use either feature independently, or use them both.
3. Push the locking pin through the black dot on the label on the back of the CO alarm. 1. Remove the CO alarm from the mounting bracket. If the unit is locked to the bracket, see the section “To Deactivate the Locking Feature.” 2. Disconnect the power connector by gently prying it away from the back of the CO alarm. 3. Insert a flathead screwdriver under the head of the locking pin, and gently pry it out of the battery compartment lock. (If you plan to relock the battery compartment, save the locking pin.
The Mounting Bracket Lock Tools you will need: • Needle-nose pliers • Standard/Flathead screwdriver TO ACTIVATE THE BRACKET LOCK: 1. Using needle-nose pliers, detach one locking pin from the mounting bracket. TO DEACTIVATE THE BRACKET LOCK: DANGER! ELECTRICAL SHOCK HAZARD. Turn off the power to the area where the CO alarm is installed before removing it from the mounting bracket. Failure to turn off the power first may result in serious electrical shock, injury or death.
2. Pry the CO alarm away from the bracket by turning both the screwdriver and the CO alarm clockwise (right) at the same time. HOW TO INSTALL YOUR CO ALARM This unit is designed to be mounted on any standard wiring junction box up to a 4-inch diagonal size, on either the ceiling or wall. Read “Where to Install” and “Where Not To Install” CO alarms before you begin installation. If a junction box is not already in place, install one using standard #12 or #14 gauge copper wire.
NOTE: A qualified appliance technician is defined as “a person, firm, corporation, or company that either in person or through a representative, is engaged in and responsible for the installation, testing, servicing, or replacement of heating, ventilation, air conditioning (HVAC) equipment, combustion appliances and equipment, and/or gas fireplaces or other decorative combustion equipment.
SINGLE-STATION INSTALLATION 3. Plug the power connector into the back of the CO alarm. Tools needed: Standard/Flathead screwdriver. 4. Position the base of the alarm over the mounting bracket and turn. The alarm can be positioned over the bracket every 60°. Turn the unit clockwise (right) until the unit is in place. DANGER! ELECTRICAL SHOCK HAZARD. Turn off power to the area where you will install this unit at the circuit breaker or fuse box before beginning installation.

The “Latching Alarm” Indicator: KEY: BEDROOM BEDROOM BEDROOM KITCHEN LIVING ROOM GARAGE HALL LATCHING ALARM: Unit was exposed to alarm levels of CO LATCHING NOT ACTIVATED: Unit was not exposed to alarm levels of CO BASEMENT The Latching Alarm Indicator is activated after a CO alarm is exposed to alarm levels of carbon monoxide. After CO levels drop below alarm levels, the red LED will begin to flash once every 5 seconds.
CHAPTER 4: Testing and Maintenance Weekly Testing Push and hold the Test/Silence button on the cover until a loud alarm sounds— 4 beeps, a pause, then 4 beeps. The alarm sequence should last for 10 seconds. If the alarm ever fails to test properly, replace it immediately. If the CO alarm is not working properly, refer to Chapter 10: “Limited Warranty”. WARNING! The Test/Silence button is the only proper way to test the CO alarm.
CHAPTER 5: What You Need To Know About CO What is CO? CO is an invisible, odorless, tasteless gas produced when fossil fuels do not burn completely, or are exposed to heat (usually fire). Electrical appliances typically do not produce CO. These fuels include: Wood, coal, charcoal, oil, natural gas, gasoline, kerosene, and propane. Common appliances are often sources of CO. If they are not properly maintained, are improperly ventilated, or malfunction, CO levels can rise quickly.
Potential Sources Of CO In The Home Fuel-burning appliances like: portable heater, gas or wood burning fireplace, gas kitchen range or cooktop, gas clothes dryer. Damaged or insufficient venting: corroded or disconnected water heater vent pipe, leaking chimney pipe or flue, or cracked heat exchanger, blocked or clogged chimney opening. Improper use of appliance/device: operating a barbecue grill or vehicle in an enclosed area (like a garage or screened porch).
How Can I Protect My Family? A CO alarm is an excellent means of protection. It monitors the air and sounds a loud alarm before Carbon Monoxide levels become threatening for average, healthy adults. A CO alarm is not a substitute for proper maintenance of home appliances. To help prevent CO problems and reduce the risk of CO poisoning: • Clean chimneys and flues yearly. Keep them free of debris, leaves, and nests for proper air flow.
CHAPTER 6: Underwriters Laboratories Inc. UL2034 What Levels of CO Cause an Alarm? Underwriters Laboratories Inc. UL2034 defines 3 specific alarm points by which all residential CO alarms must alarm. They are measured in parts per million (ppm) of CO over time (in minutes). UL2034 Required Alarm Points: • If the alarm is exposed to 400 ppm of CO, IT MUST ALARM BETWEEN 4 and 15 MINUTES • If the alarm is exposed to 150 ppm of CO, IT MUST ALARM BETWEEN 10 and 50 MINUTES.
CHAPTER 7: Troubleshooting Guide DANGER! ELECTRICAL SHOCK HAZARD. Turn off the power to the area where the CO alarm is installed BEFORE removing it from the mounting bracket or checking any electrical connections! Failure to turn off the power first may result in serious electrical shock, injury or death. The following guide can help you identify a potential problem with the installation or operation of your CO alarm. It is not meant to be an all-inclusive list of all CO alarm conditions.
