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!

CAUTION!

WARNING!

This unit does not work without power. If the AC power fails, the battery back-up will power the alarm for at least 8 hours provided the 9V battery is fresh and correctly installed.

NEVER ignore your Carbon Monoxide Alarm if it alarms. Refer to “What To Do If Your CO Alarm Sounds” 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.

audible alarm for test, alarm, and unit malfunction warning

General Information

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. 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).

General features: This alarm features a

permanently installed sensor , a red indicator light (LED), and an 85 dB alarm horn.

9V Battery Back-Up. If AC power is interrupted,

the CO alarm will continue to operate, provided the 9V battery is fresh and correctly installed.

Silence Feature. The silence feature temporarily

quiets the alarm.

Malfunction Warning

This unit performs self-diagnostic tests approximately every second. If the alarm malfunctions, it should be replaced immediately.

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.

Low Battery Warning, AC Power ON:

• The horn “chirps” once a minute.

• Red light ﬂashes once each time the horn “chirps”.

Low Battery Warning AC Power OFF:

• The horn “chirps” once a minute.

• Red light ﬂashes once each time the horn “chirps”.

For a detailed list of all light and horn pattern combinations, see pages 24-25.

In Silenced Mode

• The horn is silent for at least 4 minutes.

• Red light (LED) ﬂashes rapidly, once every second on the initiating alarm only.

CO ALARM SPECIFICATIONS

Gas Detection at Typical Temperature and Humidity Ranges:

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.

Required Alarm Levels: Before 10% COHb

exposure at levels of 30% to 70% Relative Humidity (RH):

• 400 ppm CO between 4 and 15 minutes

• 150 ppm CO between 10 and 50 minutes

• 70 ppm CO between 60 and 240 minutes

When exposed to a constant level of 30 ppm of CO, this CO alarm was tested not to go into alarm for at least for 30 days.

Audible Alarm: 85dB minimum at 10 feet. Power: Powered by 120VAC. The 9V battery

back-up provides 8 hours of standby and sounds alarm for 12 hours with fresh battery. When AC power is on, red light (LED) shines continuously. Under battery power, red light ﬂashes once a minute.

Malfunction: Horn chirps and light blinks 3 times

(in rapid succession) every minute.

Dimensions: 5.4” diameter (approx.)

4 beeps, pause, 4 beeps, pause.

• Stand-alone unit: red light (LED) ﬂashes rapidly, once per second.

• Interconnected series: red light (LED) ﬂashes rapidly, once per second on the Initiating alarm. Red light (LED) on all other alarms will not ﬂash.

Warranty: 5-year limited warranty. Standards: Underwriters Laboratories Inc.

Single and Multiple Station carbon monoxide alarms UL2034.

According to Underwriters Laboratories Inc. UL2034, Section 1-1.2: “Carbon monoxide alarms covered by these requirements are intended to respond to the presence of carbon monoxide from sources such as, but not limited to, exhaust from internal-combustion engines, abnormal operation of fuel-ﬁred appliances, and ﬁreplaces. CO alarms are intended to alarm at carbon monoxide levels below those that could cause a loss of ability to react to the dangers of Carbon Monoxide exposure.” This CO alarm monitors the air, and is designed to alarm before CO levels become life threatening. This allows you precious time to leave the house and correct the problem. This is only possible if alarms are located, installed, and maintained as described in this manual.

CHAPTER 2: Installation

WHERE TO INSTALL CO ALARMS

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.

BASEMENT

BEDROOM

KITCHEN

BEDROOM

GARAGE

In a Single-level Home:

• Install at least one CO alarm near or within each separate sleeping area.

• For added protection, install an additional CO alarm at least 20 feet (6 meters) away from the furnace or fuel burning heat source.

In a Multi-level Home:

• Install at least one CO alarm near or within each separate sleeping area.

• For added protection, install at least one CO alarm on each level of the home. If you have a basement, install that CO alarm at the top of the basement stairs.

• For added protection, install an additional CO alarm at least 20 feet (6 meters) away from the furnace or fuel burning heat source.

WARNING!

This alarm must have AC or battery power to operate. If the AC power fails, the battery back-up will power the alarm if the 9V battery is fresh and correctly installed. If AC power fails, and the battery is dead or missing, the alarm cannot operate.

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. This alarm should be at least 10 feet from a bath or shower, sauna, humidiﬁer, vaporizer, dishwasher, laundry room, utility room or other source of high humidity.

• In areas where temperature is colder than 40˚F (4˚C) or hotter than 100˚F (38˚C). These areas include unconditioned crawl spaces, unﬁnished attics, uninsulated or poorly insulated ceilings, porches, and garages.

• In turbulent air, like near ceiling fans, heat vents, air conditioners, fresh air returns, or open windows. Blowing air may prevent CO from reaching the sensors.

• In direct sunlight.

This CO alarm is designed for use inside a single-family home or apartment. It is not meant to be used in common lobbies, hallways, or basements of multi-family buildings unless working CO alarms are also installed in each family living unit. CO alarms in common areas may not be heard from inside individual family living units.

WARNING!

This CO alarm alone is not a suitable substitute for complete detection systems in places which house many people, like hotels or dormitories, unless a CO alarm is also placed in each unit.

WARNING!

DO NOT use this CO alarm in warehouses, industrial or commercial buildings, specialpurpose non-residential buildings, RVs, boats, or airplanes. This CO alarm is speciﬁcally designed for residential use, and may not provide adequate protection in nonresidential applications.

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.

Tools you will need: • Needle-nose pliers

• Standard/Flathead screwdriver. Both locking features use locking pins, molded

into the mounting bracket. Using needle nose pliers or a utility knife, remove one or both pins, depending on which locking features you use.
