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 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.

WARNING!

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).

This Carbon Monoxide Alarm features a permanently installed sensor, three colored 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 LIGHTS AND ALARM TONES MEAN

During Power Up (or After Power Outage)

During an Alarm

Green light ON. Yellow & red lights OFF. Horn “chirps” once.

During Normal Operation

Green light ON. Yellow & red lights OFF. Horn silent.

During Normal Test

All three lights ﬂash brieﬂy. Horn pattern repeats twice: 4 beeps, then a pause, 4 beeps, then a pause.

Green light ON. Yellow light OFF. Red light FLASHES. Repeating horn pattern: 4 beeps, then a pause, 4 beeps, then a pause.

During Alarm Malfunction

Green light ON. Yellow light ON. Red light FLASHES. Horn “chirps” about twice a minute.

Using the Silence Feature in Alarm

Green light ON. Yellow light OFF. Red light FLASHES. Horn silent for 4 minutes. Refer to Chapter 3 for details on the Silence feature.

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

The unit is designed not to alarm when exposed to a constant level of 30 ppm for 30 days.

Audible Alarm: 85dB minimum at 10 feet Power: Powered by 120V AC. When power is

on, green light shines continuously.

Malfunction: Yellow light shines continuously.

Red light ﬂashes. Horn chirps twice a minute.

Dimensions: 5.83" x 3.32" x 1.6" (Approx.) Supply Voltage: 120V AC 60Hz

.085A Standby .087A Alarm

The CO Alarm is not

During Alarm: CO Alarm horn sounds while the

red light ﬂashes rapidly.

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.
