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.

Reliable Protection, Maximum Convenience!

•Just install the battery, plug the alarm into a regular outlet, test, and it’s ready to go!

•Battery back-up keeps alarm working if electricity fails.

•Test or silence the alarm with a single push of most house- hold remote controls.

•Memory stores highest levels of CO detected. Easy to dis- play, easy to clear!

120V AC ~ 60 Hz 0.09A

• This CO Alarm is approved for use in single-family residences.

It is NOT designed for marine or RV 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.

• This CO Alarm should receive continuous 120VAC, 60 Hz, pure sine

wave electrical power. (The battery is meant for emergency back-up

only). Do not use in an extension cord or outlet controlled by a dim-

mer or switch. In order for the emergency battery back-up to work, a

working (fresh) battery must be properly installed.

• NEVER ignore your Carbon Monoxide Alarm if it alarms. Refer to

“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) commer-

cial or industrial standards. Individuals with medical conditions that

may make them more sensitive to carbon monoxide may consider

using warning devices which provide audible and visual signals for

carbon monoxide concentrations under 30 ppm. For additional infor-

mation on carbon monoxide and your medical condition contact your

physician.

HOW YOUR CO ALARM WORKS

GENERAL INFORMATION

Leave your CO Alarm plugged in year-round. 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, the unit 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 Alarm sounds 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 CO Alarm features a permanently installed sensor, an indicator light, 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, replace it immediately.

FCD4 specifications

The First Alert FCD4 is a highly regarded combination smoke and carbon monoxide detector, designed to enhance home safety through advanced technology and innovative features. This unit is particularly notable for its dual functionality, providing reliable detection for both smoke and carbon monoxide—two of the most significant threats to home safety.

One of the main features of the First Alert FCD4 is its photoelectric smoke detection technology. This system is designed to minimize false alarms often triggered by cooking smoke or shower steam, making it a suitable choice for kitchens and bathrooms. Photoelectric sensors detect larger smoke particles produced by smoldering fires, offering a fast response to potential hazards while reducing unnecessary disturbances.

The FCD4 is equipped with an electrochemical CO sensor, which is the most effective technology for detecting carbon monoxide. This feature allows the device to monitor CO levels continuously, providing alerts before harmful levels are reached. The combination of smoke and CO detection in one unit simplifies installation and maximizes safety by ensuring that homeowners are alerted to multiple dangers with a single device.

Another characteristic of the First Alert FCD4 is its battery operation, which enhances its reliability. The unit comes with a 10-year battery life, eliminating the need for frequent battery changes. Additionally, it features a convenient battery lockout system that helps prevent the device from being accidentally powered on without a battery in place, enhancing safety during installation.

A notable convenience feature of the FCD4 is its easy-to-read LED display that indicates the status of the unit, including whether it is in alarm mode or when the battery needs to be replaced. The device also includes an easy-access testing and silencing button, which allows homeowners to test its functionality quickly and silence alarms without removing the batteries.

The First Alert FCD4 meets safety standards set by Underwriters Laboratories, ensuring it has been rigorously tested for reliability and effectiveness. It stands out as a comprehensive safety solution, combining modern technology with user-friendly features and a commitment to protecting families from the dangers of smoke and carbon monoxide.
