INTRODUCTION FIRE SAFETY TIPS

Follow safety rules and prevent hazardous situations:

  1. Use smoking materials properly. Never smoke in bed.
  2. Keep matches or lighters away from children;
  3. Store flammable materials in proper containers;
  4. Keep electrical appliances in good condition and don’t overload electrical circuits;
  5. Keep stoves, barbecue grills, fireplaces, and chimneys grease- and debris-free;
  6. Never leave anything cooking on the stove unattended;
  7. Keep portable heaters and open flames, like candles, away from flammable materials;
  8. Don’t let rubbish accumulate. Keep alarms clean, and test them weekly. Replace alarms immediately if they are not working properly. Smoke Alarms that do not work cannot alert you to a fire.

Cautions

  • This combination Smoke/Carbon Monoxide Alarm has two separate alarms. Carbon monoxide gas may be present in other areas. The Smoke Alarm will only indicate the presence of smoke that reaches the sensor.
Warning
  • This Smoke/CO Alarm cannot operate without working batteries. Removing the batteries for any reason, or failing to replace the batteries at the end of their service life, removes your protection.
  • NEVER ignore any alarm. See “If Your Smoke/CO Alarm Sounds” for more information on how to respond to an alarm. Failure to respond can result in injury or death.
  • The Silence Features are for your convenience only and will not correct a problem. See “Using the Silence Features” for details. Always check your home for a potential problem after any alarm. If the Alarm ever fails to test correctly, have it replaced immediately! If the Alarm is not working properly, it cannot alert you to a problem.
  • Individuals with medical conditions that may make them more sensitive to carbon monoxide may consider using warning devices that provide audible and visual signals for carbon monoxide concentrations under 30 ppm. For additional information on carbon monoxide and your medical condition contact your physician.

INSTALLATION

WHERE TO INSTALL THIS ALARM
For Gas Alarms, mounting depends on the type of explosive gas you intend to detect. If you do not live in a rural area you are likely to be a user of natural gas. Natural gas is a fossil fuel consisting mainly of Methane.

Improper location can affect the sensitive electronic components in this Alarm.

Recommended Placement

First Alert GCO1 Explosive Gas & Carbon Monoxide Alarm Manual fig 1

To avoid causing damage to the unit, to provide optimum protection, and to prevent unnecessary alarms, Do NOT locate this Alarm:

  • In garages, kitchens, crawl spaces, and unfinished attics. Avoid extremely dusty, dirty, or greasy areas.
  • In the garage, vehicle exhaust can contain some carbon monoxide.
  • Within hours of starting a vehicle and backing it out of the garage, the levels present over time can activate the Alarm and become a nuisance.
    Continued
  • In the kitchen, some gas appliances can emit a short burst of CO or gas upon start-up. This is normal.
  • In extremely humid areas.
  • In direct sunlight.
BEFORE YOU BEGIN THE INSTALLATION

If you are not certain which type of gas you are using in your home, please read about natural gas and propane in “Where to Install this Alarm”.

Find the pair of self-adhesive labels included with this Gas/CO Alarm.

  • On each label write in the phone number of your emergency responder (like 911) and a qualified appliance technician.
  • Place one label near the Gas/CO Alarm, and the other label in the “fresh air” location you plan to go if the alarm sounds.

HOW TO INSTALL THIS GAS/CO ALARM

IMPORTANT!
Tools you will need: Screwdriver, drill.

  • Determine the best location for your Gas/CO Alarm.

HOW YOUR ALARM WORKS

First Alert GCO1 Explosive Gas & Carbon Monoxide Alarm Manual fig 2

  1. Test/Silence Button: Press and hold to activate the test, or to silence the alarm.
  2. POWER Light (GREEN)
  3. Display
  4. (Behind the Cover) Alarm Horn: 85 dB audible alarm for test, alarm, and unit malfunction warning.
  5. Display Button: Press to recall the highest CO level recorded
  6. Battery Compartment

USING THE SILENCE FEATURES
NEVER disconnect the power to your Alarm to silence the horn—use the Silence Feature. Disconnecting the Alarm removes your protection!

When the GAS Alarm is silenced…
If the gas has not cleared within the silence period, the unit will go back into alarm. The CO Alarm will remain silent for up to 4 minutes.

SILENCING THE LOW BATTERY WARNING

This Silence Feature can temporarily quiet the low battery warning “chirp” for up to 8 hours if AC power is present. After 8 hours, the low battery “chirp” will resume.

USING THE PEAK CO MEMORY
The CO Memory Feature lets you check the highest level of CO recorded.

  1. Automatically resets after 24 hours.
  2. Remove all power; unplug the Alarm and remove the battery.

REGULAR MAINTENANCE

  • Relocate the unit if it sounds like frequent unwanted alarms. You should replace the battery immediately to continue your protection. This Alarm must have AC or battery power to operate. If AC power fails, and the battery is dead or missing, the Alarm cannot operate.

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, 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).

First Alert SCO5 Combination & Carbon Monoxide Alarm Guide fig 4

    • Wind direction and/or velocity, including high, gusty winds. Heavy air in the vent pipes (cold/humid air with extended periods between cycles).
    • Negative pressure differential resulting from the use of exhaust fans.
    • Vent pipe connections vibrate loose from clothes dryers, furnaces, or water heaters.
    • Obstructions in or unconventional vent pipe designs that can amplify the above situations.
  1. Extended operation of unvented fuel-burning devices (range, oven, fireplace).
  2. Temperature inversions, which can trap exhaust close to the ground.
  3. Car idling in an open or closed attached garage or near a home.
