HOW Your Alarm Works

TEST THE ALARM

1.Make sure the Alarm is receiving AC power. Under normal operation, the Green indicator light will shine continuously. If the Green power indicator light does not light, recheck connections. If connections are correct and the Green power indicator still does not light, the unit should be replaced immediately.

2.Press and hold the test button until the alarm sounds. You will hear the signal that indicates the presence of explosive gas followed by the signal for carbon monoxide.

When testing the Alarm, have someone else check that the Alarm can be heard easily from the sleeping areas. The unit should be located where it can wake you if it alarms at night.

WHAT TO DO IF EXPLOSIVE GAS IS DETECTED

If you hear the alarm horn sound one beep per second, gas has been detected. The word GAS will be displayed.

Evacuate everyone from the building.

1.Leave the house immediately, opening doors and windows as you leave.

2.Do not use your telephone or appliances. Do not turn any light switches off or on. Any spark or flame could ignite the gas.

3.Call 911 and your gas company from a phone that is away from your home.

4.Do not re-enter the area until the source of the leak is found and corrected.

•If the unit alarms and you are not testing the unit, it is warning you of a potentially dangerous situation that requires your immediate attention. NEVER ignore any alarm. Ignoring the alarm may result in injury or death.

•Never disconnect the power to quiet an unwanted alarm. Disconnecting the power disables the Alarm. This will remove your protection.

Alarms have various limitations. See "General Limitations of Gas/CO Alarms" for details.

USING THE SILENCE FEATURE

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

•The Silence Feature is intended to temporarily silence the horn while you identify and correct the problem.

•To use the Silence Feature, press the Test/Silence button until the horn is silent.

•If the Test/Silence button is pressed while the Alarm is in the silence mode, the alarm will start sounding again.

WHEN THE GAS ALARM IS SILENCED...

IF YOUR GAS/CO ALARM SOUNDS

WHAT TO DO IF CARBON MONOXIDE IS DETECTED

Actuation of your CO Alarm indicates the presence of carbon monoxide (CO) which can kill you. In other words, when your CO Alarm sounds, you must not ignore it!

IF THE CO ALARM SOUNDS:

1.Operate the Test/Silence button.

2.Call your emergency services, fire department or 911. Write down the number of your local emergency service here:

_______________________________________________________________

3.Immediately move to fresh air—outdoors or by an open door or window. Do a head count to check that all persons are accounted for. Do not re- enter the premises, or move away from the open door or window until the emergency services responder has arrived, the premises have been aired out, and your CO Alarm remains in its normal condition.

4.After following steps 1-3, if your CO Alarm reactivates within a 24-hour period, repeat steps 1-3 and call a qualified appliance technician to investigate for sources of CO from fuel-burning equipment and appliances, and inspect for proper operation of this equipment. If problems are identi- fied during this inspection have the equipment serviced immediately. Note any combustion equipment not inspected by the technician, and consult the manufacturers’ instructions, or contact the manufacturers directly, for more information about CO safety and this equipment. Make sure that motor vehicles are not, and have not, been operating in an attached garage or adjacent to the residence. Write down the number of a qualified appliance technician here:

_______________________________________________________________

The Alarm will remain silent for approximately 2 minutes and then return to normal operation. If the gas has not cleared within the silence period, the unit will go back into alarm.

WHEN THE CO ALARM IS SILENCED...

The CO Alarm will remain silent for up to 4 minutes. While the Alarm is silenced, it will continue to monitor the air for CO. After 4 minutes, if CO levels remain potentially dangerous the horn will start sounding again.

The Silence Feature is intended to temporarily silence the Alarm horn. It will not correct a CO or gas problem.

USING THE REMOTE CONTROL TEST/SILENCE FEATURE

Using the VOLUME or CHANNEL buttons on most remote controls, you can test or silence this gas/CO Alarm from up to 12 feet (3.6 meters) away.

To Test or Silence the Alarm:

1. Make sure you have a clear path between you and the Alarm, free of any obstructions.

2. Point the remote at the front of the Alarm.

3. Press the VOLUME or CHANNEL button for at least 5 seconds.

If the Alarm does not respond to your remote control:

• You may be standing too far away.

•Your remote may not be compatible.

•You did not hold the button on your remote for at least 5 seconds.

•AC power must be present to Silence the low battery chirp.

Model GCO1 specifications

The First Alert Model GCO1 is a high-performing carbon monoxide detector that provides essential safety features for homes and businesses. Designed to ensure your well-being, this model is equipped with advanced technologies and characteristics that make it an excellent choice for early detection of harmful CO gas.

One of the primary features of the GCO1 is its electrochemical sensor. This sensor technology is known for its quick response time and accuracy in detecting low levels of carbon monoxide. Traditional detectors may not pick up on minor CO levels until it’s too late, but the GCO1 can alert users earlier, potentially preventing dangerous health issues.

The device is designed with an easy-to-read digital display that continuously shows the level of carbon monoxide present in the air. This feature allows users to monitor CO levels in real-time, providing peace of mind and ensuring prompt action if necessary. The GCO1 also includes a loud 85-decibel alarm that goes off when dangerous levels of carbon monoxide are detected, ensuring that even those with hearing impairments or who are asleep will be alerted.

A significant advantage of the First Alert GCO1 is its battery backup system. In the event of a power outage, the unit continues to function, ensuring uninterrupted protection. The GCO1 typically operates on a 9-volt battery, which is easily replaceable, adding to its user-friendly design. Users can quickly change the battery when prompted by the low battery warning signal.

Moreover, the GCO1 highlights a user-friendly interface with a simple test/silence button. This allows for easy testing of the device to ensure it is working properly while also enabling users to silence false alarms, such as those caused by cooking or other household activities.

The compact design of the First Alert GCO1 allows it to fit seamlessly in any room, whether mounted on a wall or placed on a tabletop. With an attractive finish, it suits various interior decors without standing out as an eyesore.

In summary, the First Alert Model GCO1 combines sophisticated technology with user-centric features, making it a reliable carbon monoxide detector. Its advanced electrochemical sensor, digital display, battery backup, and compact design ensure that families and facilities stay protected from the silent threat of carbon monoxide, providing a significant layer of safety in everyday life.
