If Your CO Alarm Sounds

HOW TO INSTALL YOUR CO ALARM

Read “Where To Install CO Alarms” before starting.

Before you start installation, find the pair of self-adhesive labels included with this CO Alarm. On each label write in the phone number of your emergency responder (like 911) and a qualified appliance techni- cian. Place one label near the CO Alarm, and the other label in the “fresh air” location you plan to go if the alarm sounds.

Quick reference:

•Install the two (2) AA batteries to activate the battery back-up.

•Plug the Alarm into a standard 120V unswitched outlet.

•Test the CO Alarm.

ACTIVATE THE BATTERY BACK-UP

1.Open the battery compartment on the front of the Alarm.

2. Install both AA batteries inside the battery compartment as indicated. Make sure the “+” and “–” ends of each battery are aligned properly.

3. Close the battery compartment completely.

The battery back-up is designed to provide emergency power to the CO Alarm for at least 7 days. Actual back-up time depends on the strength (freshness) of the battery. The battery back-up will not work unless a good battery is properly installed.

PLUG THE ALARM INTO AN OUTLET

1.Plug the unit into a standard UNSWITCHED 120V AC outlet.

The unit should be located

where it can wake you if it AC Plug alarms at night.

2.Make sure the POWER/ALARM light shines continuously when you plug it in.

3.Test by pressing the Test/Silence button firmly until the unit sounds: four loud beeps, pause, 4 beeps. During testing, the POWER/ ALARM light will flash rapidly. This is normal.

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 ALARM SIGNAL 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 identified 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:

“ALARM-MOVE TO FRESH AIR”

If you hear the alarm horn and the red light is flashing,

move everyone to a source of fresh air.

DO NOT unplug the CO Alarm!

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

USING THE SILENCE FEATURE

•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.

•NEVER remove the batteries from your CO Alarm to silence the horn. Use the silence feature. Removing the batteries removes your protection! See “If Your CO Alarm Sounds” for details on responding to an alarm.

The Silence Feature is intended to temporarily silence your CO Alarm’s alarm horn while you correct the problem—it will not correct a CO prob- lem. While the alarm is silenced it will continue to monitor the air for CO.

When CO reaches alarm levels the alarm will sound— repeating horn pattern: 4 beeps, a pause, 4 beeps, etc. Press and hold the Test/Silence button until the horn is silent. The initial Silence cycle will last approxi- mately 4 minutes.

NOTE: After initial 4-minute Silence cycle, the CO Alarm re-evaluates present CO levels and responds accordingly. If CO levels remain poten- tially dangerous—or start rising higher—the horn will start sounding again.

SILENCING THE LOW BATTERY WARNING

Pressing the silence button can stop the low battery “chirp” for up to 8 hours; do not remove the battery or unplug the Alarm, unless changing the battery. Activation of low battery silence is acknowledged with an LED 1-second blink with AC, or a double-flash with DC.

Once the low battery warning “chirp” silence feature is activated, the unit continues to flash the red light once a minute for 8 hours. After 8 hours, the low battery “chirp” will resume. Replace the batteries as soon as possible.

To deactivate this feature: Press the Test/Silence button again. The unit will go into Test Mode and the low battery warning will resume.

If you cannot silence the low battery warning, replace the batteries immediately.

While the detector is silenced:

Is silent for only 4 minutes,	CO levels are still potentially
then starts sounding loudly—	dangerous.
4 beeps, pause,

If the CO Alarm...	This means...
