Mild Exposure: 

Slight headache, nausea, vomiting, fatigue (often described as “flu-like” symptoms)

 

Medium Exposure:

 Severe throbbing headache, drowsiness, confusion, fast heart rate.   

Extreme Exposure:

 Unconsciousness, convulsions, cardio respiratory failure, death.   

Many cases of reported CARBON MONOXIDE POISONING indicate that while victims are aware they are not well. They become 

so disoriented they are unable to save themselves by either the building or calling for assistance. Yong children and household pets are 

typically the first affected. 

 

5. GENERAL LIMITATIONS OF CO ALARMS 

This CO Alarm is intended for residential use. It is not intended for use in industrial applications where Occupational Safety 

and Health Administration (OSHA) requirements for Carbon Monoxide Alarms must be met. 

CO alarms may not waken all individuals.

 If children or others do not readily waken to the sound of the CO alarm, or if there are 

infants or family members with mobility limitations, make sure that someone is assigned to assist them in the event of an emergency. 

CO Alarms cannot work without power.

 Battery operated units cannot work if the batteries are missing, disconnected or dead, if the 

wrong type of batteries are used, or if the batteries are not installed correctly. 

This CO Alarm will not sense carbon monoxide that does not reach the sensor.

 This CO Alarm will only sense CO at the sensor. 

CO may be present in other areas. Doors or other obstructions may affect the rate at which CO reaches the CO Alarm. For this reason, 

if bedroom doors are usually closed at night, we recommend you install a CO Alarm in each bedroom and in the hallway between 

them. 

CO Alarms may not sense CO on another level of the home.

 For example, a CO Alarm on the second level, near the bedrooms, 

may not sense CO in the basement. For this reason, one CO Alarm may not give adequate warning. Complete coverage is 

recommended. Place CO Alarms on each level of the home. 

CO Alarms may not be heard.

 The alarm horn loudness meets or exceeds current EN standards of 85 dB at 1 meter. However, if the 

CO Alarm is installed outside the bedroom, it may not wake up a sound sleeper or one who has recently used drugs or has been 

drinking alcoholic beverages. This is especially true if the door is closed or only partly open. Even persons who are awake may not 

hear the alarm horn if the sound is blocked by distance or closed doors. Noise from traffic, stereo, radio, television, air conditioner, or 

other appliances may also prevent alert persons from hearing the alarm horn. This CO Alarm is not intended for people who are 

hearing impaired. 

CO Alarms are not a substitute for a smoke alarm.

 Although fire is a source of carbon monoxide, this CO Alarm does not sense 

smoke or fire. This CO Alarm senses CO that may be escaping unnoticed from malfunctioning furnaces, appliances, or other sources. 

Early warning of fire requires the installation of smoke alarms. 

CO Alarms are not a substitute for life insurance.

 Though these CO Alarms warn against increasing CO levels, we does not 

warrant or imply in any way that they will protect lives from CO poisoning. Homeowners and renters must still insure their lives. 

CO Alarms have a limited life.

 Although the CO Alarm and all of its parts have passed many stringent tests and are designed to be as 

reliable as possible, any of these parts could fail at any time. Therefore, you must test your CO Alarm weekly. 

CO Alarms are not foolproof.

 Like all other electronic devices, CO Alarms have limitations. They can only detect CO that reaches 

their sensors. They may not give early warning to rising CO levels if the CO is coming from a remote part of the home, away from the 

CO Alarm. 

INSTALLATION 

WHERE TO INSTALL THIS ALARM 

CO Alarm should be centrally located outside of each separate sleeping area in the immediate vicinity of the bedrooms. For added 

protection, install additional CO Alarms in each separate bedroom, and on every level of your home.
