manual abstract
Gently push the unit all the way into the outlet, and make sure the outlet is not controlled by a dimmer or switch. Check the battery. Why does the word “bat” keep flashing on the display? (You will also hear a “chirp” once a minute.) The battery is weak or missing. Install a new battery immediately. Why is the word “bat” continuously displayed? The unit is operating on battery back-up. Why does the Alarm sound three rapid “chirps” every minute (MALFUNCTION SIGNAL)? Make sure the battery is installed correctly. If the display reads “Err,” replace the CO Alarm immediately. Units under warranty can be returned to the manufacturer for replacement. See Warranty for details. Why does the alarm sound again about 4 minutes after I used the Silence Feature? CO levels still indicate a potentially dangerous situation. Refer to “If Your CO Alarm Sounds” for details on how to respond to an alarm. If anyone is feeling ill, EVACUATE your home immediately. Why does the CO Alarm sound frequently, but no high levels of CO are found in an investigation? The CO Alarm may be improperly located. Try relocating your alarm. (Refer to “Where to Install CO Alarms.”) If frequent alarms continue, have home rechecked for potential CO problems. You may be experiencing an intermittent CO problem. 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 detectors 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 will not work without power. This CO Alarm requires a continuous supply of AC power. Plug into an unswitched 120V AC outlet only. The battery back-up is for emergency use only! CO Alarms for Solar or Wind Energy users and battery backup power systems: AC powered CO Alarms should only be operated with true or pure sine wave inverters. Operating this CO Alarm with most battery-powered UPS (uninterruptible power supply) products or square wave or “quasi sine wave” inverters will damage the Alarm. If you are not sure about your inverter or UPS type, please consult with the manufacturer to verify. 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 UL standards of 85 dB at 10 feet (3 meters). 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, BRK Brands, Inc. 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. BRK Brands, Inc. ("BRK") the maker of First Alert® brand products, warrants that for a period of 5 years from the date of purch...
