All connections should be made by a professional technician, and all wiring should comply with articles 210 and 300.3 (B) of the U.S. National Electrical Code ANSI/NFPA 70, NFPA 72, and/or any other codes having jurisdiction in your area.

Location in Your Home

In accordance with NFPA recommendations, it is recommended to install an X-Sense smoke and carbon monoxide alarm.On every level of your home, including finished attics and basements. Inside every bedroom or adjacent hallway to every sleeping area. If a room or hallway is longer than 40 feet 12 m install a device at each end.  In every room containing a fuel-burning appliance. In all rooms, hallways, and storage areas where the temperature is usually between 40-l00’F 4.4-37S(C)

Placement on a Wall or Ceiling

It is recommended that you install an alarm on the ceiling so that it can detect the first traces of smoke when smoke rises. However, regardless of where you install it, ensure that nothing can prevent smoke or CO from reaching the alarm. If you install the device on the ceiling, center it in the room, as smoke spreads horizontally after rising to the ceiling. Make sure it is at least 20 inches 50 cm away from the wall. If an alarm is installed onto a wall, keep 4-12 inches 10-30 cm below the ceiling.If you install the alarm on a sloped ceiling, place it between 4 inches 10 cm and 35 inches 90 cm from the peak. Keep the device at least 5 feet (1.5 m) from potential smoke or fume sources such as stoves, furnaces, water heaters, and space heaters.

Mobile Home Installation

In mobile homes or older houses, extreme heat and cold can spread from the outside to the inside due to poorly insulated walls and roofing. This may create a thermal barrier that can prevent smoke from reaching the alarm. In this situation, install the device on an inside wall with the top edge of the device at a minimum of 4 inches (10 cm) and a maximum of 12 inches 30 cm below the ceiling. If you are unsure about the insulation quality of your home, install the alarm on an inside wall near the bedrooms. Test the alarm before each trip and at least once a week during use.

Locations to Avoid

Improper location can have a negative impact on device performance and may cause false alarms. To promote accurate detection and full protection of your home, do not install this combination smoke and carbon monoxide alarm.In a garage or any area that is dusty, dirty, or greasy. In bathrooms, kitchens, garages, attics, in unheated areas, or near recessed ceiling areas, ceiling fans, furnaces, or furnace vents. Keep the alarm at least 3 feet 0.9 m away horizontally from bathroom doors. Within 5 feet 1.5 m of smoke sources, such as a stove. In extremely humid environments. Keep the unit at least 10 feet 3 m away from baths, saunas, humidifiers, vaporizers, dishwashers, laundry rooms, or other sources of extreme humidity. In turbulent air, such as near ceiling fans, heat vents, air conditioner vents, or open windows, as excessive airfiow may prevent CO from reaching the sensors. Under direct sunlight. In dead air spaces that may prevent smoke from reaching the device. Near cooking appliances, dusty areas, showers, or any areas where the temperature drops below 40F (4.4C) or rises above 1 00 F 37.8  C.

Safety

General Safety Information

This alarm is designed to detect carbon monoxide from combustion sources and is only approved for home use.  This alarm is not to be used with detector guards unless the combination has been evaluated and found suitable for that purpose. Constant exposure to high or low humidity levels can reduce battery life and impair performance.

CAUTION
This smoke & carbon monoxide alarm has two separate sensors that work independently of each other. The carbon monoxide sensor will not detect fire or any other gases, but alerts you to the presence of carbon monoxide gas at the sensor. Carbon monoxide gas may also be present in other areas. The smoke sensor will only indicate the presence of smoke at the sensor. The smoke sensor is not designed to detect gas, heat, or fiames.

WARNING

• Never ignore any alarm, as this may result in serious injury or even death.

• The silence function will not remove any sources of danger.

• It is merely for convenience.

• Check your home safety for any potential dangers when an alarm is triggered.

• Failure to do so may result in serious injuries or even death.

• Test this smoke/CO alarm once a week.

• If the alarm ever fails to test correctly, replace it immediately! If the alarm is not working properly it will not alert you to a problem.
  This product is intended for use in indoor households.

• It is not designed to measure CO levels in compliance with occupational safety and health administration (OSHA) commercial or industrial standards. Individuals with medical conditions that may make them more sensitive to carbon monoxide should consider using devices that provide audible and visual signals for carbon monoxide concentrations under 30 ppm.

• For additional information on carbon monoxide or related medical conditions, contact your physician.

• The replacement date that appears on the device is the date beyond which the device may no longer detect carbon monoxide accurately, at which point the device should be replaced.

• This device is designed to protect individuals from the acute effects of carbon monoxide exposure. It may not fully safeguard individuals with specific medical conditions. If you have any concerns, consult a medical practitioner.

• Do not disconnect power from an AC powered unit to silence a false alarm. Doing so will disable the unit and remove your protection.

Smoke Alarm

Limitations of Smoke Alarms

Alarms reduce deaths resulting from home fires worldwide. However, smoke alarms will only work when properly located, installed, and maintained, and only if smoke reaches the alarms.

• Smoke alarms may not wake up all individuals.
• Make sure you create an escape plan, and you practice fire drills with all family members.
• Smoke alarms cannot work without power.
• If they are battery powered, they cannot work if the batteries are missing, dead, or disconnected.
• If the alarm is wired, it cannot work during extended power outages, as the backup battery will die.
• X-Sense units will notify you in advance when batteries are running low so that you have time to replace them.
• Smoke will not be able to reach the smoke sensor while the dust cover is in place.
• The dust cover must be removed.
• Smoke alarms cannot detect fires if the smoke does not reach the alarm.
• For example, if a door is closed, smoke may not reach the smoke alarm.
• This is why you should have a smoke alarm in every bedroom and in hallways, as bedroom doors are often closed at night.
• Smoke alarms may not be heard. Although the smoke alarm is equipped with a loud buzzer measuring at 85 dB, it may not be heard if 1) people have consumed alcohol or drugs, the alarm is drowned out by noise from a stereo, TV, traffic, air conditioner, or other appliances, 3) residents are hearing impaired or have high-frequency hearing loss. Special smoke alarms should be installed for the hearing impaired.
• This smoke alarm alone is not a suitable substitute for complete fire detection systems in places that house lots of people, such as fiats, condominiums, hotels, guest houses, residence halls, hospitals, long-term health care facilities, nursing homes, daycare facilities, or group homes of any kind.
• It is also not a suitable substitute for a complete fire detection system in warehouses, industrial facilities, commercial buildings, and special purpose non residential buildings which require special fire detection and alarm systems.
• Depending on the building codes in your area, this smoke alarm may be used to provide additional protection in these facilities.

CO Alarm

CO Alarm Level

This alarm will sound an alarm when the following CO concentrations are detected within the time periods listed:

• 70 ppm for 60-240 minutes
• 150 ppm for 10-60 minutes
• 400 ppm for 4-15 minutes

When the CO concentration reaches the alarm level, this alarm will emit four short beeps, and the LED indicator will fiash red every 5.8 seconds.

CO Concentration and Symptoms

The table below shows the effects that different levels of CO can have on the body

Risk to life after over three hoursof exposure.
800| Severe headaches, convulsions, vital organ failures. Death possible within two or three hours.

Limitations of CO Alarms

The alarm may not wake up everyone in the house. If children or other people do not quickly wake up, or if you have infants or family members with limited mobility, make sure they are assisted during an emergency. This alarm will not detect CO that does not reach the sensor. Doors or other obstructions may prevent CO from reaching the alarm, so make sure there is at least one alarm installed in sleeping areas, where the door is often closed at night. CO alarms may not sense CO on another level of the house. For example, a CO alarm on the second level may not sense CO in the basement. Therefore, placing CO alarms on each level of the house is recommended.CO alarms may not always be heard. The alarm noise level is over 85 dB at a distance of 10 feet (3 m). However, if the CO alarm is installed outside the bedroom, it may not wake up a sound sleeper or someone who has recently used drugs or has been drinking alcohol. This is especially true if the door is closed or only partially open. Even people that are already awake may not hear the alarm if the sound is drowned out by distance or closed doors. Noise from traffic, stereos, radios, televisions, air conditioners,
or other appliances can also prevent people from hearing the alarm. This CO alarm is not intended for people who are hearing impaired. CO alarms are not a substitute for life insurance. Though these CO alarms warn you of increasing CO levels, we do not warrant or imply in any way that they will protect anyone 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 stringent testing and are designed to be as reliable as possible, any of these parts could fail at any time. Therefore, it is strongly recommended that you 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 the sensor. They may not give an early warning of rising CO levels if the CO is coming from a remote part of the house or is far away from the CO alarm.

Electrical Shock Hazard
Turn off power to the area where you want to install this unit at the circuit breaker or fuse box before installation. Failure to turn off power before installation may result in serious electrical shock, injury, or death. Do not restore power until all alarms are completely installed. Doing so may result in serious electrical shock, injury, or death. Turn off power to the area where the alarm is installed before removing it from the mounting bracket. Failure to turn off power first may result in serious electrical shock, injury, or death. If any unit in the series does not alarm, turn off power and re-check all connections. After that, if it does not alarm yet, replace it immediately.  Attempting to disconnect the power connector from the unit while the power is on may result in electrical shock, serious injury, or death. Failure to meet any of the above requirements could damage the units and cause them to malfunction. The alarm cannot be operated from power derived from a square wave, modified square wave, or modified sine wave inverter. These types of inverters are sometimes used to supply power to structures in off grid installations, such as solar or wind-derived power sources. These power sources produce high peak voltages that can damage the alarm. Improper wiring of the power connector will cause damage to the alarm and may lead to non functioning alarm. Test the alarm to ensure proper installation.
