• Dangers, Warnings, and Cautions alert you to important operating instructions or to potentially hazardous situations. Pay special
attention to these items.
• This Smoke/CO Alarm is approved for use in single-family residences. It is designed for marine or RV use.NOT
• This combination Smoke/Carbon Monoxide Alarm has two separate Alarms. The CO Alarm is not designed to detect re or any
other gas. It will only indicate the presence of carbon monoxide gas at the sensor. Carbon monoxide gas may be present in other
areas. The Smoke Alarm will only indicate the presence of smoke that reaches the sensor. The Smoke Alarm is not designed to
sense gas, heat or ames.
• This Smoke/CO Alarm cannot operate without working batteries. Removing the batteries for any reason, or failing to replace the
batteries at the end of their service life, removes your protection.
• ignore any Alarm. See “If Your Smoke/CO Alarm Sounds” for more information on how to respond to an Alarm. Failure to NEVER
respond can result in injury or death.
• The Silence Features are for your convenience only and will not correct a problem. See “Using the Silence Features” for details.
Always check your home for a potential problem after any Alarm. Failure to do so can result in injury or death.
• Test this Smoke/CO Alarm once a week. If the Alarm ever fails to test correctly, have it replaced immediately! If the Alarm is not
working properly, it cannot alert you to a problem.
• This product is intended for use in ordinary indoor locations of family living units. 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 may consider using warning devices which provide
audible and visual signals for carbon monoxide concentrations under 30 ppm. For additional information on carbon monoxide and
your medical condition contact your physician.
All these Smoke Alarms are designed to provide early warning of res if located, installed and cared for as described in the user’s
manual, and if smoke reaches the Alarm. If you are unsure which type of unit to install, refer to NFPA (National Fire Protection
Association) 72 (National Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code). National Fire Protection Association,
One Batterymarch Park, Quincy, MA 02269-9101. Local building codes may also require specic units in new construction or in
different areas of the home.
Battery (DC) operated Smoke Alarms: Provide protection even when electricity fails, provided the batteries are fresh
and correctly installed. Units are easy to install, and do not require professional installation. They do not, however, provide
interconnected functionality.
AC powered Smoke Alarms: Can be interconnected so if one unit senses smoke, all units Alarm. They do not operate
AC with battery (DC) back-up: will operate if electricity fails, provided the batteries are fresh and correctly installed. AC and AC/DC
units must be installed by a qualied electrician.
Smoke Alarms for Solar or wind energy users and battery backup power systems: AC powered Smoke Alarms should only be
operated with true or pure sine wave inverters. Operating this Smoke Alarm with most battery powered UPS (uninterruptible power
supply) products or square wave or “quasi sine wave” inverters . If you are not sure about your inverter or will damage the Alarm
UPS type, please consult with the manufacturer to verify.
Smoke Alarms for the hearing impaired: Special purpose Smoke Alarms should be installed for the hearing impaired. They include
a visual Alarm and an audible Alarm horn, and meet the requirements of the Americans with Disabilities Act. These units can be
interconnected so if one unit senses smoke, all units Alarm.
Smoke Alarms are not to be used with detector guards unless the combination has been evaluated and found
suitable for that purpose.
Smoke Alarms conform to regulatory requirements, including UL217 and are designed to detect particles of
combustion. Smoke particles of varying number and size are produced in all res.
Ionization technology is generally more sensitive than photoelectric technology at detecting small particles, which tend to be
produced in greater amounts by aming res, which consume combustible materials rapidly and spread quickly. Sources of
these res may include paper burning in a wastebasket, or a grease re in the kitchen.
Photoelectric technology is generally more sensitive than ionization technology at detecting large particles, which tend to
be produced in greater amounts by smoldering res, which may smolder for hours before bursting into ame. Sources of
these res may include cigarettes burning in couches or bedding.
For maximum protection, use both types of Smoke Alarms on each level and in every bedroom of your home.
WHERE TO INSTALL THIS ALARM
Minimum coverage for Smoke Alarms, as recommended by the National Fire Protection Association (NFPA), is one Smoke Alarm
on every level, in every sleeping area, and in every bedroom (See “Regulatory Information for Smoke Alarms” for details on the
For CO Alarms, the National Fire Protection Association (NFPA) recommends that a 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.
NOTE: For added protection, install an additional Smoke/CO Alarm at least 15 feet (4.6 meters) away from the furnace or fuel burning
heat source where possible. In smaller homes or in manufactured homes where this distance cannot be maintained, install the Alarm
as far away as possible from the furnace or other fuel burning source. Installing the Alarm closer than 15 feet (4.6 meters) will not
harm the Alarm, but may increase the frequency of unwanted Alarms.
IN GENERAL, INSTALL COMBINATION SMOKE AND CARBON MONOXIDE ALARMS:
• On every level of your home, including nished attics and basements.
• Inside every bedroom, especially if people sleep with the door partly or completely closed.
• In the hall near every sleeping area. If your home has multiple sleeping areas, install a unit in each. If a hall is more than 40 feet
(12 meters) long, install a unit at each end.
• At the top of rst-to-second level stairs, and at the bottom of the basement stairs.
• For additional coverage, install Alarms in all rooms, halls, and storage areas, where temperatures normally remain between 40˚ F
and 100˚ F (4.4˚ C and 37.8˚ C).
WHERE NOT TO INSTALL THIS ALARM
FOR BEST PERFORMANCE, IT IS RECOMMENDED YOU AVOID INSTALLING SMOKE/CO ALARMS IN THESE AREAS:
• Where combustion particles are produced. Combustion particles form when something burns. Areas to avoid include poorly
ventilated kitchens, garages, and furnace rooms. Keep units at least 20 feet (6 meters) from the sources of combustion particles
(stove, furnace, water heater, space heater) if possible. In areas where a 20-foot (6-meter) distance is not possible – in modular,
mobile, or smaller homes, for example – it is recommended the Smoke Alarm be placed as far from these fuel-burning sources
as possible. The placement recommendations are intended to keep these Alarms at a reasonable distance from a fuel-burning
source, and thus reduce “unwanted” Alarms. Unwanted Alarms can occur if a Smoke Alarm is placed directly next to a fuel-
burning source. Ventilate these areas as much as possible.
• In air streams near kitchens. Air currents can draw cooking smoke into the sensing chamber of a Smoke Alarm near the kitchen.
• In very damp, humid or steamy areas, or directly near bathrooms with showers. Keep units at least 10 feet (3 meters) away from
showers, saunas, dishwashers, etc.
• Where the temperatures are regularly below 40˚ F (4.4˚ C) or above 100˚ F (37.8˚ C), including unheated buildings, outdoor rooms,
porches, or unnished attics or basements.
• In very dusty, dirty, or greasy areas. Do not install a Smoke Alarm directly over the stove or range. Keep laundry room Smoke
Alarms free of dust or lint.
• Near fresh air vents, ceiling fans, or in very drafty areas. Drafts can blow smoke away from the unit, preventing it from reaching
• In insect infested areas. Insects can clog openings to the sensing chamber and cause unwanted Alarms.
• Less than 12 inches (305mm) away from uorescent lights. Electrical “noise” can interfere with the sensor.
• In “dead air” spaces. “Dead air” spaces may prevent smoke from reaching the Smoke Alarm.
“Dead air” spaces may prevent smoke from reaching the Smoke Alarm. To avoid dead air spaces, follow the installation
On ceilings, install Smoke Alarms as close to the center of the ceiling as possible. If this is not possible, install the Smoke Alarm at
least 4 inches (102 mm) from the wall or corner.
For wall mounting (if allowed by building codes), the top edge of Smoke Alarms should be placed between 4 inches (102 mm) and
12 inches (305 mm) from the wall/ceiling line, below typical “dead air” spaces.
On a peaked, gabled, or cathedral ceiling, install the rst Smoke Alarm within 3 feet (0.9 meters) of the peak of the ceiling,
measured horizontally. Additional Smoke Alarms may be required depending on the length, angle, etc. of the ceiling’s slope. Refer to
NFPA 72 for details on requirements for sloped or peaked ceilings.
