Regulatory Information for CO Alarms (Continued)
!
IMPORTANT: CO alarms are designed to alarm before there is an immediate life threat.
Since you cannot see or smell CO, never assume it’s not present. An exposure to 100
ppm of CO for 20 minutes may not aect average, healthy adults but after 4 hours the
same level may cause headaches. An exposure to 400 ppm of CO may cause headaches
in average, healthy adults after 35 minutes, but can cause death after 2 hours.
Standards
Underwriters Laboratories Inc. Single and Multiple Station carbon monoxide alarms UL2034. According to Underwriters
Laboratories Inc. UL2034, Section 1-1.2: “Carbon monoxide alarms covered by these requirements are intended to respond to
the presence of carbon monoxide from sources such as, but not limited to, exhaust from internal-combustion engines, abnormal
operation of fuel-fired appliances, and fireplaces. CO Alarms are intended to alarm at carbon monoxide levels below those
that could cause a loss of ability to react to the dangers of Carbon Monoxide exposure.” This CO Alarm monitors the air at the
Alarm, and is designed to alarm before CO levels become life threatening. This allows you precious time to leave the house
and correct the problem. This is only possible if Alarms are located, installed, and maintained as described in this manual.
Gas Detection at Typical Temperature and Humidity Ranges
The CO Alarm is not formulated to detect CO levels below 30 ppm typically. Tested for false alarm resistance to
Methane (500 ppm), Butane (300 ppm), Heptane (500 ppm), Ethyl Acetate (200 ppm), Isopropyl Alcohol (200
ppm) and Carbon Dioxide (5000 ppm). Values measure gas and vapor concentrations in parts per million.
Audible Alarm
85 dB minimum at 10 feet (3 meters).
This carbon monoxide alarming device is designed to detect carbon monoxide gas from ANY source of combustion,
It is NOT designed to detect smoke, fire, or any other gases.
Regulatory Information for Smoke Alarms
Installing Smoke Alarms in Single-Family Residences
The National Fire Protection Association (NFPA), recommends one Smoke Alarm on every floor, in every sleeping area,
and in every bedroom. In new construction, the Smoke Alarms must be AC powered and interconnected. See “Agency
Placement Recommendations” for details. For additional coverage, it is recommended that you install a Smoke Alarm in
all rooms, halls, storage areas, finished attics, and basements, where temperatures normally remain between 40˚ F (4.4˚
C) and 100˚ F (37.8˚ C). Make sure no door or other obstruction could keep smoke from reaching the Smoke Alarms.
For your information, the National Fire Alarm and Signaling Code, NFPA 72, reads as follows:
Required Detection. Where required by applicable laws, codes, or standards for a specific type of
occupancy, approved single- and multiple-station smoke alarms shall be installed as follows:
• In all sleeping rooms and guest rooms
• Outside of each separate dwelling unit sleeping area, within 21 ft (6.4 m) of any door to a sleeping room,
the distance measured along a path of travel
