HOW CAN I PROTECT MY FAMILY FROM

CO POISONING?

A CO Alarm is an excellent means of protection. It monitors the air and

sounds a loud alarm before Carbon Monoxide levels become threatening

for average, healthy adults.

A CO Alarm is not a substitute for proper maintenance of home

appliances.

To help prevent CO problems and reduce the risk of CO poisoning:

• Clean chimneys and flues yearly. Keep them free of debris,

leaves, and nests for proper air flow. Also, have a professional

check for rust and corrosion, cracks, or separations. These

conditions can prevent proper air movement and cause back-

drafting. Never "cap" or cover a chimney in any way that would

block air flow.

• Test and maintain all fuel-burning equipment annually. Many local

gas or oil companies and HVAC companies offer appliance

inspections for a nominal fee.

• Make regular visual inspections of all fuel-burning appliances.

Check appliances for excessive rust and scaling. Also check the

flame on the burner and pilot lights. The flame should be blue. A

yellow flame means fuel is not being burned completely and CO

may be present. Keep the blower door on the furnace closed.

Use vents or fans when they are available on all fuel-burning

appliances. Make sure appliances are vented to the outside. Do

not grill or barbecue indoors, or in garages or on screen porches.

• Check for exhaust backflow from CO sources. Check the draft

hood on an operating furnace for a backdraft. Look for cracks on

furnace heat exchangers.

• Check the house or garage on the other side of shared wall.

• Keep windows and doors open slightly. If you suspect that CO

is escaping into your home, open a window or a door. Opening

windows and doors can significantly decrease CO levels.

In addition, familiarize yourself with all enclosed materials. Read this

manual in its entirety, and make sure you understand what to do if your

CO Alarm sounds.

REGULATORY INFORMATION FOR

SMOKE/CO ALARMS

REGULATORY INFORMATION FOR CO ALARMS

WHAT LEVELS OF CO CAUSE AN ALARM?

Canadian Standards Association 6.19-01 requires residential CO Alarms

to sound when exposed to levels of CO and exposure times

as described below. They are measured in parts per million (ppm) of CO

over time (in minutes).

CSA 6.19-01 Required Alarm Points*:

• If the alarm is exposed to 400 ppm of CO, IT MUST ALARM

BETWEEN 4 and 15 MINUTES.

• If the alarm is exposed to 150 ppm of CO, IT MUST ALARM

BETWEEN 10 and 50 MINUTES.

• If the alarm is exposed to 70 ppm if CO, IT MUST ALARM

BETWEEN 60 and 240 MINUTES.

* Approximately 10% COHb exposure at levels of 10% to 95% Relative

Humidity (RH).

The unit is designed not to alarm when exposed to a constant level

of 30 ppm for 30 days.

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 affect

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: Canadian Standards Association 6.19-01.

According to Canadian Standards Association 6.19-01: "Carbon monox-

ide 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 opera-

tion 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 3 meters (10 feet).

REGULATORY INFORMATION FOR SMOKE ALARMS

RECOMMENDED LOCATIONS 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 4

and 38

C (100

F). Make sure no door or other obstruction could keep

smoke from reaching the Smoke Alarms.

More specifically, install Smoke Alarms:

•

On every level of your home, including finished 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 12 meters

long (40 feet), install a unit at each end.

•

At the top of the first-to-second floor stairway, and at the bottom of

the basement stairway.

Specific requirements for Smoke Alarm installation vary from state to

state and from region to region. Check with your local Fire Department

for current requirements in your area. It is recommended AC or AC/DC

units be interconnected for added protection.

AGENCY PLACEMENT RECOMMENDATIONS

NFPA 72 (National Fire Code) Chapter 11

"For your information, the National Fire Protection Association's

Standard 72, reads as follows:"

"11.5.1 One- and Two-Family Dwelling Units."

"11.5.1.1 Smoke Detection. Where required by applicable laws, codes, or

standards for the specified occupancy, approved single- and multiple -

station Smoke Alarms shall be installed as follows: (1) In all sleeping

rooms. Exception: Smoke Alarms shall not be required in sleeping rooms

in existing one- and two-family dwelling units. (2) Outside of each

separate sleeping area, in immediate vicinity of the sleeping rooms.

(3) On each level of the dwelling unit, including basements. Exception:

In existing one- and two family dwelling units, approved Smoke Alarms

"A.11.8.3 Are More Smoke Alarms Desirable? The required number

of Smoke Alarms might not provide reliable early warning protection

for those areas separated by a door from the areas protected by the

required Smoke Alarms. For this reason, it is recommended that the

householder consider the use of additional Smoke Alarms for those

areas for increased protection. The additional areas include the base-

ment, bedrooms, dining room, furnace room, utility room, and hallways

not protected by the required Smoke Alarms. The installation of Smoke

Alarms in kitchens, attics (finished or unfinished), or garages is not

normally recommended, as these locations occasionally experience

conditions that can result in improper operation."

ABOUT SMOKE ALARMS

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.

AC powered Smoke Alarms: Can be interconnected so if one unit sens-

es smoke, all units alarm. They do not operate if electricity fails.

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 qualified electrician.

ONELINK

Smoke Alarms with battery (DC) back-up: Interconnects with

all ONELINK

enabled Smoke and Smoke/CO Alarms without wires or

connectors, so when one alarm sounds, they all sound. Will operate if

electricity fails, provided the batteries are fresh and correctly installed.

Units are easy to install, and do not require professional installation.

Smoke/CO Alarms for Solar or Wind Energy users and battery backup

power systems: AC powered Smoke/CO Alarms should only be operat-

ed with true or pure sine wave inverters. Operating this 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.

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. 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.

All these Smoke Alarms are designed to provide early warning of fires 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 Smoke Alarm

to install, refer the National Fire Protection Association (NFPA) Standard

72 (National Fire Alarm Code) and NFPA 101 (Life Safety Code).
