INSTALLATION

WHERE TO INSTALL THIS ALARM

For Gas Alarms, mounting depends on the type of explosive gas you intend to detect.

Natural Gas (methane) is typically supplied through a main utility line connected to your home. If you do not live in a rural area you are likely to be a user of natural gas.Natural gas is a fossil fuel consisting mainly of Methane.Methane is much lighter than air and will rise rapidly in air. If you are a user of natural gas, the Alarm should be mounte d between 6 and 12 inches (152mm and 305 mm) away from the ceiling (using cord feature) to ensure the earliest opportunity to detect a leak.

Propane is typically supplied to homes by delivery truck in liquid form and stored near the home in propane tanks. Propane is used by homes in rural areas that do not have natural gas service. Since propane is the most commonly used Liquefied Petroleum Gas (LPG), often used synonymously.Unlike natural gas, propane is heavier than air and will collect at lower levels. If you are a user of propane, the Alarm should be mounted near the floor (using the direct plug-in feature) to ensure the earliest opportunity to detect a leak.

Both propane and natural gas are colorless and odorless. For safety reasons, an ordorant (Mercaptan) is added so that any leak can be detect-

WHERE THIS ALARM SHOULD NOT BE INSTALLED

o avoid causing damage to the unit , to provide optimum protection, and

T to prevent unnecessary alarms, Do NOTlocate this Alarm:

• In garages,kitchens,crawl spaces and unfinished attics. Avoid extremely usty, dirty or greasy areas.Installation in these areas could lead to

d nuisance alarms,may expose the sensor to substances that could damage or contaminate it, or the Alarm may not be heard by persons in other areas

f the home,especially if they are sleeping.

• In the garage,vehicle exhaust can contain some carbon monoxide. These

levels are higher whe n the engine is first started.Within hours of starting a

ehicle and backing it out of the garage, the levels present over time can

v activate the Alarm and be come a nuisance.

• In the kitchen, some gas appliances can emit a short burst of CO or gas

pon start-up.This is normal. If your Explosive Gas/CO Alarm is installed

u too close to these appliances,it may alarm often and become a nuisance.

• Keep units at least 20 feet (6 meters) from the sources of combustion articles (stove, furnace, water heate r,space heater) if possible.In areas

p where a 20-foot (6m) distance is not possible – in modular, mobile, or smaller homes, for example – it is recommended the Alarm be placed as

ar from these fuel-burning sources as possible.The placement recom-

f mendations 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 an Alarm is placed dire ctly next to a fuel-burning source.Ve

• In direct sunlight.

• In turbulent air, like near ceiling fans or open windows. Blowing air may

prevent CO or gas from reaching the sensors.

• In areas where temperature is colder than 40˚ F (4˚ C) or hotter than

AVOIDING DEAD AIR SPACES

“Dead air”spaces may prevent gas from reaching the Alarm. To avoid dead air spaces,follow installation recommendations below.

On ceilings, install Alarms as close to the center of the ceiling as possible. If this is not possible, install the Alarm at least 4 inches (102 mm) from the wall or corner.

For wall mounting, the top edge of Alarms should be placed between 6 inches (152 mm) and 12 inches (305 mm) from the wall/ceiling line.

On a peaked,gabled, or cathedral ceiling, install Alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured horizontally.

ACT IVA T IN G T H E BATTERYBACK-UP

Activate the battery back-up by installing the battery. The battery is for backup only and is not intended to power the Alarm for an extended period of

me in the absence of AC.

The Alarm will light-up the display briefly to indicate the unit is receiving power.

DIRECT PLUG AL ARM INTO AN OUTLET (for Propane Detection)

his Alarm can be plugged directly into a wall outlet located close to the floor.

T This is the recommended configuration for detecting propane.

1. Choose a standard UNSWITCHED 120V AC outlet. . Plug Alarm in.

IF OUTLET IS MOUNTED HORIZONTALLY (SIDEWAYS)

If you are going to use your Alarm as a direct plug into an outlet that is

nted horizontally (sideways), you may want to rotate the adapter 90º,

mou as follows:

1. With back of unit facing you (AC blades on your left), place your left thumb

on adapter release and grab AC blades with your right hand to release the left side.

2. Repeat for the other side adapter thumb release. This will allow adapter to

slide out.

3. Remove adapter.

4. Rotate the adapter 90º and snap firmly back into place.

5. Plug Alarm into AC outlet.

WALL MOUNTED ALARM (for Natural Gas Detection)

Installation tips for power cord models: The powe r cord option provides

more flexibility in mounting locations and allows the Alarm to be easily installed at or above eye level.

NOTE: If you mount the Alarm high on a wall,make sure it is between 6 to 12 inches (152-3 05 mm) down from the ceiling. Any higher than this,it will be

in “dead air” space and carbon monoxide or natural gas may not reach the sensors.

his Gas/CO Alarm measures exposure to CO over time. It alarms if CO levels

e extremely high in a short period of time, or if CO levels reach a certain

ar minimum over a long period of time.The Gas/CO Alarm generally sounds an

larm before the onset of symptoms in average, healthy adults.Why is this

mportant? Because you need to be warned of a potential CO problem while

i you can still react in time. In many reported cases of CO exposure, victims

y be aware that they are not feeling well,but become disoriented and

n no longer react well enough to exit the building or get help. Also, young

ca children and pets may be the first affected.The average healthy adult might

t feel any symptoms when the Gas/CO Alarm sounds. However, people with

FINDING THE SOURCE OF CO AFTER AN ALARM

Carbon monoxide is an odorless, invisible gas,which often makes it difficult to locate the source of CO after an alarm.These are a few of the factors that can

• H roblem caused by “backdrafting.”

• P

• Transient CO problem caused by special circumstances.

Because CO may dissipate by the time an investigator arrives,it may be difficult

POTENTIAL SOURCES OF CO IN THE HOME

Fuel-burnin like:

wood burning fireplace, gas

itchen range or cooktop,

k gas clothes dryer.

Damaged or insufficient venting:

nected water heater vent pipe,leaking chimney pipe or flue, or cracked heat exchanger, blocked or clogged chimney opening.

Improper use of appliance/ device: operating a barbecue

grill or vehicle in an enclosed area (like a garage or screened porch).

Transient CO Problems: “transient” or on-again-off-again CO problems can be caused by outdoor conditions and other special circumstances.

The following conditions can result in transient CO situations:

1. Excessive spillage or reverse venting of fuel appliances caused by outdoor

2. Extended operation of unvented fuel burning devices (range, oven,fireplace). 3

. Temperature inversions,which can trap exhaust close to the ground.

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

• Clean chimneys and flues yearly. Keep them free of debris, leaves,and sts for proper air flow. Also, have a professional check for rust and

ne corrosion,cracks, or separations. These conditions can prevent proper air movement and cause backdrafting. Never “cap” or cover a chimney

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

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

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

REGULATORY INFORMATION FOR EXPLOSIVE GAS/CO ALARMS

REGULATORY INFORMATION FOR CO ALARMS

WHAT LEVELS OF CO CAUSE AN ALARM?

Underwriters Laboratories Inc. Standard UL2034 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).

UL2034 Required Alarm Points*:

• If the alarm is exposed to 400 ppm of CO, IT MUST AL ARM BET WEEN

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 MUSTALARM BET WEEN

60 and 240 MINUTES.

* Approximately 10% COHb exposure at levels of 15% to 95% Relative Humidity (RH).

The unit is designed not to alarm when exposed to a constant level of 30 ppm for 30 days.
