•

Intelligent Sensing Technology–Reduces the number of non-emergency or “nuisance” alarms.

•

Latching Alarm Indicator–Identifies the initiating alarm even after the alarm condition is over or power is stopped.

•

Interconnectable–With BRK smoke and carbon monoxide alarms.

•

Two Silence Features–

1. Temporarily silence the low battery chirp for up

to 8 hours.

2. Temporarily silence an unwanted alarm for

several minutes.

•

Automatically performs internal self tests.

•

Battery Compartment–Swings out for quicker, easier battery installation.

•

AC/DC Alarm–Operates on household voltage with a 9V battery back-up.

THE CO ALARM

The Carbon Monoxide (CO) Alarm measures CO levels in the air. It will alarm if CO levels rise quickly (if the heat exchanger on your furnace breaks, for example), or if CO is consistently present (a slow CO leak in your stove or water heater).

THE SMOKE ALARM

The Smoke Alarm monitors the air for the presence of combustion particles (produced when something burns). When enough combustion particles reach the smoke sensing chamber, it triggers an alarm.

CHAPTER 1: INTRODUCTION

BASIC SAFETY INFORMATION

Dangers, Warnings, and Cautions alert you to important operating instructions or to potentially hazardous situations. Pay special attention to these items.

This combination Smoke and Carbon Monoxide Alarm will only indicate the presence of smoke or CO at the sensor. Carbon Monoxide gas or smoke may be present in other areas. The unit is not designed to sense other gases, heat or flames.

This Smoke/CO Alarm is approved for use in single-family residences. It is NOT designed for marine or RV use.

This device is not intended to alert hearing impaired residents. Smoke alarms specifically designed for the hearing impaired, which feature devices like flashing strobe lights, are available to alert the hearing impaired in case of fire.

ELECTRICAL SHOCK HAZARD. Turn off power to the area where you will install this unit at the circuit breaker or fuse box before beginning installation. Failure to turn off the power before installation may result in serious electrical shock, injury or death.

Basic safety information (continued)...

Installation of this unit must conform to the electrical codes in your area; Article 760 of NFPA 70 (NEC), NFPA 72, NFPA 101; SBC (SBCCI); UBC (ICBO); NBC (BOCA); OTFDC (CABO), and any other local or building codes that may apply. Wiring and installation must be performed by a licensed electrician. Failure to follow these guidelines may result in injury or property damage.

This unit must be powered by a 24-hour, 120VAC 60Hz circuit. Be sure the circuit cannot be turned off by a switch, dimmer, or ground fault circuit interrupter. Failure to connect this unit to a 24-hour circuit may prevent it from providing constant protection.

This Alarm must have AC or battery power to operate. If the AC power fails, battery back-up will power the Alarm for 20 hours providing the 9V battery is fresh and correctly installed. If AC power fails and the battery is dead or missing, the Alarm cannot operate.

NEVER ignore any alarm. Refer to Chapter 3 for more information on how to respond to an alarm. Failure to respond can result in injury or death.

Basic safety information (continued)...

Never disconnect the AC power or remove the battery from the unit to stop an unwanted alarm (caused by cooking smoke, etc.). Doing so will disable the unit and remove your protection. In the case of a true unwanted smoke alarm, use the Silence Feature, open a window or fan the smoke away from the unit. The alarm will reset automatically when it returns to normal operation.

Connect this unit ONLY to other compatible units. See “Interconnecting Multiple Alarms” in the “How To Install This Alarm” section for details. Do not connect it to any other type of alarm or auxiliary device. Connecting anything else to this unit may damage it or prevent it from operating properly.

Do not stand too close to the unit when the alarm is sounding. It is loud to wake you in an emergency. Exposure to the horn at close range may harm your hearing. When testing the unit, step back when the horn starts sounding.

The Silence Feature is for your convenience only and will not correct a problem. See Chapter 3 for details on using the Silence Feature.

Specifications (continued)...

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, 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.

This CO Alarm is designed to alert you to a potentially dangerous build-up of CO over time. It cannot fix a CO problem, and it cannot identify a specific source of CO. The company shall not be obligated to pay for any carbon monoxide investigation or service call conducted by a Fire Department, or licensed investigator or repairman, arranged by the homeowner in response to an alarm.

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 may consider using warning devices which provide audible and visual signals for carbon monoxide concentrations under 30 ppm.

In general, install combination Smoke and Carbon Monoxide 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 40 feet (12 meters) long, install a unit at each end.

• At the top of first-to-second floor stairs.

• 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˚C and 38˚C).

Recommended Placement

• When installing on the wall, the top edge of Smoke/CO Alarms should be placed between 4 inches (102 mm) and 6 inches (152 mm) from the wall/ceiling line.

• When installing on the ceiling, place the Alarm as close to the center as possible.

• In either case, install at least 4 inches (102 mm) from where the wall and ceiling meet. See “Avoiding Dead Air Spaces” for more information.

NOTE: For any location, make sure no door or other obstruction could keep carbon monoxide or smoke from reaching the Alarm.

CHAPTER 2: INSTALLATION

WHERE TO INSTALL THIS ALARM

Minimum coverage for Smoke Alarms, as recom-

mended by the National Fire Protection Association (NFPA), is one Smoke Alarm on every floor, in every sleeping area, and in every bedroom (See Chapter 8 for details on the NFPA recommendations).

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 20 feet (6 meters) away from the furnace or fuel burning heat source where possible. In smaller homes or in manufactured homes and RV’s 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 20 feet will not harm the Alarm, but may increase the frequency of nuisance alarms.

Installing Smoke/CO Alarms in Mobile Homes

For minimum security install one Smoke/CO Alarm as close to each sleeping area as possible. For more security, put one unit in each room. Many older mobile homes (especially those built before 1978) have little or no insulation. If your mobile home is not well insulated, or if you are unsure of the amount of insulation, it is important to install units on inside walls only.

SMOKE ALARM WITH SILENCE FEATURE

CO ALARMS

BOTH, OR COMBINATION SMOKE/CO ALARMS

Suggested locations are based on NFPA recommendations (NFPA 72 for Smoke Alarms and NFPA 720 for Carbon Monoxide Alarms). Always refer to national and local codes

In new construction AC and AC/DC smoke alarms MUST be interconnected to meet NFPA recommendations.

This combination Smoke/CO Alarm can be interconnected with all compatible AC and AC/DC Smoke Alarms and other same-model Smoke/CO Alarms. It is not recommended that you interconnect this Smoke/CO Alarm with othermodel AC or AC/DC CO Alarms.

before beginning any installation.

AVOIDING DEAD AIR SPACES

“Dead air” spaces may prevent smoke from reaching the Smoke/CO Alarm. To avoid dead air spaces, follow installation recommendations:

On ceilings,

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

On a peaked, gabled, or cathedral ceiling, install first

Smoke/CO Alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured horizontally. Additional Smoke/CO 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.

For wall mounting (if allowed by building codes), the top edge of Smoke/CO Alarms should be placed between 4 inches (102 mm) and 6 inches (152 mm) from the wall/ceiling line, below typical “dead air” spaces. NOTE: Position the battery drawer, marked “THIS SIDE UP”, so it faces the ceiling.

WHERE NOT TO INSTALL THIS ALARM

Do NOT locate this Smoke/CO Alarm:

• In garages, kitchens, furnace rooms, crawl spaces and unfinished attics. Avoid extremely dusty, dirty or greasy areas.

• Where combustion particles (formed when something burns) are produced. Avoid poorly ventilated kitchens, garages, and furnace rooms. Keep this Smoke/CO Alarm at least 20 feet (6 meters) from a furnace or other fuel burning heat source, or fuel burning appliances (water heater, stove, vehicle, furnace) whenever possible.

• Within 5 feet of any cooking appliance. In air streams near kitchens. Air currents can draw cooking smoke into the smoke sensor and cause unwanted alarms.

• In extremely humid areas. This Alarm should be at least 10 feet (3 meters) from a shower, sauna, humidifier, vaporizer, dishwasher, laundry room, utility room, or other source of high humidity.

• In direct sunlight.

• In turbulent air, like near ceiling fans or open

windows. Blowing air may prevent CO or smoke from reaching the sensors.

• Where the temperatures are regularly below 40˚ F (4˚C) or above 100˚ F (38˚ C) including unheated buildings, outdoor rooms, porches, or unfinished attics or basements. Extreme temperatures may shorten component or battery life.

• In insect infested areas. Insects can clog the openings to the sensing chamber.

• Less than 12 inches (305 mm) away from fluorescent lights. Electrical “noise” can interfere with the sensor.

IMPORTANT INSTALLATION PARTS

The Mounting Bracket:

To remove the mounting bracket from the Smoke/CO Alarm base, hold the alarm base firmly and twist the mounting bracket off. The mounting bracket installs onto the junction box. It has a variety of screw slots to fit most boxes.

The Power Connector: The power connector plugs into a power input block on the Smoke/CO Alarm. It supplies the unit with AC power.

• The black wire is “hot.”

• The white wire is neutral.

• The white/gray stripe wire is used for

interconnect.

ELECTRICAL SHOCK HAZARD. Turn off the power to the area where the Alarm is installed before removing it from the mounting bracket. Failure to turn off the power first may result in serious electrical shock, injury or death.

If you need to remove the power connector, insert a flat screwdriver blade between the power connector and the security tab inside the power input block. Gently pry back the tab and pull the connector free.

LOCKING FEATURES

The locking features are designed to prevent unauthorized removal of the battery or Alarm. It is not necessary to activate the locks in single-family households where unauthorized battery or Alarm removal is not a concern.

These Alarms have two separate locking features: one to lock the battery compartment, and the other to lock the Alarm to the mounting bracket. You can choose to use either feature independently, or use them both.

Tools you will need: • Needle-nose pliers or utility knife • Standard/Flathead screwdriver.

Both locking features use locking pins, which are molded into the mounting bracket. Using needle nose pliers or a utility knife, remove one or both pins from the mounting bracket, depending on how many locking features you want to use.

To permanently remove either lock, insert a flathead screwdriver between the locking pin and the lock, and pry the pin out of the lock.

Locking Pin

TO LOCK THE BATTERY COMPARTMENT

This step should not be done until installation is complete and AC power can be turned on as soon as possible to conserve battery power. Activate the battery and test the battery back-up before locking the battery compartment.

1. Activate the battery back-up by

removing the “Pull to Activate Battery Back-Up” tab.

2. Push and hold Test/Silence

button until the alarm sounds.

If the unit does not alarm during testing, install a new battery and test again. If the alarm still does not sound, replace it immediately.

3. Using needle-nose pliers

or a utility knife, detach one locking pin from the mounting bracket.

4. Push the locking pin through

the black dot on the label on the back of the Smoke/CO Alarm.

TO UNLOCK THE BATTERY COMPARTMENT

Once the Alarm is installed, you must disconnect it from the AC power before unlocking the battery compartment.

1. Remove the Alarm from the mounting bracket. If the unit is locked to the bracket, see the section “To Unlock the Mounting Bracket.”

2. Disconnect the power connector by gently prying it away from the back of the Smoke/CO Alarm.

3. Insert a flathead screwdriver under the head of the locking pin, and gently pry it out of the battery compartment lock. (If you plan to relock the battery compartment, save the locking pin.)

4. To relock the battery compartment, close the battery drawer and reinsert locking pin in lock.
