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 ￿ before beginning any installation.

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

When installing on the wall, the top edge of Smoke Alarms should be placed between 4 inches (102 mm) and 12 inches (305 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.

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.

WHERE THIS ALARM SHOULD NOT BE INSTALLED

Do NOT locate this Smoke/CO Alarm:

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

Within 5 feet (1.5 meters) 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.

In areas where temperature is colder than 40˚ F (4˚ C) or hotter than 100˚F (38˚ C). These areas include non-airconditioned crawl spaces, unfinished attics, uninsulated or poorly insulated ceilings, porches, and garages.

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.

In “dead air” spaces. See “Avoiding Dead Air Spaces”.

AVOIDING DEAD AIR SPACES

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

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.

For wall mounting (if allowed by building codes), the top edge of Smoke/CO 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 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.

HOW TO INSTALL THIS ALARM

This combination Smoke/CO Alarm was designed to be mounted on the ceiling or wall. It is not a tabletop device. You must install this device on the ceiling or wall as outlined below. Read “Where To Install This Alarm” before starting.

PARTS OF THIS SMOKE/CO ALARM

1 Test/Silence Button

2 Battery Compartment

3 Power/Smoke Alarm LED

4 CO Alarm LED

Tools you will need: pencil, drill with 3/16” or 5mm drill bit, flathead screwdriver, hammer.

Do not connect this unit to any other alarm or auxiliary device. It is a single-station unit that cannot be linked to other devices. Connecting anything else to this unit may prevent it from working properly.

Do not install this unit over an electrical junction box. Air currents around junction boxes can prevent smoke from reaching the sens- ing chamber and prevent the unit from alarming. Only AC powered units are intended for installation over junction boxes.

If you want to lock the battery compartment, or lock the Smoke/CO Alarm to the mounting bracket, please read the “Optional Locking Features” section.

1.Hold base firmly and twist the mounting bracket counterclockwise (left) to separate it from the unit.

2.Hold the mounting bracket against the ceiling (or wall) so the vertical mounting slot is aligned in the 12 o’clock position and trace around the inside of the mounting slots (vertical and horizontal mounting).

3.Put the unit where it won’t get covered with dust when you drill the mounting holes.

4.Using a 3/16” (5 mm) drill bit, drill a hole through the center of the oval outlines you traced.

5.Insert the plastic screw anchors (in the plastic bag with screws) into the holes. Tap the screw anchors gently with a hammer, if necessary, until they are flush with the ceiling or wall.

6.Line the mounting bracket up over the plastic screw anchors.

7.Screw the mounting bracket to the ceiling or wall through the mounting slots using the two screws provided.

8.Before attaching the Alarm to

the bracket, insert the two (2)

AA batteries (included) into the battery compartment. Match the terminals on the end of the battery with the terminals on the unit. Match “+” to “+” and “-” to “-.” If the batteries are

not fully inserted, the unit cannot receive battery power.

NOTE: The unit may beep briefly when you install the batteries. This is normal. The GREEN Light flashes about every 60 seconds when the unit is receiving battery power.

The battery door will resist closing unless batteries are installed. This warns you the unit will not operate without batteries.

9. Attach the Smoke/CO Alarm to the mounting bracket. Line up the guides on the alarm’s base with the guides on the mounting bracket. When guides are lined up, turn the base clockwise (right) until it snaps into place.

NOTE: Once the Smoke/CO Alarm is snapped onto the mounting bracket, you can rotate the Smoke/CO Alarm to adjust the alignment.

10. Test the Smoke/CO Alarm. See “Weekly Testing” for details.
