Where to Install

Minimum coverage for Smoke Alarms, as recommended by the National Fire Protection Association (NFPA), is one Smoke Alarm on every ﬂoor, in every sleeping area, and in every bedroom (See “Regulatory Information For Smoke Alarms” 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 15 feet (4.6 meters) away from the

furnace or fuel burning heat source where possible. In smaller homes or in manufactured homes 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 15 feet (4.6 meters) will not harm the Alarm, but may increase the frequency of unwanted alarms.

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 (4.4˚ C and 37.8˚ C).

Recommended Placement

• When installing on the wall, the top edge of Smoke Alarms should be placed between

4 inches (102 mm) and 6 inches (153 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 Not to Install

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, near ceiling fans or open windows. Blowing air may prevent CO/smoke from reaching the

sensors.

• In areas where temperature is colder than 40˚ F (4.4˚C) or hotter than 100˚ F (37.8˚C). These areas include

non air conditioned crawl spaces, unﬁnished attics, uninsulated or poorly insulated ceilings, porches, and garages.

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

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

• In “dead air” spaces. See below for additional information.

Installing Smoke/CO Alarms in Mobile Homes

“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.

Set-Up & Installation

Speaker

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

NOTE: Be sure to mount the product in the orientation speciﬁed in the next steps as this

provides the most stability for mounting the product to the wall or ceiling. When wall mounting, it is suggested that the horn opening is in the upper left corner.

This alarm is designed to be mounted on the ceiling or wall if necessary.

Ensure the iOS software is updated to iOS 9.

Step 1 Download the free Onelink app from the App

Store and follow set-up instructions.

Step 2 Hold the mounting bracket against the ceiling

(or wall) so the two universal mounting holes are aligned approximately at the 9 and 3 o’clock positions. (See image). Trace around the holes with a pencil.

Step 3 Put the unit where it won’t get covered with

dust when you drill the mounting holes.

Step 4 Using a 3/16” (5 mm) drill bit, drill a hole

through the center of the outlines you traced.

Step 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.

Step 6 Install the screws but do not tighten completely. Attach the mounting bracket by aligning the screws in the

open portion of the universal mounting slots and rotating the bracket into place. Tighten the screws until they are snug to secure the bracket. Do not over tighten.

Step 7 Mount alarm to mounting bracket to activate the alarm. Once unit is activated, it cannot be turned off.

NOTE: After you activate the Alarm, the Color Indicator Ring will power up and the Alarm will welcome you.

To program your alarm, follow the instructions provided in the Onelink app.
