(1) PRODUCT INFORMATIONThe SimpliSafe Wireless Smoke/CO Detector (CA002) is a combined
photoelectric Smoke Detector and Carbon Monoxide Detector (referred to inthis Owner’s Manual as the “Smoke/CO Detector”).

(4 loud beeps followed by a pause). The CO detector also transmits an alarm
signal to the Base Station.
The alarm automatically resets when CO is no longer detected.

A. Smoke Detection

The Smoke/CO Detector also monitors low battery, wall tamper and sensor
end-of-life conditions. These trouble codes are NOT transmitted to the Base
Station. You will hear and see them coming from the Smoke/CO Detector.

The Smoke/CO Detector is designed to sense smoke that comes into thedetector chamber and gives early warning of developing fires with an alarmsound from its built-in siren. The built-in wireless transmitter also causes yourSimpliSafe Base Station siren to sound.

The SimpliSafe Smoke/CO Detector is intended only for residential indoor
applications and other areas approved by an Authority Having Jurisdiction(AHJ), which in many jurisdictions may be your local fire department or fire
marshall. It is not intended for use in commercial applications.

These sirens can provide precious time to escape before a fire spreads.
However, such pre-warning of fire is only possible if the Smoke/CO Detector
is located, installed and maintained properly as described in this Owner’s
Manual.

(2) IMPORTANT WARNING STATEMENTS

The Smoke/CO Detector also monitors low battery and sensor malfunctions.
These trouble conditions will cause an audible chirp from the Smoke/CO
Detector as described in Section 4 on “Usage, Operation and Operating
Modes’’ below.
B. Carbon Monoxide (CO) Detection
The Smoke/CO Detector also monitors the level of CO gas in your home andgives early warning when a potentially dangerous level exists. It does notdetect any other gas.
If a dangerous concentration of CO is detected, the red light on the front of
the detector turns on and flashes four times, and an internal siren sounds

tests all functions as required by Underwriters’ Laboratories.
WARNING: When you are not testing the unit and the alarm siren sounds,
the detector is warning of a possible serious situation, which requires yourimmediate attention.
WARNING: This device contains a wireless transmitter that can actuatea remote audible siren. When used in a typical single level or multilevel
dwelling, or in apartment buildings where adjacent apartments may have
similar systems, it is possible that interference for another system could4prohibit the remote siren from sounding in the event of an alarm. Never
rely solely on the remote siren for notification of an alarm. Always makesure that the internal siren in the Smoke/CO Detector can be heard from all
bedrooms and living areas.
WARNING: Actuation of your CO alarm indicates the presence of carbon
monoxide which can KILL YOU. If the alarm signal sounds:(1) Press the mute button(2) Call your emergency services (fire department or 911)
(3) Immediately move to fresh air – outdoors or by an open door/window. Do
a headcount to check that all persons are accounted for. Do not reenter thepremises nor move away from the open door/window until the emergency
services responders have arrived, the premises have been aired out, andyour alarm remains in its normal condition.
(4) After following steps 1–3, if your alarm reactivates within a 24 hour period,
repeat steps 1–3 and call a qualified appliance technician to investigate forsources of CO from fuel burning equipment and appliances, and inspect for
proper operation of this equipment. If problems are identified during thisinspection, have the equipment serviced immediately. Note any combustion
equipment not inspected by the technician and consult the manufacturers’
instructions, or contact the manufacturers directly, for more information
about CO safety and this equipment. Make sure that motor vehicles are not,and have not been, operating in an attached garage or adjacent to theresidence.
WARNING: Smoke detectors CANNOT provide warnings for fires resulting
from explosions, smoking in bed or other furniture, ignition of flammableliquids, vapors and gasses, children playing with matches or lighters.

WARNING: Smoke detectors are not to be used with detector guards
unless the combination has been evaluated and found suitable for that
purpose.
CAUTION: Early warning fire detection is best achieved by the
installation of fire detection equipment in all rooms and areas of thehousehold as follows:
A smoke alarm or detector installed in each separate sleeping room, outsideof each separate sleeping area, in the immediate vicinity of the sleeping
rooms, and on each level of the dwelling unit, including basements and heator smoke detectors in living rooms, dining rooms, kitchens, hallways, attics,
furnace rooms, closets, utility and storage rooms, and attached garages.
CAUTION: This carbon monoxide alarm is designed to detect carbon
monoxide from ANY source of combustion. It is NOT designed to detect fire,or any other gas.
CAUTION: The CO alarm will only indicate the presence of carbon
monoxide at the sensor. Carbon monoxide may be present in other areas.
CAUTION: This Smoke/CO Detector comes with cover latches that will
prevent the Smoke/CO Detector cover from closing if the batteries are notinstalled. This tells you that the Smoke/CO Detector will not work until a newbattery is properly installed.
CAUTION: Continuous exposure to the high sound level of this alarm overan extended period of time may cause hearing loss.

IMPORTANT: You should never disable the unit to avoid nuisance alarms.
Instead, relocate the detector to a better location.

B. Locations to Avoid
To avoid false alarms and optimize detection of real alarms, do not install a
Smoke/CO Detector:• In locations where combustion particles may normally be present, suchas garages where there may be vehicle exhaust, near furnaces, hotwater heaters, and space heaters. We recommend leaving at least 20 feetbetween the detector and such locations.
• In very dusty or dirty areas. Dirt and dust can build up on the sensing
chamber, making it overly sensitive, or block openings to the sensing
chamber, making it less sensitive.
• In insect-infested areas. If insects enter the sensing chamber, they may
cause a nuisance alarm. Where bugs are a problem, get rid of them
before putting up a detector.
• Near fluorescent lights. Electrical “noise” from fluorescent lights may
cause nuisance alarms. Install Smoke/CO Detectors at least 5 feet (1.5
meters) from such lights.
• Near any cooking appliances. Install Smoke/CO Detectors at least 5 feet
(1.5 meters) from any cooking appliances.
IMPORTANT: You should never disable the unit to avoid nuisance alarms.
Instead, relocate the detector to a better location.
WARNING: Never remove the battery from the Smoke/CO Detector tostop a nuisance alarm. Open a window or fan the air around the Smoke/
CO Detector to get rid of the smoke. The detector will turn itself off when
the smoke is gone. If nuisance alarms persist, attempt to clean the Smoke/
CO Detector as described in this Owner’s Manual, or relocate it to a better
location.

If this detector is paired to a Base Station, the Base Station will also soundduring this test if no issues are found.
If the Smoke/CO Detector and Base Station do not sound, the detector either
has a low battery, or the detector is malfunctioning. Replace the batteries inthe detector, and repeat the test.
This is the only way to make sure that the Smoke/CO Detector unit isworking properly. If the unit fails to test properly with new batteries, have it
replaced immediately.
CAUTION: Continuous exposure to the high sound level of this alarm overan extended period of time may cause hearing loss.
WARNING: Never use an open flame of any kind to test your detector.
You may damage it as well as your home. The built-in test switch accurately
tests all functions as required by Underwriters’ Laboratories.
WARNING: When you are not testing the unit and the alarm siren sounds,
the detector is a warning of a possible serious situation, which requires yourimmediate attention.

(5) LIMITATIONS OF THE SMOKE/CO DETECTOR
A. Limitations of Wireless Smoke Detectors
Wireless smoke detectors cannot provide total protection of life or property
and are not a substitute for insurance. All wireless smoke detectors are
subject to possible compromise or failure-to-warn for a variety of reasons.
For example:• Smoke detectors require a source of power to work. This Smoke/CO
Detector will not operate and the alarm will not sound if batteries aredead or not installed properly.
• Smoke detectors may not be heard. A sound sleeper or someone who
has taken drugs or alcohol may not awaken if the detector is installedoutside a bedroom. It is the responsibility of individuals in the householdthat are capable of assisting others to provide assistance to those
who may not be awakened by the alarm sound, or those who may beincapable of safely evacuating the area unassisted.
• Closed or partially closed doors and distance can block sound.
• This Smoke/CO Detector is not designed for the hearing impaired.
• Radio signals transmitted by this Smoke/CO Detector may be blocked
or reflected by metal objects. Adjacent devices or systems using radio
frequency signals may interfere with the operation of this alarm.
• Test the system weekly to ensure signals are transmitted and received
properly• Smoke detectors may not detect smoke on other levels of the building.
21• Smoke detectors may not always activate and provide warning earlyenough.
• A smoke detector only activates when enough smoke reaches it.
• If a fire starts in a chimney, wall, roof, on the other side of closed doors,
or a different level of the property, not enough smoke may reach thedetector.
• Smoke Detectors may not be effective in fires where the victim is
intimate with a flaming initiated fire; for example when a person’s clothes
catch fire while cooking.
• Smoke Detectors may not be effective in fires where the smoke isprevented from reaching the smoke alarm due to a closed door or otherobstruction.
• Smoke Detectors may not be effective in incendiary fires where the firegrows so rapidly that an occupant’s egress is blocked even with properly
located smoke alarms.
• Smoke detectors are a significant help in reducing loss, injury and evendeath.
• No matter how good a detection device is, nothing works perfectly under
every circumstance. We must warn you that you cannot expect a Smoke/
CO Detector to ensure that you will never suffer any damage or injury.
B. Limitations of Wireless CO Detectors
Wireless CO detectors provide early warning of the presence of CO, usually
before a healthy adult would experience symptoms. This early warning
is possible only if your Smoke/CO Detector is located, installed, andmaintained as described in this Owner’s Manual.
22

Because CO is a cumulative poison, long-term exposures to low levels may
cause symptoms, as well as short-term exposures to high levels. This unit hasa time-weighted alarm. The higher the level of CO present, the sooner thealarm will be triggered.
This Smoke/CO Detector can only warn you of the presence of CO. It does
not prevent CO from occurring, nor can it solve an existing CO problem.
If your unit has alarmed and you’ve provided ventilation by leaving yourwindows and doors open, the CO buildup may have dissipated by thetime help responds. Although your problem may appear to be temporarily
solved, it is crucial that the source of the CO is determined and that theappropriate repairs are made.
Wireless CO detectors have limitations. Like any other electronic device, CO
detectors are not foolproof. CO detectors have a limited operational life.
You must test your Smoke/CO Detector weekly, because it could fail tooperate at any time.
If your Smoke/CO Detector fails to test properly, or if its self-diagnostic test
reveals a malfunction, immediately have the unit replaced. This detector will
not monitor CO levels while in a trouble condition.
The Smoke/CO Detector can only sense CO that reaches the unit’s sensor.
It is possible that CO may be present in other areas without reaching thealarm. The rate and ability with which CO reaches the alarm may beaffected by:• Doors or other obstructions.
• Fresh air from a vent, an open window, or other source.
23• CO being present on one level of the home and not reaching a CO alarm
installed on a different level. (For example, CO in the basement may notreach an alarm on the second level, near the bedrooms).
For these reasons, we recommend you provide complete coverage byplacing a Smoke/CO Detector on every level of the home.
(6) FIRE PREVENTION AND ESCAPE
The purpose of an early warning smoke detector is to detect the presenceof fire in its early stages and sound an alarm giving the occupants time toexit the premises safely. No detection device can protect life in all situations.
Therefore, safeguards should be taken to avoid potentially dangerous
situations as follows:
In Case of FireIn the event of a fire, you should do the following:• Leave immediately. Don’t stop to pack or search for valuables.
• In heavy smoke, hold your breath and stay low, crawl if necessary. The
clearest air is usually near the floor.
• If you have to go through a closed door, carefully feel the door and door
knob to see if undue heat is present. If they seem cool, brace your footagainst the bottom of the door with your hip against the door and one
hand against the top edge. Open it slightly. If a rush of hot air is felt, slamthe door quickly and latch it. Unvented fire tends to build up considerablepressure. Be sure all members of the household realize and understandthis danger.
• Use your neighbor’s phone or a street fire alarm box to call the fire
department. The job of extinguishing the fire should be left to theprofessionals.

24

Be Prepared
Use the following instructions to create an emergency evacuation plan:• Draw a floor plan showing all doors and windows and show two exits
from each room.
• Check that the doors and windows in each room open easily and you
can use them to get outside• If you have children and/or physically challenged people residing in yourhousehold, use window decals to help emergency personnel identify thesleeping quarters of these individuals.
• Ensure smoke alarms are properly placed. Test them weekly.
• Establish one meeting place outside the home. Insist that everyone
meet there during an alarm. This will eliminate the tragedy of someone
reentering the house for a missing member who is actually safe.
• Make sure your house or building number is visible from the street• Learn the emergency phone number for your fire department.
• Review the plan with everyone in your home. It is important that children
be instructed carefully, because they tend to hide in times of crisis.
• Perform fire drills regularly. Use them to assure recognition of an alarm
signal.
Avoid Fire Hazards• Do not smoke in bed.
• Do not leave children home alone.
• Never clean with flammable liquids such as gasoline.
• Properly store materials. Use general good housekeeping techniques tokeep your home neat and tidy. A cluttered basement, attic, or storage
area is an open invitation to fire.
25• Use combustible materials and electrical appliances carefully and only
for intended uses.
• Do not overload electrical outlets.
• Do not store explosive and/or fast burning materials in your home.
• Even after proper precautions have been taken, fires can start. Be
prepared.
WARNING: Smoke detectors CANNOT provide warnings for fires resulting
from explosions, smoking in bed or other furniture, ignition of flammableliquids, vapors and gasses, children playing with matches or lighters.
WARNING: Smoke detectors are not to be used with detector guards
unless the combination has been evaluated and found suitable for that
purpose.
WARNING: This device contains a wireless transmitter that can actuatea remote audible siren. When used in a typical single level or multilevel
dwelling, or in apartment buildings where adjacent apartments may have
similar systems, it is possible that interference for another system could
prohibit the remote siren from sounding in the event of an alarm. Never
rely solely on the remote siren for notification of an alarm. Always makesure that the internal siren in the Smoke/CO detector can be heard from all
bedrooms and living areas.
(7) INFORMATION ABOUT CARBON MONOXIDE (CO)A. Description of CO and Important Information
Carbon monoxide is a colorless, odorless, and tasteless poison gas that canbe fatal when inhaled. CO inhibits the blood’s capacity to carry oxygen.

Periodically review this Owner’s Manual and discuss your CO alarm
emergency procedure with all members of your family.
• Never ignore a CO alarm.
• A true alarm is an indication of potentially dangerous levels of CO.
• CO alarms are designed to alert you to the presence of CO before an
emergency - before most people would experience symptoms of CO
poisoning, giving you time to resolve the problem calmly.
• Determine if anyone in the household is experiencing symptoms of CO
poisoning.
• Many cases of reported CO poisoning indicate that while victims areaware they are not well, they become so disoriented they are unable tosave themselves either by exiting the building or calling for assistance.
• Young children and household pets may be the first affected.
• You should take extra precautions to protect high-risk persons from CO
exposure because they may experience ill effects from CO at levels thatwould not ordinarily affect a healthy adult.
B. Symptoms of CO Poisoning
The following common symptoms are related to CO poisoning and should be
discussed with ALL members of the household:• Mild exposure = Slight headache, nausea, vomiting, fatigue (often
described as “flu-like” symptoms).
• Medium exposure = Severe throbbing headache, drowsiness, confusion,
fast heart rate.
• Extreme exposure = Unconsciousness, convulsions, cardio-respiratory
failure, death.
27• Many cases of reported CARBON MONOXIDE POISONING indicate thatwhile victims are aware they are not well, they become so disoriented
they are unable to save themselves by either exiting the building or
calling for assistance.
• Young children and household pets are typically the first affected.
If you experience even mild symptoms of CO poisoning, consult your doctor
immediately.
C. Conditions that Can Produce CO
Excessive spillage or reverse venting of fuel burning appliances caused by:• Outdoor ambient conditions such as wind direction and/or velocity,
including high gusts of wind; heavy air in the vent pipes (cold/humid air
with extended periods between cycles).
• Negative pressure differential resulting from the use of exhaust fans.
• Simultaneous operation of several fuel burning appliances competing for
limited internal air.
• Vent pipe connection vibrating loose from clothes dryers, furnaces, orwater heaters.
• Obstructions in or unconventional vent pipe designs which amplify theabove situations.
• Extended operation of unvented fuel burning devices (range, oven,
fireplace, etc.).
• Temperature inversions which can trap exhaust gasses near the ground.
• Car idling in an open or closed attached garage, or near a home.

D. What to Do In the Event of a CO Alarm(8) REGULAR MAINTENANCEWARNING Actuation of your Smoke/CO Detector indicates the presenceof carbon monoxide which can KILL YOU. If the alarm signal sounds:

To keep your Smoke/CO Detector in good working order, remove frommounting bracket, remove battery cover and vacuum the dust off thesensing chamber at least once a month.

(1) Press the mute button(2) Call your emergency services (fire department or 911)
(3) Immediately move to fresh air – outdoors or by an open door/window.
Do a headcount to check that all persons are accounted for. Do notreenter the premises nor move away from the open door/window until
the emergency services responders have arrived, the premises have been
aired out, and your alarm remains in its normal condition.

• Remove the batteries before cleaning.
• Use soft brush attachment on your vacuum to carefully remove any dust,
especially on the openings of the sensing chamber. Never use water orcleaners - they may damage the unit.
• Replace the batteries after cleaning.
• Test the detector to make sure the batteries are working correctly.
• Avoid spraying air fresheners, hair spray, paint, or other aerosols near
the detector.

(4) After following steps 1–3, if your alarm reactivates within a 24 hour
period, repeat steps 1–3 and call a qualified appliance technician
to investigate for sources of CO from fuel burning equipment andappliances, and inspect for proper operation of this equipment. If
problems are identified during this inspection, have the equipment
serviced immediately.
Note any combustion equipment not inspected by the technician andconsult the manufacturers’ instructions, or contact the manufacturers
directly for more information about CO safety and this equipment. Make
sure that motor vehicles are not, and have not been, operating in an
attached garage or adjacent to the residence.
