This user manual contains important information about your combination smoke and carbon monoxide alarm’s
operation. To ensure proper use and trouble-free operation, please read this manual carefully and store it in a safe
place for future reference.
1 Introduction
This X-SENSE combination smoke and carbon monoxide alarm detects both smoke and carbon monoxide, meeting
UL 217 Ed.9 (designed to reduce false alarms from cooking fumes) and UL 2034 Ed.5 standards.
This unit adopts photoelectric technology to detect smoke which is generally more sensitive than ionization
technology. It is effective at detecting large particles, which tend to be produced in greater amounts by smoldering
fires. These types of fires may smolder for hours before bursting into flame. Sources of these fires may include
cigarettes burning in couches or bedding.
Carbon monoxide (CO) is odorless, tasteless and invisible—it's a silent killer. Using electrochemical sensing
technology, this unit can detect increased levels of carbon monoxide early, protecting your family from the dangers
of carbon monoxide.
1. The installation of the apparatus should not be used as a substitute for proper installation, use and maintenance
of fuel-burning appliances including appropriate ventilation and exhaust systems.
2. This apparatus is to be installed by a competent person.
3. It is not tested for use in a caravan or boat.
Note: For maximum protection, use smoke and CO alarms on each level and in every bedroom of your home.
NEVER IGNORE THE SOUND OF THE ALARM!
Determining what type of alarm has sounded is easy with your X-SENSE combination smoke and carbon monoxide
alarm. The buzzer will inform you of the type of situation occurring.

Test/Silence Button
The Test/Silence button is used to test the unit's electronics and to silence the unit during an alarm. When testing
the alarm weekly, you should first wake up your alarm by pressing the test button; once the alarm has woken up,
the LCD display will activate, then press and hold the test button again until you hear a short beep, indicating that
the alarm has entered the test mode. Please refer to the “Alarm Test” section for further information. The alarm goes
back to the standby mode after testing. To save power, the alarm is designed to automatically turn off the LCD
display if there has been no operation for 5 minutes.
NOTE: After a test has begun, the alarm will sound and the LED indicator will flash red. This does not indicate that
smoke/CO is present.
Silence Mode
Smoke Silence Mode: Press the test button during an alarm to have the unit enter silence mode for 9 minutes. If the
smoke concentration has reached an alarm level, after the silence time has expired, this unit will continue to alarm
until the smoke concentration decreases to a safe, low level. Otherwise, the alarm will enter the normal mode after
9 minutes.
NOTE: Before silencing a smoke alarm, check the surrounding area for smoke, flames, or any signs of fire. Only
silence the alarm after confirming there is no real danger.
CO Silence Mode: Press the test button during an alarm to have the unit enter silence mode. If the CO
concentration still exceeds the alarm threshold after 6 minutes, the unit will re-enter alarm state.
NOTE: When the CO alarm signal activates, move to fresh air immediately. Silence Mode only temporarily silences
the alarm and does not mean that the CO hazard has cleared.
NOTES:
1. If the smoke concentration is too high, silence mode cannot be enabled. This unit will continue to alarm until the
smoke concentration has decreased to a low level.
2. You can silence all interconnected units by pressing the Test/Silence button on one of the units. If one unit is still
alarming, it is the initiating unit (the unit that detected danger); to silence all interlinked units, you must also press
the Test/Silence button on the initiating unit.
3. The silence period will last 9 minutes unless the smoke level increases to unsafe levels.
Buzzer
The alarm will sound when there is smoke or CO present, when testing the alarm, when the battery is low, when
there is a fault, when the smoke chamber is contaminated, and when the end of life is reached.
LED Indicator
The LED indicator will flash in conjunction with the buzzer. Therefore, it will flash during the following states: when
powering on, in standby mode, during smoke or CO alarm states, when exiting an alarm state, during test mode,
when there is low battery, in silence mode, when there is a fault, when the smoke chamber is contaminated, and
05 06
when the unit is at the end of its life.
Low Battery
The LED indicator will flash yellow together with one beep every 60 seconds. The LCD displays the 'Lb' icon.
THE UNIT MUST BE DEACTIVATED (see "Deactivation of the Alarm" section) AND REPLACED AS SOON AS POSSIBLE.
If you press the test button when there is low battery, the low battery signal will temporarily cease for 10 hours.
Fault
If the core component of the product, the smoke sensor or CO sensor, fails, the product's LED will flash yellow twice
every 60 seconds, accompanied by two beeps every 60 seconds, and the screen will display Err/E03/E04. The fault
alarm cannot be silenced, and the product should be replaced immediately.
Smoke Chamber Contamination
If the core part of the smoke sensor, the smoke chamber, is contaminated by the surrounding environment,
causing abnormal operation, the product's LED will flash yellow 4 times every 60 seconds, accompanied by 4
beeps every 60 seconds, and the LCD screen will display E05. The smoke chamber contamination alarm cannot be
silenced. Please keep the area around the product clean, remove the product from the ceiling, vacuum the outside
of the device with a vacuum cleaner fitted with a soft brush attachment, and reinstall the product on the ceiling. If
the alarm persists, replace the product immediately.
End of Life
Once the maximum lifetime (10 years) is reached, the alarm will deliver 3 beeps and the LED indicator will flash
yellow 3 times every 60 seconds. This end-of-life signal can be temporarily silenced for 22 hours by pressing the test
button.
The end-of-life silence feature can only be used for a total of 30 days. After 30 days, the end-of-life signal cannot be
silenced.
NOTE: The replacement date shown on the device indicates the date when the device may no longer operate reliably.
Replace the device immediately when this date is reached. The 10-year lifetime of the alarm is based on the date of
manufacture.
CO Alarm Levels
This carbon monoxide alarm complies with UL 2034 standard: when CO concentration is below 30 PPM, the LCD
will not show the specific value; when CO concentration is between 30 and 70 PPM, the LCD will show the specific
value, but no audible or visual indicators will be triggered; when CO concentration reaches 70 PPM or above, the
device will emit audible and visual indicators within the standard-required time.
When CO concentration is below 30 PPM:
The LCD will show “CO P PM”.
NOTE: A CO concentration below 30 PPM is generally considered a normal daily fluctuation.
1. Ensure good ventilation.
2. Make sure to turn off all combustion appliances after use.
3. If the device continuously shows “CO PPM” but individuals feel unwell, everyone should immediately move
to fresh outdoor air and seek medical advice. Afterward, have a professional inspect the home’s combustion
appliances and ventilation system.
When CO concentration is between 30 and 70 PPM:
The LCD will show the CO concentration value, but no audible or visual alarm signal will be triggered.
NOTE: CO concentration has exceeded normal daily levels, and requires active investigation and reduction.
1. Immediately increase ventilation—open doors and windows, and turn on exhaust fans.
2. Check all potential sources of carbon monoxide. If it is safe to do so, turn off or temporarily stop using any fuel-
burning appliance or combustion equipment, including space heaters, furnaces, water heaters, stoves, cooktops,
ovens, dryers, kerosene heaters, gas fireplaces, and any internal combustion engines.
3. Monitor the concentration levels—if the concentration drops below 30 PPM after ventilation, normal activities
can resume, but it is recommended to maintain the related combustion equipment.
4. If the concentration remains above 30 PPM for over 30 minutes or if individuals feel unwell, everyone should
immediately move to fresh outdoor air and seek medical advice. Afterward, have a professional inspect the
home’s combustion appliances and ventilation system.
When CO concentration exceeds 70 PPM:
The LCD will show the CO concentration value, and the device will emit audible and visual indicators within the
standard-required time.
NOTE: Please refer to the section titled “If the CO Alarm Sounds”.
This device complies with UL 2034 standard and is programmed to sound an alarm at the following CO
concentrations within the periods listed:
70 ppm for 60–240 minutes,
150 ppm for 10–50 minutes,
and 400 ppm for 4–15 minutes.
When CO is detected and the alarm sounds, the CO concentration will be displayed on the LCD and a blue
backlight will be lit. The LED indicator will flash red and the alarm will issue 4 short beeps, repeating the cycle every
5.8 seconds.
WARNING
1. Any remote silencing function can only be used
within the line of sight of the alarm.
2. If there is any doubt about the cause of the alarm,
it should be assumed that the alarm was triggered
by dangerous levels of carbon monoxide, and the
07 08
residence should be evacuated.

5 How to Set Up and Interconnect Wireless Alarms
All X-SENSE Link
+
wireless interlinked alarms contain a built-in RF module that enables you to wirelessly connect
2 or more interlinked alarms and create an interlinked network. When one unit is triggered, all interconnected
alarms will sound. The X-SENSE Link
+
series contain wireless interlinked smoke alarms, wireless interlinked carbon
monoxide alarms, and wireless interlinked smoke and carbon monoxide alarms. This model is designed to be
wirelessly interlinked with other X-SENSE Link
+
alarms, but is not designed to communicate with wireless interlinked
alarms from other manufacturers.
A maximum of 18 X-SENSE safety devices may be interconnected in a multiple station arrangement. The
interconnect system should not exceed the NFPA interconnect limit of 12 smoke alarms. This smoke/CO
combination alarm must be counted as a smoke alarm when determining the number of units on an interconnect
network. With 12 alarms interconnected, it is still possible to interconnect up to a total of 6 remote signaling
devices and/or relay modules.

X-SENSE SD19-W XP0H-WN
The X-SENSE Link
+
wireless interlinked alarms in one multi-pack have already been interconnected, and the alarms
in each multi-pack have their own independent interlinked network. If you have more than one multi-pack, you
will need to connect them all to the same network. Choose one multi-pack as your base network and connect the
other multi-packs to it.
NOTE: The following instructions regarding wireless interconnection are applicable to the X-SENSE Link
+
wireless
interlinked alarms only.
How to Interconnect
1. Make sure you only work with 2 units at a time, and make sure that they are both turned on to ensure successful
connection.
NOTE: To turn on the device, attach the alarm properly to the mounting bracket and turn clockwise to lock it. To
learn how to turn on different models of wireless interlinked alarms, please refer to their specific user manuals for
more details.
2. Press the test/silence button on one of the 2 units 4 times; it will beep once and the LED will flash blue slowly,
indicating it has entered pairing mode and is waiting for a new unit to be added. Quickly press the test/silence
button on the other unit twice; it will beep once and the LED will flash blue rapidly, indicating it is searching for a
device to connect to.
3. After the search is successful and an interconnected group is created, both units will beep once and
automatically exit the interconnection mode. At this point, both units will only flash once every 60 seconds,
indicating they are in normal standby mode.
4. If you want to connect a third alarm to this group, first activate a new device according to its operating
instructions, and then quickly press the test/silence button on either of the 2 previously interconnected units 4
times. This unit will beep once, and the LED will flash blue slowly, indicating it is ready to add a new device to the
network. Next, quickly press the test/silence button on the new unit twice, and the LED will flash blue rapidly as
it searches for a network to connect to. After the third unit successfully joins the interconnected network, both
units will beep once and automatically exit the interconnection mode.
5. If you want to connect more units, simply repeat step 4. Up to 18 alarms can be interconnected this way. To
ensure that all alarms enter the same interlinked network, make sure you only work with 2 units at a time—one
unit enters the pairing mode and the other unit enters the searching mode.
6. Test the alarms according to the steps in the section “Alarm Test.”

wireless interlinked alarms in one multi-pack have already been interconnected. To create
a new network, you will first need to disconnect each alarm individually in this multi-pack to avoid having them all
join the same network.
6 Alarm Mode
X-SENSE Link
+
wireless interlinked alarms can be interconnected such that any unit that senses danger will cause all
other units in the interconnected network to alarm.
1. If the Initiating Unit Is Triggered by Smoke:
When one smoke alarm is triggered in the interconnected network, the unit will beep 3 times, paired with the LED
that flashes red every 4 seconds. Any other interconnected units will follow suit—they will beep 3 times every 4
seconds, paired with the LED flashing red and green in succession.
2. If the Initiating Unit Is Triggered by CO:
When one CO alarm is triggered in the interconnected network, the unit will beep 4 times every 5.8 seconds, paired
with the LED flashing red. Any other interconnected units in the network will follow suit—they will beep 4 times
every 5.8 seconds, paired with the LED that flashes red 4 times first, followed by the LED that flashes green once
with every beep. When the CO concentration level drops below the alarm threshold, the alarm will cease.
NOTES:
1. When one unit is triggered, other interconnected units will sound. If the smoke alarm and CO alarm are triggered
in the network at the same time, the alarm signal of the smoke alarm will take priority over that of the CO alarm.
2. This alarm has a relay function that extends the wireless interconnected network for wide detection coverage.
7 Alarm Test
Be sure to test your alarms when you turn them on for the first time, or when the group configuration has changed.
In addition to the weekly tests you should perform, it is recommended to test the alarm after returning from a long
trip or vacation.
If your X-SENSE Link
+
alarm is interconnected to other X-SENSE wireless alarms, we recommend that every
individual alarm is tested during the weekly test.

NOTE: Before installation, it is recommended to test the interconnected alarms in the rooms where you intend
to install them to ensure that they are within transmission range and that nothing will interfere with their
communication.
Installation Locations
1. Prioritize the installation of a smoke/CO alarm in the bedroom and walkways, and make sure you can hear
the alarm from all sleeping areas. In a home with several bedrooms, install an alarm in every bedroom. If you
install only one smoke alarm in your home, install the alarm near to all bedrooms where possible, and not in a
basement or furnace room.
2. Install an alarm above the stairway and on every floor of the house.
3. Smoke, heat and anything burning will spread horizontally after rising to the ceiling, so install the alarm in the
middle of the ceiling where possible. Ensure the alarm is within working distance of all corners of the room.
4. If an alarm cannot be installed in the middle of a ceiling, install at a distance of 20 inches (50 cm) away from the
corners of the room.
5. If an alarm is installed on a wall, it should be at a distance of 4–12 inches (10–30 cm) below the ceiling.
6. If the length of a room or hall is beyond 30 feet (900 cm), several alarms should be installed in the same room.
7. When the wall or ceiling is angled, the alarm needs to be installed within 3 feet (90 cm) of the highest wall or
ceiling point (measured horizontally) in the room.
8. In multi-level houses or apartments, install at least one wireless alarm on each level and keep them installed in a
straight vertical line (see diagram) with as few obstacles between each of the interconnected alarms as possible
to ensure optimal signal transmission.

27 28
If the CO Alarm Sounds
WARNING
Carbon monoxide (CO) is a colorless, odorless,
poisonous gas. You can't taste, see, or smell CO, but it
can kill in just minutes.
This alarm will sound in a 4-beep pattern if life
threatening levels of CO are detected.
If the alarm sounds:
1. Immediately evacuate all occupants from the space
and go outdoors to fresh air.
2. Call emergency responders (911 or re department)
for help; notify the building or vehicle owner, as
necessary.
More detailed information on conditions which can result in transient CO
situations, such as:
1. Excessive spillage or reverse venting of fuel burning appliances caused by:
a) 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).
b) Negative pressure differential resulting from the use of exhaust fans.
c) Simultaneous operation of several fuel-burning appliances competing for limited internal air.
d) Vent pipe connection vibrating loose from clothes dryers, furnaces, or water heaters.
e) Obstructions in or unconventional vent pipe designs which amplify the above situations.
f ) Poorly designed or maintained chimneys and/or vents.
2. Extended operation of unvented fuel-burning devices (range, oven, fireplace, etc.).
3. Temperature inversions which can trap exhaust gasses near the ground.
4. Car idling in an open or closed attached garage, or near a home.
Limitations of CO Alarms
1. CO alarms may not wake up all individuals. If children or others do not readily awaken to the sound of the CO
alarm, or if there are infants or family members with mobility limitations, make sure that someone assists them in
the event of an emergency.
2. This CO alarm will not sense carbon monoxide that does not reach the sensor. This CO alarm will only detect CO
that reaches the sensor. CO may be present in other areas. Doors or other obstructions may affect the rate at
which CO reaches the CO alarm. For this reason, if bedroom doors are usually closed at night, it is recommended
that you install a CO alarm in each bedroom and in the hallway between them.
3. CO alarms may not sense CO on another level of the house. For example, a CO alarm on the second level, near
the bedrooms, may not sense CO in the basement. For this reason, one CO alarm may not give an adequate
warning. Complete coverage is recommended by placing CO alarms on each level of the house.
4. CO alarms may not be heard. The alarm buzzer noise level is over 85 dB at a distance of 10 feet (3 m). However,
if the CO alarm is installed outside the bedroom, it may not awaken a sound sleeper or one who has recently
used drugs or has been drinking alcohol. This is especially true if the door is closed or only partially open. Even
persons who are awake may not hear the alarm horn if the sound is blocked by distance or closed doors. Noise
from traffic, stereos, radios, televisions, air conditioners, or other appliances may even prevent alert persons from
hearing the alarm horn. This CO alarm is not intended for people who are hearing impaired.
5. CO alarms are not a substitute for a smoke alarm. Although fire is a source of carbon monoxide, this CO alarm
does not sense smoke or fire. This CO alarm senses CO that may be escaping unnoticed from malfunctioning
furnaces, appliances, or other possible sources of incomplete combustion. The installation of a smoke alarm is
required for an early warning of fire.
6. CO alarms are not a substitute for life insurance. Though these CO alarms warn against increasing CO levels, we
do not warrant or imply in any way that they will protect lives from CO poisoning. Homeowners and renters must
still insure their lives.
7. CO alarms have a limited life. Although the CO alarm and all of its parts have passed many stringent tests and
are designed to be as reliable as possible, any of these parts could fail at any time. Therefore, you are strongly
recommended to test your CO alarm weekly.
8. CO alarms are not foolproof. Like all other electronic devices, CO alarms have limitations. They can only detect CO
that reaches their sensors. They may not give early warning of rising CO levels if the CO is coming from a remote
part of the house, or is at some distance from the CO alarm.
Limitations of Smoke Alarms
1. Fires where the victim is intimate with a flaming initiated fire; for example, when a person's clothes catch fire
while cooking;
2. Fires where the smoke is prevented from reaching the smoke alarm due to a closed door or other obstruction;
3. Incendiary fires where the fire grows so rapidly that an occupant's egress is blocked even with properly located
smoke alarms.
