User Manual
Introduction
Thank you for purchasing this X-sense hardwired combination smoke and carbon
monoxide alarm. This user manual contains important information about your
alarm installation and operation. Please read this manual carefully and save
it for future reference.
This X-sense hardwired combination smoke and carbon monoxide alarm is intended
for detecting both smoke and carbon monoxide in a residential environment. It
has a photoelectric sensor to detect large particles produced by smoldering
fires, and an electrochemical sensor to detect dangerous levels of carbon
monoxide, protecting your family from two deadly household threats in one
unit.
This device is powered via your home’s electrical system and is also equipped
with a backup battery in case the electricity fails. It complies with
regulatory requirements, including UL 217 and UL 2034 Standards, and should be
installed by a qualified technician. All installed wiring should conform to
articles 210, and 300.3B of the National Electrical Code ANSI/ NFPA 70, NFPA
72, and/or applicable codes in your local jurisdiction.
This device can work either as a single unit or be interconnected with other
X-sense AC and AC/DC alarms. Under AC power, all devices will alarm when any
single device senses smoke or CO. If the electricity fails, only the AC/DC
devices will continue to send and receive signals within the interconnected
alarm network, while AC-only devices will cease to operate. Note that AC
hardwired interconnection only works for X-sense XP04, XP05, XP06, XP04-S,
XP05-S, and XP06-S devices.

should comply with articles 210 and 300.3 (B) of the U.S. National Electrical
Code ANSI/NFPA 70, NFPA 72, and/or any other codes having jurisdiction in your
area.
Location in Your Home
In accordance with NFPA recommendations, it is recommended to install an
X-sense smoke and carbon monoxide alarm:
- On every level of your home, including finished attics and basements.
- Inside every bedroom or adjacent hallway to every sleeping area. If a room or hallway is longer than 40 feet (12 m), install a device at each end.
- Every room contains a fuel-burning appliance.
- In all rooms, hallways, and storage areas where the temperature is usually between 40–100°F (4.4–37.8°C).
Placement on a Wall or Ceiling
It is recommended that you install an alarm on the ceiling so that it can
detect the first traces of smoke when smoke rises. However, regardless of where
you install it, ensure that nothing can prevent smoke or CO from reaching the
alarm.
If you install the device on the ceiling, center it in the room, as smoke
spreads horizontally after rising to the ceiling. Make sure it is at least 20
inches (50 cm) away from the wall.
If an alarm is installed onto a wall, keep 4-12 inches (10-30 cm) below the
ceiling.
If you install the alarm on a sloped ceiling, place it between 4 inches (10 cm) and 35 inches (90 cm) from the peak. Keep the device at least 5 feet (1.5 m) from potential smoke or fume sources such as stoves, furnaces, water heaters, and space heaters.
Mobile Home Installation
In mobile homes or older houses, extreme heat and cold can spread from the
outside to the inside due to poorly insulated walls and roofing. This may
create a thermal barrier that can prevent smoke from reaching the alarm. In
this situation, install the device on an inside wall with the top edge of the
device at a minimum of 4 inches (10 cm) and a maximum of 12 inches (30 cm)
below the ceiling.
If you are unsure about the insulation quality of your home, install the alarm
on an inside wall near the bedrooms. Test the alarm before each trip and at
least once a week during use.
Locations to Avoid
Improper location can have a negative impact on device performance and may
cause false alarms. To promote accurate detection and full protection of your
home, do not install this combination of smoke and carbon monoxide alarms:
- In a garage or any area that is dusty, dirty, or greasy.
- In bathrooms, kitchens, garages, attics, in unheated areas, or near recessed ceiling areas, ceiling fans, furnaces, or furnace vents. Keep the alarm at least 3 feet (0.9 m) away horizontally from bathroom doors.
- Within 5 feet (1.5 m) of smoke sources, such as a stove.
- In extremely humid environments. Keep the unit at least 10 feet (3 m) away from baths, saunas, humidifiers, vaporizers, dishwashers, laundry rooms, or other sources of extreme humidity.
- In turbulent air, such as near ceiling fans, heat vents, air conditioner vents, or open windows, excessive airflow may prevent CO from reaching the sensors.
- Under direct sunlight.
- In dead air spaces that may prevent smoke from reaching the device.
- Near cooking appliances, dusty areas, showers, or any areas where the temperature drops below 40°F (4.4°C) or rises above 100°F (37.8°C).
Installation
This combination smoke and carbon monoxide alarm should be installed by a
qualified technician, and all wiring should be in accordance with The National
Fire Protection Association’s Standard 72 and relevant regulations or
applicable codes in your local jurisdiction. Specific requirements for this
alarm vary by state and region. Check with your local Fire Department for
current requirements in your area.
1. Get to Know Your Alarm
 Before Installation:
- This device should be installed on a standard 4-inch (10-cm) wiring junction box, or on any ceiling or wall allowed by local codes.
- An appropriate power source is a 120 V AC Single Phase, supplied from a non-switchable circuit, which is not protected by a ground fault interrupter.
- If you want this unit to function as a standalone unit, keep the insulating cap on the red line to ensure that it does not connect to other units.
- If you want to create an interconnected alarm system, ensure all interconnected devices are powered by a single circuit.
- In accordance with NFPA restrictions, up to 24 devices can be added to a single circuit, including 18 alarms and six range extenders. A maximum of 12 smoke alarms is allowed in the 18 alarms. In an interconnected system, the maximum wiring distance between the first and last device should be no more than 1000 feet (305 m).
- Interconnect devices within a single-family residence only. Interconnected devices will only work if they are wired to compatible devices and all requirements are met. Note that AC hardwired interconnection only works for X-sense XP04, XP05, XP06, XP04-S, XP05-S, and XP06-S devices.
2. Turn Off Power

beeps with the LED indicator flashing red.
The test will finish within three minutes, at which point all devices will
return to standby mode.
Important:
Do not tamper with this device, as this may result in electrical shock or
device malfunction.
Operating Instructions
If something goes wrong with your alarm, it will notify you of what’s going on
through the colored LED indicator and beeping pattern.
What to Do When an Alarm Sounds
If an alarm is triggered, all other interconnected alarms will sound
simultaneous with the initiating alarm. If the smoke alarm and CO alarm are
both triggered at the same time, the smoke alarm will take priority over the
CO alarm in terms of signaling. When an alarm sounds, the first thing to do is
identify the type of alarm. If a smoke alarm is triggered, you will hear and
see:
| Initiating Device| Other Interconnected Devices
---|---|---
Buzzer| Three beeps every four seconds
LED Indicator| Flashes red three times every four seconds| Flash red and green
in sequence every four seconds
How to respond to a smoke alarm:
- Locate the source of fire. If a fire is present, exit the house immediately.
- Do not panic. Stay calm and follow your escape plan.
- Touch doors before you open them. If the door is not hot to the touch, open it slowly. If hot, avoid it. Keep doors and windows closed unless you must escape through them.
- Cover your nose and mouth with a cloth (preferably damp). Take short, shallow breaths.
- Once outside, call the Fire Department as soon as possible.
- Never re-enter a burning building for any reason.
If a CO alarm is triggered, you will hear and see:
| Initiating Device| Other Interconnected Devices
---|---|---
Buzzer| Four beeps every 5.8 seconds
LED Indicator| Flashes red four times every 5.8 seconds| Flash red four times
and green once every 5.8 seconds
How to respond to a CO alarm:
- Call emergency services as soon as possible.
- Move outside immediately for fresh air. Make sure everyone in the house has evacuated the area. Do not re-enter the house until the air in the house has had time to recirculate and your alarms return to normal working condition. If it is impossible to move outside, stay close to an open door/window until emergency personnel arrives.
- After following steps 1–2, if your alarm alerts again within a 24-hour period, repeat steps 1–2 and call a qualified technician to investigate sources of CO from fuel-burning equipment and appliances to ensure proper operation of this equipment.
- If problems are identified during this inspection, have the device serviced immediately. For combustion devices that have not been inspected by a technician, consult the manufacturer’s instructions, or contact the manufacturer 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.
Using the Silence Function
The silence function is only intended for temporarily silencing an alarm, not
for correcting any problems. Note that you cannot silence an alarm by removing
the battery from the device or disconnecting from power. Doing so will disable
the unit and remove your protection.
To silence a smoke or CO alarm:
You can temporarily silence false alarms by pressing the Test/Silence button
on any device.
| Smoke Alarm | CO Alarm |
|---|
The silence duration for a smoke alarm is nine minutes. After that, if the
smoke concentration level reaches the alarm level again, the device will alarm
again.| The silence duration for a CO alarm is nine minutes, then it will exit
the silence mode. However, if after six minutes, the CO concentration is still
at the alarm level, the device will alarm again. If the CO concentration is
at a very dangerous level higher than 300 ppm, the device cannot
be silenced.
Note:
- To silence any interconnected smoke or CO alarm, press the Test/Silence button on the source alarm. To locate the source alarm, press the Test/Silence button on any device; if all devices are silenced except for one device, then the alarm still sounding is the initiating device. You can also locate it using the colored LED indicator with a beeping pattern. The source alarm flashes red with three long beeps every four seconds if a smoke alarm is triggered. If a CO alarm is triggered, it will flash red with four beeps every 5.8 seconds.
- When you temporarily silence one device by pressing the Test/Silence button, other interconnected devices are not silenced and will sound an alarm together if they detect smoke or CO.
To silence the low-battery warning:
If the battery level is low, the LED indicator will flash yellow once every 60
seconds, and the buzzer will beep every 60 seconds. To silence this alarm,
press the Test/Silence button on the device. The device will be temporarily
muted for 10 hours.
To silence the end-of-life signal:
When the battery is weak, the LED indicator will flash yellow three times with
three beeps every 60 seconds. Press the Test/Silence button to stop the end-
of-life signal for 22 hours. Note that this function will only work within 30
days of the expiration date.
Smoke/CO Alarm Reminder
The device will remind you of any smoke and CO alarm you may have missed. If a
smoke alarm was triggered and then returned to standby mode after the smoke
concentration decreased below the alarm level, the LED indicator will flash red
and yellow sequentially once every five seconds. If a CO alarm was triggered
and then returned to standby mode after the CO concentration decreased below
the alarm level, the LED indicator will flash red and yellow sequentially once
every 30 seconds. To erase these alarm reminders, press the Test/Silence
button. Note that the smoke/CO alarm reminder will not work if the device is
battery-powered.

- This alarm is not to be used with detector guards unless the combination has been evaluated and found suitable for that purpose.
- Constant exposure to high or low humidity levels can reduce battery life and impair performance.
CAUTION
This smoke & carbon monoxide alarm has two separate sensors that work
independently of each other.
The carbon monoxide sensor will not detect fire or any other gases, but alerts
you to the presence of carbon monoxide gas at the sensor. Carbon monoxide gas
may also be present in other areas. The smoke sensor will only indicate the
presence of smoke at the sensor. The smoke sensor is not designed to detect
gas, heat, or flames.
WARNING
-
Never ignore any alarm, as this may result in serious injury or even death.
-
The silence function will not remove any sources of danger. It is merely for convenience. Check your home safety for any potential dangers when an alarm is triggered.
Failure to do so may result in serious injuries or even death. -
Test this smoke/CO alarm once a week. If the alarm ever fails to test correctly, replace it immediately! If the alarm is not working properly, it will not alert you to a problem.
-
This product is intended for use in indoor households. 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 that may make them more sensitive to carbon monoxide should consider using devices that provide audible and visual signals for carbon monoxide concentrations under 30 ppm. For additional information on carbon monoxide or related medical conditions, contact your physician.
-
The replacement date that appears on the device is the date beyond which the device may no longer detect carbon monoxide accurately, at which point the device should be replaced.
-
This device is designed to protect individuals from the acute effects of carbon monoxide exposure. It may not fully safeguard individuals with specific medical conditions. If you have any concerns, consult a medical practitioner.
-
Do not disconnect power from an AC-powered unit to silence a false alarm. Doing so will disable the unit and remove your protection.
Smoke Alarm
Limitations of Smoke Alarms
Alarms reduce deaths resulting from home fires worldwide. However, smoke alarms
will only work when properly located, installed, and maintained, and only if
smoke reaches the alarms.
- Smoke alarms may not wake up all individuals. Make sure you create an escape plan, and you practice fire drills with all family members.
- Smoke alarms cannot work without power. If they are battery powered, they cannot work if the batteries are missing, dead, or disconnected. If the alarm is wired, it cannot work during extended power outages, as the backup battery will die. X-sense units will notify you in advance when batteries are running low so that you have time to replace them.
- Smoke will not be able to reach the smoke sensor while the dust cover is in place. The dust cover must be removed.
- Smoke alarms cannot detect fires if the smoke does not reach the alarm. For example, if a door is closed, smoke may not reach the smoke alarm. This is why you should have a smoke alarm in every bedroom and in hallways, as bedroom doors are often closed at night.
- Smoke alarms may not be heard. Although the smoke alarm is equipped with a loud buzzer measuring at 85 dB, it may not be heard if 1) people have consumed alcohol or drugs, 2) the alarm is drowned out by noise from a stereo, TV, traffic, air conditioner, or other appliances, 3) residents are hearing impaired or have high-frequency hearing loss. Special smoke alarms should be installed for the hearing impaired.
- This smoke alarm alone is not a suitable substitute for complete fire detection systems in places that house lots of people, such as flats, condominiums, hotels, guest houses, residence halls, hospitals, long-term health care facilities, nursing homes, daycare facilities, or group homes of any kind. It is also not a suitable substitute for a complete fire detection system in warehouses, industrial facilities, commercial buildings, and special-purpose non-residential buildings which require special fire detection and alarm systems. Depending on the building codes in your area, this smoke alarm may be used to provide additional protection in these facilities.
CO Alarm
CO Alarm Level
This alarm will sound an alarm when the following CO concentrations are
detected within the time periods listed:
- 70 ppm for 60–240 minutes
- 150 ppm for 10–60 minutes
- 400 ppm for 4–15 minutes
When the CO concentration reaches the alarm level, this alarm will emit four
short beeps and the LED indicator will flash red every 5.8 seconds.
CO Concentration and Symptoms
The table below shows the effects that different levels of CO can have on the
body:
| Parts per million (ppm) | Effects on adults |
|---|---|
| 100 | Slight headache, nausea, fatigue (flu-like symptoms). |
| 200 | Dizziness and headache within two or three hours. |
| 400 | Nausea, frontal headache, drowsiness, confusion, and rapid heart rate. |
Risk to life after over three hours of exposure.
800| Severe headaches, convulsions, vital organ failures. Death is possible
within two or three hours.
Limitations of CO Alarms
- The alarm may not wake up everyone in the house. If children or other people do not quickly wake up, or if you have infants or family members with limited mobility, make sure they are assisted during an emergency.
- This alarm will not detect CO that does not reach the sensor. Doors or other obstructions may prevent CO from reaching the alarm, so make sure there is at least one alarm installed in sleeping areas, where the Limitations of CO Alarms door is often closed at night.
- CO alarms may not sense CO on another level of the house. For example, a CO alarm on the second level may not sense CO in the basement. Therefore, placing CO alarms on each level of the house is recommended.
- CO alarms may not always be heard. The alarm 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 wake up a sound sleeper or someone who has recently used drugs or has been drinking alcohol. This is especially true if the door is closed or only partially open. Even people that are already awake may not hear the alarm if the sound is drowned out by distance or closed doors. Noise from traffic, stereos, radios, televisions, air conditioners, or other appliances can also prevent people from hearing the alarm. This CO alarm is not intended for people who are hearing impaired.
- CO alarms are not a substitute for life insurance. Though these CO alarms warn you of increasing CO levels, we do not warrant or imply in any way that they will protect anyone from CO poisoning. Homeowners and renters must still insure their lives.
- CO alarms have a limited life. Although the CO alarm and all of its parts have passed stringent testing and are designed to be as reliable as possible, any of these parts could fail at any time. Therefore, it is strongly recommended that you test your CO alarm weekly.
- CO alarms are not foolproof. Like all other electronic devices, CO alarms have limitations. They can only detect CO that reaches the sensor. They may not give an early warning of rising CO levels if the CO is coming from a remote part of the house or is far away from the CO alarm.
Electrical Shock Hazard
- Turn off power to the area where you want to install this unit at the circuit breaker or fuse box before installation. Failure to turn off power before installation may result in serious electrical shock, injury, or death.
- Do not restore power until all alarms are completely installed. Doing so may result in serious electrical shock, injury, or death.
- Turn off power to the area where the alarm is installed before removing it from the mounting bracket.
- Failure to turn off power first may result in serious electrical shock, injury, or death.
- If any unit in the series does not alarm, turn off power and re-check all connections. After that, if it does not alarm yet, replace it immediately.
- Attempting to disconnect the power connector from the unit while the power is on may result in electrical shock, serious injury, or death.
- Failure to meet any of the above requirements could damage the units and cause them to malfunction.
- The alarm cannot be operated from power derived from a square wave, modified square wave, or modified sine wave inverter. These types of inverters are sometimes used to supply power to structures in off-grid installations, such as solar or wind-derived power sources. These power sources produce high peak voltages that can damage the alarm.
- Never disconnect power from an AC-powered unit to stop a false alarm. Doing so will disable the unit and remove your protection. To silence an alarm, open a nearby window or fan the smoke away from the unit. The alarm will automatically reset when it returns to normal operation.
- Improper wiring of the power connector will cause damage to the alarm and may lead to a non-functioning alarm. Test the alarm to ensure proper installation.
