Location in Your Home
In accordance with NFPA recommendations, it is recommended to install an X-Sense smoke and carbon monoxide alarm:
![]() | FIRE EXTINGUISHERS |
![]() | SMOKE ALARMS |
![]() | CARBON MONOXIDE ALARMS |
![]() | SMOKE & CO ALARMS |
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 smoke and carbon monoxide alarm:
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.
To test an individual device:
Press the Test/Silence button. The device should emit two sets of three long beeps, followed by two sets of four beeps. The LED indicator should flash red. After testing, the device will automatically return to standby mode.
To test all interconnected devices:
Press and hold the Test/Silence button on any device until you hear beeps. The initiating device should keep beeping with its LED indicator flashing red. Other interconnected devices should emit two sets of three long beeps with the LED indicator flashing red and green in sequence, then emit two sets of four beeps with the LED indicator flashing red.
The test will finish within three minutes, at which point all devices will return to standby mode.
Do not tamper with this device, as this may result in electrical shock or device malfunction.
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 simultaneously 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.
Ifa smoke alarm is triggered, you will hear and see:
Initating 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:
If a CO alarm is triggered, you will hear and see:
Initating 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:
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 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 mute 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.
