How to Set Up and Interconnect Wireless Alarms
All X-Sense 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 wireless interconnected alarms 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 alarms, but is not designed to communicate with wireless interlinked alarms from other manufacturers.
The X-Sense 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+ Pro and 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.

2. Quickly press the test/silence button on one of the 2 units 4 times. The device will say “Searching for a new device”; it will beep once and the LED will flash blue slowly, indicating it has entered pairing mode. Quickly press the test/silence button on the other unit twice. The device will say, “Ready to connect”, the device 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 say “Connected,” then beep once and automatically exit the pairing
   mode.

4. If you want to connect a third alarm to this group, quickly press the test/silence button on either of the 2 previously interconnected units 4 times. Then quickly press the test/silence button twice on the third device.

5. To add more units, repeat step 4. Please note that simply press the test/silence button 4 times on any device in the network and twice on the device you want to add. However, for the XH02-M, you should press its pairing button located on the back, not the test/silence button on the front.

6. Test the alarms according to the steps in the section “Alarm Test.”

NOTES

1. The alarm will enter the searching mode or the pairing mode for 60 seconds with the LED flashing blue. After 60 seconds, repeat step 2 to connect the alarms. If necessary, press the Test/Silence button once while the alarm is in either the searching or pairing mode. This action will stop the LED from flashing blue and the device will say “Connection failed. Please try it again.” Afterward, the alarm will exit the pairing mode and return to normal operation.”
2. Test all wireless alarms to ensure they are interconnected before installation.
3. A maximum of 24 wireless alarms can be interconnected on the same network.
4. The model can only be interconnected with the same model and other X- Sense Link+ Pro and Link+ wireless interlinked alarms.

How to Disconnect
Quickly press the Test/Silence button 4 times, the alarm will say “Searching for a new device”, it will beep once and the LED will flash blue slowly. Then, hold down the button until it says “Disconnected, standalone device now” and beeps once more to disconnect. After disconnecting, it can be reconnected to the same network, or added to a new network.
NOTE: The X-Sense Link+ Pro 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.

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 XS0B-MR smoke alarm is interconnected to other X-Sense wireless alarms, we recommend that every individual alarm is tested during the weekly test.

NOTE: If a smoke alarm is installed in a kitchen, ensure it has an accessible silence button, and install it as far away from the stove and sink as possible to avoid false alarms.
Installation Locations

1. Prioritize the installation of an 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), you will need to install several alarms 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.

1. Drill three Ø 6.0 mm holes in the wall or ceiling, then insert three plastic anchor plugs into the holes with a hammer.
2. Attach the mounting bracket to the surface of the wall or ceiling with three screws and mount the alarm into the bracket by pushing them together and twisting the unit clockwise.
3. Test the unit by using the Test/Silence button. Ensure the unit sounds in an alarm pattern.

Alarm Mode
For devices connected to the base station:

• When an alarm is triggered, an in-app message will appear and an alarm push notification will be sent to your smartphone.
• When one alarm is triggered, all devices connected to the system and the base station will sound an alarm simultaneously.
• The base station will automatically mute after 10 minutes of continuous alarm.
• After the base station stops the alarm, all devices in the interconnected system will still alarm.
• In the case that the base station powers off and is disconnected from the network, all devices are still interconnected, so when one alarm is triggered, all will go off.
• The volume level of the base station is adjustable. The alarms and base station can be remotely muted through the app. An app push notification will be sent to your phone when the smoke drops below the alarm threshold.

1. If the Initiating Unit Is Triggered by Smoke:
   When one XS0B-MR smoke alarm is triggered in the interconnected network, the unit will beep 3 times every 4 seconds, paired with LED flashing red. Any other units will follow suit—they will beep 3 times every 4 seconds, paired with the LED flashing red and green in succession. When the smoke concentration level drops below the alarm threshold, the alarm will cease.

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 units 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. When the CO concentration level drops below the alarm threshold, the alarm will cease.

For more details, please see “LED Indicator and Audible Alarm”.

NOTES

• 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.
• If the initiating alarm is a voice alarm with location support (such as XS0B-MR), the other interconnected voice alarms with location support will also provide location information. However, if the initiating alarm is without location support, the other interconnected voice alarms with location support (such as XS0B-MR) will relay the voice alert without specifying the location.
• This alarm has a relay function that extends the wireless interconnected network for wide detection coverage.

Silence Mode
You can silence the device by pressing the test/silence button on the device or tapping the silence button in the app.
If you press the silence button during an alarm state, the device will say “Smoke alarm silenced” and a push notification will be sent to your phone (when connected to the base station). Then the unit will be in the silence mode for 9 minutes. During the silence mode, the LED flashes red 3 times every 4 seconds. After 9 minutes, the LED will flash green 3 times and the alarm will enter the normal mode.

When Connected to the Base Station
When an alarm is triggered, you can press the Silence button on the base station to silence all passive interlinked alarms except the initiating alarm. To silence the initiating alarm, simply press the test/silence button on the device. Additionally, you can tap the ”Silence All” button in the app to silence the base station and all alarms, including the initiating one.
You can tap the Locate button in the app to find the initiating alarm; all devices will stop alarming except the initiating alarm. Simply silence the initiating alarm by tapping the silence icon in the app or by pressing the test/silence button on the device.

When Not Connected to the Base Station
Simply press the test/silence button on one of the devices to silence the interconnected system, however only silencing the initiating alarm will silence all other interconnected alarms.
The initiating alarm will report the voice “Smoke alarm silenced” and all other interconnected alarms won’t.

NOTES

• 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.
• While interconnected, the initiating unit cannot be triggered again during the 9-minute silence duration. However, all other interconnected units can be triggered
  again if they detect danger during the silence mode.

1. Battery life is calculated on the current ratings in the standby mode with weekly testings. If its operation mode changes to an alarming condition, the battery life will be decreased accordingly.
2. The smoke alarm functions between 40 and 100°F (4.4 and 37.8°C). Prolonged exposure to temperatures outside of this range can reduce battery life and affect accuracy. We do not recommend operating the device outside of this range.

Maintenance

To keep your smoke alarm in good working order, follow these simple steps:

1. Verify the unit’s alarm sound and indicator are working properly by testing the unit once a week.

2. As a minimum your smoke alarm should be cleaned once every 3 months:
   Remove the unit from the ceiling and clean the alarm cover and vents with your vacuum cleaner fitted with the soft brush attachment to remove dust and dirt.

3. Never use detergents or other solvents to clean the unit.

4. Avoid spraying air fresheners, hair spray or other aerosols near the alarm.

5. Do not paint the unit. Paint will seal the vents and interfere with the sensor’s ability to detect fire.

6. Never attempt to disassemble the unit or clean inside. Doing so will void your warranty.

7. When removed, place the smoke alarm back in its proper location as soon as possible, to assure continuous protection from fire.

8. When household cleaning supplies or similar contaminants are used, the area should be ventilated.

Troubleshooting

The device is not triggered when it is tested with smoke.

| The device is not turned on.| Make sure the battery insulating film is removed. If the battery runs out, please

replace the battery.

**The smoke is not reaching the sensor properly.| The holes on the surface of the device are for the speaker and buzzer. Smoke will not be effective. The smoke needs to enter the device from the side grille in order to trigger the alarm.
| The time duration is insufficient for the device to detect**

smoke.

| Continuous smoke is necessary for the device to be triggered. When smoke reaches the smoke sensor, the device will be triggered in

about 20 seconds.

---|---|---

Insufficient smoke concentration.

| This product utilizes a photoelectric sensor, requiring sufficient smoke concentration for detection. Higher smoke levels lead to faster alarm response. Avoid

using an open flame for testing.

The alarm does not sound during a test.

| ****

The device does not turn on.

| Remove the battery insulating film from the battery compartment to turn on the device. If the battery runs out, please replace the

battery.

You don’t push the Test/Silence button

firmly.

| Make sure you have pushed the Test/Silence button firmly.

When the test button is held down, only one alarm sounds and the other interconnected alarms do not respond.

• When connected to a base station, holding down the test button only tests a single device.
• When connected to a wireless interconnected network, holding down the test button will test all devices in the network.
• When exited from the wireless interconnected network, holding down the test button only tests a single device.
• A short press on the test button will always test a single device.

**It is unclear how to judge which alarm is triggered first.**

| | Look in the app (when connected to the base station): only the initiating alarm will be displayed as being triggered, and the

other alarms will not.

Determine by the voice: All alarms in the network will report the voice with the location where the initiating one is

triggered.

Judge by the color of the LED indicator: the initiating alarm flashes red, and the other alarms alternate flashing red and green.
Press the test button: In the alarming mode, press the test/silence button on any of the devices. If all other alarms are muted, the device you pressed is the source alarm, if not, then the source alarm is the one you will hear continuing to alarm. You need to press the test/silence

button to silence the initiating alarm.
