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 contains wireless interlinked smoke alarms, wireless interlinked carbon monoxide alarms, and wireless interlinked combination 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. 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 SD19-W/SD20-W, attach the alarm 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 manual for more details.

  2. Quickly press the test/silence button on one of the 2 units 4 times; it will beep once and the red LED will flash 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 red LED will flash 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 in 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 red LED will flash 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 red LED will flash 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 24 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”.

NOTES

  1. The alarm will enter the searching mode or the pairing mode for 60 seconds with the red LED flashing. After 60 seconds, repeat step 2 to connect the alarms. If needed, press the test/silence button once while the alarm is in the searching mode or the pairing mode, and the red LED will stop flashing and the alarm will quit the pairing mode to enter normal status.
  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 other X-Sense Link+ wireless interlinked alarms.

How to Disconnect
Quickly press the test/silence button 4 times; the smoke alarm will beep once. Then, hold down the button until it 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 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
The smoke alarm must be properly attached to the mounting bracket before it can be tested; otherwise, it will not turn on. Be sure to test your smoke 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+ SD19-W/SD20-W is interconnected to other wireless smoke alarms, we recommend that every individual smoke alarm is tested during the weekly test.

---|---|---

NOTE: The test function accurately tests the alarm’s smoke-sensing circuit without the need to test with smoke. If your smoke alarm fails to emit an audible test signal, refer to the troubleshooting guide at the end of this manual immediately. Never use an open flame to test this device.

Installation Positioning

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.

  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 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 that the alarm is installed at a minimum distance away from corner.
  4. If an alarm cannot be installed in the middle of a ceiling, install it at a distance of 20 inches (50 cm) away from the corners of the room.
  5. If an alarm is installed onto a wall, a distance of 4-12 inches (10-30 cm) should be kept 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 smoke 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.

Locations to Avoid:

  1. Near large metal surfaces and/or where there are lots of cables/wires that can cause interference.
  2. Near fluorescent lamps, amateur radios, electrical equipment, or other units that may transmit an RF signal, as this electronic “noise” can cause false alarms.

WARNING

  1. THIS ALARM SHOULD BE INSTALLED BY A COMPETENT PERSON.
  2. ALARMS SHOULD NOT BE USED AS A SUBSTITUTE FOR PROPER INSTALLATION, USE AND MAINTENANCE OF FUEL BURNING APPLIANCES INCLUDING APPROPRIATE VENTILATION AND EXHAUST SYSTEMS.
  3. TO PREVENT INJURY, THIS DEVICE SHOULD BE SECURELY ATTACHED TO THE CEILING OR WALL IN ACCORDANCE WITH THE INSTALLATION INSTRUCTIONS.
  4. BATTERIES SHOULD NOT BE EXPOSED TO EXCESSIVE HEAT SUCH AS DIRECT SUNLIGHT, FIRE, ETC.

Installation Method

Before installation, we recommend that you test the interconnected smoke alarms in the rooms where you plan on installing them to ensure they are within range of each other and that nothing will interfere with their communication.

  1. Use the mounting bracket to mark the screw holes on the ceiling or the wall.
  2. Drill holes at the 2 marks using an appropriately-sized drill bit. Insert the anchor plugs and screw the mounting bracket using the screws provided.
  3. Attach the alarm to the mounting bracket and turn clockwise to lock the alarm.
  4. Test the smoke alarm according to the steps in the section “Alarm Test”.

NOTE: If the mounting bracket is not attached to the alarm, be sure to hold down the activation button on the back of the alarm to turn it on while testing and connecting. Otherwise, it will not turn on.

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.
