With these steps, you can connect the smoke detectors to each other:

Step 1: Activating pairing mode on the main detector
Choose one smoke detector as the primary detector (the main detector). Follow these steps to activate pairing mode:

• Press the button 3 times briefly.
• Wait 1 second.
• Then hold the button for 1 second.
  
  

The green light will flash for 1 second and then turn off. This means the main detector is ready to pair with other detectors.

Step 2: Pairing other detectors
You have 1 minute to pair the other smoke detectors. Do this as follows:

• Set the main detector aside.
• Take one of the other smoke detectors.
• Press the button on this smoke detector 2 times briefly.
• Wait 1 second and then hold the button for 1 second.

The smoke detector will show a green light and beep briefly to indicate the pairing is successful.

Step 3: Turning off pairing mode on the main detector
When all smoke detectors are paired, turn off pairing mode on the main detector:

• Press the button on the main detector 3 times briefly.

The smoke detectors are now connected to each other.
