FAQ's and Troubleshooting


How do I program and link OneLink Wireless alarms?


AA Battery Installation1. Insert batteries (two AA batteries). Alarm Will Say: “Welcome, First Alert Smoke Alarm.” “No location programmed” if first time or “[Location, example: “Basement”] location programmed” when changing batteries. “To select location, press and hold test button now.”

2. Press & Hold Test Button if you would like to program the location or change the location of the Alarm. Release button after Alarm responds. Alarm Will Say: “To save location, press and hold test button after location is heard.” Alarm will speak list of locations.

3. After you hear the location of where you are placing the Alarm, Press & Hold the Test Button. Alarm Will Say: “[Location, example: “Basement”] location saved.” If no location is chosen: “No location saved.” Your Alarm has now been programmed for the location of your choice.



NOTE: Steps 1 through 3 below need to be completed within two minutes. If more than two minutes pass, the Green power LED will stop blinking. Simply open the battery drawer of the second Alarm and repeat steps 1 through 3.


1. Insert the batteries into the battery drawer of the next Alarm. DO NOT CLOSE THE DRAWER.

2. Press and hold the test button and then close the battery drawer.

3. Once you hear the unit chirp, release the test button. The Green power LED will start to blink rapidly indicating the ONELINK® Alarm is waiting for program data from one of the other existing setup ONELINK® Alarms.

4. Press and hold the test button on the first Alarm, until the second Alarm chirps and its Green power LED stops blinking. Then release the test button.

5. You will now be prompted to set the Alarm's location. Follow the directions given by the Alarm.

6. Repeat steps 1-6 for additional ONELINK® Alarms. You have now successfully linked your new ONELINK® Alarms. To add additional Alarms at a later time, follow steps 1 through 6.
