Help CenterWhen attempting to add a second motion sensor to your Gen 2 alarm panel, you may see the following message: “Duplicate Paired Accessories”
Why this Happens
This occurs most often when adding a second PIR motion sensor. Because a previously paired PIR is still active and detecting infrared signals, the alarm panel may receive signals from the first sensor while trying to pair the second one. This causes the panel to interpret both sensors as the same device, resulting in a duplicate pairing error.
To resolve the duplicate pairing issue with your PIR motion sensors and the alarm panel, follow these steps:
- Remove all PIR motion sensors from the alarm panel.
-
Power off all PIR motion sensors.
Note: Removing the back cover of a motion sensor may trigger the alarm panel because doing so activates the built-in tamper switch. The tamper switch is located under the sensor cover. You can also temporarily disable the local alarm and siren from the alarm panel.
Remember to re-enable the local and Siren alarm.
- Turn on and pair each PIR motion sensor one at a time.
After pairing the first sensor, power it off before pairing the next one. This prevents the panel from receiving overlapping infrared signals. - After pairing each sensor, check the alarm panel to confirm the sensors are paired.
You should see each motion sensor listed on the panel. - Once all motion sensors are successfully paired, power them all back on.
- Test each sensor individually to ensure they are functioning correctly.
By following these steps, you should be able to resolve the duplicate pairing issue with your PIR motion sensors and the alarm panel.
Additional Notes
-
In rare cases, this “duplicate” error can occur if two sensors share the same serial number. Make sure each sensor has a unique serial number to avoid this issue.
