Your detector emits three repetitive beeps every 45 seconds or so?

Three repetitive beeps approximately every 45 seconds indicate that your detector has detected a fault in its smoke sensor.

The following test procedure should be followed first to clean and test the detector:

1. Remove the detector from its base (1/4 turn to the left).
2. Clean the detector for 1 minute with the brush tip of a connected vacuum cleaner to remove any dust that may have accumulated and interfered with the product's operation.
3. Check the operation of the detector. Place the product on a table and press the central button for at least 3 seconds:

Case n°1: If the detector emits an audible alarm signal and the red LED flashes, the detector is functional and must be reinstalled on its mounting base.

Case n°2: If the detector does not ring and the red LED flashes, the battery is low and the detector must be replaced.
For detectors manufactured between 2014 and 2015 (date of manufacture indicated on the back of the detector), the discharged battery is not covered under the 10-year warranty. The conditions of application of the 10-year warranty are clearly indicated in the user manual supplied with the detector.

Case n°3: If the detector does not sound and the red LED does not flash: wait 2 minutes. If the detector emits 3 consecutive beeps every 40 seconds, then the detector has a sensor fault, and the product must be replaced. Check if the detector is eligible for the "Product Warranty". If the detector does not beep, then the battery is empty and the detector must be replaced.
