Malfunction in 4 months of use. Buzzes continuously with code 8 and green lights. Waste of money
One of the three broke down in 4 months of use. Buzzer made a continuous long buzz with both lights green and code 8. When I moved the alarm outside the house into fresh air and tested with new batteries the same issue persists. This means there is a malfunction. When I place another buzzer in the same room at yhe same moment while the faulty ine is buzzing, the second alarm makes no sound. This confirms that the buzzer broke down. I have added an image and a video. I cannot trust anymore that the other two alarms can make a correct detection in case of a real incident. Would be throwing them away.
