To ensure your Alecto COA1910 Carbon Monoxide Detector is working correctly, regular testing is essential. According to the user manual, it is advisable to test your detector at least once a month under normal conditions. The testing procedure is straightforward: First, press the "TEST" button on your Alecto COA1910. The "POWER," "FAULT," and "ALARM" LEDs should illuminate. Next, the detector will emit 5 beeps within 10 seconds, and the red "ALARM" will light up. If the detector encounters an error during the test, the yellow "FAULT" LED will flash twice, accompanied by two beeps per minute. Consistent adherence to this testing protocol helps ensure your Alecto COA1910 is providing reliable protection against carbon monoxide.
