Aico Ei261DENRC - Manual (Page 30)

ppm CO and 8 flashes, for 300 ppm CO). When the Test/Hush button is
pressed, the red light flashes (as per Table B on page 8) to indicate the
previous CO alarm level detected. The memory is cleared by holding down
the Test/Hush button until the red light stops flashing.

13. TROUBLESHOOTING
1. ALARM DOES NOT WORK WHEN THE TEST BUTTON IS PRESSED:
- Check that the green mains power light is on. If it is off check the wiring, fuse, circuit breakers etc.
- Hold the Test/Hush button down for at least 5 seconds.
2. ALARM BEEPS AND AMBER LIGHT FLASHES EVERY 40 SECONDS:
- If the alarm beeps and the amber fault light flashes every 40 seconds, the CO sensor is probably
defective.
