GENERAL VISUAL AND AUDIBLE INDICATOR OPERATION
Red LED Indicator: The red LED will blink in conjunction with the alarm sound. 
Therefore, the red LED will blink during a smoke alarm, a low battery mode 
chirp, a unit error mode chirp or at end of unit life.
Fault Mode Indicator: These alarms monitor strategic functions of internal 
electronics and sensors. If a problem is detected the alarm will enter a fault 
mode. If this occurs the alarm will produce a single “chirp” approximately every 
30 seconds and blink the Red LED 2-12 times. If this should occur call Kidde 
Customer service at 1-800-880-6788.
End of Unit Life Indicator: Ten years after initial power-up, this unit will 
“chirp” twice every 30 seconds to indicate that it is time to replace the alarm. 
This alarm has End of Life Hush
®
 which allows you to silence the trouble chirp for 
three days giving you extra time to replace the unit at a more convenient time.
