Kidde 21026063 AC Hardwired Smoke Detector Alarm with 9V Back up and Front Load Battery Door, White

SMOKE ALARM FEATURES

• Model ADC features a False Alarm Control which, when activated, quiets unwanted alarms for up to 15 minutes.
• This smoke alarm is powered by 120V AC and a 9-volt battery back-up source. AC/DC smoke alarms offer added protection in the event of a power failure or a drained battery.
• Unique power connector prevents interconnection with incompatible smoke alarms or security systems.
• This smoke alarm may be interconnected with as many as 11 other Firex model FADC, AD and ADC smoke alarms, or as many as 6 Firex model ADH heat alarms for a total of not more than 18 interconnected devices.
• Optional tamper-resist feature can serve as a safeguard against tampering. • Unique “battery missing” lockout. The smoke alarm will not attach to the mounting bracket if a battery is not in the battery pocket.
• Improperly connected or weak battery signal. The smoke alarm will sound a short beep about once a minute if the battery is weak or improperly connected.
• Separate green and red LEDs indicate that the smoke alarm is receiving AC power, working under normal operation, in alarm, or under false alarm control.
• Loud alarm horn—85 decibels at 10 feet—sounds to alert you to an emergency.
• This alarm incorporates the internationally recognized horn signal for evacuation. During alarm mode, the horn produces three short beeps followed by a 2 second pause and then repeats. This pattern is somewhat different than the previous alarm sound, which continually beeped.
• Test button checks smoke alarm operation. Model ADC also features a False Alarm Control which, when activated, quiets unwanted alarms for up to 15 minutes.
