Features

•Loud 85 decibel alarm.

•Permanent independent smoke and carbon monoxide sensors.

•Smoke alarm takes precedence when both smoke and carbon monoxide are present.

•Powered by 120V AC (60 Hz, 25 mA max) wire-in connector. Model KN-COSM-IB is also equipped with a 9V battery back- up.

•Model KN-COSM-IB is equipped with Battery Pull Tab that allows for easy battery connection. Simply pull tab out, and battery is connected!

•Interconnectable to other Kidde/Nighthawk brand smoke and CO alarms (see page 16 for details).

•Alarm/Voice message warning system that alerts you of the following conditions in the manner described below, thus eliminating any confusion over which alarm is sounding:

FIRE: The alarm/voice pattern is three long alarm beeps fol- lowed by the verbal warning message “FIRE! FIRE!” This pat- tern is repeated until the smoke is eliminated. The red LED light will flash while in alarm/voice mode.

CARBON MONOXIDE: The alarm/voice pattern is four short alarm beeps followed by the verbal warning message “WARNING! CARBON MONOXIDE!". This continues until the unit is reset or the CO eliminated. While powered by battery only, after four minutes the alarm/voice pattern will sound once every minute. The red Light Emitting Diode (LED) light will flash while in alarm/voice mode.

LOW BATTERY(model KN-COSM-IB only): When the bat- teries are low and need replacing the red LED light will flash and the unit will “chirp” one time, followed by the warning message “LOW BATTERY.” This cycle will occur once every minute and will continue for at least seven days.
