Alarm Features
• Independent smoke and carbon monoxide sensors.
• The smoke alarm takes precedence when both smoke and
carbon monoxide are present.
• Alarm/voice message warning system that alerts you to 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
followed by the verbal warning message "Fire! " This pattern
is repeated until the smoke is eliminated. The red LED will
flash along with beeps.
– CARBON MONOXIDE: The alarm/voice pattern is four
short alarm beeps followed by the verbal warning message
"Warning, carbon monoxide" After four minutes the alarm/
voice pattern will sound once every minute until the unit is
reset, or the CO eliminated. The red LED will flash while in
alarm/voice mode.
– LOW BATTERY: When the batteries are low and need
replacing the red LED will flash and the unit will "chirp"
one time, followed by the warning message "Low battery"
This cycle will occur once every minute for the first hour.
After the first hour the red LED will continue to flash every
minute accompanied by only the "chirp" sound. The voice
message "Low battery" will sound once every fifteen
minutes during the chirp-only cycle. This will continue for
at least seven days.
• One "chirp" every 30 seconds is an indication that the alarm
is malfunctioning. If this occurs call the consumer hotline at
1-800-880-6788.
• Loud 85 decibel alarm
• Oversized test button for easy activation
