Table Top Alarm
You can also use your Kidde CO Alarm as a table top unit. Simply fol-
low the steps for removing adapter, then instead of mounting the alarm
to a wall, replace the back cover and stand the unit on a table, bed-
side stand, or chest of drawers.
Normal Operating Characteristics
When you first power up the unit, the alarm will sound briefly to let you
know the unit is receiving power and that the alarm circuit is function-
ing.
You should see three eights on the digital display, indicating the alarm
is in the start-up mode. The three eights will remain for approximately
20 seconds. You should see a blinking red dot to the lower right of the
digital display. The blinking dot indicates that the alarm is operating.
Within 20 seconds, your CO alarm will start monitoring for CO.
Note: The number will probably be zero (0). This is a normal condition
for most households and indicates that no measurable amount of CO is
being detected.
The alarm has begun monitoring the air for CO and will continue to do
so as long as it receives power.
When the alarm is unplugged or loses power and you have a good 9
volt battery installed, the alarm will automatically switch to its battery
backup mode and you will notice the following:
• After 4 minutes the digital display will show a blinking dot only – this
helps conserve the battery’s power.
• The digital display will show a number for CO only if it senses CO
while in backup mode.
• If CO is detected while on battery backup, the alarm pattern is con-
tinuous quick beeps .
Note: When AC power is restored, the alarm will automatically switch
back to normal operating mode.
