7. Turn on the AC power. The green AC Power On Indicator
should be lit when the alarm is operating from AC power.
8. Two labels are included with your alarm. They have important
information on what to do in case of an alarm. Add the
phone number of your emergency service provider (Fire
Department or 911) in the space provided. Place one label
next to the alarm after it is mounted, and one label near a
fresh air source such as a door or window.
9. For model KN-COSM-IB only: Pull the Battery Pull Tab (yellow
tab protruding from unit) completely out of unit. This will
automatically connect the battery.
Step 4
Testing the Alarm
CAUTION: Due to the loudness (85 decibels) of the alarm,
always stand an arms length away from the unit when
testing.
The test/reset button has four purposes. It tests the unit’s
electronics, resets the CO alarm, activates the HUSH feature, and
activates the Peak Level Memory Feature.
After installation, TEST THE UNIT’S ELECTRONICS by pressing and
releasing the test/reset button. A series of beeps will sound,
followed by the message “Fire! Fire!” then another two series of
beeps and the message “WARNING! CARBON MONOXIDE!”
followed by 4 additional short beeps.
Weekly testing is required! If at anytime it does not perform as
described, verify power is connected correctly and that the
battery doesn’t need replacing. Clean dust and other buildup off
the unit. If it still doesn’t operate properly call the Consumer
Hotline at 1-800-880-6788.
