Installation Instructions

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 impor- tant 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.

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 elec- tronics, 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.
