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.

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 bat-
tery 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.
