Installation
• Install the alarm on the mounting plate and rotate
the alarm in the direction of the “ON” arrow on the
cover until the alarm ratchets into place (this
ratcheting function allows for aesthetic alignment).
Note: The
alarm will mount to the bracket in 4
positions (every 90 degrees).
• Turn on the AC power.
The green AC Power On
Indicator should be lit when the alarm is operating
from AC power.
• For model KN-COSM-IBCA only, pull the Battery
Pull Tab (yellow tab protruding from unit)
completely out of unit.
This will automatically
connect the battery.
Testing
CAUTION: Due to the loudness (85 decibels) of the
alarm, always stand an arms length away from the unit
when testing.
The Test/Reset/Hush
®
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/Hush
®
button.
A series of
beeps will sound, followed by the message,
"Fire! Feu!"
then another series of beeps and the
message,
"Carbon Monoxide! Monoxyde de carbone!"
followed by 4 additional short beeps.
Weekly testing is required!
If at anytime it does not
perform as described, verify that the power is
connected correctly and that the battery is fresh.
Clean
any dust or other buildup on the unit. If it still does
not operate properly, call the Product Support Line at
1-800-880-6788.
