Kidde KN-COSMXTR-B - Manual (Page 10)

Step 1: Installing Batteries
Batteries were not installed at the factory and must
be installed for the unit to operate! Install the three (3)
AA batteries in the back of the Smoke/CO Alarm.
• The mounting plate must be removed from the back of
the unit to install batteries. To remove, hold the
mounting plate and twist counterclockwise (left).
• The battery polarity markings
on the bottom of the battery
compartment must be adhered to.
• Batteries must be installed in the
sequence shown. If the batteries
seem difficult to install, they’re
not being installed in the proper
sequence.
• Smoke/CO Alarm will not engage to bracket unless
all three batteries are installed. Removal of any or all
batteries will render the Smoke/CO Alarm inoperative!
• After the batteries are correctly installed the unit
will beep once and the red LED light will flash. After
20-30 seconds the green LED light will flash indicating
the unit is now operational.
CAUTION: Your Smoke/CO Alarm is sealed and the
cover is NOT removable!
