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 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!
