• 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 (Image 3D). This
ratcheting function allows for aesthetic alignment.
Note: The alarm will attach to the mounting plate in
4 positions (every 90 degrees). When wall mounting, make
sure the battery door is at the bottom of the unit (Image 3C).
Battery
This unit will not function without a properly installed
battery, and is equipped with a battery lockout feature
which prevents the battery door from closing if a battery is
not installed correctly. See Maintenance section for
additional information concerning battery installation.
• For initial installation a pre-installed 9 V battery is
included with a battery pull tab that allows for easy
connection. Simply pull the tab out, and the battery is
connected! See Maintenance for additional information
concerning battery installation.
• Pull the Battery Pull Tab (yellow tab protruding from
the unit) completely out of the unit. This will
automatically connect the battery.
Testing
• Test the unit to ensure proper operation by pressing the
Test button.
CAUTION: Due to the loudness (85 decibels) of the alarm, always
stand an arms-length away from the unit when testing.
The smoke alarm is operating once a fresh battery is installed
and testing is complete. When the smoke alarm ionization
sensor chamber senses products of combustion, the horn will
sound a loud (85db) alarm until the sensing chamber is
cleared of smoke particles.
