User Guide
4. Battery installation instructions are provided on the inside of the 
battery door.  
To ensure proper installation of the smoke alarm battery, follow 
the instructions.
5. When installing the battery, press the battery reminder finger 
down into the battery compartment and install the battery (see 
figure 5).
 CAUTION! IF THE BATTERY REMINDER FINGER IS NOT 
HELD DOWN IN THE BATTERY COMPARTMENT BY THE 
BATTERY, THE BATTERY DOOR WILL NOT CLOSE AND THE 
UNIT WILL NOT ATTACH TO THE MOUNTING BRACKET.
6. Install the alarm on the trim ring 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).
TAMPER RESIST FEATURE: To make your smoke alarm tamper 
resistant, a tamper resist feature has been provided. Activate the 
tamper resist feature by breaking off the four posts in the square 
holes in the trim ring (see figure 6). When the posts are broken 
off, the tamper resist tab on the base is allowed to engage the 
mounting bracket. Rotate the alarm onto the trim ring until you 
hear the tamper resist tab snap into place, locking the alarm on 
the trim ring. Using the tamper resist feature will help deter chil-
dren and others from removing the alarm from trim ring. NOTE: 
To remove the alarm when the tamper resist tab is engaged, press 
down on the tamper resist tab, and rotate the alarm off of the 
trim ring (see figure 6).
After installation, test your alarm by depressing and holding down 
the test button for at least 5 seconds. This should sound the alarm.
OPERATION: The smoke alarm is operating once a fresh battery is 
installed and testing is complete. When products of combustion 
are sensed, the unit sounds a loud 85db pulsating alarm until the 
air is cleared.
