Installation
Mounting
CAUTION: This unit is sealed. The cover is not removable!
• Remove the mounting plate from the back of the alarm by
holding the plate and twisting the alarm in the direction
indicated by the "OFF" arrow on the alarm cover.
• After selecting the proper smoke alarm location as
described previously, hold the mounting plate against
the selected installation location (wall or ceiling) and
mark the centre of the holes with a pencil. To ensure
aesthetic alignment of the alarm with the hallway, or
wall, the "A" line on the mounting plate should be
parallel with the hallway when ceiling mounted, or
horizontal when wall mounted (Image 3A and 3B). Drill
a hole through the pencil marks and use the enclosed
screws and anchors to secure the mounting plate. Use
a 3/16" drill bit for the screw anchor holes.
• Press the battery reminder tab down into the battery
compartment while inserting the battery (Image 3E).
CAUTION: If the battery reminder tab is not held down in the
battery compartment by the battery, the unit will not attach to the
mounting plate.
• Alignment marks are provided on the edge of the
mounting plate and the alarm. After installing the
mounting plate, place the alarm onto the mounting plate,
making sure the alignment marks are lined up. Twist the
alarm in the direction indicated by the "ON" arrow on
the alarm cover (Image 3D) until it locks in place.
