Mounting
The detector base mounts directly to 3

To mount, remove the decorative ring by rotating it in either
direction to unhook the snaps. Then, separate the ring from
the base. Install the base on the box, using the screws sup-
plied with the junction box and the appropriate slots in the
base. Replace the decorative ring on the base and rotate it in
either direction until the ring snaps in place (see Figure 1).
