This two-part, accessible smoke detection system consists of: (1) Smoke detectors on the
ceiling throughout the home or building, and (2) a wall device that fits under your hand, posi-
tioned at a convenient height. This device communicates with the ceiling units and contains
the battery; no climbing to the ceiling is needed. To ensure that the system works, lay your
hand over the wall device and watch for a green glow. The wall device provides intuitive
interaction essential during emergencies. If smoke is detected, an alarm sounds and the wall
device glows red and displays a message indicating the location. To prevent false alarms in
the kitchen, however, the warning process happens in two stages: With a little smoke, the wall
device glows yellow and a soft alarm sounds. Cancel the alarm by holding your palm over the
device. If the smoke increases, the device glows red and a loud alarm sounds.
