Smoke Alarm

Thank you for selecting our product LX-SO-729
LX-SO-729 Smoke Alarm User's Manual
The photoelectric smoke detector is designed to sense smoke that
comes into the detector chamber. It does not sense gas, heat, or
flame. This smoke detector is designed to give early warning of
developing fires by giving off the alarm sounds from its built-in alarm
horn. It can provide precious time for you and your family to escape
before a fire spreads.

►Install a smoke detector inside every bedroom.
►Install smoke detectors at both ends of a bedroom hallway if the hallway is more than 40 feet (12 meters) long.
►Install a smoke detector inside every room where one sleeps with the door partly or completely closed, since
smoke could be blocked by the closed door and a hallway alarm may not wake up the sleeper if the door is closed.
►Install basement detectors at the bottom of the basement stairwell.
►Install second-floor detectors at the top of the first-to-second floor stairwell.
►Install additional detectors in your living room, dining room, family room, attic, utility and storage rooms.
►Install smoke detectors as close to the center of the ceiling as possible. If this is not practical, put the detector
on the ceiling, no closer than 20 inches (50 cm) from any wall or corner, as shown in Figure 3.
