Alerts: smoke, tamper, low battery
Operating temperature: -26°C ~ +80°C
Battery installation
Rotate clockwise the bracket on the back of the
detector, take it out and install the two AAA 1.5V
alkaline batteries (included).
Detector installation
We recommend installing the smoke detector on
the ceiling, because the smoke first rises to the
ceiling and then spreads throughout the room.
Keep at least 30cm distance from lights or
decorations, and at least 15cm away from walls and
corners.
