4 Precautions for installation
Last update date June 22, 2023
When installing on the ceiling
Install the center of the residential fire alarm at a location 60 cm or more from the wall.
If there is a beam, etc., install it at least 60 cm away from it.
When installing near the outlet of an air conditioner, etc., smoke flows through the blowout wind.
Please keep it at least 1.5m away because it may not be possible to detect it effectively.
When mounting on a wall
Since the corner of the ceiling is hard to keep smoke, the center of the fire alarm for the house is located.
Install it so that it comes between 15cm and 50cm from the ceiling.
Be careful!
・When installing in a place where smoke or steam is likely to occur, such as a kitchen, avoiding places where smoke or steam directly apply.
