Cheap, good if used for 10 years

There is no coordination function with voice and other alarm devices, but it is good to use for 10 years at this price. Since the alarm sound is large, if it rings on the first floor or the second floor, it reverberates through the house. I think that a thing with a simple structure like an alarm device is good. Extra features lead to uselessness in emergency. As for the alarm of another company that I used before, say "Please replace the battery" in the 10th year, so if both batteries are replaced with batteries (1 set of batteries 3000 yen), this time " Next time I said that. There was a state that there was no alarm for a while, and I thought that it was better not to have extra functions, etc, because setting is so complicated.

There is a smoke detection formula and a heat detection formula, and this is a smoke detection formula for general use

Basically install smoke detection ceremony, but if there are many smoke in the kitchen etc and false alarm is problematic, we will set up a thermal detection formula. However, our house chose a more reliable smoke detection formula for the kitchen because we do not do much cuisine with a lot of smoke. Two months have passed, but there are no false alarms. If you get lost, please search by "fire alarm", "smoke", "heat" and search related information because it will hit.

Mounting and Strain Detection

The mounting method is not lost by screwing but because the wood screws are long, it is difficult to apply the pressure of the screw tip from the screwdriver at the beginning. Can screws be short a little more? Attaching to the ceiling Because weight is light, it is simple or you want ingenuity. The detection capability detects that it is just above the ventilator, so I moved about 1 m. I am satisfied with the detection ability.

Both wall-hanging and ceiling correspondence

Can be flexibly installed such as hitting with a nail on a wall or mounting with a hook. Although the battery is not a versatile one, it seems to have 10 years, so it looks good if you replace the body.

For replacement

Since the thing attached at the time of new construction became useless in 10 years, I purchase it for replacement, I want you to have this time for ten years. Installation was easy.

Arrived

All but the battery was set. I understood well how to install the mounting position. I do not know whether to detect it because there is no smoke, but I believe and set it up.

Mother is stir-fried without ventilator, smoke is confirmed anymore.

After all, Japanese manufacturers are the best. Unfortunately, a few days after installing this, when my mother was stir-frying a ventilator in the kitchen, smoke went up and warnings were reported. I am relieved to be able to check the operation.
