Double alarm: temperature and smoke
Notice:
Due to air traffic control, there is no battery inside the product.
1. Temperature alarm function:
When the fire just occurred, the temperature began to rise and the product’s temperature alarm function was activated. Start the alarm. (There is no smoke or less smoke generated at this time)
2. Smoke alarm function:
After 5 minutes of fire, a large amount of smoke began to be generated. If the ambient temperature is not very high, the smoke alarm function of the product will start and the alarm will start.
3. Therefore, when the fire has just occurred, the temperature alarm function of the product will start 3-5 minutes earlier than the smoke alarm function, giving you a warning.
Allows you to escape the fire scene earlier 3-5 minutes before the smoke alarm function starts.
4. At the same time, the product has a dual alarm function.
Let you have two chances to escape from the fire scene.

El detector funciona pero no sé conecta con mi alarma. El artículo y la descripción es correcta pero son inútiles para mi
Приобрел с купонами за 300 руб. Один из самых удачных вариантов. Доволен: реагирует довольно быстро на задымления. Слева такой же марки, но изза отсутствия нормальных отверстий туповат, в закрытый гараж на самой верхатуре сойдет, дома нет. Справо дорогой...и так я и не понял как сиё работает правильно.... около 1 т.р. но работа непонятна... Этот купленный рекомендую! За 300 самое то! Батарейки Кроны 9в нет в комплекте.
TOP ! VERY GOOD SHOP. SERIOUS SELLER !
Датчик рабочий. Реагирует на дым очень бысто, много дыма не надо, что бы сработал. Доставка в Украину новой почтой. Для питания требуется крона. (в комплект не входит)
Зроблено акуратно. Працює чітко, реагує навіть на димок від сірника. Рекомендую.
реагирует на дым, тепло. не стоит закрывать крышку без батарейки, торчит какой-то стопор, мешает открыть обратно, надо отгибать крышку в его месте. с батареей стопор утоплен и не мешает. см.фото
So far, so good. Of course it is hard to rate a smoke detector unless you have a fire. This unit replaced a First Alert unit that was only three years old that often sounded a false alarm, or was too sensitive to standard cooking fume. This unit was very easy to mount to the ceiling, probably less than three minutes once I got the stepladder and drill to the desired location. This unit is a little smaller than the First Alert and does not have the same footprint on the ceiling, so if the ceiling had been painted a different color you might want to use a little touch up paint around the base. Hope the battery lasts long. One thought about the smaller size of this unit. As mentioned, I had frequent false alarms with my previous First Alert where I could barely reach the unit to silence it while on my tippy toes. This unit, being smaller, I might not be able to reach it without a stool or chair to stand on.
All works good,he puted even battery inside ,came packed very good thank u
