在我們的日常生活中，經常可以看到防火門。其耐火性和隔熱性能能有效防止火災蔓延，為人員提供疏散時間。它是消防設備里面不可缺少的設備之一，所以防火門是開著好還是關著好呢？那就讓
濟南防火卷簾門安裝維修人員來去了解一下這個問題吧。
In our daily life, we often see fire doors. Its fire resistance and thermal insulation performance can effectively prevent fire spread and provide evacuation time for personnel. It is one of the indispensable equipment in the fire fighting equipment, so is it better to open or close the fire door? Let the installation and maintenance personnel of Jinan fireproof rolling shutter door know about this problem.
這要看使用防火門的類型，通常采用防火門可以分為常閉式防火門和常開式防火門。
This depends on the type of fire doors used. Generally, fire doors can be divided into normally closed fire doors and normally open fire doors.
1、防火門通常安裝在人口眾多的地方，如學校、購物中心、醫院等。因為這些地方的人經常要在樓梯里進出，如果要安裝經常關閉的防火門，肯定會很不方便。
1. Fire doors are usually installed in places with large populations, such as schools, shopping centers, hospitals, etc. Because people in these places often have to go in and out of the stairs, it would be very inconvenient to install fire doors that are often closed.
而且經常開關防火門也容易損壞，隨著時間的推移不能起到防火的作用。所以這些地方通常都安裝著打開的防火門，防火門通常是打開的狀態，所以人們進出都會非常方便。當發生火災時，監視器發出的報警信號可用于關閉防火門，從而隔離煙霧和火災。
In addition, the fire door is also easy to be damaged by frequent opening and closing, and cannot play a role in fire prevention as time goes by. So these places are usually equipped with open fire doors, which are usually open, so people will be very convenient to enter and exit. In case of fire, the alarm signal sent by the monitor can be used to close the fire door, thus isolating smoke and fire.
2、常閉式防火門我們通常可以將其安裝在人很少的地方。它在企業正常情況和火災事故發生的時候他們都是處于關閉的狀態，如果人想要從這邊走動則需要手動推開。
2. Normally closed fire doors can be installed in places with few people. It is closed in the normal situation of the enterprise and in the event of fire accident. If people want to move from here, they need to push it away manually.
通常關閉的防火門有防止火災蔓延的效果，這種門窗通常與監控系統一起使用，因為許多火災案例是由于經常關閉的防火門是打開的。
Normally closed fire doors have the effect of preventing fire spread. Such doors and windows are usually used with the monitoring system, because many fire cases are caused by the fire doors that are often closed being opened.
一旦常閉式防火門處于一個長期打開的狀態，發生火災的時候我們就很容易蔓延到其他樓梯間，起不到防火的作用。并且防火門的門磁開關可以檢測到門的狀態，因此需要有人將防火門長時間被打開的時候，門磁開關就會導致發出控制信號，報警系統提醒以及人們生活進行關門處理。
Once the normally closed fire door is in a long-term open state, it is easy for us to spread to other staircases in case of fire, and can not play the role of fire prevention. And the door magnetic switch of the fire door can detect the status of the door, so when someone needs to open the fire door for a long time, the door magnetic switch will cause a control signal to be sent, the alarm system will remind and people's life will be closed.
