支臂液压-温电双控-电磁释放闭门器（通电式）
 
防火门温电双控-通电型-电磁释放闭门器，又叫电动闭门器、消防联动闭门器。它是一种无须普通闭门器搭配使用的，仅依靠自身液压缓冲功能来关门的闭门器。在平时，该电动闭门器是无源的（即不通电），防火门是常开状态，不消耗能源，使防火门保持常开状态。当发生火灾时，在接收消防联动系统控制信号（DC 24V，0.8A ，0.1秒）或温度达到68±5℃ 时，自行关闭防火门，并提供反馈信号给控制室，并立即恢复到不通电状态，人们也可以现场手动释放关闭防火门（即常闭状态）。

 
(1)、电动闭门器、消防联动闭门器、电磁释放闭门器可用于商场、超市、酒店、写字楼、医院、学校、娱乐场所等人流较大或者使用频繁的公共场所（疏散走道、楼梯间、前室）。
 
(2)、安装方便，在30-180º内可任意手动开关防火门。该电动闭门器是带缓冲功能，且能进行二级调速，保证防火门平稳关闭。该闭门器适用于左门或右门，即左右通用。
 
(3)、该电动闭门器、消防联动闭门器、电磁释放闭门器适用各种材质的防火门：钢质防火门，木质防火门，不锈钢防火门，玻璃防火门。
 
(4)、平时无源（不占用消防电源），瞬间供电释放关门。人们可以现场手动释放。关闭力矩30N.M。

 
综述：该通电型电磁释放闭门器是特别适合于大型新建项目，平时不抢占消防电源，后期使用无功耗；改造项目可直接并入防排烟系统、警铃、应急照明系统，布线成本极低。

The temperature and electricity double control, power-on type, electromagnetic release door closer is a door closer which only needs to rely on its own hydraulic buffering function to close door without using common door closer. At ordinary times, the electromagnetic release door closer is connected with the fire control system, it don't need power supply, the fire door is kept open. When the fire occurs, the fire fighting linkage control center sends a signal (power supply: DC 24V, 0.8A, 0.1 seconds),or the temperature is 68ºC±5 ºC, the door closer is release, the fire door is closed automatically, and provide feedback signal to control room, and immediately return to the state of no electricity. People can also manually release the door closer to close the fire door (that is,door is closed state).
 
1. Electromagnetic release door closer can be used in the public places of dense flow of people or use frequent. such as: shopping malls, supermarkets, hotels, office buildings, hospitals, schools, entertainment places etc. (evacuation aisles, stairways, front rooms).
 
2. It is easy to install, In 30-180 degree angle, people can manually open or close the fire doors. The electric door closer is equipped with buffering function, and it can carry out two stage speed regulation to ensure that the fire door is shut down smoothly. The electromagnetic release door closer is suitable for left door or right door, that is, the right and left is shared.
 
3. The electromagnetic release door closer is suitable for all kinds of fire doors: steel fire doors, wooden fire doors, stainless steel fire doors, and glass fire doors.
 
4. In peace time, it is passive (without occupying fire power), instantly input power to release and close door. People can release them manually. Closing door's moment is 30N.M.
 
Summary: The electromagnetic releaser is especially suitable for large new projects. At ordinary times, it does not occupy the fire power supply, and has no power consumption in the later period. The renovation project can be directly incorporated into the smoke control system, the alarm bell and the emergency lighting system, and the wiring cost is very low.
