电磁释放器

防火门电磁门吸 - 断电式 -墙面式 
 
防火门电磁门吸(也叫电磁释放器),是一种与普通闭门器搭配使用的,在常通电的消防控制下工作的释放器,使防火门保持常开状态。当发生火灾时,消防控制中心断开电源,门吸释放,防火门在普通闭门器的作用下关闭。


(1)、电磁门吸可用于商场、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)。电磁门吸需长期直流DC24V供电(常开状态),耗电2W (约80mA),当火灾发生时,该电磁门吸接收联动控制信号时立即断电释放,防火门在普通闭门器的作用下关闭,该断电释放关门模式是更加符合国家消防新标准要求。
 
(2)、可适用于任何安装环境,体积小,吸力大,安装方便,不需改变原有防火门任何结构,可选用链条或钢绳,长短可定制。该电磁门吸适用于左门或右门,即左右通用。
 
(3)、该电磁门吸适用的防火门:钢质防火门,木质防火门,不锈钢防火门等。
 
(4)、该断电型电磁门吸人们可以现场手动释放。拉抗力大于等于900N。



综述:该断电型电磁释放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 power-off type electromagnetic door stopper is a kind of releaser used with the common closed door. Under the condition of keeping electricity and fire control, it works normally, and keeps the fire door open. When a fire occurs, the fire control center disconnects the power supply, and the door stopper releases, and the fire door closes under the action of a common door closer.
 
 
1. The door stopper 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). The electromagnetic door stopper has remote control and local release function. The (power off) releaser is connected with the fire control system, the long-term DC 24V power supply (keep power state), power consumption is 2W (80 mA), almost no consumption of the main current. When the fire, the electromagnetic door stopper receives the linkage control signal, Immediately power off release automatically, the fire door closes under the action of a common door closer. the mode of power off and release closing door is more in line with the national fire control new standard.
 
2. It can be applied to any installation environment, with small volume and large suction. It is easy to install, no need to change any structure of the original fireproof door, and accessories can be selected a chain or a steel rope, it's length can be customized. The electromagnetic releaser is suitable for left door or right door, that is, the right and left is shared.
 
3. The electromagnetic door stopper is suitable for some kinds of fire doors: steel fire doors, wooden fire doors, stainless steel fire doors.
 
4. People can release them manually. The pull resistance is more than equal to 900N.
 
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.
