电磁释放器

防火门电磁释放器 (断电型)
 
防火门电磁释放器 - 断电型,是一种与普通闭门器搭配使用的释放器,在常通电的消防控制下正常工作,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,释放器工作,释放拉扣,防火门在普通闭门器的作用下关闭。


安装注意事项:安装时,拉链或拉绳应与门扇尽量保持垂直,避免卡阻。


(1)、电磁释放器可用于商场、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)。电磁释放器需长期直流DC24V供电(常开状态),接通电源后首次充电15秒内红灯亮起, 期间耗电7mA,之后耗电0.01mA几乎不消耗主机电流,当火灾发生时,该电磁释放器接收联动控制信号时立即断电释放自动脱开拉扣,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)、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。该电磁释放器适用于左门或右门,即左右通用。
 
(3)、该电磁释放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)、该断电型电磁释放器与通电型相比较时,释放关门其稳定性更高,更灵活全面。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 release device 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 releaser releases the pull button, and the fire door closes under the action of a common door closer.
 
Notes: When installing, the zipper or cord should be kept perpendicular to the door leaf to avoid sticking.
 
1. Electromagnetic releaser 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 releaser 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), the first charge for 15 seconds after the power supply, power consumption is 7mA, the red light come on, then the power consumption is 0.01mA, almost no consumption of the main current. When the fire, the electromagnetic releaser receives the linkage control signal, Immediately power off release automatically disconnect pull button, the fire door closes under the action of a common door closer. The closing door mode after power off to release is more in line with new national fire standard requirements.
 
2. 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 universal.
 
3. The electromagnetic releaser is suitable for all kinds of fire doors: steel fire doors, wooden fire doors, stainless steel fire doors, and glass fire doors.
 
4. When the power-off type is compared with the power-on type, the power-off type is more stable, more flexible. 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.
