In case of fire, it should have self closing and signal feedback functions. （1） Advantages of fire doors In case of fire, Henan fire doors and windows can be automatically closed through the linkage control system when they are in the open shoulder state, effectively ensuring the reliable closing of fire door maintenance in the fire, so as to achieve its due role in smoke separation and fire resistance. There is no big difference between the maintenance of fire doors and the maintenance of normally closed fire doors in terms of production and basic configuration, but the door closers for the maintenance of normally closed fire doors are replaced with automatic fire release devices that are linked with the automatic fire alarm. At the same time, they can be installed with the control box produced by the manufacturer. Linkage is achieved by installing smoke detectors and smoke detectors on the left and right sides of the maintenance of fire doors, When the smoke detector detects the smoke signal and sends it to the host computer of the automatic fire alarm linkage control system, the linkage control system transmits 24v power to the fire door maintenance releaser to automatically close the fire door for maintenance. The closing or opening status of the fire door maintenance has signals fed back to the alarm host computer or control box. Class A fireproof door Price The automatic release device for fire door maintenance developed by Dong Shicong of Chengdu Huili University Research Institute can open the fire door maintenance for 0-180 degrees freely and close it smoothly, completely changing the disadvantage of inconvenient use of the normally closed fire door maintenance closer due to its large opening angle of 90 degrees, and once the fire door is closed for maintenance, the release device will not be reset, It has become a movable fire door maintenance that automatically opens, closes, opens and closes, overcoming the contradiction that normally closed fire doors must be manually closed or cannot be closed after being pushed to a certain limit (greater than 90 degrees) for maintenance; The lesson of blood proves that people who escape from a fire simply cannot close the opened fire door for maintenance due to panic and eagerness to escape.
