With urbanization and the formation of mega cities, population pressure has led to increasingly large construction plans and higher floors. Modern buildings are densely populated, and once a fire occurs, it is relatively difficult for personnel to disperse. Therefore, the active fire alarm and rescue system for high-rise buildings has become an essential component of high-rise construction.
The fire linkage system is an important component of the active fire alarm system. Generally includes fire linkage controllers, fire control room display equipment, transmission equipment, fire electrical control equipment, and emergency power supply for fire equipment. Fire electric equipment, fire linkage module, fire hydrant button, fire emergency broadcasting equipment, fire telephone and other equipment and components.
With the rapid development of electronic and computer skills, this skill has been widely applied internationally in fire alarm systems and fire rescue systems. At present, active fire alarm systems are widely used in newly constructed buildings, which detect changes in environmental parameters such as smoke, light, and temperature during a fire through corresponding detectors and transmit them to the central processing unit. After rapid analysis by the computer, it determines whether the fire is on and quickly alarms the fire situation, activating the active fire rescue system together to control the fire situation; Activate emergency broadcasting system and crowd dispersal guidance system to quickly evacuate personnel inside the building; Isolate the fire area with enclosed fireproof rolling shutter doors; Activate the active smoke exhaust system to expel toxic gases, control the fire as much as possible, reduce casualties, and minimize property damage.
The active smoke exhaust system often uses electric window openers, which are intelligent electric windows.
Electric window opener (electric window opener) is a new type of device that actively opens/closes windows, which can achieve active control of window opening/closing. Window opening machines are widely used for the active opening and closing control of windows in shopping malls, hotels, campuses, hospitals, public entertainment venues, workshops, warehouses, computer rooms, and other places, as well as the active opening and closing control of natural smoke exhaust windows and air intakes in various places.
Characteristics of electric window opener:
When reaching the direction, the microcomputer actively controls (opening or closing the window). Window opening itinerary is optional.
Being able to use doors and windows in any direction within a useful itinerary.
When it is windy and rainy, the electric window opener can automatically close doors and windows under the control of a microcomputer (requiring the installation of a company equipped wind and rain sensor).
When a fire occurs, the electric window opener can automatically open the doors and windows to the corresponding viewpoint (required to be connected to the fire protection system).
Large scale construction will use electric window openers to handle indoor air circulation and lighting, improving the overall comfort of the building. The presentation of electric window openers has solved various problems of difficulty in opening high windows during construction. In addition, through integration with building fire linkage systems, intelligent electric window openers can control all windows to open actively in the event of a fire, enhancing indoor air circulation, smoke exhaust, and reducing casualties caused by inhaling toxic smoke and suffocation.
What are the conditions for the linkage between electric window openers and fire protection systems
1. It has the function of active switching of backup power supply, and the size of its power supply is selected by the on-site system equipment to determine the A/H of the battery;
2. It has the function of actively returning the indicator signal to the fire center, which is used to determine the operating status of the electric window opener;
3. It can independently form a local fire warning system, which includes external smoke and temperature sensing interfaces;
4. Having independent passive contact points.
