What factors should Fire Electric Window Opener consider
Publish Time: 2024-08-17
1、 Performance and Functionality
Window opening speed
When a fire occurs, the rapid accumulation of smoke and heat requires the window opener to open the window at an extremely fast speed, ideally within seconds, in order to gain valuable escape and rescue time. Slow speed may cause smoke to be unable to be expelled in a timely manner, increasing the danger.
For example, for densely populated places such as shopping malls, theaters, etc., a window opening speed of 0.2-0.5 meters per second may be more appropriate.
Window opening force
It needs to be sufficient to overcome the weight of the window itself, sealing resistance, and possible external wind pressure. Different types and sizes of windows require different forces. For example, large french window may require greater driving force.
For heavier fire-resistant windows, it may be necessary to equip motors with higher torque output to ensure effective window opening.
Travel range
Ensure that the windows can be fully opened to the specified maximum angle to achieve optimal ventilation. If the itinerary is insufficient and the angle of window opening is limited, it may affect the efficiency of smoke and heat dissipation.
For example, some building codes require windows to open at least 70-90 degrees during a fire, and the travel design of window openers should meet this requirement.
Synchronicity
If it is a system with multiple windows linked together, it is necessary to ensure the synchronization of the actions of each window opener, so that the windows can be opened simultaneously, avoiding the situation where some windows are open while others are not, which affects the overall ventilation effect.
This requires precise control systems and good mechanical transmission design.
2、 Safety and reliability
High temperature resistance capability
In the high-temperature environment of a fire (usually up to several hundred degrees Celsius), all components of the window opener, including the motor, wires, control module, housing, etc., should be able to maintain normal function without deformation, melting, or short circuit faults.
For example, using high-temperature resistant special wires and fire-resistant plastic or metal shell materials.
Fire protection level
It should meet relevant fire prevention standards and protection levels, such as IP54 and above, to prevent dust and water from entering and ensure stable operation in harsh environments.
For window openers exposed to outdoor environments, higher protection levels such as IP65 or IP67 may be necessary.
Emergency power supply
Equipped with reliable backup power sources, such as batteries, which can automatically switch and supply power to the window opener in the event of a fire interruption in the main power supply. The capacity of the backup power supply should be sufficient to support the window opener to complete the entire window opening action and maintain a certain margin.
At the same time, the backup power supply should be regularly inspected and maintained to ensure its normal operation in emergency situations.
Fault alarm and monitoring
Equipped with self diagnosis and fault alarm functions, it can monitor the working status in real time. Once abnormalities occur, such as motor faults, circuit problems, etc., it can promptly issue alarms and transmit fault information to the fire control center.
For example, monitoring the current, voltage, and operational status of mechanical components through sensors.
Mechanical strength and stability
The structural design should have sufficient mechanical strength to withstand the impact and vibration that may occur during a fire, as well as the reaction force of the window during opening, and maintain stability without falling off.
Adopting sturdy installation brackets and connectors, and undergoing rigorous mechanical calculations and testing.
3、 Control and linkage
Integration with fire protection system
It can seamlessly integrate with fire alarm systems, smoke detection systems, automatic fire extinguishing systems, etc. to achieve automatic control. When receiving a fire signal, immediately initiate the window opening action without manual intervention.
Adhere to unified communication protocols and interface standards, such as Modbus, BACnet, etc., to ensure compatibility and accuracy of data transmission.
Manual control function
In addition to automatic control, manual control devices such as emergency buttons or handles should also be provided for manual operation in case of automatic system failure or special circumstances.
The manual control device should be located in a clear and easy to operate position, with clear identification and instructions.
Remote control capability
Support remote monitoring and control through network or wireless communication, making it convenient for firefighters to operate and monitor the status of window openers outside the site.
Adopting encrypted communication methods to ensure the secure transmission of control signals.
4、 Installation and maintenance
Installation convenience
The design should consider the ease of installation and minimize damage and renovation to the building structure. The installation process should comply with relevant building codes and safety standards.
For example, adopting standardized installation brackets and fixing methods to adapt to different types of window and wall structures.
Maintenance and upkeep
Easy to perform daily maintenance and regular inspections, including cleaning, component replacement, performance testing, etc. Maintenance operations should be simple and clear, without the need for complex tools or professional skills.
Develop detailed maintenance plans and operating procedures to ensure that the window opener is always in good working condition.
service life
Select high-quality materials and components, undergo rigorous durability testing to ensure a long service life, and reduce replacement and maintenance costs.
Generally speaking, the service life of fire electric window openers should be 5-10 years or more.
