Fire doors and automatic fire extinguishing systems-Global supplier

Xi'an Jiaotong University Science and Technology Park, Yangzhou Economic and Technological Development Zone, Jiangsu Province

The fire extinguishing equipment for cable tunnels mainly includes fire doors and automatic fire extinguishers. Fire doors can be linked with distributed fiber optic temperature measurement systems, fire monitoring and alarm systems, video surveillance systems, etc. When a fire occurs, the fire doors at both ends can be automatically closed to prevent the spread of fire. Automatic dry powder fire extinguishers can automatically eject dry powder fire extinguishing agents when a fire occurs, achieving automatic fire extinguishing function and effectively extinguishing or preventing the spread of fire in the early stages of the fire.

Fire door monitoring system

The fire door monitoring system consists of a fire door controller, a fire door monitoring module, a fire door relay, an electric door closer, and other components. Its design complies with the requirements of standards and specifications such as GB50116-2013, GB29364-2012, GB50016-2014, etc.

Set up fire detectors and manual fire alarm buttons as linkage closing control devices for normally open fire doors;

◆ Manual fire alarm button setting telephone jack;

When a fire occurs, the fire door controller can be linked to close the normally open fire door;

The fire door controller or fire linkage controller can be linked to ventilation equipment and automatic fire extinguishing equipment;

The opening, closing, and malfunction status of each fire door can be fed back to the fire door controller;

The system is networked through a non-polar two-wire system using the M-BUS protocol, making construction and networking simple.

Automatic fire extinguisher

The ultra-fine dry powder fire extinguishing device has electronic control or temperature control start function, with various control modes. It can be linked with fire alarm devices such as smoke detectors, fiber optic temperature measurement systems, and sound and light alarms. It can also be automatically activated based on temperature, and can be manually activated in emergency situations. This device has the following advantages:

◆ Network management methods can be selected for better linkage performance;

◆ Non network management can also be selected, and the controller and automatic fire extinguishing device are connected by wires for easy installation;

A single controller and electromagnetic driver can simultaneously manage 1-100 sets of automatic fire extinguishing devices;

The start-up time of the automatic fire extinguishing device in the same defense zone is less than 0.2 seconds, and the overall start-up time is less than 0.6 seconds;

◆ Startup methods: linkage startup, temperature control startup, manual startup.
