Especially in crowded places, installing smoke detectors is essential. With the continuous development of new technologies such as artificial intelligence, 5G, big data, and cloud computing, the application of … Read more
Introduction: The NB-IoT based smart fire early warning system consists of perception layer devices, NB-IoT network, a wireless connected fire warning monitoring platform, and terminal apps. It aims to address the lack of effective fire warning and prevention measures in residential homes and “nine small places” where fire safety is inadequate. (1) Overview of Achievements: … Read more
(1) Achievement Overview: The smart fire early warning system based on NB-IoT consists of perception layer devices, NB-IoT network, wireless connected fire warning monitoring platform, and terminal App. The perception layer devices include independent smoke fire detectors with wireless connectivity, independent temperature fire detectors, independent combustible gas detectors, and independent electrical fire monitoring detectors. This … Read more
A certain shopping mall has set up a fire automatic alarm system, where the 2# loop bus of the fire alarm controller is shared by two fire compartments on the first floor. Fire compartment one has 30 smoke fire detectors, 10 manual fire alarm buttons, and 10 bus modules (2 inputs and 2 outputs); fire … Read more
Bus control, as the name suggests, refers to a control system where many devices are set up on a single bus circuit. As shown in the figure below, all smoke exhaust outlets in the same smoke compartment can be controlled by a single bus control line. A button on the bus control panel can simultaneously … Read more
Bus control, as the name suggests, involves a single bus circuit connected to multiple devices. As shown in the figure below, all smoke exhaust outlets in the same smoke control zone can be controlled by a single bus control line. By pressing one button on the bus control panel, all smoke exhaust outlets can be … Read more
1. Principle of Short Circuit Isolators The short circuit isolator is a device used in the transmission bus of fire alarm systems that isolates the branch line during a short circuit. It automatically makes the two ends of the short circuit section high resistance or open circuit, preventing damage to the controller and not affecting … Read more
Bus short-circuit isolators are mainly used to isolate components on the bus, isolating fire detectors, combustible gas detectors, manual alarm buttons, sound and light alarms, etc., in certain areas or segments, to avoid affecting the reliable operation of the unisolated area system. This is crucial for maximizing the overall functionality of the system without being … Read more
