VI-6157

VI-6157 Loop Card: It is mainly
used to connect alarm devices such as smoke detectors and heat detectors, as well as control modules, sound and light alarm devices, etc. The loop adopts a non-polar wiring method, which makes on-site wiring convenient. The output end of the loop bus is equipped with multi-level protection devices to prevent the interference of the customer's bus loop signal and the impact on the equipment caused by short circuits. It adopts a flexible plug-in installation method with the controller, making it convenient to add loops in the later stage. It supports the free switching between two wiring methods, namely Class A and Class B. a single card can carry 256 points in the Class A wiring mode, and 512 points in the Class B wiring mode
