Product description:
LDF6 series combined residual current fire monitoring detector integrates the leakage current transformer and temperature control with the circuit part to reduce wiring errors during construction. The product is convenient for wiring and stable in function. It adopts microprocessor chip. If the set value is exceeded, an audible and visual alarm will be issued, and the alarm fault will be transmitted to the upper computer at the same time.
Scope of application:
It is suitable for installation and use in factories and mines, institutions, schools, shopping malls, hotels, entertainment places, residential buildings and family homes. The application is used to monitor leakage current, cables, cable terminations, and thermal faults produced by intermediate joints. Temperature monitoring of cable junctions and intermediate junctions.
