♦ Product Description:

A residual current fire monitoring detector from the LDF5 series is a self-contained intelligent detector. The electric fire monitoring detector, as the relay part of the signal processing of the electrical fire monitoring system, can intelligently analyze and process the signal transmitted by the lower-level terminal probe through the built-in circuit and software, in order to judge the status of each probe of the lower-level terminal (that is, the fault state, fire alarm status, normal working status), and send the fault, alarm, and other information of each probe of the lower-level terminal to the electrical fire monitoring system. Monitoring and alarming processing in its entirety.

♦ Basic Functions

Probe fault diagnosis, high alarm accuracy, strong reliability (can effectively prevent false alarms and omissions), miniaturization, multi-function, simple and practical, and easy installation are all features of the detector. It can be used for electrical safety and fire protection in hotels, business and summer gymnasiums, hospitals, libraries, computer rooms, bazaars, public cultural and entertainment venues, schools, cultural relics protection units, factory workshops, general warehouses, and other locations. It is not, however, suited for use in combustible, explosive, or severely corrosive conditions.
