The ARCM residual current electrical fire monitoring detector is installed in 0.4 kV low-voltage distribution systems to detect residual current, temperature and other electrical parameters related to electrical fire hazards in TN-C-S, TN-S and local TT systems. When the monitored parameters in the protected circuit exceed the alarm setpoints, alarm and control signals are issued so that electrical fire hazards caused by residual current can be eliminated. The product uses RS485 bus communication and can be combined with other alarm units, monitoring units or monitoring hosts to form a fire monitoring system. A centralized bus-type information management mode or a zone-based information management mode can be selected according to user requirements.
Application scope: suitable for intelligent buildings, high-rise apartments, hotels, restaurants, commercial buildings, industrial and mining enterprises, key national fire protection units, and the petrochemical, education and healthcare, financial and telecommunications sectors.
