COMBINED REMOTE ALARM DEVICE Russian patent published in 2018 - IPC H02J13/00 H01H9/16 H01H83/00 

FIELD: electrical equipment.

SUBSTANCE: combined remote alarm device (1) for the several configured to be in-series in a row arranged overvoltage protection devices (ÜSG₁, ÜSG₂). Each overvoltage protection device (ÜSG₁, ÜSG₂) has the associated remote alarm module (FM₁, FM₂) docking devices, which in its turn has corresponding devices for attachment to the overvoltage protection device (ÜSG₁, ÜSG₂), at that, the remote alarm modules (FM₁, FM₂) are also arranged with possibility of sequential arrangement in a row. Wherein, the remote alarm modules (FM₁, FM₂) on the sides, which may be adjacent to the next remote alarm module (FM₁, FM₂), have contact parts (KM_1,1, KM_1,2; KM_2,1, KM_2,2), which allows the remote alarm adjacent modules (FM₁, FM₂) serial connection in a row. In the event of the overvoltage protection (ÜSG₂) device malfunction the remote alarm module (FM₂) interrupts electrical serial connection to the remote alarm adjacent module (FM₁) or to the several neighboring remote alarm modules.

EFFECT: enabling the overvoltage protection device and the remote alarm module reliable connection with possibility of delayed retrofitting and the mechanical indicator mechanical probing.
