Fire alarm system

Loop Card.

One output is activated when the general fire alarm
indication is activated. This output can be connected
to the general fire alarm input on the base card. One
output is activated when the fault indication is activated.
The loop cable can be fed from both sides, the A and
B side, forming a ring where a maximum of 254 loop
units can be connected.
Individual control of DC output (A or B side). The
loop is electrically isolated from the system if both
DC outputs to the loop are deactivated.
**Low voltage and high current are supervised.

Не совсем ясно послед. предложение.

контроль низкого напряжения и высокого тока :)))))

Контролируются состояния низкого напряжение и сильного тока (в шлейфе) - это означает неисправность шлейфа/извещателей
