Automatic fire alarm system-Yingkou New Shanying Alarm Equipment Co., Ltd.

Product Features

Directionless and non-polar;

The protection devices connected between the signal bus and the coding devices are suitable for engineering ring wiring and branch wiring.

When there is an open circuit in the signal bus, power will be supplied to the open circuit location through the ring wiring to ensure the normal operation of the line.

When a local short circuit occurs, the fault area is automatically isolated to ensure the normal operation of other coding devices.
