GST-DC-9503E Loop Isolator
Model No :
DC-9503E
Part Code :
DC-9503E

Overview

In fire alarm system, such condition often occurs that partial short circuit of loop affects the whole system. DC-9503E Loop Isolator can isolate the shorted circuit from the whole system to ensure normal operation of other devices and locate the devices in fault. After the short circuit fault is cleared, those devices will be re-introduced into the system. DC-9503E is suitable for Class A and Class B wiring.

Features
- Isolation of short circuit, automatic restore when short circuit is cleared.
- Support Class A or Class B wiring
- Rail mount or surface mount
•Standards: EN 54-17:2005
