GST C-9504E User manual

30309828 Issue 1.02
Features
Automatically isolating short circuit part on the
loop and automatically restoring it when short
circuit is corrected.
Used as detector base.
Standard: EN54-17.
Description
In loop type fire alarm system, it often occurs that
partial short circuit of loop affects the whole system.
C-9504E Base Mount Short Circuit Isolator can isolate
the shorted circuit from the whole system to ensure
normal operation of the remaining parts and locate the
failed part by illuminating a yellow indicator. When the
short circuit fault is cleared, the shorted part will be
restored.
The isolator is applicable to all loop type fire alarm
systems, either Class A or Class B loop.
