500 Series Fault Isolator Module

Fault Isolator Modules are generally used at each T-tap branch, to limit the effect of short circuits on a branch to the devices on that branch. The LED indicators in modules are continuously ON during a short circuit condition.

Overview

Fault Isolator Modules automatically restores the shorted portion of the communications loop to normal condition when the short circuit condition is removed. They automatically open circuit when line voltage drops below four volts. Fault Isolator Modules should be spaced between groups of addressable devices in a loop to protect the rest of the loop. If a short occurs between any two isolators, then both isolators immediately switch to an open circuit state and isolate the groups of sensors between them. The remaining units on the loop continue to fully operate.

Features & Benefits:
  • Powered by SLC loop directly, no external power required
  • Integral LED blinks to indicate normal condition. Illuminates steady when short circuit condition is detected
  • High noise (EMF/RFI) immunity
  • Wide viewing angle of LED
  • SEMS screws with clamping plates for ease of wiring
  • Opens SLC loop automatically on detection of short, preventing the short from causing failure of the entire loop
  • Automatically resets on correction of short
  • Supports Style 4, 6, or 7 wiring
Certifications:
  • UL: S1570
  • ULC: CS669
  • FM Approved
  • CSFM: 7300-0554:152
