Isolator Detector Base

System Sensor B524IEFT-1 isolator base prevents an entire SLC from being disabled when a short circuit occurs. It achieves this by isolating the part of the loop containing the short circuit from the remainder of the circuit. The base will automatically restore the entire loop when the short circuit is corrected. Up to 40 devices may be isolated per isolator base depending on the device type.

  • Universal for all plug-in addressable detectors
  • Tamper proof lock
  • Multiple hole centres
  • Low profile (26mm)
  • Low Current consumption (100 µA)
  • Up to 99 isolators per loop
  • Complete isolation of short circuits
  • Automatic restore when short circuit is corrected
  • Remote LED Connection
