Tyco 5B-I Isolator Base 5" for 600/800 Series 517.050.018

The Tyco 5BI Isolator Base 517.050.018 is a base for both the MX detectors, and a protection device against short circuits on the MX addressable loop. The Tyco 5B-I monitors the voltage on the loop and isolates the affected section when a short circuit is detected.
