Fire-Lite B224BIA-WH SD365 Series Isolator Detector Base, White

B224BI Plug-in Isolator Detector Bases prevent an entire communications loop from being disabled when a short circuit occurs. They accomplish this by isolating that part of the loop containing the short from the remainder of the circuit. These bases also automatically restore the entire loop when the cause of the short circuit is corrected. In general, up to 25 addressable devices may be isolated between isolator bases.
