Extends from 5 – 15 ft

Used with FireWarden Series panels to protect the system against wire-to-wire short circuits on the SLC loop

System Sensor B224BI-IV S/F 24/09 Rechargeable sealed lead-acid batteries areThe B224BI WH and B224BI IV isolator bases are intended for use in an intelligent system. Isolator 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
