Silent Knight SK-ISO Line Isolator Module

The SK-ISO functions as an automatic electronic switch that opens when the signaling line circuit voltage drops below 4 volts. This isolation capability helps prevent a short circuit in one section of an SLC from disrupting other properly connected and isolated devices.

Designed for compatible intelligent addressable fire alarm systems, the module continuously monitors the applicable SLC conditions and responds automatically when a qualifying short-circuit fault occurs.

A panel-controlled status LED provides visual operating information. The LED flashes green during normal operation and displays solid red during an alarm condition, as specified in the supplied product information.

The SK-ISO supports compatible 5700, 5808, 5820XL, and 5820XL-EVS addressable fire alarm control panels running software version 10 or higher.

Ideal for commercial buildings, institutional facilities, and other addressable fire alarm installations, the SK-ISO helps improve signaling circuit fault isolation and system reliability when installed according to the approved circuit design.
