MODEL FAMILY CB-LIM-01
Clarity IM
Continuous local visibility for a designated isolated power system.
Clarity IM is presented as the monitoring point for a North American isolated power system. It gives the project team a defined place to review system condition, set the expected alarm behavior and coordinate how staff receive an indication.
SYSTEM ROLE
What this family is designed to do.
A line isolation monitor observes the isolated circuit and signals a possible hazard condition according to its configured alarm threshold. It works with the isolated power system as a whole and presents the system status to staff.
INSTALLATION
See the system relationship →Locate the monitor where the intended clinical or facilities staff can see and respond to its indication. Coordinate room display, remote annunciation, test access and alarm wording before the panel schedule is finalized.
