Nurse Call Feature - Nonin Avant 4100 Operator's Manual

Using the Avant™ 4000 Digital Pulse Oximetry System

Nurse Call Feature

The Avant 4000 features a Nurse Call circuit that can be connected to a hospital
nurse call system, allowing alarm conditions to be recognized at a central monitoring
location and on the Avant 4000.
DIP switch 7 allows users to select the duration output of a signal. In the DOWN
position, a one-second signal is output when an audible alarm starts. In the UP
position, the nurse call signal is active during the entire duration of an audible alarm.
Included in the Nurse Call Circuit is a switch—located on the base of the back panel
and covered by the back cover to prevent accidental toggling—that allows users to
select NO (Normally Open—the left position) or NC (Normally Closed—the right
position). (See "Installing the Batteries" for instructions on removing the back
cover.) The Nurse Call Circuit can be used both when the Avant 4000 is plugged in
and when it is running on battery power.

Call system to ensure that the desired function is operational.
