Nurse Call Installation Instructions
1 Introduction
This document describes the Nurse Call communication interface of the Precision Flow Plus
device. This document is intended for use by hospital IT, biomedical engineering or other experts
who wish to connect the Precision Flow Plus into a Nurse Call system.
2 Scope
This document applies to the current design and embedded firmware version of the Precision
Flow Plus unit. The current software version is 3.12.0. This document does not cover any
earlier versions of Precision Flow Plus embedded firmware and will require a review and
update for future versions of the firmware.
3 Hardware Interface Description
3.1 Nurse Call Interface
The Nurse Call / EMR Communication Cable (Part No. 3100897) contains a 3 pin 3.5 mm Stereo
Audio Jack (See P2 in Figure 1) for indicating an alarm condition on a hospital nurse call system
and a DB9 female Data Jack for interfacing Electronic Medical Record capable technologies.
An adapter or re-termination of the cable’s 1/8 in. (3.5 mm) stereo audio jack connection will be
necessary and shall be supplied by the user to connect the Nurse Call Interface Adapter to the
hospital’s nurse call system.
4 Wiring Guide: Connecting the Nurse Call Cable
The cable’s 3.5mm stereo jack supports “Normally Open” and/or “Normally Closed” Nurse Call
system connections.The signals on the 3 connector contacts are (see P2 in Figure 1 and Figure
1A):
• Normally Closed (pin 18 of HDMI connector) Ring or Right Channel of 3.5mm audio Jack
(See Figure 1A)
• Normally Open (pin 14 of HDI connector) Tip or Left channel of 3.5mm audio Jack (See
