Using a Nurse Call System
You can use an institutional Nurse Call system with your device.
There are several Philips Respironics cables available to connect a
nurse call system to the device. Refer to the instructions included
with your cable assembly if you have questions on how to connect it
to the device.
Using a Secure Digital (SD) Card
An SD card is provided with the device to record device usage
information. You can insert the SD card into the SD Data Card slot on
the left side of the device. Make sure the label on the SD card faces
the back of the ventilator.
To insert the SD card:
1. Open the SD card door by sliding the door forward and then
pulling it out, as shown below.

WARNING
Ensure that the Nurse Call
systems used do not exceed SELV
(Safety Extra Low Voltage) levels
as described in IEC 60601-1.
SELV levels do not exceed a
nominal value of 25VAC or
60VDC at rated supply voltage
on the transformer or converter,
between conductors in an earth-
free circuit which is isolated from
the supply mains by a safety
extra low voltage transformer
or by a device with equivalent
separation.
WARNING
The Trilogy’s Nurse Call feature
is for use only in a medically
supervised environment.
WARNING
Do not rely on the audible
indicator provided by the Nurse
Call system as the primary
indicator of the operating
state of the device or of patient
events.
WARNING
The Nurse Call feature should
be considered a back-up to the
Trilogy device’s primary alarm
system. Do not rely solely on the
Nurse Call feature.
