Using a Nurse Call System
You can use an institutional Nurse Call system with your device.
Use only 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.
Philips Respironics strongly recommends using a Normally Closed
Nurse Call system. If a system with Normally Open logic is used, there
are certain situations where the Nurse Call system can not indicate an
alarm condition.
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 or
Remote Alarm feature is for use
only in a medically supervised
environment.
WARNING
Do not rely on the audible or
visual indicator provided by
the Nurse Call or Remote Alarm
system as the primary indicator
of the operating state of the
device or of patient events.
WARNING
The Nurse Call or Remote Alarm
feature should be considered a
back-up to the Trilogy device's
primary alarm system. Do not
rely solely on the Nurse Call or
Remote Alarm feature.
