Equipment overview: Theory of operation
2-40 Dash 3000/4000/5000 2000966-542D
ALARMS — Explains low battery and battery fault alarms and
messages.
FAULT STATUS MESSAGES: — General, charging, and
temperature failures indicate that the battery has failed, or the
charging of the battery has failed. Replace it with a different
battery.
CONDITION: — Condition this battery using an external
battery charger.
LOW BATTERY ALARMS: — The patient monitor will issue a
System Warning alarm when there is approximately 10 minutes
per battery run time remaining. The patient monitor will issue a
System Warning alarm when shutdown is imminent (less than
one minute left of remaining run time).
Speaker
The speaker is used for audible notification of alarms.
Handle subassembly
The handle serves multiple purposes in the patient monitor. The
modular design enables the user to add adapters for specialized
applications.
The Dash 3000 handle houses the optional alarm light. This light is
visible for 360° surrounding the patient monitor. The light is intended for
applications when the audible notification is not useful or effective, such
as noisy environments (e.g., emergency vehicles) or quiet environments
(e.g., neonatal care areas). The alarm light indicates two levels of visual
alarms:
Crisis alarms (red LED) and
Warning alarms (amber LED).
The handle also houses the wireless card antennas required for the
optional wireless card subsystem.
Interfaces
Ethernet
The Ethernet RJ-45 port provides a hardware connection to the optional
CARESCAPE Network. The patient monitor has a built-in transceiver
for twisted-pair wire. Basic insulation (1500 VAC) isolates the patient
monitor from networked devices.
AUX
The AUX RJ-45 port provides an asynchronous communication
connection to devices within the bedside care area. Basic insulation (1500
VAC) isolates the patient monitor from other devices.
