Spectra Alerts: Nurse Call Interface
Nurse Call Interface
The Spectra Alerts option includes a Nurse Call Interface rear panel connector, as
shown in the Figure below. This connector attaches to a standard Nurse Call System.
The connector’s maximum output is 50 Vdc at 100 mA; the maximum on resistance
is 0.5 Ω. When connected to a Nurse Call System, the monitor will activate the
system each time a Spectra Alert is issued. This interface simulates pressing the
button on a bedside Nurse Call System allowing nurses to respond to patient needs
quickly and efficiently. Refer to the 250cx Series Service Manual for more
information.
NOTEIf the Spectra Alerts are suspended (see “Alert Suspension Feature” on
page C-7), the Nurse Call output is inhibited during the suspension time.
