Intended use The CARESCAPE RAD is intended for relaying primary alarm signal from the host device to a remote alarm system. The CARESCAPE RAD is intended for use in multiple areas within a professional healthcare facility. The CARESCAPE RAD is intended for use on distributed alarm system. The CARESCAPE RAD is intended for use under the direct supervision of a licensed healthcare practitioner, or by personnel trained in proper use of the equipment in a professional healthcare facility. The CARESCAPE RAD is not intended for confirmed delivery of alarm. The CARESCAPE RAD is not intended for use within controlled MR environment. WARNING
MISSED ALARMS. Wrong alarm settings at the host monitor may lead to compromised patient safety through missed alarms. To avoid this risk, always check that the alarm settings at the host monitor are appropriate for patient use.
WARNING
MISSED ALARMS. Do not rely entirely on a distributed alarm system when using CARESCAPE RAD. As a one-way system, CARESCAPE RAD does not control whether all alarm signals reach their final destination and are signaled there. This may lead to missed alarms. Always check alarms on the monitor.
Distributed alarm system You can use the CARESCAPE RAD for relaying a primary alarm signal from a CARESCAPE monitor to a hospital remote alarm system, for example, like a nurse call system or a remote alarm light.

Theory of operation
4
Overview of the operation The CARESCAPE RAD is a USB low-power device with two mechanical relays. The state can be set through the state of the relays through the USB interface. These two change-over (SPDT) switches can be used for relaying a primary alarm signal from a CARESCAPE monitor to a hospital remote alarm system. The USB interface is used to: ●
Read back the relay coil state: energized / not energized.
●
Change the state of the connection and activity status indicators.
The CARESCAPE monitor software controls the operation of the CARESCAPE RAD, the activation of the relays and the indicators. To configure all the settings described in this chapter, use the CARESCAPE monitor clinical and service interface.
Block diagram
Initialization When a host monitor powers up the CARESCAPE RAD, it initializes the communication between the device and the monitor. The remote alarm device receives power from the monitor’s USB connection. When the internal power up process is complete, the amber connection status indicator is momentarily turned on. Then the monitor loads

Theory of operation
the device driver, initializes the communication with the remote alarm device, and sets the initial state of the two changeover switches. The initial state of the relay coils depends on whether Remote alarm device power failure detection is disabled or enabled. Refer to the following table: Remote alarm device power failure detection setting
Control signal for activity status indicator
Control signal for relay coils
Relay coil state
Disabled
Low /0 (not lit)
Low /0
De-energized
Enabled
Low /0 (not lit)
High /1
Energized
When the initialization is complete, the monitor changes the color of the connection status indicator from amber to green. The remote alarm device is now ready for use. NOTE
Initialization completes only if Remote alarm device operation is Enabled.
Power failure detection mode When the power failure detection mode is activated, the CARESCAPE RAD triggers an alarm in the remote alarm system if the device loses power. This happens, for example, if the USB cable is accidentally disconnected, or if the CARESCAPE monitor is shut down or loses power. The CARESCAPE RAD uses separate control lines for the activity status indicator and the relay control. This allows the monitor software to energize the relay coils during initialization without turning on the activity status indicator at the same time. If the CARESCAPE RAD loses power, the relay coils become de-energized and trigger an alarm in the remote alarm system. The duration of the power loss does not have any effect on the device operation. To activate this feature, select Remote alarm device power failure detection > Enabled. NOTE
To avoid false alarms, GE recommends that you only enable the remote alarm device power failure detection setting when the CARESCAPE monitor is in stationary use and there is no need to disconnect/reconnect the USB cable or shut down the monitor.
Alarm activation The host monitor sends an alarm to the remote alarm device only if the priority of the alarm is equal to or higher than the priority selected as Remote Alarm Device Priority. When the monitor has triggered an alarm condition in the device, the signal status and relay coil state depend on the Remote alarm device power failure detection setting. Refer to the following table:
