2 EQUIPMENT OVERVIEW

2.1 Product Description

Remote Alarm Box (RAB)

The Remote Alarm Box is a microprocessor controlled isolation
relay (secondary alarm device).
It is used to connect the device listed below to the hospital alarm
system:

• Dash patient monitors

• Dash Port Docking Station

Figure 2.1 Remote Alarm Box

• Solar 8000M patient monitor

Remote Alarm Box with Remote Light (RAB RL)

The RAB RL is used to connect an alarm light (Remote Light, P/N
8500 AAX) to the devices listed above (secondary alarm light). This
RAB RL does not connect to the hospital alarm system. A special,
hospital grade power supply unit is required to supply power to the
alarm light;
This unit is included in the shipment.

2.3 Description of Operation

Figure 2.4 RAB Block Diagram

Block diagram of RAB :

The interface to the connected Patient Monitoring System is realized by a standard serial RS232
communication interface. So, in different to the existing Isolation Boxes („Nurse Call Boxes“) a small
microprocessor is needed to realize the communication part of the box. The RAB / RAB RL operation
mode could be configured by three configuration jumpers.
The µProcessor is requesting every 500ms the alarm status of the patient monitor via serial communication
protocol. If the Monitor is in “ALARM”-state, the RAB / RAB RL toggles the alarm relay according to the
configured alarm mode. If the Monitor is not in this state, the RAB / RAB RL switches the relay back (if it
was in alarm state) or the relay remain the “non-alarm” position according to the configured operating mode.
After power up of the RAB / RAB RL there is a onetime switch delay of approx. 20 seconds to let the patient
monitor startup to normal operation.
An independent hardware watchdog / power supervisor chip is provided to guarantee proper powerup/
powerdown and software behavior.
The configured device status and also the detected alarm status are displayed by 5 LED’s.
On Patient Monitor side the communication interface is realized as a M-Port interface with an 8-pin RJ-45
connector.
To connect the box to a hopsital alarm call system a 3 terminal screwing connector is provided and to
connect the RL version of the RAB to the EAGLE Remote Light and external IEC601-1 power supply, a 9­pin SUB-D and a 3-pin power connector are used .

3 MAINTENANCE

3.1 Maintenance Schedule

Manufacturer
Recommendation

To make sure the RAB / RAB RL remains in proper operational and functional
order, a good maintenance schedule must be adhered to.
The manufacturer's recommendations in this regard are as follows:

• Visual Inspection: These should be performed by qualified service personnel upon receipt of the
equipment, every 12 months thereafter, and each time the monitor is serviced.

• General Cleaning: Service personnel should perform this after servicing the monitor.

• Checkout Procedures: These should be performed by qualified service personnel upon receipt of the

equipment, every 12 months thereafter, and each time the monitor is serviced.

• Leakage Current Tests: These should be performed by qualified service personnel upon receipt of the
equipment, every 12 months thereafter, and each time the monitor is serviced.

• Maintenance “Blink Mode” : If Blink mode is used a special maintenance must be performed by
qualified service personnel every 12 months.
