Description:

The universal remote alarm indicator and test combination MK2430 is designed for visual 

and audible indication of alarm messages from Bender systems such as EDS, RCMS and 

MEDICS. In MEDICS monitoring systems, the MK2430 meets the requirements of IEC 60364-7-

710 and DIN VDE 0100-710:2002-11 in respect of test functions for IT system monitoring 

and alarms from changeover modules.

The IT system monitoring equipment can be tested using the programmable test button.

Important display functions:

The LC text display makes this information easy to understand. The connection between 

the MKs and the changeover and monitoring modules is implemented with bus technology. 

During normal operation, the MK2430 indicates the readiness for operation of the system. 

The MK2430-11 features 12 digital inputs allowing messages from third party systems to 

be recorded and displayed on the MK2430, for example from medical gases or UPS systems 

(special safety power supply sources).

Function description

On its backlit LC display (4 x 20 characters), the MK2430 displays messages from all BMS 

bus devices assigned via alarm addresses. As well as being used as a standalone indicator 

the MK2430 also supports parallel operation. In the event of an alarm message, the yellow 

“WARNING” LED or the red “ALARM” LED lights up and the message appears on the LC 

display in plain text format. At the same time there is an audible signal (acknowledgeable). 

If a second message is received whilst the first is still pending, the audible signal will 

sound again and the messages will flash up alternately on the LC display. The address of 

the device triggering the alarm can also be called up. The audible signal sounds again 

once a configurable period of time has elapsed.

Internal device parameters (alarm addresses, test addresses,…) and the parameter setting 

of EDS and RCM systems can be accessed via the menu system.

As a master, the MK2430 can also be used in installations with a number of IT and EDS 

systems.

The test button can be used to check the operation of an ISOMETER® isoMED427P or IRDH. 

A message is only output on the MK2430 on which the test button was pressed. 

When wiring the bus connection, please note that a 4-wire cable (2 x BUS, 2 x US) with a 

suitable cross section is required when the supply voltage US is incorporated in the cable. 

Display/operating elements

The backlit display features four lines of 20 characters. It supplies medical and technical 

personnel with information that is always clear and unambiguous, in order to help them 

to make decisions. Every alarm message comprises three lines which appear spontaneously 

and three additional lines which can be displayed at the touch of a button. The fourth 

line contains status information (number of messages, test procedures, menu information). 

Three LEDs are located above the text display. They indicate: normal operation (green), 

warnings (yellow) or alarms (red). Five buttons are available for acknowledging alarms 

and warnings, and for the menu system.
