BPS monitoring functions

Function sheet

The VISONIK BPS monitoring functions control the execution of processes in the

building services systems assigned to them and trigger reactions as well as

acoustic and optical alarms in the event of irregularities.

The illustration below is a schematic diagram of a simple example: The VISONIK

BPS—either connected locally or via telephone line—detects faults in the plant via the

I/O module and generates appropriate messages on the printer.

listedinanoverview.

Local messages Fault messages and alarm reports are output locally.

Remote alarming A printer with modem connection (teleprinter) is set up at the

workplace of the person responsible for the plant. In the event of a

fault, a telephone connection is established and the fault message

or alarm report is transmitted.

The benefits of monitoring with messages, reports, and alarms are dependable

operation and cost reductions because:

– Measures are undertaken before a serious fault or plant damage occurs.

– The causes of any existing fault are quickly recognized.
