Position 8 The remote data stream is forwarded together with local alarm information in an RS232 electrical format to external equipment e g a PC or other system controller in response to a poll command on the serial data input via the D Sub connector at the rear of the 19 rack shelf The remote module status 15 also made available in parallel form via the D Sub connector This allows the system to be integrated into redundantly switched network The Alarm Concentrator modules are bi directional so that the status of remote modules can be determined at either end of cross site connection This greatly aids the commissioning and fault location during installation Alarm Concentrator Alarm Concentrator Transceiver LAC 1 Transceiver LAC 5 2 5 4 20 Lo 23 23 ae 28 aE TE 2 2 2 GE ne aL Parallel output of remote status Parallel output of remote status A Cross site Fibre Optic Cable Serial RS232 Rx Lei Serial RS232 data output S Se data output Alarm inputs from Alarm inputs from local modules H local modules 2 1 Module Operation 2 1 1 Installation The Alarm Concentrator module is available in plug in module form for use in PPM s ViaLite 19 Rack Case or in standalone configuration with Converter Sleeve2. If the module is being used in conjunction with the 19 Rack Case the Alarm Concentrator must be inserted into position 8 immediately to the left of the power supplies This as shown in silkscreen on the backplane and engraved onto the rear panel The module is hot pluggable so can be inserted with power supplied to the rack case without affecting signal modules already installed Optical connections between local and remote modules are made at the rear of the module Using two clean FC APC cross site cables link the input ports I of each module to the output ports O of the mating module 2 2 Fibre Optic Cable amp Connectors 2 2 1 Care of fibre optic connectors Modern optical connectors offer very high levels of performance reliability and repeatability However they are more sensitive to damage and contamination than electrical connectors In order to maintain full performance from your fibre optic link system it is necessary to take care to protect the connectors from damage and to keep them clean The light carrying core of a singlemode optical fibre is 8 um in diameter and in a mating connector pair the two cores must be aligned to better than lum in order to minimise insertion loss The optical connectors used in PPM s systems maintain their performance even after hundreds of matings as long as they are kept clean Dirt or contamination may result in the core being obscured or misaligned and this in turn results in hi
