1

   Inputs 1 and 2: Hardwire bypass Fire Microphone inputs. 

2

   It is possible for some message slots to have standard ADPCM messages, while others contain .wav format messages 

3

   DVA concatenation capability: one DVA can occupy the memory space of up to four consecutive DVAs. 

4

   ADPCM and .wav message files should be converted to Motorola 'S' record format in order to be loaded to the VAR Router. Refer to ASL for details. 

5

  The RS232 port is internally used for system networking when the VAR8(EN54) is fitted with the VAR-ANIC Network Interface Card. It may be 

temporarily disconnected from the network, and connected to a Host PC for configuration purposes. 

6

   PC/DVA system can only be connected to stand-alone VAR8(EN54). 

7

   The analogue inputs and digital outputs replace the digital inputs available on standard VAR8(EN54).
