............................ European Fire Interface Card - factory fit option ordered with VAR8(EN54) or VAR8-E(EN54)
9 analogue inputs (non-isolated analogue interfaces with internal pull-up to +5 V by 4.7 k
Ω
)

Third-party Fire Loop Interface........................................................................... 1 (can only be fitted to VAR8-E(EN54))
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).
