Installation
IMI 66-031
An optional station is available which is equipped with a 14 station
Busy Lamp Field (BLF).
up
to eight BLF stations can be connected to
the system.
A BLF station can be connected to any odd or even station
port in the system per the following guidelines.
l
The installed distance between the KSU and the BLF station must be
limited to 1000 feet or less.
OThe data-line paired station port cannot be used as a BLF station
connection or as a regular station connection.
Data-line pairing
is: 10-11,
12-13, 14-15, 16-17,
18-19, 19-21,
22-24, and 23-25.
l
The overload paired station port cannot be used as a BLF station
connection but can be used as a regular station connection.
Overload pairing is:
10-12, 11-13, 14-16, 15-17, 18-20, 19-21,
22-24, and 23-25.
l
A port, paired in either manner with a BLF station, can be used as a
PA port if desired.
The optional DSS/BLF console may be installed at any station port to
r
work in conjunction with a companion system station connected to the
adjacent port (e.g.;
port 10 for station and port 11 for console).
The installed distance limit between the KSU and the console is the
same as that specified for the companion station.
Connect all four
wires (voice pair and data pair) of the console cable to the station
connection block.
The voice pair connections of the console can be used simultaneously
to enable a PA port function.
Refer to the paragraph in this chapter
headed Q&Q &SW m& J&&MS w&* and to the illustration shown
in Figure 5. Per that discussion,
wire a PA amplifier input to the
DSS/BLF console voice-pair at the station connector block clip
terminals.
Use an audio matching transformer, as discussed in the
referenced paragraph and illustration, to provide isolation.
If an
enable signal is required with the particular PA equipment being used,
the console and PA equipment connections are limited to the station
ports specified in the above mentioned reference.
The DSS/BLF console port must be programmed as a DSS/BLF port (see
Chapter 4 for programming details) before console operation can take
place.
The console port must be also programmed as a PA port if a PA
amplifier has been.connected to the voice pair as part of the system.
