Installing External Alarm Signals to Stations
This section provides information on the installation
of an external alarm.Two alarms can be connected to
the system.Programming determines if the alarm inputs
require an open or a closed circuit.
SpecificationsLoop Resistance: 1000 ohms max.
The BUSINESSCOM PLUS 
 requires a B-HBU-A PCB
of Series 3 or later.

Installing Power Failure External Bells
These customer-supplied bells provide ringing for in-
coming calls during an AC power failure only. Power
failure single line 
 sets can be used in
place of power failure bells. Only FCC-certified in-
stallers are permitted to install Power Failure Bells.
Installation,
BUSINESSCOM PLUS 8
Refer to Figure 2-23Installation of Power Failure
External Bells,BUSINESSCOM PLUS 
1. Connect external bell wires to the  Block at:
o Clips 
 for PF line 1
o Clips 
 for PF line 2
o Clips 
 for PF line 3
2.The  PCB in the KSU has six PFC straps.
Two of these straps aredesignated for each of
three PFC lines,for a total of three pairs of
straps.These straps are designated as 
PFC2,and PFC3.
Bridge  PFC2,and PFC3 to position  for
power failure operation on PF lines 1, 2, and 3,
respectively,
or
Bridge  PFC2,and PFC3 to position  for
no power failure operation on the respective lines.
Installation,
BUSINESSCOM PLUS 12
Refer to Figure 2-22:
1. Follow steps 1 and 2 above.
2. Connect external bell wires to the B2 Block at:
o Clips 
 for PF line 4
o Clips 
 for PF line 5
3. Bridge PFC4 and PFC5 on the 
 PCB in the
KSU to position 
 for power failure operation
on PF lines 4 and 5, respectively,
or
bridge to position  for no power failure
operation on the respective lines.

During a power failure, BUSINESSCOM PLUS key
telephones can provide answer-only operation.
Power Failure External Bells or ringers are
required to provide an indication of an incoming
call.Since a key telephone used for answer-only
power failure service is connected to one specific
line during power failure, none of its keys or
indications functions.
A standard 
 single line set, which
is temporarily installed,
can provide incoming and
outgoing power failure operation at a power failure
port.Power failure bells can be replaced with
standard 
 single line sets for permanent
power failure-only operation,
but a call is lost if
it is in progress when the power returns.

Installing the DSS Console
 A BUSINESSCOM PLUS  system can accommodate
more than one DSS Console of Series 2 or higher per
hook-up position on the 
 Block (see Figure 2-27
DSS Consoles).The DSS Console wiring is non-standard.
Due to strapping options on the Consoles internal
PCB,the Console can be used as an externally-powered
BLF unit, an internally-powered unit or as a DSS
Console.This section provides information on in-
stalling one, two, or three DSS Consoles in a
BUSINESSCOM PLUS 
Specifications1,000 (304.8  maximum of 24 AWG
Strapping
Options
DSS Console
Powered BLF
500 (152.4  maximum of 24 AWG if more than one
console is used.
A Console hook-up position on the 
 Block (i.e.,
clips 
 and clips  can accommodate one, two or
three Consoles in the following combinations:
o One DSS Console
o One BLF unit which can operate using internal 
power
o One DSS Console and one BLF unit
(The BLF unit can operate using internal power.)
o One DSS Console and two BLF units
(The first BLF unit can use internal power. The
second BLF unit must be externally-powered. The
customer provides the external power source which
must supply 18 VDC 
 200  The Nitsuko 
adaptor [P/N 30869 or P/N 851691 can be modified
for use as the local external power source.)
Straps 
TB2 and TB3 on the Consoles internal PCB
 must be set according to the Consoles use:
1. The Console is already factory-strapped for DSS
Console  operation. S e t  a l l  s t r a p s  t o  l - 2 .
2. Install as described below.
3. Be sure to make entries in Programs 13 and 39.
1. The strap setting depends on whether the BLF unit
is accompanied by a DSS Console on the hook-up
position:
o If the BLF unit is accompanied by 
a DSS Console,
set 
 to 2-3,
and set TB2 and TB3 to l-2.
o If the BLF unit is the only device on the hook-
up position,set all straps to l-2.
2. Cable unit as described below. Do 
not make entries
in Programs 13 and 39 for BLF-only.
