Toa EXES-6000, Operating And Troubleshooting

Assigning each station to the designated paging
zone will require the assignment plug for the
EX-610 and EX-620, and the SA unit (SA-64) for
the EX-630. Supose that 4 LM units, LM(1) to
LM(4) (32 stations, No.200 through No.231) are
used in a system, with stations No. 200 to No.
203 assigned to zone P1, stations No. 204 to No.
220 to zone P2 and stations No. 223 to No. 227 to
zone P3. See Fig. 34. The station number for each
paging group should be consecutive numbers.
(1) To separate each zone, cut jumper wire JP6
of LM(1), JP7 and JP9 of LM(3) and JP6 of
LM(4). When the paging group has a station
which does not require to be paged, remove
the resistor in the LM unit for that station. In
this example, the resistor in LM(3) for station
No. 217 is cut.
(2) Make connections for paging zone assign-
ment in the SA unit.
(2)-1 The exchange is so designed that the paging
outputs of the PI unit are connected to the
inputs PAGING No. 1 to No. 31 of the SA
unit, and the paging inputs of the LM unit to
the outputs LM No. 1 to No. 32 of the SA
unit. Therefore, each input of the SA unit
needs to be connected to the first or last
station number of the LM unit. In this
example, the input PAGING No. 1 is con-
nected to station No. 200, PAGING No. 2 to
station No. 207 and PAGING No. 3 to station
No. 223.
(2)-2 When a certain paging zone extends to more
than one (1) LM unit, connect between the
last and first inputs of the LM units involved.
In this example, STATION No. 207, No. 208,
No. 215 and No. 216 are connected for zone
P2 because it extends to 3 LM units. Another
connection is made between STATION No.
223 and No. 224 for zone P3 because it
extends to 2 LM units.
(2)-3 Because each paging input of the LM units is
grounded through jumper wire in the SA unit
to prevent cross-talk, cut the jumper wires (in
the SA unit) corresponding to the LM units
used for paging. In this example, the follow-
ing jumper wires in the SA unit are cut:
No. 200 and No. 207 for LM No. 1
No. 208 and No. 215 for LM No. 2
No. 216 and No. 223 for LM No. 3
No. 224 for LM No. 4
As far as LM unit (4) is concerned, when the
paging group is assigned as shown in Fig.34,
its corresponding jumper wire No. 231 in the
SA unit should not be cut.
(3) When using 2 or more PI units, cut the all-call
paging jumper wire in the second and its
subsequent PI units.
