							CONNECTING EXTENSIONS
Station Connections (Figure 3-4)
The CPU has 4-pin DDK connectors for eight stations. The
stations can be a combination of keysets or single line tele-
phones, but the system can only accept a maximum of six
single line telephones (ports 10 and 11 can only use keysets).
Refer to Part 4: Installing Optional Equipment for
instructions on connecting a power failure telephone.
Figure 3-4  STATION CONNECTIONS
1.Following the conventional color code, insert the DDK
connectors into the PCB. For example, the eight stations
in the system would have these connections:
Ext./PortDDK Connector Pair
10WHT-BLU / BLU-WHT / WHT-ORN / ORN-WHT
11WHT-GRN / GRN-WHT / WHT-BRN / BRN WHT
12WHT-SLT / SLT-WHT / RED-BLU / BLU-RED
13RED-ORN / ORN-RED / RED-GRN / GRN-RED
14RED-BRN / BRN-RED / RED-SLT / SLT-RED
15BLK-BLU / BLU-BLK / BLK-ORN / ORN-BLK
16BLK-GRN / GRN-BLK / BLK-BRN / BRN-BLK
17BLK-SLT / SLT-BLK / YEL-BLU / BLU-YEL
Note that single line telephones only use one-pair wire
(T/R). When installing a single line set, the second pair is
not used (H/L).

2.Install a modular jack for each extension within six feet
of the telephoneÕs location. See Figure 3-5.
3.For each keyset, run two-pair 24 AWG station cable from
the cross-connect block to the modular jack.  For each
single line phone, run one-pair 24 AWG station cable
from the cross-connect block to the modular jack.
4.Terminate the station cable to the modular jack lugs:
WHT-BLU to GREEN lug
BLU-WHTto RED lug
WHT-ORN to BLACK lug *
ORN-WHTto YELLOWlug *
* Lug not used when installing a single line phone.
5.Back at the MDF, run two pairs of cross-connect wires
(or one pair of cross-connect wires for single line
phones) between the pins on the B block and cross-con-
nect block to complete the connection.
6.Install bridging clips as required.
7.After completing step 6, you should be able to place and
answer calls at the extension.

							CONNECTING TRUNKS
Trunk Connections (Figure 3-7)
The CPU has 2-pin DDK connectors for three loop start CO
trunks.
Refer to Part 4: Installing Optional Equipment for
instructions on connecting a power failure tele-
phone.
Figure 3-7  TRUNK CONNECTIONS
1.Following the conventional color code, insert the DDK
connectors into the PCB. For example, the CPU would
have these connections:
TrunkDDK Connector Pair
1WHT-BLU / BLU-WHT
2WHT-ORN / ORN-WHT
3WHT-GRN / GRN-WHT
2.For each trunk, run one pair of wires from the DDK con-
nection to a 625 modular jack, which then connects to
the telcoÕs RJ11C jacks using a standard line cord (Figure
3-8 on the following page).
3.After completing step 2, you should be able to place and
answer calls over the connected trunk.

							ALARM SENSORS
Using External Alarm Sensors
The Auxiliary (3DHEXU) PCB provides one alarm circuit
which detects a make (open) or break (closed) contact
from an alarm. Programming determines if the alarm input
requires an open or closed circuit.
An alarm detection causes the system to send a signal to sta-
tions programmed to receive the alarms. The alarm signal
can also be sent to external paging speakers.
Installing an External Alarm Circuit (Figure 4-1)
CAUTION
Be sure the requirements of the alarm system sensors do not
exceed the system specifications of a loop resistance of less
than 100 Ohms.
1.Locate an available 2-pin DDK connector in an auxiliary
(C)block.
2.For the DDKconnector chosen, cross-connect the associ-
ated wire pair from the C block to the cross-connect block.
3.Install bridging clips as required.
4.Connect the two leads from the external alarm to the
associated terminals on the cross-connect block.
5.Plug the DDKconnector into the ARM connector on the
Auxiliary PCB.
6.  Set whether the alarm circuit is normally open or closed in
Program 44.  In system programming, enter the following:
1  *  1  *  then either 1 or 0
The above entry sets the following:  1 (Alarm 1) * (enter
information) 1 (Activate Alarm) * (enter information) then
either 1 (Normally open circuit) or 0 (normally closed cir-
cuit).
