These terminals are used for multiplex communications in a system utilizing the
Fiber Optic interface Style 3 or Style 7 wiring.
2.11.2.2 Terminals 3 and 4 (Channel B)
These terminals are connected to the secondary channel of a system utilizing the
Fiber Optic interface Style 3 or Style 7 wiring.

2.12 EXP-8Z
2.12.1 GENERAL
Each EXP-8Z EOL interface board may be jumper selected for any available zone
group for both the DGM-32 and DGM-64. This board is optional and is only used
when the DGM is connected within 20 feet of the initiating device. Use of these
boards and configuration of the DGM is a special order. These boards are available
primarily to customers who wish to expand existing DGM panels that already contain
EXP-8Z EOL cards. The current DGM design uses one or two 32 Zone EOL cards in
lieu of the EXP-8Z cards.
The EXP-8Z board does not provide lightning protection for each zone input. Please
refer to
Section 2.13.1, 32 Zone EOL.
2.12.2 INSTALLATION
STEP 1: Place an EXP-8Z board over the mounting holes and start the top left and
top right mounting screws.
STEP 2: Start the lower left and lower right screws and tighten all mounting screws.
STEP 3: Connect the ribbon cable plug from P0 of the main board or from P1 of the
previous EXP-8Z to P1 of the EXP-8Z being installed.
2.12.3 WIRING
2.12.3.1 BS1 and BS2
Barrier strips BS1 and BS2 contain terminals for the connection of field wiring to the
Class B zone initiating inputs. Zone numbering is shown for the EXP-8Z supplied
with the system. For additional boards, terminal designations increase by eight for
each expansion board.
