Installation Instructions
DS7430 Multiplex Expansion Module
1.0 General Information
The DS7430 is a Multiplex Expansion Module for use with the
DS7400(Xi) Series Control/Communicator. It connects directly to
the DS7400(Xi) and provides a 2-wire multiplex bus for the con-
nection of Multiplex Sensors and Interface Modules.
• Current Draw: 65 mAh Standby or Alarm.
• Outputs:
DC Bus= 200 mA
Mux Bus= 75 mA
2.0 Installation
Failure to follow the mounting instructions in this
manual may result in damage to the DS7400(Xi)
Control Panel.
WARNING
The DS7430 and DS7400(Xi) contain static sensi-
tive components and must be handled with care.
Follow anti-static procedures when handling the
modules.
NO STATIC
• Install the DS7430 board prior to installing the DS7400(Xi) board
into the control enclosure. If the DS7400(Xi) board is already
installed in the control enclosure, remove the 7400(Xi) board at
this time.
• Place the DS7400(Xi) board on a flat surface with the compo-
nent side of the board facing up.
• Install the four plastic standoffs in the holes provided in the
DS7400(Xi) board. Avoid bending or flexing the DS7400(Xi) board
when inserting the standoffs. Be sure the standoff tabs are
aligned so that they do not touch any components on the mod-
ule. Be sure that the stand-offs are firmly pressed into the board
so that the "ears" can expand out. See drawings.
• Install the DS7430 board onto the standoffs, noting that the con-
nector pins from the DS7400(Xi) are properly aligned to install
into the connector on the DS7430. Avoid bending or flexing the
boards while pressing them onto the standoffs.
• The DS7400(Xi) control board may be installed into the control
panel enclosure at this time.
3.0 Wiring
Connect the multiplex loop to the DS7430 as shown. Up to 2000
feet (610 m) of #22 AWG (0.8 mm) or 5000 feet (1525 m) of #18
AWG (1.0 mm) wire may be used. Do not use shielded cable. Do
not share cable with the keypad lines.
The Bus Power output is for connection of separately powered
multiplex devices, such as the DS7432 8 Input Remote Module. If
using separate powered detectors, they should be powered from
the auxiliary power terminals of the DS7400(Xi).
4.0 Programming Multiplex Devices
To program multiplex devices, it is necessary to place the Program
Plug over the Enable Programming pins. The Program Plug must
be over the Disable Programming pins for normal operation.
for the
Stand-off "Ears"
Be sure that the Stand-off is pressed firmly
through the Printed Circuit Board, so that
the Stand-off ears can expand outward.
