for the
DS7432 Eight Input Remote Module
1.0 Description
The DS7432 is an Eight Input Remote Module that provides a
means of addressing up to eight input loops of conventional
contacts to the multiplex bus of the control.
2.0 Specifications
• Control Panel Requirements: The DS7432 is designed
to work with the following control panels:
• A DS7400, DS7400X, DS7400Xi, DS7400Xi Rev. 3 or
DS7400Xi Rev. 4.
•
Up to 7 DS7432s can be used per DS7400 system.
•
Up to 15 DS7432 modules are allowed on DS7400X,
Xi and Xi Rev. 3.
•
The DS7400Xi Rev. 4 control panel can support up to
30 DS7432 modules.
• One DS7430, DS7436 or DS9431 Multiplex Expansion
Module is required in the system to use the DS7432
Remote Module.
• Current Draw: 10 mA Standby, 10 mA Alarm
• Minimum Bus Voltage For Operation: 8 VDC peak
• Wiring: Refer to the reference guide for the panel's
multiplex expansion
requirements. The length of the wire connected to the loop
inputs on the DS7432 must be less than 250 ft. (76 m) per
loop.
• The recommended wiring to the control is standard #18
(1.22 mm) or #22 (0.74 mm) AWG, quad (4-wire) cable.
Do not use shielded or twisted pair cable.
• For fire applications, #18 AWG (1.2 mm) wire is
required.
3.0 Installation
P3 of the DS7432 is for European application
only. Do not put a jumper here.
P2 of the DS7432 allows the tamper switch to be bypassed
with a jumper when testing or servicing.
Remove jumper P2 when testing or servicing
has been completed.
Use the mounting holes (upper left and lower right corners) to
mount. It can be mounted inside or outside of the control
enclosure.
Route wiring as necessary from the DS7430, DS7436 or
DS9431 in the control enclosure and from the remote devices
to the DS7432.
Connect wiring as shown in Figure 3.

If using separate powered detectors (other than
smoke detectors)
Control/Communicator, the DS7432 can be
powered from the control panel auxiliary power
(terminals 7 and 8). The detector can be
connected to the DS7432 (see Figure 4). This
eliminates the need for home-run power wiring
from each detector to the control when the
DS7432 is mounted outside of the enclosure.
Be sure all wiring is unpowered before routing.
If the wiring is to enter through the rear of the enclosure, open
the DS7432's rear wire entrance. If the wiring is to run along
the surface of the enclosure, open the DS7432's surface wire
entrance. See Figure 2.
4.0 Programming
4.1 System Programming
Refer to the System Programming section in your panel's
reference guide for Zone programming information.
4.1 DIP Switch Settings
The DIP switches select which zones will be activated by the
loop inputs. Set the DIP switches as shown in Table 1 (Page
2).
• No two DS7432s should be set the same.
• The DS7432 occupies eight zones when connected to the
control panel. The input loops of the DS7432 correspond
to the zones of the control as shown in Table 2.
