Installation Instructions
for the
DS9432/DS9432B Eight Input Remote Module
1.0 Description
The DS9432/B 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 DS9400 Series Fire Alarm
Control/Communicator.
2.0 Specifications
• Control Panel Requirements: The DS9432/B is designed to
work with the Detection Systems DS9400 Series Fire Alarm
Control Communicator. Version 2.0 software or higher is required
in the DS9400. The DS9400 can support up to 30 DS9432/B
modules. One DS9431 Multiplex Expansion Module is required
in the system to use the DS9432/B Eight Input Remote Module.
•Current Draw (from option bus power): 8 mA Standby and Alarm
•Current Draw (from multiplex bus loop): 10 mA Standby and
Alarm
•Total Current Draw for Battery Standby Calculation and Alarm:
18 mA Standby and Alarm
• Minimum Bus Voltage For Operation: 8 VDC peak
•Wiring: Refer to the DS9400M Reference Guide (P/N: 44578) for
the panel’s multiplex expansion module for multiplex wiring
requirements. The length of the wire connected to the loop inputs
on the DS9432/B must be less than 250 ft. (76 m) per loop.
• The recommended minimum wiring to the control is standard #18
(1.2 mm). Do not use shielded or twisted pair cable.
For UL Listed fire applications, minimum #18 AWG (1.2
mm) wire is required.
3.0 Installation
P3 of the DS9432 is for European applications only. Do
not put a jumper here.
P2 of the DS9432 allows the tamper switch to be bypassed with a
jumper when testing or servicing.
Remove jumper P2 when testing or servicing has been
completed.
3.1 DS9432 Installation
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 DS9431 in the control enclosure
and from the remote devices to the DS9432.
Connect wiring as shown in Figure 2.
Be sure all wiring is unpowered before routing.
If the wiring is to enter through the rear of the enclosure, open the
DS9432's rear wire entrance. If the wiring is to run along the surface
of the enclosure, open the DS9432's surface wire entrance. See Figure
2.
3.2 DS9432B Installation
The DS9432B will come partially preassembled with the circuit board
attached to the mounting skirt.

Attach Mounting Skirt Here
Figure 1: DS9432B
Select a mounting location for the DS9432B.
Using the enclosure as a template, mark the mounting holes on the
mounting surface and make an opening for the unit’s wiring.
Next, attach the mounting skirt (with the circuit board attached) to
the enclosure (hardware provided). Then complete all wiring (see
Section 4.0).
Once installation and wiring is completed, attach the enclosure
cover and secure with the screws (provided).

5.0 Programming
The DS9432/B occupies eight multiplex point addresses
when connected to the control panel.
5.1 System Programming
Refer to the System Programming section in the DS9400M
Reference Guide (P/N: 44578) for zone programming information.
5.2 DIP Switch Settings
The DIP switches select which points will be activated by the loop
inputs. Set the DIP switches as shown in Table 1.
• No two DS9432/Bs should be set the same.
• The input loops of the DS9432/B correspond to the points of the
control as shown in Table 2.
