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 Volt age For Operation: 8 VDC peak

• Wiring: Refer to the reference guide for the panel’s multiplex
expansion module for multiplex wiring 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) A WG , quad (4-wire) cable. Do not use shielded
or twisted pair cable.

• For fire applications, #18 A WG (1.2 mm) wire is required.

If using separate powered detectors (other than
smoke detectors) with a DS7400 Series 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.

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.
