1.0 Introduction

The DS7465i Input/Output Module operates with
compatible multiplex systems. It has a Form “C” relay
(the output zone) that is programmed to activate from
several different system events. The DS7465i can
also monitor normally open (NO) or normally closed
(NC) contacts and report their status as a multiplex
address to the control system. Up to 60 DS7465i
Modules can be used on the DS7400Xi. Use up to 20
DS7465i Modules per bus on compatible fire alarm
control panels (FACPs). When installing the DS7465i
with a D8125MUX, refer to the D8125MUX Operation

and Installation Guide (P/N: F01U034973) and the
D9412GV2/D7412GV2 Approved Applications
Compliance Guide (P/N: F01U003639).

2.0 Installation

These installation instructions assume the control
panel is installed and in proper working condition.

Perform the following procedure to install the
DS7465i:

You must program the control panel and set
the DS7465i address switches before the

Figure 1: Removing the Cover

DS7465i can operate.

1. Program the DS7465i and the control panel

as described in the control panel’s reference
guide.

Disconnect power to the control panel
before running wires and connecting the
DS7465i.

2. To remove the cover of the DS7465i, place

your thumb directly above the lip of the
DS7465i and press in and up. Refer to

.

3. To remove the DS7465i circuit board from the

base, press the circuit board retainer tab and
pull the circuit board up and out of the base.
Refer to

When used in a fire system, NFPA 72
prohibits this product from sharing a
communications bus with non-fire devices.

Hold the circuit board by its edges to avoid
damaging it.

4. Insert the wiring through the wire entrance of

the base.

5. Mount the base using the supplied screws.

Surface-mount the DS7465i near the devices
it controls or monitors.

6. Return the DS7465i circuit board to the base.

After any programming or hardware
change, do a functional test of the system
as required by local codes.

The input zone is power limited and
supervised. The output relay must only
be used on power-limited circuits.

Fire applications require NO contacts on
the input zone.

Connect wiring to the DS7465i as shown in Figure 3
through

Figure 5.

The input loop is designed to monitor NO
or NC dry contacts. It is supervised using
a 47 kΩ end-of-line (EOL) resistor. If
using the input loop as a fire alarm input,
order the Multiplex Resistor Kit (P/N:

28010).
