DS7461i Single Zone Input Module
1.0 Description
The DS7461i is a Single Zone Input Module designed to operate with compatible multiplex systems. It provides a supervised input
zone for connection of conventional normally open or normally closed inputs. Each DS7461i occupies one multiplex zone address on
the system. The DS7461i connects to the DS7430, DS7436 Multiplex Expansion Modules or the D8125MUX Multiplex Expansion
Module. For additional DS7461i installation information, refer to the
D9412GV2/D7412GV2 Approved Applications Compliance Guide
(P/N: F01U003639).

3.0 Programming
Refer to the control panel's installation guide for multiplex zone (point) programming information.
Refer to
Section 6.0
on page 3 for switch settings.
4.0 Installation
After any programming or hardware change, do a functional test of the system as required by local codes.
These instructions assume that the control panel is installed and in proper working condition.
The control panel must be programmed and the DS7461i address switches must be set for the DS7461i to operate.
•
Program the control panel as described in the control panel's reference guide.
Disconnect power to the control panel before routing wires to connect the DS7461i.
