DS7457iE Single Zone
Input Module
Features
▶ Power-limited and supervised input zones
▶ Compact enough to fit within most backboxes and
enclosures
▶ Address settings through DIP switches
The DS7457iE is a Single Zone Input Module designed for
intrusion applications. It has a dual-resistor supervised
input zone for connecting normally-open (NO) or normally-
closed (NC) contacts. The DS7457iE controls the contacts
using 22kΩ+47kΩ resistors for serial dual end-of-line (EOL)
wiring. Each DS7457iE operates with compatible multiplex
expansion modules and occupies one multiplex zone
address on the system.

Wiring Considerations
Refer to the intended control panel’s installation guide for
multiplex wiring requirements. The recommended wiring to
the control panel is four-wire 0.8 mm cable. Do not use
shielded or twisted pair cable.
Note The length of the wiring connected to the
protection loop (and tamper loop) must be
less than 76 m.
