DS7457i Series Single Zone
Input Modules
Features
▶
Power-limited and supervised input zones
▶
Compact enough to fit within most back boxes and
enclosures
▶
Address settings through DIP switches
The DS7457i Series Single Zone Input Modules includes the
DS7457i and the DS7457iF. Each model has a supervised
input zone for connecting normally-open (NO) or normally-
closed (NC) contacts. The DS7457i Series supervises the
contacts using 47 kΩ end-of-line(EOL) resistors. Each
model operates with compatible multiplex expansion
modules and occupies one multiplex zone address on the
system. The DS7457i is designed for intrusion applications
while the DS7457iF is designed for fire applications.

Refer to the intended control panel’s installation guide for
multiplex wiring requirements.
The recommended wiring to the control panel is quad (four-
wire) cable. Do not use shielded or twisted pair cable.
Note If used in fire applications, 18 AWG wire is
required.
