u Power-limited and supervised input zones

u Compact enough to fit within most back boxes and

enclosures

u Address settings through DIP switches

The DS7457i Series Single‑zone Input Modules
includes the DS7457i, the DS7457i-CHI, 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 and the DS7457i-CHI are
designed for intrusion applications while the DS7457iF
is designed for fire applications.

Multiplex Modules D8125MUX Multiplex Bus Interface

DS7430 Multiplex Expansion Module

DS7436 Multiplex Expansion Module

The DS7457i Series Modules require a multiplex
expansion module to connect to the control panels.

Wiring Considerations

Maximum Impedance: 4.05 Ω at +20°C (+68°F) nominal

Distance (approximate) Size

76 m 0.65 mm

193 m 1.02 mm

250 ft 22 AWG

600 ft 18 AWG

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.

Notice

If used in fire applications, 18 AWG wire is
required.
