Control wired alarm devices from the VIAS app

SA203 Alarm bridge

The SA203 3in/3out bridge module is equipped
with three sets of signal input terminals and
three sets of relay output terminals. Its primary
function is to convert wired products into the
wireless U-Net protocol through SA203. This
allows for the integration of wired alarm systems
into the U-Net environment, enabling the system
(Gateway) to monitor input signals, control relay
outputs, and establish trigger conditions for
input signals to manage relay outputs.

This product utilizes the U-Net wireless two-way
communication control method and can
connect to the Gateway for smart home
integration and functionality.

Relay input

3 sets of signal input terminals support NC/NO dry
contacts connected to the alarm system.

Relay output

3 sets of relay output terminals support SPDT type
with their own NC-COM-NO terminals connected to
the alarm system.

Notifications

Notifications will be sent when a signal input is
triggered by the alarm system.
