WebSwitch™ Users Manual
2.2.4.1 Input Connection (Model XRDI-WS3P only)
Two discrete inputs are provided which can be connected to dry contact sensors or switches. Sensors
can be used for monitoring alarm conditions such as access or thresholds. Alternatively, if local control of
the outlets is needed, switches can be connected to the inputs and the unit can be configured such that
they control the outlets.
Connect one terminal of sensor or switch to the input terminal (Input 1 or Input 2) on WebSwitch Plus™.
Connect the other terminal to the ground terminal on WebSwitch Plus™. When contacts are closed the
input is connected to ground and the input is considered to be “ON”.
