Setting inputs, outputs, and jumpers
Digital inputs
The device has 2 inputs and 2 outputs. The 2 inputs can be used either as
digital dry contacts or supervised contacts. The type of contacts used is
defined from the configuration of the device performed by the EBI. By
default, the inputs are set as supervised.
Usually the IN1 is dedicated to the door contact.
Usually the IN2 is dedicated to the push button (request to exit).
However, the inputs can also be used as general purpose inputs.
The typical connection for digital dry contacts is shown in
Figure 22
.
Temaline recommends that you establish an electrical environment where
the cables are well separated, even at short runs, especially to the power
cables or external cables which can be essentially subjected to interference
or lightning.
Use a twisted-pair cable for the contact cables. Make sure that the cables
correspond in size to the norms indicated in “Wire characteristics” on
page 10.
Max contact resistance = 25 Ohm
