From the six wires of the RJ11 cable only the two central wires are used. These two
wires are distributed pin-to-pin. The signals transmitted through these wires comply
with the RS-485 norm, which permits it to reach distances of up to 1.5 kilometers.
Go to section 3 if your device has a single CLESA module.
2) Chained CLESA modules connection
A flat cable ending in RJ-11 pin-to-pin connectors is used to connect chained CLESA
modules. The connectors must be connected to the CON2 connector of the first chain
module and to the CON1 connector of the next module, respectively.
3) Input devices connection
We can connect a relay, a button or a switch (usually open or usually close,
supervised or unsupervised), a voltage source, or an electric current source to the
inputs. Each input has a microswitch to configure the type of input to be used. Table
1.2 shows the possible combinations.
Relay / button /switch usually open, unsupervised
This is the simplest case. The device detects activity when a contact, that is usually
open, is closed.
Relay / button / switch usually closed, unsupervised
This is similar to the previous case, but here the inactive level is a closed contact and
must be activated when the contact is open.
