1.5.4.- Repeaters
1.5.4.1.- Installation
The repeater must be fixed on a vertical wall face. The side slots must be left free for heat to escape.
The dimensions and the pre-drilled holes for cable entry are shown in the following diagram.

. Repeater box
The LYON control panel allows up to 15 repeaters to be connected to it. For this, a 4-wire
connection of 1.5 mm
2
wires (two for power supply and two for communication, for the RS485 line) must be
used. The two wires for the RS485 line are to be connected from the control panel’s back panel to the
terminals of each control panel labelled as “REPETITOR” in the front label. The two power supply wires are
to be connected from the 30V output of the control panel’s power supply to the terminal labelled as 30 V of
the corresponding repeaters. The repeaters must be connected as shown in figure 11.
Up to 3 repeaters can be connected to the Lyon control panel’s power supply 30V output. From
4 to 15 repeaters must be fed from the 30V output of an auxiliary power supply (FAE).
For connecting the repeaters, both the communication and 30V power supply cables must be
2 x 1.5 mm HALOGEN-FREE SCREENED BRAIDED CABLE, up to a maximum cable length of
1200 metres.
On completing the installation, a 120 Ohm resistor must be connected between the terminals A and B
in the “REPETITOR” connector of the last repeater connected.
DISCONNECT the 110~230V MAINS voltage and the BATTERIES
before handling the inside of the control panel or the repeaters.
1.5.4.2. Operation and Configuration
The repeaters display all the information about alarms, disconnections, relay actuations and faults.
Once the repeaters have been connected, they must then be configured in the control panel by
entering the number of each repeater to be configured. To do this, follow this sequence in the control panel:
