Lyon box
Cofem Digital Detection System
allows to connect up to 15 control panels in a network, by
connecting 2 wires of 1,5 mm
2
(RS485 communication line). The two wires of the RS485 line will
be connected from the “CONRED” indication in the back panel of each control panel. Such
connections are shown in Figure 13.
Power is held in each control panel separately. Each control panel will be connected to
the 110~230V mains and its corresponding set of batteries.
The communication cables connection between control panels will be made with
cable
2 x 1,5 mm twisted shielded halogen free, up to a maximum cable length of 1200 meters.
On completing the installation, a 120 Ohm resistor must be connected between the terminals A and B
in the “CONRED” connector both the first and the last control panel connected.
DISCONNECT the 110~230V MAINS voltage and the BATTERIES
before handling the inside of the control panel or the repeaters.
