NOTE 2!
Even if the fiber modem have rs-485 connections
it’s allways recommended to use it on rs-232 mode and
use CodiNet- coverter between the fiber modem and
the panel if the lentgh of the copper cable on the
rs-485 connection is more than ~100m
Picture 7. Max. two modem pairs between two panels
1. Disconnect all power from the control panel.
2. Connect the RS485 serial communication wires to
the
RS485 terminals (INFO) and
System1 terminals (RS485 type) and
System2 terminals (RS485 type) as follows
Signal wires to terminals T/R + and T/R – and GND.
(Note that shield wire of the cable can not be
connected to the GND terminal).
The shields of the cables may not be connected to
the metal part (earth) of the cabinet directly. The
shields must be connecter through the parallel
connected capacitor and varistor as follows
(because long distances may cause big differences
in earth potential). Loosen three screws of the
backplate. Install the small circuit board from the SA
package under the screws and tighten the screws
and connect the shield to the terminals.
3. Connect the RS232 serial communication
conductors to the RS232 terminals as follows:
The control panel transmitter wire to terminal TxD
The control panel receiver wire to terminal RxD.
GND wire (not shield) to terminal GND.
Connect the shield directly to the metal part (earth)
of the cabinet.
4. Start the control panels: first visible panels and
then seeing panels
5. If the control panel gives an earth leak indication, line fault (one of S1 and S2 is not functioning) or
communication fault (either of S1 and S2 is not functioning), press the “BUZZER SILENCE”- button and
disconnect all power from the control panel. Repair any fault and restart the control panel.
6. If the control panel has been configured, the operation of serial communication should be tested
(remember that a fire or fault also activates fire or fault alarm devices and alarm routing equipment).
