INSTALLATION
In order to correctly install an ORION MINI-REP, the following steps should be taken:
a)
Remove the 4 screws fixing ORION MINI-REP V2 front cover to the unit’s back box.
b)
Disconnect flat cable linking ORION MINI-REP V2 mainboard to Interface Board.
c)
Fix unit’s back box in required mounting position using the mounting holes provided.
d)
Reconnect flat cable connecting ORION MINI-REP V2 Main Board to Data Loop Interface board.
e)
Connect communication wiring to interface following instructions provided in this manual together with the chosen
interface manual. Refer to ORION panel’s installation manual for further details about operation.
f)
Connect Power Supply. ORION MINI-REP V2 requires 24V DC supply voltage, which can be derived from the control
panel auxiliary supply output. Do not apply supply voltage until installation is complete.
g)
Place ORION MINI-REP V2 cover onto the unit's back box using the four previously removed screws.
Before powering up the unit, verify that all connections are correctly made and that there are no open or short circuits on any
of the interconnecting wires used for both supply and data transmission.
All connections should be performed with all elements of the Fire Detection System unpowered.
The Repeater should be located where access to the internal components is not restricted and where the unit is not exposed
to high levels of moisture, vibration and shock.
WARNING:
Observe ESD precautions when handling the PCBs.
All cables should be screened.
WARNING:
Cable screen’s should only be connected at one point to the physical Earth
connection in order to avoid current loops.
When using RS232 or RS485 interfaces, only use cables recommended for this communication media. As a general rule,
cables used for LAN (Cat 5) are suitable for this type of interfacing technology as they are widely available and offer
excellent data transmission characteristics. Other signal cables for RS485 communication (twisted pair) can also be used:
