INSTALLATION
In order to correctly install an Orion Ex Mini-Rep, the following steps should be taken:
a) Remove the 4 screws fixing Orion Ex Mini-Rep Display to the unit’s back box.
b) Disconnect flat cable linking Orion Ex Mini-Rep Display to Interface Board.
c) Fix unit’s back box in required mounting position using the mounting holes provided. See Figure 1
d) Reconnect flat cable connecting Orion Ex Mini-Rep Main Board to Data Loop Interface board.
e) Connect Data Loop Cables to interface following instructions provided in this manual and
on appropriate data loop interface data sheet. Please also refer to Orion panel’s installation manual
for further details on how to integrate this Orion Ex Mini-Rep unit on a networked system.
f) Connect Power Supply. Orion Ex Mini-Rep are supplied by an external 24V DC, normally from the
control panel. Do not apply supply voltage until installation is complete.
g) Finally replace Orion Ex Mini-Rep cover onto 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.
All cables should be screened.
When using RS-232 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.
