Aritech Reliance XR Installation
Power Requirements
The Aritech Reliance XR range of products are to be only powered from an approved
Australian power unit source.
The Aritech Reliance XR is designed to be used with a 16 VAC 1.5 Amp 24 VA transformer
which is included with Aritech Reliance XR panel kits. If more current is required, upgrade
to a 16 VAC 3 Amp 48 VA transformer and/or add NXG-320 Smart Bus Power Supplies.
Cable Requirements
The system RS-485 communication bus is used to connect keypads, input, and output
expanders to the Aritech Reliance XR.
• Only VW-1 rated cable is to be used for installation of these products.
• 800 m total cable run on system.
• Max. 800 m from remote device to Aritech Reliance XR control panel.
• Max. 32 devices plus panel.
Shielding
The shielding of all shielded cables used in the system should only be connected at one side
to one common earthing point in a building. If a shielded LAN cable is routed via more than
one plastic device, the shielding from incoming and outgoing cable must be connected.
Termination Links
Put a jumper across TERM on the panel and the furthest device to ensure correct RS-485
termination and avoid communication issues with signal reflection, etc.
