The Cardax FT Intelligent Door Terminal (125 Series)
The Cardax FT Intelligent Door Terminal (125 Series) is a "remote" proximity
reader with text display and an inbuilt Intercom, designed to connect only to
Cardax FT Controller 5000s.
It can be installed as either an entry and/or exit reader and the Intercom enables
communication with the console operator.
The IDT has a back-lit keypad and an inbuilt Liquid Crystal Display (LCD).
The LCD can display both text and graphics to aid the cardholder.
The IDT sends information to the Cardax FT Controller and acts upon
information sent from the Cardax FT Controller. The IDT itself does not make
any decisions.
The "Cardax FT Prox Reader and IDT Cover" can be fitted over the IDT to
prevent the IDT being damaged by vandal attack and to increase protection
against harsh weather. Refer to the "Prox Reader and IDT Covers" Installation
Note (part number 3C4589).

Before you begin
Shipment contents
Unpack the Cardax FT IDT (125 Series) and check the shipment contains the
following items:
• 1 x Cardax FT IDT (125 Series) base
• 1 x Cardax FT IDT (125 Series) facia (pre-assembled with Processor,
Display and Keypad PCBs)
• 1 x Interconnect PCB
• 1 x Cardax FT Intelligent Door Terminal (125 Series) Installation Note
(part number 3E0054)
• 1 x cable assembly
• 4 x self tapper pan-head fixing screws
• 4 x screw caps
Note: Once the reader is installed, you require a special tool to open the
Cardax FT IDT (125 Series). Part number C41608 is a kit containing three
delatching tools, of which one is the tool required to remove the cover off the
Cardax FT IDT (125 Series).
Power Supply Requirements
The Cardax FT IDT (125 Series) requires a well regulated power source with
good output filtering. Any "noise" on the power supply may reduce card read
range.
Power required for the Cardax FT IDT (125 Series) is 13.6 V DC (± 15%) with
current at 300mA per reader. This means that the voltage at the reader
terminals, with the reader operating, should be at least 11.6 V DC. It is
recommended you target a minimum of 12 V DC.
Cabling
Prior to installing a Cardax FT IDT (125 Series), the building cabling (RS485
and power) must have been carried out. For further cabling details, refer to
Chapter 2 of the "Cardax FT Installation manual".
To avoid voltage drop in cable runs, it is recommended to run separate DC
power and communications cabling. However, a single cable run is possible as
long as the voltage and current do not drop below the required levels.
EMI Cable Shields
To comply with CE, C-Tick and FCC requirements, and improve noise
suppression, an EMI Cable Shield (ferrite core) should be applied to the cable,
with three turns of the cable running through it. Position the EMI Cable Shield
as close to the entry point of the IDT as possible.

Mounting
RS485 Communications
High quality twisted pair communications cable with low capacitance typically Category 5 (CAT5) cable is used for communications cabling.
DC Power
The maximum recommended length of the DC power cable is dependant on the
diameter of the conductor and the current drawn by the IDT.
Note: The Cardax FT IDT (125 Series) has been designed to metric
specifications therefore any imperial measurements provided are approximate
only.
The Cardax FT IDT (125 Series) is designed to be mounted on any solid flat
surface.
However, the card read range is reduced slightly when mounted on or near
metal surfaces.
Height
The recommended mounting height (from the floor to the centre of the IDT)
for the Cardax FT IDT (125 Series) is 1100mm.
Check your local regulations for any variation to this recommended height.
