Gallagher T12 Reader
This equipment contains components that can be damaged by electrostatic
discharge. Ensure both you and the equipment are earthed before beginning
any servicing.
Gallagher T12 Multi Tech Readers only: Using dual technology 125/Mifare
cards with Gallagher T12 Multi Tech Readers may cause both card technologies
to be read, resulting in double card badges and unusual reader feedback.
Gallagher strongly recommends against using dual technology 125/Mifare
cards with Gallagher Multi Tech Readers for sites running pre-Command Centre
v7.00 software (due for release 2nd half, 2011). From Command Centre
v7.00, a site may specify which technology a Multi Tech reader should read
off a dual technology card.

The Gallagher T12 Reader
The Gallagher T12 Reader is a smart card proximity reader. It can be installed
as either an entry reader or exit reader. It can be mounted on a BS 4662 British
Standard square flush box.
The reader can read Mifare DESFire EV1, Mifare Plus and Mifare Classic cards.
The Multi Tech variant can also read 125Khz cards.

Installation Note | Gallagher T12 Reader
The reader sends information to the Cardax FT Controller and acts upon information
sent from the Cardax FT Controller. The reader itself does not make any access
decisions.
The Gallagher T12 Reader uses the “Cardax IV Reader” communications protocol
to communicate with the Cardax FT Controller.

Shipment Contents
Check the shipment contains the following items:
1 x Gallagher T12 Reader facia assembly•
1 x Gallagher T12 Reader base•
1 x M3 Torx Post Security screw•
2 x M3.5 Phillips drive fixing screws•
Power Supply
The Gallagher T12 Reader is designed to operate over a supply voltage range of
9 - 16Vdc measured at the reader terminals. The operating current draw is dependant
on the supply voltage at the reader. For the Standard variant at 12Vdc the current
draw is 89mA (standby). During card read, beeper and LED activity, the current will
momentarily reach 124mA (peak). For the Multi Tech variant at 12Vdc the current
draw is 88mA (standby) and will momentarily reach 140mA (peak).
The power source should be linear or a good quality switched-mode power supply. The
performance of the reader may be affected by a low quality, noisy power supply.
Cabling
The Gallagher T12 Reader requires a minimum cable size of 4 core 24 AWG
(0.2mm
and power (2 wires). When using a single cable to carry both power supply and
data, both the power supply voltage drop and data requirements must be considered.
Although the reader is specified to operate at 9Vdc, for good engineering design it
is recommended that the voltage at the reader should be approximately 12Vdc.

The distance separating any two proximity readers must not be less than 200mm
(8 inches) in all directions.

Installation
The Gallagher T12 Reader is designed to be mounted on a standard British electrical
flush box, or any solid flat surface. However installation on metal surfaces, particularly
those with a large surface area will reduce read range. The extent to which the range
is reduced will depend upon the type of metal used.
The recommended mounting height for the reader is 1.1m (3.6ft) from the floor level
to the centre of the reader device. However this may vary in some countries and you
should check local regulations for variations to this height.
Ensure the building cable has been run out through the flush box.1.
If you are not mounting to a flush box, use the drill template at the back of this
installation note as a guide, to drill all five holes. Drill the 13mm (1/2 inch)
diameter centre hole (this is the centre hole for which the building cable will
exit the mounting surface) and the four fixing holes.
Run the building cabling through the reader base.2.
Secure the base to the flush box using the two M3.5 screws provided. It is 3.
important the base of the reader is flush with and tight against the mounting
surface.
If you are not mounting to a flush box, secure the base to the mounting surface
using the four fixing screws provided.
