The Gallagher T21 PIV Reader is available in four variants. The variant you have purchased determines
the supported card technologies for the reader, refer to the topic "Reader variants feature summary"
below. The reader's contact slot reads PIV card data, for PIV PIN validaon.
The reader is compable with the Gallagher Command Centre soware vEL7.50 (or later). The reader
connects to a Gallagher Controller 6000 High Spec PIV (C305101). The reader sends informaon to the
Controller and acts upon informaon sent from the Controller. The reader itself does not make any
access decisions
The reader can be mounted on a rectangular 50 mm x 75 mm (2 in x 3 in) ush box, a BS 4662 Brish
Standard square ush box, or any solid at surface.
For instrucons on how to use this product, refer to the "3E3685 User Guide T2x Terminal" which can be
downloaded from here: hps://security-support.gallagher.com
Reader variants feature summary
The available funconality and supported card technologies for each variant are shown below.
• 5 x 25 mm No.6 self tapping, pan head, Phillips drive xing screws
• 5 x 40 mm No.6 self tapping, pan head, Phillips drive xing screws
• 1 x M3 Torx Post (T10) Security screw
2.2 Power supply
The Gallagher T21 PIV Reader is designed to operate over a supply voltage range of 9 - 16 Vdc
measured at the readers terminals. The operang current draw is dependent on the supply
voltage at the reader.
The power source should be linear or a good quality switched-mode power supply.
The performance of the reader may be aected by a low quality, noisy power supply.
2.3 Cabling
The Gallagher T21 PIV Reader requires a minimum cable size of 4 core 24 AWG (0.2 mm2)
stranded security cable. This cable allows the transmission of data (2 wires) 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 specied to operate at
9 Vdc, for good engineering design it is recommended that the voltage at the reader should be
approximately 12 Vdc.
HBUS cabling topology
The HBUS communicaons protocol is based on the RS485 standard and allows the reader to
communicate over a distance of up to 500 m (1640 ).
The cabling between HBUS devices should be done in a "daisy chain" topology, (i.e. A "T" or
"Star" topology should not be used between devices). Should "Star" or "Home-Run" wiring be
required, the HBUS 4H/8H Modules and the HBUS Door Module allow mulple HBUS devices to
be individually wired to the one physical locaon.
The end devices on the HBUS cable should be terminated using 120 ohms resistance. To
terminate the Controller, connect the supplied on-board terminaon jumpers to the Controller.
To terminate the Gallagher T21 PIV Reader, connect the orange (terminaon) wire to the green
(HBUS A) wire. Terminaon is already included at the HBUS Module, (i.e. each HBUS port is
permanently terminated at the module).

* The matching of wire sizes to equivalent wire gauges are only approximate.
** Recommended cable types for opmal HBUS RS485 performance.
Notes:
• Shielded cable may reduce the obtainable cable length. Shielded cable should be
grounded at the Controller end only.
• If other cable types are used, operang distances and performance may be reduced
depending on the cable quality.
• The recommendaon for opmal performance is up to 20 x T21 PIV Readers can be
connected to one Controller. Of these 20 readers, up to 4 could be congured for alarm
zone (or fence controller) management.
A reader is congured for alarm zone management when it has either Alarm Zones
congured on the Alarm Zones properes page or items congured upon its mimic panel.
3 Distance between readers
The distance separang any two proximity readers must not be less than 200 mm (8 in) in all direcons.
When mounng a proximity reader on an internal wall, check that any reader xed to the other side of
the wall is not less than 200 mm (8 in) away.
ATTENTION: This equipment contains components that can be damaged by
electrostac discharge. Ensure both you and the equipment are earthed before
beginning any servicing.
The Gallagher T21 PIV Reader can be mounted on:
• a vercal, rectangular 50 mm x 75 mm (2 in x 3 in) ush box
• a BS 4662 Brish Standard square ush box
• any solid at surface
The recommended mounng height for the reader is 1.1 m (3.6 ) from the oor level to the centre
of the reader. However this may vary in some countries and you should check local regulaons for
variaons to this height.
Notes:
• Consideraon should be given to the installaon environment when using Gallagher mobile
credenals, as the Bluetooth® wireless technology read range may be reduced.
• Installaon on metal surfaces, parcularly 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 surface.
• When mounng on a ush box, the corner screws must be used as well as the ush box screws.
Without corner screws the top of the product is vulnerable to separaon from the wall.
1. Ensure the building cable has been run out through the ush box.
If you are not mounng to a ush box, use the reader bezel as a guide, to drill all ve holes. Drill
the 13 mm (1/2 inch) diameter centre hole (this is the centre hole for which the building cable
will exit the mounng surface) and the four corner xing holes. Ensure the centre hole allows
the cable to run freely out through the mounng surface, so that the reader facia can clip into
the bezel.
Note: There is no room for the building cable to be squeezed into the reader bezel. The building
cable must remain within the ush box or wall cavity.
2. Run the building cable through the reader bezel.
3. Secure the bezel to the ush box using the two screws provided.
When securing the bezel to a vercal, rectangular ush box, use the 6-32 UNC screws provided.
When securing the bezel to a BS 4662 Brish Standard square ush box, use the M3.5 screws
provided.
4. Drill pilot holes for the four corner xing holes and the tamper tab. Secure the bezel to the
mounng surface using the four corner xing screws provided. Secure the tamper tab (located
in the bezel) to the mounng surface using the remaining xing screw provided. It is important
the four corner xing screws are used to ensure the reader is ush with and ght against the
mounng surface.
Note: It is strongly recommended that you use the screws provided. If an alternave screw is
used, the head must be no larger nor deeper than that of the screw provided.
