3E4291 Gallagher T20 Terminal Installaon Note | Edion 1 | August 2016
Copyright © Gallagher Group Limited
1 Introducon
The Gallagher T20 Terminal is available in a variety of variants. The variant you have purchased
determines the available funconality and supported card technologies for the terminal. For variant
details, refer to the "Terminal variants feature summary" on page 16 of this note.
The Alarms Terminal variants (C300463 and C300464) are used for alarms management only, (i.e. do
not contain a smart card proximity reader). The Mul Tech variants (C305460, C305461, C300460 and
C300461) support Gallagher mobile credenals, using Bluetooth® wireless technology.
The terminal can be mounted on a rectangular 50 mm x 75 mm (2 in x 3 in) ush box, a BS 4662 Brish
Standard square ush box, a Gallagher Mounng Block (C300930 or C300931) or any solid at surface.
The terminal sends informaon to the Gallagher Controller and acts upon informaon sent from the
Gallagher Controller. The terminal itself does not make any access decisions.
For instrucons on how to use this product, refer to the "3E3685 User Guide T2x Terminal" which can be

The Gallagher T20 Terminal is designed to operate over a supply voltage range of 9 - 16 Vdc
measured at the readers terminals. The operang current draw is dependent on the supply
voltage at the terminal.
The power source should be linear or a good quality switched-mode power supply. The
performance of the terminal may be aected by a low quality, noisy power supply.
