The Gallagher T20 Reader

The Gallagher T20 Reader is a smart card proximity reader. The reader can be

installed as either an entry reader or an exit reader.

The reader can be mounted on a rectangular 50 mm x 75 mm (2” x 3”) flush box, BS

4662 British Standard square flush box, or any solid flat surface.

The Mifare reader reads: Mifare DESFire EV1, Mifare Plus and Mifare Classic cards.

The Multi Tech reader reads: Mifare DESFire EV1, Mifare Plus, Mifare Classic and 125

KHz cards.

The reader sends information to the Gallagher Controller and acts upon information

sent from the Gallagher Controller. The reader itself does not make any access

decisions.

The reader uses the Cardax IV communications protocol to communicate with the

Gallagher Controller. Refer to the “Connections” topic later in this note, for details

regarding Cardax IV Reader connections.

ATTENTION: This equipment contains components that can be damaged

by electrostatic discharge. Ensure both you and the equipment are earthed

before beginning any servicing.
