Introduction
The Gallagher SMB T11 Reader can be configured as an arming reader or access reader.
The reader allows users to arm, disarm, or request access at a locked door with a smartphone
(via Bluetooth
®
or NFC) or a Gallagher SMB Key Tag.
Connections
The HBUS communications protocol allows a single reader to communicate over a distance
of up to 500 m (1640 ft) from the controller, when using data only in a single CAT5E cable.
Cabling should be a minimum size of 0.2 mm
2
(24 AWG). 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).
Connect the reader tail to the building cable. If the reader is the last device on the run,
terminate the reader by connecting the Orange wire to the Green wire.

Distance between readers
The distance separating any two readers must not be less than 200 mm (8 inches) in all
directions. When mounting the reader on an internal wall, check that any reader fixed to the
other side of the wall is not less than 200 mm (8 inches) away.
