** Recommended cable types for optimal HBUS RS485 performance.
*** Not applicable for Gallagher mobile credential reader installations.
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, operating distances and performance may be reduced
depending on the cable quality.
•
HBUS allows up to 20 readers to be connected to a single cable. Each reader requires at
least 9 Vdc to function correctly. The cable length and the number of readers connected
will have an impact on the voltage at each reader.

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

Installation
ATTENTION: This equipment contains components that can be damaged by
electrostatic discharge. Ensure both you and the equipment are earthed before
beginning any servicing.
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
surface.
Note: Consideration should be given to the installation environment when using Gallagher mobile
credentials, as the Bluetooth® wireless technology read range may be reduced.
The recommended mounting height for the reader is 1.1 m (3.6 ft) 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.
1.
Ensure the building cable has been run out through the flush box.
If you are not mounting to a flush box, use the reader bezel as a guide to drill all five holes. Drill
the 13 mm (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.
