Installation Note | Gallagher T12 Reader
Installation
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 used.
The recommended mounting height for the reader is 1.1m (3.6ft) 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.
Ensure the building cable has been run out through the flush box.1.
If you are not mounting to a flush box, use the drill template at the back of this
installation note as a guide, to drill all five holes. Drill the 13mm (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.
Run the building cabling through the reader base.2.
Secure the base to the flush box using the two M3.5 screws provided. It is 3.
important the base of the reader is flush with and tight against the mounting
surface.
If you are not mounting to a flush box, secure the base to the mounting surface
using the four fixing screws provided.
