The Gallagher T11 Reader is designed to be mounted on ver cally orientated

electrical ﬂ ush (gang) boxes, or any solid ﬂ at surface. However installa on on metal

surfaces, par cularly 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 moun ng height for the reader is 1.1 m (3.6 ) from the ﬂ oor

level to the centre of the reader device. However this may vary in some countries

and you should check local regula ons for varia ons to this height.

Ensure the building cable has been run out through the ﬂ ush box.

If you are not moun ng to a ﬂ ush box, use the drill template at the back of this

installa on note as a guide, to drill all ﬁ ve holes. Drill the 13 mm (1/2 inch)

diameter centre hole (this is the centre hole for which the building cable will

exit the moun ng surface) and the four ﬁ xing holes.

Run the building cabling through the reader base.

Secure the base to the ﬂ ush box using the two 6-32 UNC screws provided. It is

important the base of the reader is ﬂ ush with and ght against the moun ng
