Installaon
The Gallagher T20 Reader can be mounted on:
• a vercal, rectangular 50 mm x 75 mm (2” x 3”) ush box
• a BS 4662 Brish Standard square ush box
• any solid at surface
The recommended mounng height for the reader is 1.1 m (3.6 ) from the 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.
Notes:
• 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 surface.
• When mounng on a ush box, the corner screws must be used as well as the
ush box screws. Without corner screws the top of the product is vulnerable
to seperaon from the wall.
• The reader cannot be mounted on a mounng block.
1. Ensure the building cable has been run out through the ush box.
If you are not mounng to a ush box, use the reader base as a guide, to drill
all 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 corner xing holes. Ensure the centre hole allows the cable to run
freely out through the mounng surface, so that the reader facia can clip into
the base.
Note: There is no room for the building cable to be scrunched into the reader
base. The building cable must remain within the ush box or wall cavity.
2. Run the building cable through the reader base.
Note: If the reader has already been connected to the building cable, you can
pass the facia through the base. Great care must be taken to avoid scratching
the screen and keypad when passing the facia through the base.
3. Secure the base to the ush box using the two screws provided. When
securing the base to a vercal, rectangular ush box, use the 6-32 UNC screws
provided. When securing the base to a BS 4662 Brish Standard square ush
box, use the M3.5 screws provided.
4. Drill pilot holes for the four corner xing holes. Secure the base to the
mounng surface using the four corner xing screws provided. It is important
the four corner xing screws are used to ensure the reader is ush with and
ght against the mounng surface.
Note: It is strongly recommended that you use the screws provided. If an
alternave screw is used, the head must be no larger nor deeper than that of
the screw provided.
