Gallagher T20 Reader
Installation
The Gallagher T20 Reader can be mounted on:
•
a vertical, rectangular 50 mm x 75 mm (2" x 3") flush box
•
a BS 4662 British Standard square flush box
•
any solid flat surface
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.
Notes:
•
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.
•
When mounting on a flush box, the corner screws must be used as well as the
flush box screws. Without corner screws the top of the product is vulnerable
to seperation from the wall.
•
The reader cannot be mounted on a mounting block.
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 base 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 corner fixing holes. Ensure the centre hole allows the cable to run
freely out through the mounting 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 flush 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 flush box using the two screws provided. When
securing the base to a vertical, rectangular flush box, use the 6-32 UNC screws
provided. When securing the base to a BS 4662 British Standard square flush
box, use the M3.5 screws provided.
4.
Drill pilot holes for the four corner fixing holes. Secure the base to the
mounting surface using the four corner fixing screws provided. It is important
the four corner fixing screws are used to ensure the reader is flush with and
tight against the mounting surface.
Note: It is strongly recommended that you use the screws provided. If an
alternative screw is used, the head must be no larger nor deeper than that of
the screw provided.
