Reading Heads
There
are currently three reading heads available for proximity
cards and tags:
904.102.17 is a naked reader.
It has the same size and uses the same mounting template
as a 90 mm magnetic reader and it can be used to replace
the magnetic reader in PROX+, TRAX+, TRAX+P, EnTRAX
terminals.
The other two heads are usually connected to a 914.003.20
motherboard to create much simpler access control units.
Both are suitable for outdoor use and emit a "beep"
at each reading. They come equipped with a fixed length
cable.
904.103.17 is a compact unit in
a plastic mould enclosure with an adhesive sticker to
cover the heads of the screws used to mount the unit
on the wall. It is equipped with a green LED which signals
when power is on and when a successful read has taken
place.
It provides an excellent reading distance considering
the size of its antenna.
It is particularly suitable for use with the MAX 914
functioning on-line with a PC or Master PROX+ .
It can also be used as a second read head on a PROX+.
904.101.17 is enclosed in a solid
machine-worked aluminium casing with satin finish, like
the one used on the magnetic card readers. Compared
to the 904.103.17 it has the advantage of having two
LEDs, one green, one red, which
can be driven by the access control terminal to which
the RF reader is connected (a 914.003.20 for example).
A successful read is signalled acoustically while the
two LEDs are used to display the status of the access
control unit, a valid transaction, or the programming
status of the terminal.
