enclosed for your reference to assist you with
your record keeping.
The AC-020 is capable of learning both PIN
codes (keyboard based codes - 4 digits code)
and Prox. Codes (codes received from proximity
card reader). The Controller has two reader
inputs, one for Door 1 and one for Door 2. These
readers are to be located outside the restricted
area. Readers need to be Wiegand 26 bits
interface type, and may be a Proximity card
reader (for Prox. Codes), Keyboard (for PIN type
codes) or combined PIN/PROX reader. Please
refer to Accessories – page 60.
The PIN reader can be used for programming the
system, in addition to its regular duty of codes
entry. During normal use, PIN codes that are
employee codes can be entered only from reader
sensor, while Special Codes may be entered
either from AC-020 or from the reader.
