Introduction
The AC-020 is an advanced two door controller,
which allows you to add or delete employees
from the system, change system mode status
and change system authorization codes.
The AC-020 provides a higher level of security as
the programmer is normally placed in a secure
location while the reader sensors are remotely
located outside the controlled premises. Should a
remote sensor be attacked, entry cannot be
gained as the remote sensor only provides data
to the programmer, not authorization to release
the controlled door.
The AC-020 accepts up to 500 employees for
each door via the use of proximity cards
(provided separately) or PIN. Each employee is
issued a unique proximity card or PIN code.
Employees designated 01 to 10 are Master users
and can operate the system in both the Normal
and Secure modes of operation. Employees 11 to
500, when entered from the external reader
sensor may only operate the Controller in the
Normal and Bypass modes of operation.
It is very important to keep an accurate record of
the slot number and its assignment to each
employee. This is to enable you to add additional
employees at a later time or to delete a Prox. or
PIN code if one is lost or stolen. A record form is

AC-020 Page 12 03/02
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.

Installation
The AC-020 has been designed for easy
installation. Only a few steps are required to
install the controller.
In this section you will learn how to mount the
controller in your desired location.
You will learn how to wire the controller to its
power source, which includes attaching the
controller to a rechargeable Lead Acid battery.
Wiring diagrams are also provided for attaching
the controller to the REX button and External 26Bit Wiegand Compatible readers.
Topics in this section:
• Mounting the Controller
• Power Wiring
• Typical Lock and Option Wiring
• Reader Wiring

AC-020 Page 17 03/02
Mounting the Controller
1) Before starting, select the location for
mounting the AC-020 controller. The
controller should be installed indoors and
within the premises to be secured. It is
recommended that the controller be installed
where it cannot be seen for increased
security, but still close enough to the doors
so that the controller’s annunciator (Door
Bell, Chime & Siren) can be heard.
2) Find the mounting template label that is
provided in your AC-020 packaging, and
place it at the location that you wish to install
the controller. The template is designed to
assist you through the mounting procedure,
showing you where you drill holes in the wall
to pass the wiring through and where the
wall must be drilled to insert the controllers
mounting screws.
3) (Skip this step when attaching the AC-020 to
a US Gang Box)
Drill a hole for cables as indicated on the
wiring template. Two hole sizes are shown to
allow for the amount of cables needed,
depending on installation requirements or
adding a backup battery. Drill two screw
holes for mounting the AC-020 to the wall.

4) Remove the case screw from the controller
(see diagram below to locate the case
screw) and remove the front case from the
controller.
5) Mount the controller to the wall using the two
screws provided in the Installation Kit or use
the screws provided with your US Gang Box
when mounting to a US Gang Box.
6) Wire the controller according to the diagrams
on the next few pages.
7) Return and secure the front case using the
security screw and security tool provided in
the Installation Kit.
You now have mechanically installed the
controller.
