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.

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.

Events and Event Actions
Tamper Event
A Tamper Event is triggered if the controller
detects that a reader has been disconnected or
loses power, and can also be triggered if the case
of the reader is removed.
Possible Tamper Event Actions
Reader sensor wire is disconnected from the AC020 DOOR 1 / DOOR 2 reader input terminal
Tamper data signal is received from DOOR 1 /
DOOR 2 reader sensor
To clear a Tamper Event enter a valid code or
Lock Strike code which will open the door locker
output of the Door that caused the tamper event.
For example, tamper condition at Door 2 during
Secure status, entering Door 2 Lock Strike Code
1 (default 0852) from external reader will not
clear tamper because it is not permitted to open
the door during this operation mode. However,
applying the same code from the AC-020
keyboard will clear tamper output as well as
opening Door 2 Lock Strike and stopping the
siren (assuming no Door 1 tamper).

AC-020 Page 29 03/02
Request to Exit (REX) Button
The REX button must be located inside the
premises to be secured and is used to open the
door without the use of a proximity card or PIN
code, it is usually located in a convenient
location, e.g. Inside the door or at a receptionist’s
desk. The function of the REX button depends on
whether the Lock Strike Relay is programmed for
Fail Safe Operation or Fail Secure Operation.
The door chime in the BLD40 does not sound
when the REX button is used to open the door.
1) Fail Secure Operation: From the moment
the REX button is pressed, the door will be
unlocked until the ”Lock Strike Release
Time” has passed. After this time, the door
will be locked even if the REX button has not
been released.
2) Fail Safe Operation: From the moment the
REX button is pressed, the door will be
unlocked until the REX button is released,
plus the ”Lock Strike Release Time.” In this
case the ”Lock Strike Relay” only begins its
count down once the REX button has been
released.

AC-020 Page 30 03/02
Siren Sound
Siren sound triggered by Door 1 or Door 2 tamper
is generally stopped by clearing the tamper of
that door. However, if the tamper condition at the
other door exists, one is required to clear that
tamper event as well, in order to stop the siren.
Either way, the siren may stop on its own if the
pre-programmed siren time has elapsed.

For Tamper Alarm:
• If the Tamper Alarm is required, enter 1-9

an unassigned proximity card is enrolled
at an occupied slot, the AC-020 will
generate a long beep and wait for
another slot number to be entered. The
card at the current slot location must be
erased first, before a new code is
programmed on that slot number. The
same rules apply for PIN based
employee codes.
