Installing the Access Control Interface Unit
The following installation procedures are limited to the installation of the Access Control Interface Unit
and the wiring to the various readers, the door strike (or Keylok), and the RS-485 bus. Manufacturer's
installation instructions for the various card/key readers, door strikes, etc. come with those devices.
Always follow these instructions when installing or working on these items.
The installation procedure entails installing the ACIUs and their on-board batteries and making
connections to the RS-485 bus to allow the batteries to charge. During this charging time, you can
install the card/key readers, electric strikes, Keyloks, etc. Once the batteries have fully charged, power
down the control unit and connect the readers, strikes, etc. to the ACIU. Then use the construction
card/keys to check that each electric strike or Keylok functions properly, and make mechanical
adjustments where necessary.
The Summary of Access Control Card/Key Readers Table, shown later in this section, provides
important information concerning the various card/key readers, including user operation, required
reader DIP switch settings, and instructions for jumper settings for E11 on the ACIU.
Application Guidelines
Use the following guidelines when planning an installation:
•
All access control applications require a separate ACIU for each door.
•
All readers, except for the Marlok Keyreader and Keylok, can be used on both sides of a door, and
share the same ACIU.
•
Reserve the first 99 user ID codes for people who must use an operating panel.
•
When using an access-controlled perimeter front door, always make sure that there is another
perimeter door having a mechanical lock for gaining access. In this way, if there is a problem with
the door release mechanism or the ACIU, someone with the key can enter the other door and then
open the front door to let people in.
•
Where general access to an unprotected lobby is required, and there is no concern for scheduling, a
card/key reader can be used with an ACIU that does not have any BA groups assigned to it. This
will allow access to the lobby for all persons with valid card/key codes, while requiring all others
(visitors, etc.) to be buzzed in.
If access to the lobby is to be limited to certain working hours, assign the lobby reader to a BA
group that does not have any BA points. Then assign a schedule to that BA group. All persons
having limited access must be programmed with a close-only privilege. All persons requiring
round-the-clock access must be programmed with either open or irregular open privilege.
•
Install a card/key reader near an operating panel to facilitate the enrolling of new cards/keys.
Installation Guidelines
Use the following guidelines when installing the ACIU:
•
Do not use a mag stripe card on a Wiegand reader. It may corrupt the code on the mag stripe card.
•
Each ACIU must receive a minimum of 12.5V from the RS-485 bus. Otherwise, the on-board
battery will not charge and there will not be any power for releasing the door strike. If necessary,
add a power supply to ensure that this voltage will be available.
•
Maximum current for the electric door strike = 550mA.
•
Make certain that the length of cable between the ACIU and its associated reader and door strike
does not exceed 150 feet.
•
The ACIU must not be subjected to temperatures below 32°F (0°C) or above l20°F (49°C).
•
Include each ACIU in the System Layout Diagram of the FOCUS 200 PLUS System, indicating the
BA group(s) that will be accessed via the ACIU.
