FOCUS 200 PLUS Installation and Setup Guide
•
Users can be assigned varying degrees of access to the BA group(s).
•
A total of 255 access control users can be programmed, of which 99 can also have use of the
operating panels.
•
A user with janitor privilege may shunt alarms on Janitor points in all BA group(s) with card/key.
Basic Operation Using Card/Key Reader
Each door being used for access control requires:
•
A card-or key-reading device installed.
•
An electric door-releasing mechanism installed.
•
Both the reader and door-releasing mechanism wired to the ACIU.
•
The card or key's unique code enrolled into the database of the control unit.
When a card/key is used at the reader, the following sequence of events occurs before the person is
permitted entry:
Step
1

The card/key code for the various users can be assigned locally from an operating panel or can be
downline loaded. See the ID Codes section for the details of the procedure using an operating panel.
Physical Description of ACIU
The ACIU fits into a separately ordered 472352 Housing Unit that is also used for a quad PID module.
The following are important items on the board (see Figure 10-1):

Action
The reader interprets the code on the card/key and forwards this data to the ACIU.
When interrogated by the control unit, the ACIU sends the code that was read.
The control unit then processes the information to determine whether to permit access.
Some of the questions that must be satisfied during this processing are:
•
Does the code exist in the control unit database?
•
Does the person have access to all of the BA groups assigned to the ACIU?
•
Are the BA group(s) turned on in the area being accessed?
•
Does the person have an open privilege?
•
Is the time of day within the open schedule?
•
Does the person have an irregular open privilege?
If the control unit determines that it is OK for the person to gain access, it signals the
ACIU, which then uses its battery to provide the power for operating the door strike or
other lock-releasing mechanism, thereby allowing the person to open the door.
Purpose
Used for making connections to the RS-485 bus.
Used for connecting the reader.
Used for powering the door-releasing mechanism.
There is space for a separately ordered 12V 0.8 AH standby battery that
connects to a polarized connector on the circuit board.
Insert only if the ACIU is located at the end of the RS-485 bus.
Used for setting the ACIU communication address on the RS-485 bus.
Remove jumper if you are using an on-board battery.
Leave the jumper intact if it is powering a 12V device. Remove jumper if it
is powering a 5V device. Connect a standard 3k EOLR across TB3-1 and
TB3-2 if it is not powering a door releasing mechanism.
