MODULE TYPE CONFIGURATION (CONTROLLER OR EXPANDER)
The exibility of the A22 module allows it to be set either as a 2-door controller or 2-door expander.
Simply adjust the “TYPE” jumper to the required position (see the diagram below).
By default, each A22 is set as a 2-door controller.
• One A22 set as a controller can manage (be connected to) up to four A22 modules set as
expanders for a total of 10 doors.
• To communicate with an A22 set as a controller, use the RJ45 Ethernet connection.
• Communication between an A22 controller and A22 expansion modules is achieved using the RS485
Local Bus.

BOX TAMPER SWITCHES
Connecting the tamper switches allows the A22 to detect when the cabinet door is opened and/or when the
cabinet is removed from the wall. To install the tamper switches, see “Installing the Tamper Switches”.
To use both switches:
1. Connect one end of the supplied wire to the door tamper switch
terminal and the other end to the wall tamper switch terminal.
2. Connect the other terminal of the door tamper switch to the “TMP” terminals using the
supplied wire.
3. Connect the other terminal of the wall tamper switch to the “GND” terminals using the
supplied wire.
To use only one switch:
1. Connect one terminal of the tamper switch to the “TMP” terminals using the supplied wire.
2. Connect the other terminal of the same tamper switch to the “GND” terminals using the
supplied wire.
If you do not use the tamper switch, connect a wire between the “TMP” and “GND” terminals.

READERS AND KEYPADS
The A22 allows automatic format detection and decoding of the connected reader/keypad. When installing a
keypad with a Wiegand output, the keypad’s “D0” and “D1” wires should be connected to the same terminals
as the reader (the reader or keypad LED and buzzer outputs must be open collector).
The ATRIUM system is congured by default for the NANO, STAR and SOLAR reader models which display
a bright blue backlight in standby mode. A list of other CDVI readers and keypads is shown below. Other
popular wiegand readers and keypads are also supported. Contact us to conrm compatibility. Most readers
and keypads have built-in buzzers and LEDs. These should be connected to module’s programmable outputs
(B1, G1, R1 for READER 1 and B2, G2, R2 for READER 2). These are open collector outputs capable of sinking
100mA. Please note that the B, G and R outputs are programmed for a 7-wire reader by default. Typically, a
blue/red/green indicator on the reader will inform the card user that access has been granted (changes from
blue to green), access has been denied (changes from blue to ashing red), door is locked (from blue to brief
red) or door is unlocked by a schedule (changes from blue to brief green). Typically, the reader buzzer or an
external sounding device will inform the card user that the door has been left open after a valid access or the
door has been forced open. The functions of all these outputs are programmable through the ATRIUM software.

INPUTS
The A22 can monitor the state of up to 6 devices (12 using zone doubling) such as magnetic contacts, motion
detectors, temperature sensors, or other devices. The following are examples of the type of inputs that can be
monitored:
Magnetic Door Contact:
Permits supervision of door “status” (opened, closed, opened too long, forced open). Inputs “Door
Contact 1” and “Door Contact 2” are assigned by default as the door contact for Door 1 and Door 2
respectively. When using the default system settings, you can easily swap terminals to troubleshoot
the installation.
Request to Exit (REX):
The device used can be a push button, vertical-view motion detector or oor mat sensor. The door can
then be programmed to unlock on a REX detection. When a magnetic door contact is installed, the
system can dierentiate between a door forced open and an authorized exit. Inputs “REX 1” and “REX
2” are assigned by default for Door 1 and Door 2 REX inputs respectively.

following gure. This setup will not support WIRE CUT or WIRE SHORT
supervision, but will generate an alarm condition when the state of
the input is breached.
WIRE SHORT supervision: NO
WIRE CUT supervision: NO
Single with WIRE SHORT Supervision
(Limit of 1 Detection Device on the Input)
When using this method, only one device can be connected to
the input. The input must be connected using only one Contact (NO
or NC: programmable per INPUT in Software) as described in the
following gure. This setup will not support WIRE CUT supervision but
oers WIRE SHORT supervision and will generate an alarm condition
when the state of the input is breached.
WIRE SHORT supervision: YES (Detected as INPUT SHORT)
WIRE CUT supervision: NO
Single with WIRE CUT Supervision
(Limit of 1 Detection Device on the Input)
When using this method, only one device can be connected to
the input. The input must be connected using only one Contact (NO
or NC: programmable per INPUT in Software) as described in the
following gure. This setup will support WIRE CUT supervision but
will not oer WIRE SHORT supervision and will generate an alarm
condition when the state of the input is breached.
WIRE SHORT supervision: NO
WIRE CUT supervision: YES (Detected as INPUT CUT)

Single with WIRE SHORT and WIRE CUT Supervision
(Limit of 1 Detection Device on the Input)
When using this method, only one device can be connected to
the input. The input must be connected using only one Contact (NO
or NC: programmable per INPUT in Software) as described in the
following gure. This setup will support both WIRE CUT and WIRE SHORT
supervision and will generate an alarm condition when the state of the
input is breached.
WIRE SHORT supervision: YES (Detected as INPUT SHORT)
WIRE CUT supervision: YES (Detected as INPUT CUT)
Doubled with WIRE CUT Supervision
(2 Detection Device on the Input)
When using this method, two device
can be connected to the input. The input must
be connected using two Contacts (NO or NC:
programmable per INPUT in Software) as
described in the following gure. This setup
will support WIRE CUT supervision but not
WIRE SHORT supervision and will generate an
alarm condition when the state of one of the
input is breached.
