Installing the box lock allows to secure the box from
unauthorized access. Installation procedure:
1. Remove the box door knock-out.
2. Insert the lock in the hole.
3. Slide the “U” metal part into the lock
groove to secure the lock in place.
Alternatively or complementary to the box lock,
the box may be secured by xing the cover to
its base using screws.
However this should be done only once the
installation is completed.
1. Use the 4 screws supplied to secure
the box cover to its base as shown
in the following picture.

5] WIRING DIAGRAM
Out of the box the A22K is ready for IP connectivity, fty (50) A22K per account. If you have more than one
A22K controller per account, one must be set as the “Master” controller to manage the others. These forty
(49) others are dened as “Sub-Controllers”.
The exibility of the A22K module allows it to be set also as an “Expander”. Up to four (4) A22K set as
an “Expander” can be connected to the RS485 Local Bus (orange connector) of a “Master” or
“Sub-Controllers”. ATRIUM give you a total of 500 doors system (100 doors connected IP + 400 doors
connected RS485). Simply adjust the “Module Type” jumper setting as shown below.

A22K set as “Controller”
is connected on a
network (LAN or WAN) and
manages all the modules
connected to its RS485 port.
Up to 50 A22K set as
“Controller” can be
connected per site for a
maximum of 500 doors.
When there is more than one
controller per site, one must
be designated as the “Master
Controller”. It will be the link
between the software (or web
server) and all modules.
See the ATRIUM software
manual or web server guide
on how to designate an A22K
controller as the “Master
Controller”.

Connecting the tamper switches allows the A22K 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.
