BOX TAMPER SWITCHES

ETHERNET
Connecting the tamper switches allows the A22K to detect when the cabinet door is opened and/or when the
PORT
cabinet is removed from the wall. To install the tamper switches, see "Installing the Tamper Switches".
To use both switches:

terminal and the other end to the wall tamper switch terminal. LOCAL

READERS AND KEYPADS

The A22K 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 configured by default for the K1, NANO, STAR and SOLAR reader models which display a
bright blue backlight in standby mode. Other popular Wiegand readers and keypads are also supported. Contact
us to confirm 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.
Reader LED status:
Standby: LED indicator is steady blue
Access granted: LED indicator changes from blue to green
Access denied: LED indicator changes from blue to flashing red
Door unlocked by a schedule: LED indicator 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.
