A22K
High Security Access Control 2-Door Module
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.
