Events and Event Actions
Tamper Event
A Tamper Event is triggered if the controller
detects that a reader has been disconnected or
loses power, and can also be triggered if the case
of the reader is removed.
Possible Tamper Event Actions
Reader sensor wire is disconnected from the AC-
020 DOOR 1 / DOOR 2 reader input terminal
Tamper data signal is received from DOOR 1 /
DOOR 2 reader sensor
To clear a Tamper Event enter a valid code or
Lock Strike code which will open the door locker
output of the Door that caused the tamper event.
For example, tamper condition at Door 2 during
Secure status, entering Door 2 Lock Strike Code
1 (default 0852) from external reader will not
clear tamper because it is not permitted to open
the door during this operation mode. However,
applying the same code from the AC-020
keyboard will clear tamper output as well as
opening Door 2 Lock Strike and stopping the
siren (assuming no Door 1 tamper).
