Anti-tamper / anti-pulling switches
Please refer also to “Tamper Switch” section.
These switches are activated as soon as there is enough pressure applied on the
terminal against the wall. They are deactivated as soon as this pressure is not big
enough, e.g. when the terminal is pulled out of the wall.
When the switches are deactivated, the MorphoAccess® SIGMA Extreme Series
terminal acts as required by the related configuration key (see MorphoAccess® SIGMA
Extreme Series Administrator / User Guide for key configuration description):
Ignore the event (default): useful during normal maintenance operations.
Send an alarm message to the Central Access Controller, through the usual channel
of the access control result messages (Wiegand, DataClock, RS485, Ethernet or Wi-
Fi™). An alarm switch (relay contact) is directly available on block terminal «tamper
switch pins». Please refer to “Wiring overview” and to “Tamper Switch” sections.
Generate an audible alarm signal with the speaker and an alert message on the
screen.
