The front panel of the
K-1900-8-IP Series
phone is mounted using security Torx screws to help prevent intruders from
removing the panel and accessing the on board door strike/gate control relays. For applications requiring additional security,
a Viking model
RC-4A
remote relay controller can be used. The relay controller is mounted securely inside the building and
connected to the same LAN as the
K-1900-8-IP Series
phone. The on board door strike relays would not be used in this
case as the
KK-1900-8-IP Series
phone will send an encrypted message to the
RC-4A
to activate its relays which control
the door strikes/gates.
Up to 4
K-1900-8-IP Series
phone’s can communicate with one
RC-4A
allowing you to securely control four entrances.
When using a
RC-4A
for remote relay control, the
K-1900-8-IP Series
phone’s relays should be set to “External” in the PC
programming.
