The front panel of the
K-1775-IP
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 mounting securely inside the building connected to the same LAN as the
K-1775-IP
. The
on board door strike relays would not be used in this case as the
K-1775-IP
will send an encrypted
message to the
RC-4A
to activate its relays which control the door strikes/gates.
Up to 4
K-1775-IP’s
can communicate with one
RC-4A
allowing you to securely control four
entrances.
When using an
RC-4A
for remote relay control the
K-1775-IP’s
relays should be set to “External” in
the PC programming.
