OPERATION
DS-SIP
is designed for use with ANY IP or Cloud PBX System. It can connect to ANY
Network Point. The IP Address of
DS-SIP
is then set up as an Extension and it can be
called if required from Any Handset on the same PBX system.
A ‘Hot Dial Extension Address’ is set up on the PBX system by the Network
Administrator, to determine where Intercom calls should be directed. The ‘Hot Dial
Extension Address’ is also programmed into
DS-SIP
using the supplied program.
Then when a visitor at the door or gate presses the call button on your NATCOMM
Door Phone,
DS-SIP
will immediately go ‘Off Hook’ and Dial the Hot Dial Extension
Number. At the same time, DS-SIP will generate a ‘Ring Back’ tone to the Door
Phone Intercom so that the visitor hears that they are being connected.
A PBX user can then answer the Door Phone Intercom call and will be immediately
connected to the visitor so that they can communicate. Communication is Loud and
Clear. The Volume of the Door Phone can be increased or decreased via the supplied
program. The Hang Up tone detection circuit will automatically terminate the Intercom
call after the user hangs up
If you have a LOCK MECHANISM fitted, you can open a gate or door lock during a
call to allow your visitor to enter, by simply pressing
* *
on your telephone keypad.
LOCK RELAY 2
If you use the SECOND LOCK CONTROL FACILITY fitted, you can also open an
ALTERNATIVE gate or door lock during this call, by pressing
*
2 on your telephone.
This command will release Gate Lock 2 until you Hang Up the telephone.
Pressing *3 can also close the second internal relay and leave it closed.
Pressing *4 can also open the second internal relay and leave it open.
The SECOND LOCK RELAY option can alternatively be used to START and STOP
another Device such as a VIDEO CAMERA, DISPLAY MONITOR, RECORDER or to
TURN ON and then TURN OFF a 12V LIGHT or a 115V Light (if a separate 115V
relay that is also supplied and installed by a technician or electrician).
The Other Device will be SWITCHED ON (or Activated) as soon as the Call Button is
pressed on the supplied Door Phone and will SWITCH OFF, 01-99 seconds after the
Door Phone call has terminated, as programmed (see pages 13-14)
.
The Second Relay can also be used to signal other equipment that a Door Phone
Intercom call has been initiated.
