OPERATION
DS5 Plus
is designed for use with a PBX Extension.
The Extension should be programmed with a ‘Hot Dial Extension Address’.
Then when a visitor at the door or gate presses the call button on your NATCOMM
Door Phone,
DS5 Plus
will immediately go ‘Off Hook’ and the PBX will Dial the Hot
Dial Extension Number. At the same time, DS5 Plus 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 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
(Optional)
If you use the Optional 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).
