4.1 Function Description
From External User's View (Visitor)
Like normal Doorbells,
2N® Helios
buttons are provided with labels the visitor finds
the appropriate button (e.g. Mr. Smith) and presses it this activates
2N® Helios
to
then dial the number pre-programmed for under that button, the visitor can then hear
the ringing tone from the loudspeaker and the required (Mr. Smith„s in this case)
telephone is ringing. If the 2N® Helios unit is connected to a telephone system you
may be able to tag the port that 2N® Helios is connected to so that you can see on
the ringing phone that it is
2N® Helios
that is calling. When the called party answers
the call, the visitor and tenant can speak to each other and If an electric lock is
connected to
2N® Helios
, the called person can open the door by entering the correct
password on the telephone keypad to activate the door or barrier. When the caller
hangs up,
2N® Helios
detects the PBX or analogue line tone and hangs up too.
2N®
Helios
also hangs up when it “hears” the busy tone or if the call takes more time than
pre-programmed to connect. You can pre-program the amount of time that you have
to speak into the microphone however when you are reaching the programmed time
the unit gives a warning tone 10 seconds before hanging up so that the called party
can extend the call if required.
Note
If the visitor presses another button during the call, 2N® Helios hangs up
for a few seconds before dialling the new number.
If a button is pressed that has no number stored within it 2N® Helios
picks up the line, sends a refusal tone (refer to the Signals Overview) and
hangs up.
If the visitor presses the same button during the call, 2N® Helios may
hang up (can be programmed to stop this feature if required).
The above mentioned rules are only applied if the Automatic Multiple
Number Dialling mode is OFF. For this special mode refer to the Automatic
Multiple Number Dialling section.
