From External User's View (Visitor)
Like normal Doorbells,
Helios
buttons are provided with labels the visitor finds the
appropriate button (e.g. Mr. Smith) and presses it this activates
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 Helios unit is connected to a telephone system you may be able to tag the port that
Helios is connected to so that you can see on the ringing phone that it is the
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
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,
Helios
detects the PBX or analogue line tone and
hangs up too.
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.
Notes:
•
If the visitor presses another button during the call, Helios hangs up for a few
seconds before dialling the new number.
•
If a button is pressed that has no number stored within it 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, 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.
