From Internal User's View (Survey of Functions)
Calling to 2N® Helios
You call the appropriate extension and 2N® Helios makes the call and gives a
confirmation tone after two rings (or as pre-programmed). Now you can speak and
control the 2 switches, program 2N® Helios (see later), and listen to what is going
on outside and speak to the calling party if desired.
Door opening
2N® Helios contains a switch to which an electric lock can be connected (not included
in this pack). This switch can be telephone keypad controlled using a (digital)
password in two ways as shown in the default password 00 example below:
or
The switch activation time can be programmed once the switch is enabled this will also
automatically terminate the call in the next 30 seconds.
Note
 If the Automatic Multiple Number Dialling with Confirmation or the Silent
Automatic Multiple Number Dialling with Confirmation mode is selected
and the password starts with digits 1 to 5, an asterisk must always be
used.
 You Must enter every digit in the password within five seconds (or as pre-
programmed) to avoid 2N® Helios from hanging up.
Switch 2 activation (light, e.g.)
The second switch (if an additional switch is installed) can be controlled in the same
way.
Switch 2 synchronisation
Switch 2 can also be used to delay the opening of another door. Once the switch 2
delay timeout is programmed, the second switch is synchronised automatically with
the first one, the delay being 1 – 25 seconds.
Switch activation signalling (for both switches)
After the correct password is entered, the switch is activated and you can hear the
confirmation signal on your telephone. You can now speak (e.g. say: “The door is
open“) or listen (to the door-opening sound, etc.) until the switch is deactivated. Upon
deactivation, you can hear the storing signal (see the Signals Overview).
