Brief overview
With the Gigaset HC450, the door inter-
com becomes an integral component of
the cordless telephone system. It supports
two-way speech using any registered
cordless telephone which means that the
house telephone no longer has to be per-
manently located in the entrance area.
The Gigaset HC450 door intercom is suita-
ble for practically all single-family resi-
dences, including those that only have
abell.
Main features
uTwo-way speech with callers to the
door using the cordless telephone –
including handsfree
uIntuitive operation via the handset's
softkeys (open door, activate entry
light)
uEasy configuration using the menu on
the handset
uForwarding to external numbers
uEase of installation and registration
with the Gigaset system
uReplacement of the old bell button
with the door intercom – the existing
cabling is generally adequate for
installation
uSupport for existing bell and standard
door openers
uConfiguration options for the second
bell key (separate door call to specific
handset, activation of entry lighting,
same function as first bell key)
Gigaset Home Control
"Gigaset Home Control" is a standard that
allows you to control
uhousehold appliances
ulights and blinds
ualarm systems
uheating and air conditioning systems
and
udoor intercoms such as the
Gigaset HC450
from a Gigaset cordless telephone.
The full functionality of the HC450 door
intercom (opening the door from the
handset, forwarding calls to an external
number and configuring the system) is
available in conjunction with Gigaset cord-
less telephones that support "Gigaset
Home Control". A list of all compatible
devices can be found in the appendix and
on the Internet at
www.gigaset.com/customercare.
If you are operating the door intercom
with a standard DECT handset that is not
fully compatible and only supports the
GAP standard, only the "intercom" func-
tion is possible.
(GDECT / GAP is the transmission protocol
for cordless phones. This allows handsets
of one manufacturer to be operated on
the base station of a different manufactu-
rer. In this case, however, operation is
restricted to the telephones' basic func-
tions.)

In common with the HC450 door inter-
com, all other products certified for
"Gigaset Home Control" can be easily
installed without additional cables and
networked with the Gigaset cordless tele-
phone at the push of a button.
"Gigaset Home Control" thus grows with
your needs.
All compatible devices fea-
ture the "Gigaset Home
Control" logo, making them
very easy to identify.

Range of applications
Assigning the two doorbell keys
The HC450 door intercom has two door-
bell keys, each of which can be assigned
different settings.
Top doorbell key:
The top doorbell key activates a connected
external bell. At the same time, an internal
call is initiated to a specific or to all hand-
sets.
Bottom doorbell key:
uThe bottom doorbell key can initiate
another internal call (other handset or
other ringer tone) in addition to the
external bell.
uIts function can also be set identically
to the top key or
uThe entry lighting can be activated
when the key is pressed. This requires
the lighting system to be connected to
the HC450 control unit. If the bottom
doorbell key is being used as a
"lights key", it cannot function
as a "doorbell key".
Call diversion
If call diversion is activated for the door
intercom, the door call will then be
diverted to the external number. The call
diversion relates to the top doorbell key.
The call diversion can be controlled in dif-
ferent ways: If the occupier is at home he/
she sets "Status: Home", which means that
the internal handset will be called first. If
no-one answers, the call will then be
diverted. If "Status: Away" is set, the door
call will immediately be forwarded to an
external number.
Example:
In the Smith family's house, handset no. 1
rings when the top doorbell key labelled
"Smith family" is pressed. Handset no. 2
belonging to the son will only ring when
the bottom doorbell key labelled "Mat-
thew Smith" is pressed. The Smith family
has activated call diversion. If no-one from
the family is at home, then the call will be
forwarded to the father's mobile phone.

Door opener, bell and entry lighting
The following devices, which are not
among the items supplied, can be con-
nected to the HC450 and operated:
Door opener:
The door can be opened from
the Gigaset handset or, in the
case of a forwarded call, from
a remote location. To do this, a
standard door opener must be
connected (not supplied). The
voltage pulse (12 V alternating
voltage) for opening the door
is supplied by the HC450.
Bell: An existing bell will be con-
nected to the HC450.
Door light:
A light circuit (e.g. the entry
lighting) can be switched on
from the handset and if appli-
cable via the bottom bell key
for between 1 and 90 seconds
or also operated in pulse mode.
The connection to the floating
contact (230 V, 10 A) must be
undertaken by a qualified elec-
trician.

extended by means of a repeater
placed between the base station
and control unit.
uMount the HC450 control unit at a suit-
able location along the junction wire
between the bell button and bell.
It is recommended that you mount the
unit near the bell transformer. This is
normally located in the fuse box. Any
adjustment required to the fuse box
must be undertaken by a qualified
electrician.
uTo ensure that a suitable mounting
location is selected, familiarise yourself
with the location of the cabling before-
hand. Watch out for the cabling
between the bell button, the bell trans-
former and the bell. Lay the cables so
that nobody can walk on or trip over
them. Before finally mounting the
control unit, check the placement of
the unit with temporary cabling by per-
forming a function test (control unit
can register with the base station, sta-
ble operation possible with adequate
connection quality from the handset to
the HC450 door intercom).
uYou should also refer to the mounting
instructions for the HC450 door inter-
com (see p. 7).
uThe control unit must not be installed
in a fuse box or metal housing.
uThe control unit must not be installed
near air conditioning systems, in areas
with strong sunlight or in dusty
environments.
uThe control unit must be protected
from the direct influence of water
and chemicals.
uAreas with strong magnetic fields
(transformers, electric motors, high-
voltage lines) must be avoided.
uCables must not be connected or dis-
connected or the HC450 control unit
installed during a thunderstorm.
uWatch out for electrical, water or gas
lines in the wall if mounting the control
unit on the wall.
Mounting
If necessary, loosen the screws from the
casing. Pull the cover downwards to
remove it.
Mark the positions of the two drill holes on
the wall. Drill two holes suitable for 6 mm
wall plugs. Screw the upper screw into the
wall plug and mount the casing by fixing
the upper mounting hole onto the screw.
Screw the casing into place using the
lower mounting hole.
For laying the cables, a multi-core commu-
nications cable is recommended with a
wire profile of 0.6 mm.

Version 4, 16.09.2005
Setting up the
Gigaset HC450 door
intercom system
Once you have installed your HC450 door
intercom system, you can set up the door
intercom at your convenience using a
compatible handset. Before you can do
this, however, you must register the door
intercom system with the base station.
Registering with the base station
Make sure that the control unit is con-
nected to a power supply. If the LED on the
HC450 control unit is flashing, it means
that it is not yet connected with the base
station.
uSet the 4-digit system PIN of your base
station to "0000" if necessary (refer to
the manual for your telephone).
uPress the registration/paging key on the
base station for approx. 3 seconds. The
registration/paging key is located on
the right beside the charging cradle.
uGo over to the control unit and press
the button on the control unit with a
thin object such as a paper clip within
20 seconds (see illustration on p. 11).
The LED on the control unit will light up
continuously once it has been regis-
tered (the LED will return to flashing
when a call is underway between the
door intercom and base station). If reg-
istration does not take place despite a
number of attempts, reduce the dis-
tance between the base station and
control unit (the base station can be
disconnected from the telephone net-
work to do this) and/or briefly discon-
nect the control unit from the power
supply before commencing registra-
tion.
uFollowing successful registration,
"Intercom" will appear in the list of inter-
nal users. This preset name can be
changed via the handsets (refer to the
user guide for the handset).
Setting functions
Starting programming

Changing the display language
You can view the display texts in different
languages. The languages available
include English, German, Italian, Dutch
and French.
Call up the menu for the settings
(see p. 13):
Note:
Change the system PIN of the base station
once more (refer to the manual for your tele-
phone). This ensures, among other things,
that only designated handsets can be regis-
tered with the base station.
Note:
The menu for changing the display language is
called up automatically during startup
(see p. 13).

Operation with automatic
call diversion
When a call is diverted, all the functions
can also be used remotely from a mobile
phone, for example to ask the postman to
leave a parcel with a neighbour.
Switching between "Status: Home"
and "Status: Away"
If you have entered an external number
for call forwarding, you can switch
between "Status: Home" and "Status: Away".
The call diversion only ever relates to the
top doorbell key.
uWith "Status: Home", the defined inter-
nal user will be called when a call
comes in from the door intercom. If the
"Automatic Call Diversion" function is
activated and the internal user does not
answer the incoming call within the set
time (see "Setting the internal and
external call time for incoming calls
from the door intercom", p. 16), the
incoming call will be diverted to the
defined external number.
uWith "Status: Away", the call coming in
from the door intercom will be diverted
to the defined external number.
Calling the door intercom internally:
uInitiate an internal call and
select the internal user
"Intercom".
§Edit§ Press the display key if neces-
sary to change the mode.
aPress and hold (return to

recorded announcement that is repeated
at regular intervals. You now have the
option of accepting the call or terminating
the process:
1Press the 1key to accept the
call.
#Press the hash key #to end
the call.
The recorded announcement does not
offer the option to open the door, how-
ever this option will be available to you if
there is a door opener connected to your
door intercom.
OPress the 9key to open the
door.
~Enter the 4-digit PIN.
If you enter the PIN correctly, you will hear
a recorded announcement and the door
will be opened. The voice connection will
still be active; you can terminate it by
pressing the hash key #.
If you did not enter the PIN correctly, you
will hear a recorded announcement:
"Enter PIN". You can then either re-enter
the PIN or re-establish the voice connec-
tion with the caller by pressing the star
key *. To terminate the voice connec-
tion, press the hash key #.
If the conversation lasts longer than the
set external call duration, a recorded
announcement will sound 10 seconds
Note:
The incoming call cannot be diverted to a fur-
ther telephone if the external number is
engaged when the call comes in from the door
intercom or if an answering machine answers.
The door intercom will not, however, be con-
nected with the trunk line in this case.
Note:
It is only possible to open the door from an
external telephone if a separate PIN other than
0000 has been set up beforehand for the door
intercom (see p. 14).
Warning:
If you want to use the door opening function
from outside, the front door cannot be locked.
