Introduction
Description
A bellfree video door entry system consists of a door panel, positioned at the entrance of a
building, apartment stations and other telephones, placed inside of the building for the
convenience of the occupants and a power supply and controller which are usually located
inside an electrical cupboard. The door panel comprises of a two-way speech unit, a
camera, an LED display and sixteen push buttons –which are used by a visitor to initiate a
call. The apartment station, which rings in response, allows a two-way hands free
conversation (a touch is required to initiate the conversation and end the conversation)
whilst the caller can be observed through the integral display. The operator can selectively
allow visitors access to the building by touching a pad on the apartment station and so
electrically releasing the door.
The bellfree digital video door entry system is suitable for any building or entry point
addressing a quantity of flats where a standard panel would be larger or more expensive;
this is typically from 16 flats upwards.
The bellfree digital system is supplied with a dedicated door controller, for each entrance,
and a video controller for every four apartment stations. The basic system supports 1
apartment station per address, and up to 3 extension apartment stations (more with
additional power supplies). Multiple entrances can be supported with the addition of one
panel and one door controller for each entrance.

Basic System Operation
Panel Controls
Number and Letter Buttons
The numbers 0 to 9 are used to enter numbers. The letter button >A enters letters
beginning with A and each press advances through the alphabet, while the letter button <Z
does the reverse starting with Z. For example pressing >A three times will give C then
pressing <Z once will give B, or starting with Z; pressing 5 times will give V and then
pressing >A twice will give X.
The call button is used to call flats or acts as a bell button calling the reception phone.
The cancel button cancels the current entry leaving a blank display.
The reception (AKA Porter or Concierge) button calls a pre-defined phone dedicated to
that location.
The door or Trades button is used to gain direct access either directly or via a code.
Call sequence
When the resident‟s address is entered followed by the call button the addressed
apartment station will ring and its blue pickup / view lamp will flash, highlighting the
pickup and view symbols. The apartment station will continue to ring for up to 30
seconds or until the resident responds by touching the view symbol (see silent viewing
below) or the pickup symbol. After using the pickup symbol the resident can freely
converse with the visitor whose image is now displayed on the apartment station; at the
same time the green lock symbol will flash to highlight the lock function.

The call may be terminated by touching the pickup symbol again or more usually by
touching the lock symbol first to allow the visitor access through the entrance; the speech
and picture will persist for a further 3 seconds while the door is being released.
Silent viewing
When the apartment station is ringing the resident can touch the view symbol to answer
the call instead of the pickup symbol; this will stop the apartment station ringing and
enable them to view the visitor for up to 60 seconds or until the lock symbol is touched to
release the door. Silent viewing can be „normalised‟ at any time by touching the pickup
symbol and conversing with the visitor as described above.
Apartment Station Controls
The diagram in the introduction shows the apartment station and its controls. The controls
are adjusted by touching the end of the slider and sliding the finger up and down. The
default setting is ringer volume halfway and contrast slider fully down.
Auto Display
When „Auto Display‟ mode is selected the picture will come on while the apartment station
is ringing, otherwise the picture will only come on when the call is answered. Auto Display
mode is usually pre-selected at installation and generally only one apartment station per
flat should be set in this mode (see „Extension Apartment Stations‟ below).
Ringer Mute
The resident can mute the ringing sound in the apartment station when they do not wish to
be disturbed. Ringer mute is activated by touching the mute symbol on the apartment
station, which then illuminates in red as a reminder. Touching the mute symbol a second
time will disengage the mute function. Ringer Mute only stops the audible ring, but the
blue ring lamp will still flash and all other functions work normally. Ringer mute will
continue for the pre-set time even if a call is answered.
During installation it is possible to set a time limit for the mute function in various values
from 2 minutes up to 10 hours or indefinitely. When this time period has elapsed the mute
function will automatically disengage. Default timeout is never (See „mute timer‟, page 25).
Door Status Indication
The green lock lamp on the apartment station will illuminate to warn the resident that a
door has been left open following a call. This feature requires a door monitor contact to be
fitted.
Call Privacy
Once a call has been made from an entrance panel only the apartment station(s) which is /
are ringing may answer the call. Once the call is answered another apartment station will
not activate (including extensions of the active apartment station).
User Activation (CCTV Mode)
User activation is a feature of the bellfree 1 way system and is not available on digital
systems. User activation is generally not recommended on larger systems as the
conflicting demands of residents and callers can result in confusion and erroneous fault
reports.

BF Apartment Station Digital Entry System
PD–166 Issue 1 Installation and Operating Manual Page 8 of 48
Cameras
The door controller has the capability of using one or two cameras, for instance a second
panel camera for DDA or a „third party‟ „CCTV‟ camera located to offer a different entrance
viewpoint. Touching the view symbol will alternate the view between camera 1 and
camera 2 (if enabled).
Note. The camera to controller wiring has termination options which allow for connections
to other video equipment. See the Camera sharing diagram on page 41 for details.
Extension Apartment Stations
Additional apartment stations may be added to each „flat‟. The number of extensions is
limited only by power supply considerations. All apartment stations for that „flat‟ will ring
when called however typically only the master unit will display a picture while ringing.
Once the master or extension apartment station is „picked-up‟ the picture will display on
that unit alone.
Lock Type
The door controller supports both fail-secure and fail-safe locks including magnetic locks of
up to 1A rating. The lock time may be programmed between 1 and 99 seconds. (See
„Lock Release Operating time‟ and „Lock Type‟ on page 20.
Exit Button and Fire Switch
An input is provided for an exit button, which can be installed on the inside of the door and
allow residents to exit freely. Momentary operation of this button will operate the lock
release for the programmed lock time. A Fire switch or other override device may use the
same input to hold the door open indefinitely. Note. Fail secure locks must be
continuously rated.
Trades Facility
The trades facility is accessed by pressing the door button. An optional time clock may be
used to allow one function during the programmed time(s) and another at all other times.
These functions can be: –unlock the door, ask for an entry code or ignore the button
press.
There are 2 entry codes available, a residents code and a tradesman‟s code.
DDA Functionality
The bellfree digital video system has a range of options for entrance panels to help meet
the requirements of the Disability Discrimination Act (DDA), including Illuminated Tactile
buttons and reassurance tones to indicate apartment station ringing and door released.
Contact your sales representative for further details.
Multiple Entrances
The bellfree system allows multiple entrances to be catered for by the addition of a door
controller and entrance panel for each entrance and additional power supplies.
Gate and Block Systems
Sites with two or more blocks sharing one or more site entrances are catered for with our
BSSW Gate controller. The blocks can then work independently but will receive calls from
the shared entrance.
For further details see the “bellissimo and Bellcall Manual Gate and Block (PD-120)”.

●Battery back-up power supply, Model 840 (12V 4A).
●DDA panels (Contact sales for further information).
Entrance Panel –Important Note
Careful consideration should be given to the location of the entrance panel to ensure the
best possible lighting conditions for the camera. In general strong back lighting of the
subject (by the sun and sky) should be avoided, as the contrast between foreground and
background may be too great for the camera. The field of view should contain as little of
the sky as possible, particularly if south facing. If a backlit situation is unavoidable,
additional lighting may be necessary to illuminate the caller and avoid a dark outline image
(silhouette). A light coloured or reflective surface around the panel will redirect backlight to
illuminate the caller.
Door Controller
The door controller and power supply should be wall-mounted in a convenient cupboard or
other protected environment with available mains power. Cable length to the entrance
should be less than 50m. The door controller for the second and subsequent entrances
may be situated in the same location, or to meet the 50m requirement may be situated in
another location. Power supplies may be shared between door controllers placed in the
same location, but controllers in separate locations must be separately powered.

BF Apartment Station Digital Entry System
PD–166 Issue 1 Installation and Operating Manual Page 10 of 48
Video Controller
The video controller(s) and power supply(ies) should be wall-mounted in a convenient
cupboard or other protected environment with available mains power. Cable length to the
apartment station should be less than 150m, see „Cable Distances‟ page 13. In many
cases the video controllers will be in the same location as the door controller(s), but they
may be distributed as required to reduce wiring distances. When placed in different
locations, each location must have its own local power supplies.
Gate Controller
The gate switch controller BSSW is wired between the block door controllers and the video
controllers, so would normally be wall mounted next to a door controller.
For further details see the “bellissimo and Bellcall Manual Gate and Block (PD-120)”.
Separately Powered Apartment Stations
The limitation of up to 4 apartment stations ringing but only one displaying, as indicated in
the power supply and cable distance tables on page 13, can be overcome by the use of
supplementary power from a 340C.
Power Supply Requirements
The system is powered by 12V power supplies only: -
Model PS4 12V, 4A.
Model 840 12V, 4A battery backup supply.
Model 340C 12V, 1.5A optional for extensions.
Note 1. The 28V referred to on the apartment station, video controller and wiring diagrams
is internally generated in the controller. DO NOT use any power supply other than 12V or
damage may occur.
Note 2. The PS4 power supply has been specifically designed to operate with the high-
surge requirements of the system. Bell System is unable to guarantee functionality or
provide support for systems which use third party power supplies.

BF Apartment Station Digital Entry System
PD–166 Issue 1 Installation and Operating Manual Page 11 of 48
Exact power supply requirements depend upon many factors. The number of power
supplies included within a standard „kit‟ or quotation assumes that all controllers are
installed in one location and that there are no extensions.
The following table gives examples of the minimum number of controllers and power
supplies for a given number of entrance doors and flats.
System
Control Equipment and Power Supplies
1 door 16 flats
1 x BFD-DIG door controller for digital panel

BF Apartment Station Digital Entry System
PD–166 Issue 1 Installation and Operating Manual Page 12 of 48
Cable Specification
All system wiring must be carried out using Cat5 signal cable and where necessary 1mm²
(or greater) power cable as tabulated below. Cat5 cable has a known performance for the
transmission of video signals, whilst telephone or alarm cables are not suitable.
Bell System will be unable to offer any warranty or support for systems installed
using incorrect cables.
Cat5 Cable Specification
Cat5 is our short reference for EIA standard UTP Category 5 Unshielded Twisted Pair data
cable. This is a standard solid core twisted pair cable having 4 pairs (8-cores) and no
shield. The cores are in pairs where Blue and „Blue with a White stripe‟ are twisted
together as the first pair. The other three pairs are similar with main colours Orange,
Green and Brown.
Also available and acceptable are:
UTP Category 5e (Cat5e)
UTP Category 6 (CAT6)
UTP Category 6e (CAT6e)
The exact cable can be chosen from the above on cost and availability grounds.
STP (Shielded Twisted Pair) cables are not recommended.
UTP “patch cables” are not recommended.
NOTE: Cat5 cable is easily identifiable as the specification is printed on the sheath

Installation & Commissioning
Checklist
The following checklist is a summary of what is required. Refer to the relevant pages for
further details.
●Review the section headed „Safety Information‟ on page 47.
●Ensure that „Design Considerations‟ on page 9 have been understood.
●Confirm that Cat5 cable has been specified.
●Install the system according to instructions in this section.
●Check/set the door controller settings.
●Check/set the video controller jumper and switch settings.
●Check/set each apartment station dip-switch settings.
Wiring
Refer to the diagrams from page 33 onwards as appropriate for the equipment you have.
All wiring is carried out using a mixture of Cat5 for the signal wiring and 1mm² (or greater)
cores for the power wiring; refer to Page 12 for further details. It is strongly recommended
that a consistent colour code be used throughout such as that indicated on the connection
diagram. Certain signals must be interconnected using a twisted pair from the Cat5 cable.
These are clearly marked on the connection diagram and should be strictly observed.
Entrance Panel
The panel should be mounted at an optimum height of 1.6 m, measured between the
ground and the centre of the camera window. With flush mounting panels it is advisable to
apply mastic to the top and side edges of the panel to prevent water
ingress behind the panel, but not to the bottom edge. On construction
sites the panel must be protected from corrosive substances such as
„brick acid‟. The panel should be cleaned only with a damp cloth
containing dilute detergent.

BF Apartment Station Digital Entry System
PD–166 Issue 1 Installation and Operating Manual Page 15 of 48
Apartment Station
The apartment station is designed to be surface or flush wall mounted onto plasterboard or
other masonry at an optimum screen height of 1.6m. DDA considerations may reduce this
height to 1.4m. Dimensions are shown in the diagrams below.
Surface Mounting
Flush Mounting
Mounting requires three No 8 screws (not
supplied) and wall plugs may also be
needed for a secure fixing.
Flush fixing requires a hole in the
plasterboard reinforced with batons to give a
solid fixing for the four or six No 8 screws.
The reinforcing batons are longer than the
cut-out, so they may need to be split to allow
insertion.
The apartment station unit is removed from the wall mounting box by pushing in the two
circular buttons at the bottom and pulling apart, once open far enough the two hanging
clips will release/lift off.
Replace the apartment station unit by hanging it on to the two hooks at the top of the wall
mounting box and then push the bottom of the unit onto the two sprung clips.
Top, bottom and rear cable entry alternatives are available in the wall mounting box.
The Video terminator and dip-switch options are available from the back of the removable
unit.
The video terminator jumper is next to the removable 10 way connector block. Dip-switch
settings are summarised on the adjacent label (see also Page 25).
Doorbell
The apartment station has a doorbell function which is activated by the closure of a
normally open contact. This would typically be from a non-illuminated door push.

PD–166 Issue 1 Installation and Operating Manual Page 16 of 48
BSA Audio Phone
The BSA audio phone can be used as a lower cost alternative to an
extension apartment station. It is styled like the bellissimo
videophone. The phone is manufactured in high-impact ABS plastic
that imparts high durability and compliments most wall furnishings. It
incorporates both mute and lock illuminated buttons and it has an
Electronic Ringing Tone with an internal rotary pre-set volume control.
Remove the top cover of the BSA phone, which is secured by clips at
both sides, by using both hands and placing fingers under the edges
and using thumb pressure to release the clips.
The BSA audio phone should be fixed with two No 8 screws (not
supplied).
Videophone (Alternative to Apartment Station)
The BS Videophone is designed to be wall mounted onto
plasterboard or other masonry at an optimum height of 1.6m. DDA
requirements may require this to be lower.
Remove the top cover of the Videophone, which is secured by clips at
both sides, by using both hands and placing fingers under the edges
and using thumb pressure to release the clips.
If top or bottom cable entries are required, carefully remove the
appropriate cut-out with side snips taking care not to damage any
internal components.
The Videophone should be fixed with three No 8 screws (not
supplied).
The Videophone is hung on the top two screws, allowing the cable (if present) to feed
through and then the third screw is inserted at the bottom. Tighten all three screws.
Before replacing the Front Cover remove the protective film from the display lens and also
check that the dip-switch settings are correct or change as necessary (see Page 26).

BF Apartment Station Digital Entry System
PD–166 Issue 1 Installation and Operating Manual Page 17 of 48
Electric Door Release
Both fail-secure and fail-safe lock releases (including magnetic locks) use the same
terminals. To set the lock type, refer to the „Door Controller Settings‟. When installing lock
releases please allow a little movement on the door, as operation will be impaired if fitted
too tight.
NB. Magnetic locks (maglocks) must be fitted with a suppressor at the lock terminals.
Some manufacturers fit an acceptable internal suppressor.
Fail Safe Exit: Notes
Fail safe exits require an exit button and this should be normally open so that the controller
can be used to give a timed exit. If the exit button has both normally open and normally
closed contacts, then the normally closed contact can be wired in series with the release
or maglock along with the break glass in case of equipment failure.
A not uncommon problem with maglocks, because they cannot be mechanically
overridden, is being locked out of the building due to lost codes, fobs or equipment failure.
So consider an alternate building entrance, or an externally accessible secure keyswitch,
or a reliable method of disabling the system during overnight secure lockup.
Fail Secure Exit: Notes
Commonly fail secure exit doors incorporate a thumb-turn, door handle or mini push bar
rather than use of an exit button. Fire officers usually require a minimum of door handle or
push bar to open a door on a fire exit route –not a thumb-turn.
Most fail secure locks are not continuously rated and if an electrical hold open system is
used for say busy times, then a continuously rated release must be used.
Powered bolt, shoot-bolt or other more secure door locking systems may require the use
of separate power supplies or a suppressor to be fitted. Shoot-bolt systems for instance
tend to require at least 1.5A peak current and this will require the use of an isolation relay
and a separate power supply for the lock.
Exit Button Input
The exit button is used to unlock the door for the pre-set lock operating time. The input is
designed only for use with a normally open push button. „Exit +‟ is the input and „Exit -‟ is
internally connected to 0V.
The „Exit +‟ input can also be used for connection to other equipment to open the door as
shown in Diagram J on page 42
Door Open Switch
The door open switch is used to provide an indication at the apartment station that the
door has been left open. This switch can have closed contacts when the door is closed or
open contacts when the door is closed, the choice being made in Panel Programming.
The default of „contacts open when door closed‟ must be selected when this feature is not
required.
Time Clock Sharing
In a large system a single time clock can be shared between distributed equipment areas
by borrowing one of the „comm -‟ wires in the interconnecting Cat5 to use as the shared
“Time clock common”. See the detailed diagram on page 41.

BF Apartment Station Digital Entry System
PD–166 Issue 1 Installation and Operating Manual Page 18 of 48
Commissioning
The major components of the bellfree Digital system are fitted with high quality pluggable
screw terminal blocks. This enables all the connections to the system to be fully
completed, whilst easily isolating individual pieces of equipment during testing and
commissioning.
When powering up for the first time, it is highly recommended that only the most basic
system be connected. i.e. 1 BF apartment station, 1 door controller and panel, and 1 video
controller; the remaining equipment can be isolated by unplugging terminal blocks.
NB: Ensure the 1 door and video controller remain interconnected and that the „end of line‟
controller is terminated temporarily using the jumpers (see page 23).
Proceed to test the system by calling the apartment station from the door panel in the
usual way. Any problems can be resolved by rechecking wiring and connections, assisted
by the various suggestions and tests in the section “Troubleshooting”. Once the basic
system is fully functioning, continue to reconnect and test the remaining equipment item by
item until completed.

BFD-DIG Door Controller Settings
The BFD-DIG is programmed from the panel for all settings.
Security
It is strongly recommended that the Panel Security Code (PSEC) be changed from its
factory setting to prevent unauthorised access. Record the new number carefully as it
cannot be easily changed if lost. It is also recommended that the Phone Programming
Code (PPRG), Coded Access Code (ACOD) and Trades Access Code (TCOD) are all
changed from default even if not used.
To access panel programming without the code requires physical access to the controller
PCB, borrow a jumper from say video gain (remember the setting) and place it on the 5 pin
programming header between pins 1 & 2. Now pressing the test button will enter panel
programming for 30S when the panel security code can be read or set. When the
programming is finished replace the jumper back to its original location.
Panel Programming
To use Panel Programming Mode: -
First type the Panel Security Code (initially [3434]) followed by the call button.
The display will show the first programmable parameter (ACOD), and then alternating
at 1 second intervals will be the value and the parameter name.
Press the door button to step down through the programmable parameters.
Press the reception button to step up through the programmable parameters.
The list rolls over bottom to top and vice versa.
To change a numeric parameter simply type a new 1-4 digit value and then press call.
To change other values simply press call to choose the next value.
To exit Panel Program Mode press cancel.
If no button is pressed for 30 seconds then programming mode will auto-cancel.

ACOD –Primary Access Code
Main code to open the door. Applies whenever the display indicates [Code]. The Trades
mode (TRAD) needs to be set to „Code‟ or „Trade‟ as per the table below.
The code must be 4 digits and no letters, leading 0 is OK (e.g. [0246]).
TCOD –Secondary Access Code or Tradesmen’s Code
Secondary „tradesmen‟s‟ code to open the door. Valid only when the display indicates
[Code] and the time clock selects the Trade option as per the table below.
The code must be 4 digits and no letters, leading 0 is OK (e.g. [0137]).
LTIM –Lock Release Operating Time
Door unlocked duration. Range 1 to 99 seconds. Only the last 2 displayed digits are
used. A value of 0 will default to 1 second and a value containing alpha characters will
default to 3 seconds.
LOCK –Lock Type
[Secr] = Fail secure lock: - Requires alternate mechanical means, key or thumb-turn to
open on power failure.
[Safe] = Fail safe lock: - Lock opens on power failure.
CAM2 –Second Camera Present?
