Introduction
Description
A bellissimo video door entry system consists of a door panel, positioned at the entrance
of a building, video telephones (videophone), 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 and several push buttons –one of which must be depressed by a visitor to initiate
a call. The videophone, which rings in response, allows a two-way conversation via a
handset whilst the caller can be observed through the integral display. The operator can
selectively allow visitors access to the building by pressing a button on the videophone
and so electrically releasing the door.
The bellissimo 2-72-way Video Door Entry System is suitable for any building requiring
multiple push buttons at the entrance, such as blocks of flats or multiple offices. For
buildings requiring a single push button at the entrance, such as houses, individual flats
and offices, please refer to the “bellissimo 1-way Video Entry System” manual. For a
digital panel with display, refer to the bellissimo Digital System.
The bellissimo “2-72-way” system is supplied with a dedicated door controller, for each
entrance, and a video controller for every four videophones. The basic system supports 1
videophone per call button, and up to 3 extension videophones (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
Call sequence
When the call button is pressed at the entrance panel it causes the videophone to ring and
the amber view lamp to flash. The videophone will continue to ring for up to 30 seconds
or until the resident responds by picking up the handset. At this time the resident can
freely converse with the visitor whose image is now displayed on the videophone; at the
same time the green lock lamp will flash to highlight the lock button.
The call may be terminated by replacing the handset or more usually by pressing the lock
button 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.
Videophone Controls
The diagram in the introduction shows the standard colour monitor and its controls. The
default setting is ringer volume midway and contrast maximum (slide finger to top).
Auto Display
When ‘Auto Display’ mode is selected the picture will come on while the videophone 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 videophone per flat
should be set in this mode (see ‘Extension Videophones’ below).
Call Mute
The resident can mute the ringing sound in the videophone when they do not wish to be
disturbed. Call mute is activated by pressing the mute button on the videophone, which
then illuminates in red as a reminder. The handset must be on the hook for this to work.
Pressing the mute button a second time will disengage the mute function. During
installation it is possible to set a time limit for the mute function in various values from 2
minutes up to 10 hours, indefinitely or disabled. When this time period has elapsed the
mute function will automatically disengage. (See ‘mute timer’, page 22).
Mute only stops the audible ring, but the amber view light will still flash and all other
functions work normally. Mute will continue for the preset time even if a call is answered.
Silent viewing
When the videophone is ringing the resident can press the view button to answer the call
instead of lifting up the handset; this will stop the videophone ringing and enable them to
view the visitor for up to 60 seconds or until the lock button is pressed to release the door.
Silent viewing can be ‘normalised’ at any time by picking up the handset and conversing
with the visitor as described above.
Door Status Indication
The green lock lamp on the videophone 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 answered by one videophone no other videophones may join in,
view or listen to the call. If another videophones handset is picked up, or the view button
is pressed, the videophone will not activate.

bell issimo 2-72 Way Video Entry System
PD-098 Issue 4B Installation and Operating Manual Page 7 of 44
User Activation (CCTV Mode)
User activation is a feature of the bellissimo 1 way system and is not available on multi-
way 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.
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. Pressing the view button 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 Options Diagram on page 36 for details.
Extension Videophones
Additional videophones may be added to each ‘flat’. The number of extensions is limited
only by power supply considerations. All videophones for that ‘flat’ will ring when called
however typically only the master unit will display a picture while ringing. Once the master
or extension videophone 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 set between 3 and 20 seconds. (See ‘Lock
Operating time’ and ‘Lock Type’ on page 18.
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
Use of a time clock in conjunction with a trades button will allow free access during the
programmed time(s).
DDA Functionality
The bellissimo 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, reassurance tones and LED indicators for “Speak Now” and “Door Open”.
Contact your sales representative for further details.
Reassurance tone setting is on page 19.

PD-098 Issue 4B Installation and Operating Manual Page 8 of 44
Multiple Entrances
The bellissimo 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)”.
Door Bell
The BS Videophone has an input which can be used with a doorbell button (or other volt
free contact) to ring the phone. This feature is intended to replace a separate doorbell.
The ring is 2 seconds and all three indicators flash together.
Slave Output
The BS Videophone has a slave output which can operate an external ringer or other
device such as a flashing beacon.
This comprises of a volt-free contact which closes when the videophone is audibly ringing.
The contact does not close when the videophone is muted.

PD-098 Issue 4B Installation and Operating Manual Page 10 of 44
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.
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
videophone 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 Videophones
The limitation of up to 4 videophones 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 videophone, 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.

bell issimo 2-72 Way Video Entry System
PD-098 Issue 4B Installation and Operating Manual Page 11 of 44
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.

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
Patch cable is used for the desk phone to wall connection as this requires a flexible cable.
The reason for not using it for general wiring is that attenuation is higher and video
distances would be reduced by at least ½, it also costs 2 to 3 times as much as standard
Cat5.
Spurs. A daisy chain run with one or more spurs of up to 3 metres is allowed. For
example a desk phone connection.

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 42.
●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 jumper and switch settings.
●Check/set the video controller jumper and switch settings.
●Check/set each videophone dipswitch settings.
Wiring
Refer to the diagrams from page 28 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.
Videophone
The videophone is designed to be wall mounted onto plasterboard
or other masonry at an optimum height of 1.6m. It should be fixed
with three No 8 pan head screws (not supplied). Use the
dimensions shown on the adjacent diagram. If the cable is to be
fed from the wall cavity then make a hole for this at the same time,
the surface cable exit is to the left of the cut-out. The top two
screws are hidden fixings, so screw in but do not fully tighten. Test
hang the videophone and adjust the screws as required.
Now remove the top cover of the videophone, which is secured by
a clip at the bottom. Hang the videophone on the two screws
already fitted allowing the cable (if present) to feed through and the
third screw to be inserted at the bottom. Tighten the third screw.
If the silicone rubber buttons fall out, clip them back into the PCB.
Before replacing the Front Cover remove the protective film from
the display lens and also check that the DipSwitch settings are
correct or change as necessary (see Page 22).

PD-098 Issue 4B Installation and Operating Manual Page 15 of 44
Audio Phones
The BSA audio phone can be used as a lower cost alternative to an extension videophone.
It is styled like the bellissimo videophone. The phone is manufactured in white and grey
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 rotary preset volume.
BSA Phone
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.

bell issimo 2-72 Way Video Entry System
PD-098 Issue 4B Installation and Operating Manual Page 16 of 44
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 preset 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 K –bellissimo Combined System Connections.
Door Open Switch
The door open switch is used to provide an indication at the phone 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 36.
Commissioning
The major components of the bellissimo Video 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 BS videophone, 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 20).
Proceed to test the system by calling the videophone 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.

BSD8/72 Door Controller Jumper Settings
Camera Terminator
There is a separate jumper for both video Camera inputs. This has three settings, 75R for
terminating coaxial cable, 100R for terminating twisted pair Cat5 cable and None for use
when passing the cable on to another device or controller.
Video Gain Control
The “Video Gain” jumper on door controllers should always be set to “0” unless directed by
‘Bell System Technical Support’. This jumper is only required on some systems with very
long camera to videophone cable runs well in excess of 150m. Inappropriate use of this
jumper with short runs will cause picture problems.
Reassurance tones
DDA reassurance tones are activated by placing a jumper between pins 1 & 2 of the
“Prog” 5 pin header on the BSD8/BSD72 controller PCB (see diagram on page 30), the
jumper is stored between pins 4 & 5. Once activated the speaker in the door panel will
ring with the videophone and buzz when the lock is opened from the videophone.
