Introduction
Description
Bellcall is a digitally signalled phone system with keypad style flat number entry.
A Bellcall door entry system consists of a door panel, positioned at the entrance of a
building, door entry phones, placed inside of the building for the convenience of the
occupants, a power supply and controller which are usually located inside an electrical
cupboard. The door panel comprises of a two-way speech unit, an LED display and
sixteen push buttons – which are used by a visitor to initiate a call. The phone, which rings
in response, allows a two-way conversation via a handset. The operator can selectively
allow visitors access to the building by pressing a button on the phone and so electrically
releasing the door.
The Bellcall digital door entry system is suitable for any building requiring to address more
phones than considered practical for a conventional pushbutton panel.
The Bellcall digital system is supplied with a dedicated door controller, for each entrance
(the standard unit includes this in the panel assembly). The basic system supports 1
phone per address and a number of extension phones, consideration must be given to
cabling and power supply’s for the extra ringing current. Multiple entrances can be
supported with the addition of one panel (and one door controller if vandal resistant) for
each entrance.
Main Features
 12V d.c. operation
 BCP1 surface or BCP1F flush mounted panel with integrated controller.
 BCP1/xxx vandal resistant panel types with separate controller for security.

door left open indicator.
 BC801 digital version of the popular 801 phone.
 High quality full-duplex speech amplifier.
 Inherent privacy of speech.
 Coded access facility built in (single 4 digit code).
 Facility for exit button.
 Timed lock release, fail safe or fail secure and magnetic locks (maglock).
 Reception (Porter) facility built in.
 Simple parallel wired system with a 6 wire bus.
 Simply add door controllers onto the bus for multiple entrances.
 Systems with over 1000 phones possible.
 Trades facility built in (requires external time clock).

The standard BCP1 integrated version needs no other control equipment, just the required
number of entrance panels, phones and a power supply. (Extra doors may need extra
power supplies). The system works on a 6-wire bus (6 common wires) with only the
requirement to take care of power supply distribution on larger systems (see table later in
this document). The use of standard Cat5 or CW1308 phone cable makes cable
installation extremely economic.
The vandal resistant version of the panel uses a separate controller which normally needs
to be positioned within 50m of the panel. This has added security as opening the panel
gives no access to door lock circuitry.
Clear and concise display messages are presented to the visitor. Simple commissioning
with user-friendly display messages.
The Bellcall system is very flexible and can be as simple as the system detailed above to
larger systems with BSC4-AD group isolators and possibly BSSW gate switchers. It is
also feasible that other bellissimo BSD8 or BSD72 controllers may be used in mixed
systems to provide small blocks with 1 button per flat panels. See ‘Design Considerations’
for more detail.
N.B. The term “Flat” is used generically to mean Flat, House or Office etc.
Phone Details
The BC801 phone is identical in style to our popular model 801 phone but contains the
necessary electronics for connection onto the Bellcall digital bus. The phone is
manufactured in white and grey high-impact ABS plastic that imparts high durability and
compliments most wall furnishings. It incorporates a ‘lock release’ push-button discreetly
positioned on the base, and under the handset, to prevent inadvertent use. It has an
Electronic Ringing Tone.
The BS-A phone is styled like our bellissimo videophone for audio only digital systems.
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. It has an Electronic Ringing Tone with rotary preset volume.

Basic System Operation
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 time will give C then
pressing <Z once will give B, or starting with pressing Z 5 times will give V and then
pressing >A twice will give X. To end the entering of a character is done by pressing a
number button or call.
The call button is used to call flats or end sequences, in effect OK.
The cancel button cancels the current entry leaving a blank display.
The reception or Porter (Suitcase) button calls a 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 callers address entered and the call button is pressed at the entrance panel it
causes the phone to ring and the red mute lamp to flash. The phone will continue to ring
for up to 30 seconds or until the resident responds by picking up the handset. 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 to allow the visitor access through the entrance.
Phone Controls

Call Mute – BS-A Only
The resident can mute the phones ringing sound when they do not wish to be disturbed.
Call mute is activated by pressing the mute button on the phone, which illuminates in red
as a reminder. 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 or indefinitely. When this time period has elapsed the mute
function will automatically disengage. (See ‘mute timer’, page 18).
The mute feature stops the audible ring, but the red mute light will still flash to indicate a
call and all other functions work normally. Ringer mute will continue for the preset time
even if a call is answered.
Door Status Indication – BS-A Only
The green lock lamp on the phone 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 phone(s) which is/are ringing
may answer the call. Once answered, if another phones handset is picked up, the phone
will not activate (including extensions of the active phone).
Extension Phones
Additional phones may be added to each ‘flat’. The number of extensions is limited only
by power supply and cabling considerations. All phones for that ‘flat’ will ring when called.
Once a phone is ‘picked-up’ the conversation will only be with that phone.
Lock Type and Operation
The door controller supports both fail-secure and fail-safe locks including magnetic locks of
up to 0.5A rating (1A BSD-DIG). The lock output is provided by a relay contact (transistor
on BSD-DIG) switching Lock -, which in the event of power failure does not drive.
On pressing the lock button the lock timer will start and the door will unlock. For Lock
Time settings see page 19.
Exit Button
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.
Trades Facility – Timed
Use of a time clock in conjunction with the door button allows free or coded access during
the programmed time. Without the time clock coded access can be used or disabled.
DDA Functionality
The vandal resistant version of Bellcall 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 phone ringing and door released.
Contact your sales representative for further details.
Multiple Entrances
The Bellcall 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.

Design Considerations
Equipment List
A Bellcall digital audio systems can vary in content significantly, but comprise of the
following items: -
 A number of phones, either the new BS-A phones or the older BC801
 None or more BSC4-AD Audio controllers as required to break up the wiring into 4
smaller segments each.
Then for each door:- Either
 BCP1(F) Integrated door panel and controller.
Or a door panel and controller.
 BCP1/LCP Vandal resistant panel LCP option.
 BCP1/VR(S) Vandal resistant panel standard VR option.
 BSD-DIG Door controller.
 61 speech unit.
And common items
 Power supply, see below for alternatives.
 203 Fail-secure lock release, alternate types available.
 DDA panels (Contact sales for further information).
Equipment Options
At the simplest all the door controllers and phones can be connected on a single bus, and
this works for smaller systems. However there is a data limitation of 128 items (phones or
controllers) on a single bus, and a total cable length limitation of about 1000metres.
BSC4-AD audio controller. This controller performs group isolation and allows both of the
above limits to be overcome. Each controller can split the phones into 4 groups which are
isolated from each other. Installation and maintenance are also improved in that if a fault
develops in a group of common wired phones, the fault is already isolated to just those few
phones.
Full Isolation. This is achieved by using the above BSC4-AD controllers with just one flat
per output. When doing this it becomes more efficient to use the BSC4-AD’s ability to use
unprogrammed or programmed phones with the BSC4-AD decoding the address.
BSSW Gate switcher block isolator. This controller is used wherever 2 or more blocks of
phones share a common door or gate and independent operation of the blocks is required.

Bellcall Digital Door Entry System
PD-083 Issue 3A Installation and Operating Manual Page 9 of 46
That is in a fully common wired system only 1 door can make a call at a time, in a block
isolated system there can be a call in every block simultaneously.
BSD8 and BSD72. These one button per flat controllers can be used to ring phones with
addresses of 1 to 8 and 1 to 72 respectively and would normally be used for a small block
in conjunction with a BSSW which can translate phone addresses. The bellissimo
manuals for these controllers would be used to determine switch settings. Application
would normally be as a result of contacting the technical department.
Mixed Audio Video Systems. A Bellcall system can be connected to a bellissimo video
system where there are shared entrances, the BSSW would be the recommended method.
All wiring carrying video must be installed to the requirements of the relevant bellissimo
installation manuals, however the Bellcall wiring may be added to any convenient point.
Do not connect the video signal into the Bellcall wiring.
Power Supply Requirements
The system is powered by 12V power supplies only: -
PS4 12V 4A Standard Supply
340C 12V 1.5A Standard Supply
840 12V 4A Battery backed supply
640 12V 1A Battery backed supply
Exact power supply requirements depend upon many factors. The number of power
supplies included for a system may assume that all boxed controllers are installed in one
location and that there are no extensions. More equipment may be required for distributed
installations.

Cable Specification.
DO NOT USE Alarm cable.
All system wiring must be carried out using either Cat5 signal or CW1308 telephone cable
and where necessary 1mm² (or greater) power cable as tabulated below. Cat5 cable is
strongly recommended as it has a better performance and may allow future upgrades with
less re-cabling.
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 0.5mm diameter 0.2mm² 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.
NOTE: Cat5 cable is easily identifiable as the specification is printed on the sheath.
UTP Patch cable is normally more expensive, but is otherwise suitable for audio and data
use.
CW1308 Cable Specification
CW1308 is the international standard for telephone cable which is available in sizes from 1
pair to in excess of 25 pair. The standard CW1308 has 0.5mm diameter 0.2mm² cores.
Different grades are available including a cheaper 0.4mm diameter 0.12mm² core and a
1.38mm diameter 1.5mm² core for long distance, though these are not normally available
through common outlets. All our calculations are based on the 0.5mm diameter cores
which are the same as Cat5 cores.
