Introduction
The BSX2 Door Entry Telephone System is designed for low rise blocks of flats in both the
public and private housing sectors. It provides the means for visitors to call an individual
resident within the building and to establish two-way speech communication (full duplex)
with them. The resident is allowed full control over the callers’ access to the building
entrance by means of an electric lock or lock release.
The BSX2 control Unit provides Full Isolation between individual dwellings so that any
damage sustained to an individual telephone or its associated cable will not affect the
operation of the rest of the system. The isolation also ensures that conversations are
totally private.
The BSX2 is available in four models with a capacity of up to 16 phones and 2 entrances.
For larger systems please refer to the digibell digital door entry system.

Basic System Operation
Making a Call
The Entrance panel has a push button for each flat in the building, engraved with the
associated flat number. A caller pushes the required button and the phone will start to ring
in the flat; this ringing tone will also be heard at the panel. The ringing will continue for 30
Seconds* or until the phone handset is picked up.
Once the handset is picked up the resident can talk to the caller for up to 60S*. During this
time the resident can press the lock button to release the door. An electric lock release
will operate for a fixed duration of 3 Seconds* and speech will continue until the lock
release has ceased operating. Alternatively replacing the handset on hook will finish the
call.
Audible indication at the panel is provided both when the phone is ringing and when the
door release is active. The door release tone has adjustable volume, while the ringing
tone comes from the phone and is fixed.
Privacy
To ensure complete privacy of speech and freedom from interference from other residents,
the audio and lock functions of the phones are disabled until the phone has been called.
Ringer Mute
Some models of phone have additional features such as Ringer Mute which can be
activated during periods when the sound of the phone ringing would be a nuisance (e.g.
baby sleeping, youths pressing buttons). See specific Phone models for more details.
Door Monitoring
Door Status Indication (Door Monitoring) is available on some models; when the entrance
door is left open, an LED indicator illuminates on the phone. This function requires a door
monitor switch to be installed at the door or in the lock release.
Trades (Optional)
If independent access to the building is required for tradesmen (e.g. Postman) then an
optional Trades button can be fitted to the panel. When the Trades button is pressed the
lock release will activate for 3 Seconds*. All the BSX systems have a Time Clock (with
auto BST and battery backup) which can be used to restrict the operating hours of the
Trades facility.
Second Entrance
On a system with two entrances the caller will be unable to ring any of the flats whilst the
other entrance is already in use. The system will indicate busy by sounding an intermittent
tone for 3 Seconds.
Egress
An optional Egress button can be fitted to the inside of the door to enable resident to freely
exit the building. A momentary press of the button will operate the electric lock release for
3 Seconds*.
*Lock and Ring and Speech times are programmable at installation –see Page 14

Entrance Panel
All Entrance panels are Vandal Resistant and made from 2.5mm marine grade (316)
stainless steel. Each panel is fitted with a high quality Speech Unit (model 61) and low
profile vandal resistant buttons. Panels are available up to 1 to16 buttons plus trades and
include custom engraving details. They are supplied with ‘tamper-proof’ security screws.
The standard VRP series are available both Flush and Surface mounted.
The LCP series panels have a flush mounted design and offer additional Vandal Resistant
features over the VRP series; the panel’s outer bezel is welded to a stainless steel back-
box whilst the inner removable panel has been ‘Laser Cut’ to ensure a minimal gap which
prevents the insertion of tools.
Control Equipment
All the control equipment for each system is supplied in a wall-mountable, lockable steel
cabinet. It includes all necessary control PCBs, a Power Supply with battery backup
capability and a Time-clock to control Tradesmen’s access. The cabinet should be
installed in a protected indoor environment.
Phones
Model 801 Phone
The 801 and 801S are the standard models. Ring volume is selectable to Low or High with
an internal jumper. The 801S ringer may also be muted in the event of nuisance calls;

BSX Isolated Audio Entry System
PD-142 Issue 1 Installation and Operating Manual Page 8 of 32
when the slide switch is in the mute position the ringer will not sound and the resident will
be unaware of calls until the switch is returned to the normal position.
Model BS LX Phone
The BS LX phone has both Door Status Indication and a sophisticated Ringer Mute facility.
Residents may mute the ringing of the BS LX by pushing the mute button on the phone; a
red LED illuminates as a reminder. Pushing the same button again will cancel the mute
function. Phones can be individually configured to automatically cancel the mute after a
pre-set time (2 min to 10 hrs.). While muted the phone will not audibly ring but the mute
LED will flash to indicate a call. Ring volume can be pre-set with an internal jumper (3
levels).
Door Status Indication is provided by the Lock button which will illuminate green whenever
the door is left open (a door monitor switch must be fitted).
Phone Options
All models of phone can be supplied with an inductive loop (IDL) to operate a hearing aid
with a ‘T’ switch.
Extension phones etc.
The BSX allows up to two phones to be connected to each output. An RT27 extension
sounder counts as one phone.
Extension sounders or strobes etc. that use their own power supplies, such as the SG1
multi-tone extension sounder or the FB31 strobe may be connected in addition to two
phones.
Electric Lock Releases
The BSX system supports either Fail-Secure or Fail-Safe lock releases or electric locks of
up to 1A rating at 12V DC.
Powered bolt, shoot-bolt or other more secure door locking systems may require the use
of separate power supplies. 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.
Fail-Safe Lock releases
Fail-Safe Lock Releases which include Magnetic Locks require power to lock the door and
will therefore fail open in the event of a power cut. An exit (egress) button should always
be fitted on the inside of the door; this should be a ‘normally open’ type.
Another issue to consider with magnetic locks (which cannot be mechanically overridden),
is the possibility of being locked out of the building, due to lost codes, fobs or equipment
failure. It is advisable to consider an alternate building entrance, or an externally
accessible, secure keyswitch, or other reliable method of overriding the system.
Fail Secure Lock Releases
Fail Secure Lock Releases require power to release the door lock and will therefore
remain locked in the event of a power failure. Fire regulations usually stipulate that the exit
door should incorporate a door-handle or push-bar and not an exit button or thumb-turn.
Most fail secure locks are not continuously rated however if an electrical ‘hold-open’
system is used (e.g. for busy periods) then a continuously rated release must be selected.

BSX Isolated Audio Entry System
PD-142 Issue 1 Installation and Operating Manual Page 9 of 32
Exit (Egress) Button
An exit button is used to unlock the door for the pre-set lock operating time. The input on
the controller is designed only for use with a normally open push button.
DDA Panels
The BSX system can meet the requirements of the Disability Discrimination Act (DDA).
Several options are available if required.
In the flat the availability of extension sounder and strobe accessories is the main
provision. Connection to other more specialist third party devices is also possible because
the ring signal is presented as an intermittent 12V output. Bell System will provide
technical information as required to those third parties, though this manual should be
sufficient.
At the door panel reassurance tones are standard, however DDA panels with visual
indication of Ringing, Speaking and Lock release via three LED’s are available on request.
Either high visibility halo buttons or illuminated tactile buttons are available for the call
buttons. The tactile buttons have raised illuminated numerals for the flat number; however
there is a limited range of numbers available. (Contact sales for further information).
Cable Requirements
Use 0.5mm solid-core twisted-pair phone cable (BT specification CW1308, Cat5 or
equivalent) for all phone and door panel connections; this is essential for correct operation
of the system and for compliance with European EMC Directive 89/336/EEC. Avoid
running any cables alongside mains or other data transmission wiring.

N.B. No extra equipment should be powered without first consulting the technical department.
Battery Backup
Space is provided in the cabinet to fit a standard 7AH battery to the power supply (both
Cab3 and Cab5 models) to provide battery backup in case of mains supply failure.
Backup time depends largely upon the idle power usage of the system which can vary
widely according to the following factors: - lock type, the number and type of phones, door
status indicator (on or off), the number of door panels and any additional equipment which
may be fitted.
The longest backup times are achievable with fail secure lock releases as these only take
current while unlocking the door; backup times exceeding 8 hours for a single door and 6
hours for a two door system are possible for moderate usage, reducing if system usage is
particularly high.
The use of fail safe lock releases will require individual calculation for back up time. For
instance, a 2 door system with 1A maglocks should not be expected to last much longer
than 2 hours.
Cab3 and Cab5 supplies do not support the use of batteries larger than 7AH.

Installation
Important:
●Review the section headed ‘Safety Information’ on Page 31.
●Ensure that ‘Design Considerations’ on Page 7 have been understood.
●Refer to the wiring diagrams from Page 27 onwards.
General
The major components of the 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.
Fitting the Control Unit
All of the equipment within the control unit box is mounted on a removable plate. It is
important that while the box is being drilled for cable-entry conduits and being secured to
the wall that the equipment is removed to prevent metal swarf from falling onto PCBs.
The mains connection can now be wired as per the section entitled ‘Safety
Information’ on Page 31 (Inside back page). Pay particular attention to earth
connections.
Installing the Battery
The battery (if required) should be installed only after all tests on the system have been
completed and any faults have been cleared. Take care not to inadvertently short out the
battery terminals as the available current (200A) may burn or overheat cables and other
metal objects. Once installed the battery is safe and fuse-protected. The battery sits on
the base of the control cabinet and is connected to the free spade connections already
provided. Ensure the correct polarity is observed; the red wire with the red spade terminal
goes to the battery positive terminal (also red).
Ensuring that the battery is fully charged may save test time.
Entrance
The panel should be mounted at an optimum height of 1.6 m, measured between the
ground and the top of the panel and is to be located on the wall adjacent to the main
entrance of the dwellings. 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.
All connections to the entrance panel and doors are provided by the control PCB marked
'BSX2'; dual entrance models contain two controller PCBs, each of which is connected to
one entrance as shown in diagram 1 or diagram 4.
Up to 16 push-buttons are wired to the control PCB as shown on Diagram 2. The buttons
are wired with 1 common for each group of 8 buttons giving a maximum requirement of 10
cores.
If the panel has a Trades button fitted it is wired as a separate pair of connections to the
terminals marked 'Trade'.

BSX Isolated Audio Entry System
PD-142 Issue 1 Installation and Operating Manual Page 12 of 32
Engaged lamp output
The engaged lamp output is on when the other door is busy (ringing or talking to a flat).
The output can be used drive a busy indicator.
Electric Door Release
When installing lock releases please allow a little movement on the door, as operation will
be impaired if fitted too tight.
The Control PCB provides a single pair of outputs for electric lock releases or maglocks. A
switch on the control PCB selects fail safe or fail secure, refer to the “Door Controller
Settings’.
'FAIL-SECURE' lock releases require power to release the door and therefore will secure
the door in the event of power failure.
'FAIL SAFE' lock releases and maglocks both require continuous power to lock the door
and thus will release the door if power fails.
Both outputs are specified at 12v DC with a maximum current consumption of 1A. For
electric lock releases of other types or specifications please contact the manufacturer for
information on interface adaptors.
N.B. Magnetic locks (maglocks) must be fitted with a suppressor at the lock terminals.
Some manufacturers fit an internal suppressor.
Trades Button
The Trades button is used in conjunction with the time clock to allow the door to be
opened directly during certain hours. The Trades button is internally wired via the time
clock to the Exit+ input. See “Exit Button” for further details.
Connections to the Phones
The phone connections are provided on the controller PCB. The connections are dual
numbered, that is Phone 1 (9), Phone 2 (10) etc. The left hand PCB is always 1-8 and the
right hand PCB if present is 9-16
There are 5 connections to each 801 phone and 7 connections to each BS-LX phone. A
separate cable must be used for each phone.
Connections to each phone are protected with relays and fuses and have a diagnostic
LED indication.
Door Monitoring Phone
For door monitoring the model BS-LX phone should be used. These phones are to be
connected with 7 wires. The controller has terminals marked 'DOOR +/-’ and this can be
wired to either normally open or normally closed door contacts. There is a switch setting
to select which type of contact is used.
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 BSX2 Controller Settings Page 14. The
default of ‘contacts closed when door is open’must be selected when this feature is not
required.

BSX Isolated Audio Entry System
PD-142 Issue 1 Installation and Operating Manual Page 13 of 32
Exit Button
The exit button input is for a normally open contact button. When pressed the Lock output
will activate and the tone will sound for the Lock Time as set on the switches, see BSX2
Controller Settings on Page 14. If the exit input is triggered for longer than the lock time
then the lock output will continue to operate until the input is removed. The tone will
however stop after the lock time.
‘Exit +’ is the input and ‘Exit –’ is internally connected to 0V.
The ‘Exit +’ input can also be used to allow other equipment to release the door.
Examples are shown on Pages 29 and 30.
If the exit button has a normally closed contact, then this can be wired in series with the
release or maglock and break glass. This will allow the door to be opened manually, even
if the equipment has failed, without having to break the glass.
Tone Output
Tone output is provided direct to the speech unit. The 801 and BS-LX phones generate
their own ringing tone which is not adjustable.
Busy tone and Lock operation tone is generated in the controller and is adjustable using a
volume control on the controller PCB (Page 27).

Testing & Commissioning
Safety
Before switching on the mains spur, ensure that the connection is correctly made
and that the cabinet is correctly earthed as per the section entitled ‘Safety
Information’ on Page 31 (Inside back page).
Leave the battery disconnected for now. Apply mains power to the control unit and turn on
at the power supply switch.
Basic Functional test
These tests require two people and assume the system is idle, watch out for buttons being
pressed at the other door panel if it is a two door system. When a push-button on the
entrance panel is pressed the associated Phone output LED, on the BSX2 PCB, will
activate and a call cycle will commence with ring voltage being sent to the phone.
Pressing the test button on the active door PCB will cancel the call, otherwise it will
continue to ring for the set time of 30 Seconds or 15 Seconds.
N.B. Pressing the test button when the system is idle will activate the door lock and tone
for 3 Seconds.
So for each phone on the system:-
1. Call the phone being tested by pushing the appropriate button on the entrance
panel; it should sound loud and clear.
2. While the phone is ringing Mute can be tested.
For an 801S slide the switch and the ringing stops, put it back.
For a BS-LX press the button, it will flash to indicate ringing and the ringing should
stop, press again to restart the ringing.
3. Pick up the handset and talk to the person at the panel. Speech should be clear in
both directions. On a BS-LX the Lock button on the phone should now be flashing.
4. Now press the lock button. The lock release should operate for 3 Seconds (or the
time set on the switches) and then immediately disconnect the call (LED on relay
board goes out).
Other panel functions such as DDA indicators can be checked while testing the phone, to
prove that they indicated at the right moments.
If the there is a second door panel it is only necessary to test it with one phone and carry
out the speech and lock test while observing the DDA indicators, if present. To test the
busy indicator, if present, make a call at one panel and then try and make a call at the
second panel while the first call is in progress. The busy indicator should be on during the
other call and pressing a button should cause a busy tone to be sounded –assuming that
the tone volume control is not turned fully down.

Adjusting the 61 Speech Unit
The Model 61 Speech Unit has 2 volume controls:-
A (Speaker symbol): controls the speech level from phone to panel.
B (Microphone symbol): controls the speech level from panel to phone.
Initially set both controls to mid-position and adjust each in turn for optimum speech clarity.
It should be noted that if either or both controls are turned too high there will be a howling
sound caused by acoustic feedback. This problem may also be induced by allowing a
space between the speech unit and the inside surface of the panel (i.e. grill).
Battery Tests
Now connect the battery.
Then test the system again with any phone, firstly with the mains on and secondly with it
off. If the system fails to operate satisfactorily when the mains is switched off, then check
the battery fuse inside the Cab3/5 and also the battery voltage (should be >10.4V, 13.8V
+/-0.25V fully charged). If the battery voltage is low then allow it to charge for at least 30
minute and test again.
Cab3 or Cab5 power supplies can shut down their output for 15 minutes if the battery is
very discharged.
For further power supply diagnostic information see the Troubleshooting section Page 20.

Troubleshooting
Common Faults
A very high percentage of calls to our technical support number, regarding new
installations, are resolved to faulty wiring. The reasons for these are various: -
Broken cores, especially short links, sometimes broken inside the insulation!
Connectors clamped onto the insulation instead of copper.
Wire in the wrong side of a rising clamp connection, the clamps need to be unscrewed
far enough to stop the wire going “underneath”.
Shorts or opens due to cables having been stapled or nailed through.
A common fault is wiring a connector left to right instead of right to left, or one or more
twisted pairs the wrong way round.
Tip. The heads of screws on connectors are not a reliable means of making a connection
with a meter, try pushing the probe into the wire entry point.
