Introduction
Description
The BSSW gate controller is used in two level “gate and block” applications to provide
block isolation where a main gate is used to access 2 or more blocks. Each block
operates independently from local entrances when not being called from the gate.
Up to 4 gates may be independently wired to each BSSW.
Each gate may consist of multiple panels and associated controllers.
Main Features
●4 independent entrance gates per controller.
●Simple address translation to allow one button per flat panels at the block.
Design Considerations
Application
The BSSW has the main purpose of being a two level switcher and is primarily intended
for gate and block architecture.
However it can also be used to apply pure block isolation if required and may be
appropriate for multiple riser application.
One limitation is that there should only be three controllers of any type between the
camera and the videophone. Applications with four controllers are not qualified.
Address translation can be used to allow use of one button per input panels for local
“block” doors. These generate low valued and fixed addresses e.g. a BSD8 gives 1 to 8, a
BSD72 gives 1 to 72. For these SW2 and SW3 allow address translation from the HIGH
postal address down to the LOW local address by subtracting any number from 0 to 239.
typically local addressing starts at 1, so if the postal address for that phone is N, set the
total on the switches to N-1.
EXAMPLE. A scheme of small blocks has addresses “Orchard Close 1-84” and one block
is 70-75. SW2 & SW3 need to add up to 69, so set SW2 to 3 (8), SW3-1 ON and SW3-2
OFF (60), SW3-3 ON and SW3-4 OFF (1) which adds up: 8+60+1=69. Phone addresses
in the block are 1-6.
Limitations
Door left open status is local to a block, that is phones in an isolated block only indicate
“door open” from door controllers in that block.
When a block is in use (Busy) a call from the gate will “Fail” rather than indicate “Busy”.

Installation & Commissioning
Checklist
The following checklist is a summary of what is required. Refer to the relevant pages for
further details.
●Ensure that ‘Design Considerations’ on page 4 have been understood.
●Confirm that Cat5 cable has been specified.
●Install the system according to instructions in this section.
Wiring
Refer to the diagrams from page 10 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 the main system manuals for detailed information.
Gate Controller
The BSSW gate controller is wired between the block door controllers and the video
controllers, so would normally be wall mounted next to a door controller.
Wiring the BSSW between the local door controller(s) and the video controller(s) prevents
potential camera switching problems when a gate is calling.
Gate Entrance Controller
The gate entrance controller, which is of course a door controller, should be mounted as
such. The location will be site dependant in order to meet the 50m requirement.
The output Cat5 has to daisy chain from block to block in order to preserve the quality of
the video signal.
In the case of two or more gate entrances, the daisy chained Cat5 cable need not take the
same route, just the shortest.

Commissioning
The major components of the bellissimo 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.
It is highly recommended that the blocks are first tested with the BSSW controller
bypassed. Once the block is known to be working correctly, connect the BSSW controller
in order to test the gate connection.
Programming Phones Through a BSSW
Draft
When using BC801 or BSA phones in a bellcall system the phones need to be
programmed. Phones can be programmed from a local panel or from the gate panel.
Bell System recommend that phones are pre-programmed prior to installation onto the
wall, this can speed up the process and reduce the manpower requirement.
This programming can be done on site using a temporary set-up or prior to going to site
using a bench set-up.
Alternatively phones can be ordered pre-programmed for a small extra cost (use part
number BC801/P or BSA/P and provide a list of required numbering).
When programmed from the gate panel any address translation set at a BSSW is ignored
and the phone is programmed with the address entered at the panel.
Example 1. A gate and block system has a small block with six flats and a one button per
flat panel has been used locally, however the flats have postal addresses 70 through 75.
The local controller uses addresses 1 to 6 and so this is the address required for the
phones. The BSSW is set for an address translation of –69 so that 70 becomes 1 and so
on. The phones have already been installed and so they are to be programmed from the
gate. The standard programming method for the controller is used (see the correct
controller manual) and the first phone (70) is programmed as 1, and then tested as 70.
The phones would also be checked from the local panel.
WARNING. When the programming code is entered from the gate, all phones in the
system become active and await being picked up!!. To avoid any side effects it would be
feasible to temporarily disconnect all but one BSSW, otherwise BEWARE!!.

Setting Up the BSSW Gate Controller / Block Isolator
There are 4 inputs for sources common to multiple blocks which can be used as
termination or passthru. In a bellissimo video system the cable runs for passthru must be
daisy chained, but for bellcall audio they can be star or combination wired. The terminator
is for bellissimo video systems only.
The Input and output connections are again specific to bellissimo video use where the
video signal is switched to maintain termination. For bellcall audio use they are identical.
The input and output connections are connected into the isolated block (group of phones).
Door panels connected into the isolated block can only call phones within the block,
whereas door panels connected to the gate inputs can call into the block whenever there is
no ongoing call activity.
SW2 & SW3 Setting – Block Address Offset
For systems where all the panels are digital, then SW2 will remain in the 0 or OFF
position. All panels use the postal address so there is normally no need fro translation.
However blocks tend to be small and may use one button per input panels which generate
low valued and fixed addresses (BSD8=1-8, BSD72=1-72). For these SW2 and SW3
allow address translation from the HIGH postal address down to the LOW local address by
subtracting any number from 0 to 239.
So for postal address N and local address 1 then set the total on the switches to N-1

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.
Quick Fault Reference
These tables provide a quick indication of the possible fault.
Call Problems
Local Block calls.  Data connection is directly wired from input to output
connector, so fault must be elsewhere or be a wiring fault
at the interconnections. Test by bypassing the BSSW.
Gate calls.  Eliminate other faults by debugging the local block first.
 Check the address translation if being used. Try
switching it off and calling using the actual phone
address. N.B. Ensure other blocks are temporarily
isolated from the gate to prevent multiple phones ringing.
 To check gate input, switch off address translation
(SW2=0) and move the input connector to the gate
connection. Make a block call.
Audio Problems
No audio from gate.  Broken wire or wiring fault on the audio pair from the gate.
Loud feedback at gate.  Open or short circuit on audio pair.
Audio fault from block.  Connection is direct from input to output connector, so
fault MUST be elsewhere or be a wiring fault.
Video Problems
No Video but calls are
otherwise OK.  Broken or shorted wiring.
Picture quality  Ensure that the terminators for the gate wiring are correct,
just the end of the cable run is terminated.

Diagram A – bellissimo Gate and Block Wiring
Site Overview
A “Site” consist of 1 or more “Gates” and 2 or
more blocks.
The Cat5 from each “Gate” is daisy chained
around the blocks to ensure that video quality
is maintained. Different “Gates” may take
different routes, but aiming for the shortest
runs.
Gate Detail
A “Gate” consists of 1 or more panels and
associated controllers. For instance the
panels may consist of a lorry panel and a car
panel at a vehicle gate plus a pedestrian
panel for a pedestrian gate. These can be
grouped as a single logical “Gate”.
The controllers have to be within 50m of the
panels in an appropriately protected housing.
Block Detail
A “Block” may either be a physical building
with 1 or more entrances or just a logical
collection of flats which need their wiring
isolated.
Equipment consists of 1 BSSW, 1 or more
BSC4’s and 0 or more door controllers.

Diagram B – bellcall Gate and Block Wiring
Site Overview
A site consist of 1 or more “Gates” and 2 or
more blocks.
The wiring is shown logically with the Cat5 or
telephone cable from each gate connecting to
each block. There can be T or even star
junctions.
Gate Detail
A “Gate” consists of 1 or more panels and
associated controllers.
The controllers may be local to the panels or
up to 50m away in a dry housing or the
nearest block.
Gates would normally use BSD-DIG and
BCP1/VR panels due to weather exposure at
the gate, where the BCP1 integrated panels
are not recommended.
Block Detail
Each “Block” may be either a physical building or just a logical collection of flats.
There will be a minimum of 1 or more phones and either a BSSW or 1 or more BSC4-
AD’s.
In addition there may be 0 or more BSC4-AD’s and 0 or more door controllers.
