Bellcall Digital Door Entry System
PD-083 Issue 3A
Installation and Operating Manual
Page 5 of 46
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 bell
issimo
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.

necessary electronics for connection onto the Bellcall digital bus.

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.
