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.
