BUS2 panels ‘BUS2 amplifier’
All BUS2 panels (City, Direct, Digital) have a BUS2 amplifier which manages all system functions (call, dual-direction
communication, door opening, programming, etc.).
There are two types of BUS2 amplifiers:
BUS2 AUDIO amplifier
The main characteristics of the BUS2 amplifiers are as follows:
* Camera incorporated in the video amplifier
The BUS2 video amplifiers have one single electronic unit with the remote camera and their adjustment
elements: pan&tilt, remote camera illumination LEDs.
* Mapping function
In panels with buttons, the mapping function enables advanced programming of call code button combinations
different to the standard assignation (see section ‘Advanced Programming. Mapping’.
* Voice synthesiser
Every amplifier is fitted with a voice synthesiser module, which transmits the message ‘ Door open, please
close after entering’ every time the lock-release command is activated from an apartment.
The language of this message can be configured: Default languages are French, English, Spanish and German,
depending on the position of the message selection switch, or can be cancelled if it is not placed at any of the
positions.
The synthesiser module can be replaced by other versions which include other languages (Valencian, Catalan,
Portuguese, Polish, Dutch, Russian, etc.). For more information, please consult the technical information code
94335b.
* Programming Lock-Release Times
The lock-release time can be programmed between 1 and 99 seconds (a keypad is required; an auxiliary keypad
can be used with city button panels).
* For installations of one or two accesses
In systems with two accesses, one of the panels must be defined as MAIN ACCESS (in diagrams shown with
‘1’), with the other defined as SECONDARY ACCESS (in diagrams shown with ‘2’), using a switch (JP2) located
in the panel amplifier.
System programming must always be carried out from the ACCESS 1 panel, that is, from the one in which this
switch has been left in place. See installation diagrams.
* Potential-free relay (C, NO, NC): continuous or alternating lock-release activation.
The BUS2 amplifier is fitted with a potential-free relay which enables continuous (12Vdc, 0.5A) or alternating
(12Vac, max 4A) lock-release connection.
* Without cabling errors
The BUS2 system has been designed to prevent cabling errors, given that the connection is carried out using 2
polarity-free wires.
* Restore default values
The BUS2 amplifier has a ‘Reset’ function which can be used to restore programmed default parameters (door
and hall lock-release time, access codes, mapping) (see section ‘BUS2 amplifiers, reset’)
