GENERAL INFORMATION

The "Simplebus2" system is characterised by simple cabling
with just 2 unpolarised wires in each stretch of the system.
It is therefore no longer necessary to have either a local power
supply or a centralised power supply by means of additional
conductors.
The entirely 2 wire-technology therefore offers the advantage
of no longer having to worry about the number of conductors to be
branched from the main riser and the type of external unit to be
installed. The conversion from internal telephone unit to internal
video-telephone unit is immediate.
Combined with the "Powercom" entrance panel, characterised
by absolute simplicity of installation thanks to the modularity
of its elements, the "Simplebus2" system becomes extremely
easy to cable, eliminating the possibility of errors and drastically
reducing installation times.
A vast range of accessories is also available to solve all system
requirements easily. The system can manage up to 240 users,
connecting a MAX of 3 branches with the same user code.
The standard system is fitted with the door-opening function, call to
porter switchboard/ auxiliary push-button and self-ignition. It is also
possible to have optional card s for special needs (e.g. additional
LEDs and push-buttons).
For the full description of the articles regarding the Simplebus2
system, please refer to Catalogue 66.

WARNINGS FOR THE USER

In the case of a fault or malfunction of any part of the system,
only contact the approved installer or qualified personnel.

GENERAL INSTALLATION INSTRUCTIONS

• Connect a maximum of 100 units for each riser.
• Connect a maximum of 3 units with each user code.
• The system can manage a maximum of 240 users.
• In door entry phone only systems, the maximum operating
distance between the door and the telephone furthest away is
400mt regardless of the type of cable used and the type of
system.

OPERATING NOTES

• When the visitor presses the call button the bell of the internal
unit is activated.
• There is a reassurance tone for the call having been made at the
external unit. If the call confirmation tone is not heard in systems
with several entrances, it means that another conversation is
taking place with another external unit installed on the same
riser. In the case where Art. 3346 - system engaged signalling
module - is installed, wait until the module turns off before
making the call again.
• At the internal unit, communication takes place by lifting the
handset.
• The button marked with the key symbol acts on the electric lock
of the external unit, activating it for about 2 sec.
• By replacing the handset of the internal unit, you have a few
seconds to replace the audio with the external unit.
• Telephones with same user code all ring at the same time
(regardless of whether they are main or secondary) on a call
from the external unit and on a local floor call.
