Comelit simplehome - 1 Introduction; 1.1 SimpleHome System Architecture; 1.2 System Power Supply and Modules

1 - INTRODUCTION
Besides a short introduction to the philosophy behind SimpleHome by Comelit, this manual also provides a detailed description of the range of
home automation products currently available and the corresponding programming/con guration software.
1.1 - SIMPLEHOME: DISTRIBUTED INTELLIGENCE AND PROPRIETARY PROTOCOL
Creating a distributed intelligence home automation system guarantees the following:
- limited system costs, even for small installations such as single/two-family apartments, because - as with centralised logic systems - it is not
necessary to install a control unit;
- greater protection against potential system locking, due to the fact that if a module is locked (e.g. following a surge or  ooding), only the
services (lights or buttons) served by that module will cease responding to commands, meaning that the rest of the system can continue to
run as normal;
- use of normal cables (even electrical cord, where permitted by law), limiting costs and material management: SimpleHome actually uses three
normal electrical wires sized in accordance with the length of the bus and the number of devices on the section. It should be noted, however,
that shielding offers greater protection from disturbances caused by magnetic  elds.
The protocol used by SimpleHome was created by Comelit and is therefore not directly compatible with equipment made by other manufacturers;
in spite of this, however, it is possible to access module information (digital and analogue input status) and transmit commands to them (digital and
analogue outputs) using an interface (SerialBridge) that converts information and makes it available in accordance with universal ModBus protocol
(e.g. use with industrial operator panels or building supervision programs). Another interface of the same type (SerialBridge) can be connected to
the safety module, making it possible to monitor and control the alarm system using a third party terminal or program.
1.2 - SIMPLEHOME: MULTIFUNCTIONAL MODULES, DISTRIBUTED POWER SUPPLY
The Comelit SimpleHome home automation system does not require modules dedicated to speci c functions, such as
rolling shutters or scenarios, as each bus device is multifunctional and can be programmed to carry out any task.
Moreover, some of the SimpleHome modules offer the option of on-board power outputs with the same number of digital inputs
available, optimising system con guration and signi cantly reducing the total cost.
The system power supply is provided by 24 Vdc 2A DIN bar power supply units, which can be  tted in parallel and
therefore distributed freely along the entire bus, meaning the bus sections can be signi cantly reduced (if the
electric loads are suitably balanced) and guaranteeing - where necessary - a backup system which is easy to create.
