System description

An Alarm System consists of a Central Unit (CU) that manages a certain number of inputs

(typically connected to sensors and detectors, called zones), outputs (connected devices

such as sirens, indicators, etc.) and other devices (i.e. RFID keys, Smartcards, Expansion

Modules, GSM, Keyboards, RF module, etc.) connected to the communication bus for

system management and configuration as shown in Figure 1.

The system is controlled using up to 8 Control Modules that regulate system installation,

parameter configuration and switching on/off the CU and partitions.

Each zone of an alarm system can be configured, logically regrouped, separately processed

and associated to a group of outputs in a different way. The outputs are also configurable in

terms of timing, working mode and normal status (High or Low).

This CU is composed of 8 zones directly hard-wired to the CU board. It is possible to expand

the number of zones by connecting one or more I/O Expansion modules through the bus.

Seven hardwired outputs are available:

●

Four outputs are separately driven by a solid state relay (SSR - VN340SP) and can

deliver up to 1A for each output. These outputs are normally used for connecting sirens

and other external devices (auxiliary outputs).

●

Two outputs are transistorized and typically used for indicating the system status (alarm

condition, CU status, etc.).

●

One output is a micro relay for general purpose uses such as connecting a video

recorder, external GSM, etc.
