DESCRIZIONE DESCRIPTION
La scheda (fig. 1) è parte integrante della centrale di controllo degli impianti antincendio. E' dedicata alla supervisione del sistema e alla gestione delle segnalazioni comuni, sia visive che di attivazione. La scheda è sempre presente nel sistema, installata nello slot S-Y del RACK SIA-R. The board (fig. 1) is an integral part of the control unit of the fire-fighting systems. It is dedicated to the supervision of the system and to the management of common signals, both visual and activation. The card is always present in the system, installed in the S-Y slot of the SIA-R RACK.
Su fronte scheda sono presenti le segnalazioni luminose relative a guasti o stati generali della centrale. On the front of the board there are the luminous signals relating to faults or general states of the control unit.
Un circuito a MOS relè con amplificazione differenziale controlla eventuali dispersioni di corrente tra il positivo (+24VDC) e terra e tra negativo (0V) e terra. A MOS relay circuit with differential amplification checks for any current leakage between positive (+ 24VDC) and ground and between negative (0V) and ground.
6 linee configurabili come ingresso o uscita forniscno segnalazioni generali che possono essere utilizzate nelle logiche di programmazione della centrale, n. 4 di queste, se configurate come linee di uscita di trasmissione stato, soddisfano il requisito dalla EN 12094-1 per le segnalazioni cumulative delle zone di scarica. 6 lines configurable as input or output provide general signals that can be used in the programming logic of the control panel, n. 4 of these, if configured as status transmission output lines, meet the requirement of EN 12094-1 for cumulative signaling of discharge zones.
La scheda monitora tramite circuiti integrati dedicati temperatura e umidità, fornendo adeguate segnalazioni di guasto alla CPU della centrale nel caso i valori ambientali escano dall'intervallo di funzionamento predefinito. The board monitors temperature and humidity via dedicated integrated circuits, providing adequate fault signals to the control unit CPU in case the environmental values go out of the predefined operating range.
La scheda è dotata di due relè con contatto di scambio per la segnalazione di stato di allarme e guasto generale della centrale. Lo stato di attivazione dei relè è monitorato secondo le prescrizioni della IEC61508. The board is equipped with two relays with exchange contact for signaling the alarm status and general failure of the control panel. The activation status of the relays is monitored according to the requirements of IEC61508.
Un'uscita open collector comanda il buzzer della centrale, mentre un uscita supervisionata realizza il dispositivo tipo C della EN54-2 (sirena tacitabile). Il monitoraggio della linea di attivazione della sirena è realizzato in modo innovativo per il settore con tecnica congiunta DMOS+LVL (doppio mos di linea e bassa tensione di controllo) che permette di controllare gli attuatori senza la necessità di aggiungere elementi di terminazione in campo. An open collector output controls the control panel buzzer, while a supervised output realizes the EN54-2 type C device (silenceable siren). The monitoring of the siren activation line is made in an innovative way for the sector with the combined DMOS + LVL technique (double mos of line and low control voltage) which allows to control the actuators without the need to add termination elements in the field.
Un circuito di switch integrati gestisce la direzione dei bus seriali (COMI, 2, 3, 4) e del bus di comando del pannello operatore (Display LCD Touch-screen) a seconda del funzionamento delle CPU ridondate in centrale. A circuit of integrated switches manages the direction of the serial buses (COMI, 2, 3, 4) and of the control bus of the operator panel (LCD Touch-screen display) according to the operation of the redundant CPUs in the control panel.
Per centrali a CPU ridondata, la scheda controlla il funzionamento delle CPU e ne determina la priorità in caso di fail di una delle due unità principali. For redundant CPU control units, the board checks the operation of the CPUs and determines their priority in the event of a fail of one of the two main units.
Per centrali a CPU singola, la scheda supervisiona il funzionamento (Watchdog) dell’unità principale. For single CPU control units, the board supervises the operation (Watchdog) of the main unit.
Il bus di comunicazione tra la scheda 5319-Y e le CPU è un bus a 3 linee (SYNC, DATA, CLOCK), tipo bus i2c ma con protocollo “customizzato". Il bus è ridondato. The communication bus between the 5319-Y board and the CPUs is a 3-line bus (SYNC, DATA, CLOCK), type i2c bus but with “customized” protocol. The bus is redundant.
Le morsettiere degli IO della scheda sono su RACK SIA-R. The board's IO terminal blocks are on SIA-R RACK.
