INSTALLAZIONE
Eseguire in sequenza le seguenti operazioni :
configurare i jumper J11, J12 e LAUNCHING in funzione della modalità di attivazione della sirena;
collegare la batteria tampone da 12 V
collegare l'alimentazione esterna da 13,8 V
collegare la linea "positivo a mancare/dare" o "negativo a mancare/dare" al morsetto START;
i contatti antiapertura e antistrappo sono collegati in serie e devono essere connessi al relativo
circuito della centrale di allarme attraverso i contatti TAMPER;
regolare il trimmer per la temporizzazione del suono e lampeggio desiderati;
chiudere il contro-coperchio in metallo con le apposite viti;
chiudere la sirena con il coperchio in plastica.
ENGLISH
The SR135 is a high-power back-up battery siren (105 dB at 3m) protected against tampering (opening,
tearing off). It features a 10W flasher and a sound/flash timer, variable with adjustable trimmer from 1 min. to 7
min., which trips in case of prolonged alarm (eg. connection cable cutting). It has a first switch-on stop
function to prevent the siren from tripping during installation. (for enabling the siren for normal use it's
necessary to activate/deactivate alarm start).

ADJUSTMENTS AND CONNECTIONS
Trimmer TR1 : sound and flashing timer adjustment from 1' to 7' ± 20%
TAMPER terminals : contact N.C. resistant to opening and rip-off
SUPPLY terminals : 13.8 VDC power supply ( rated )
START terminal :
"positive missing"
"negative missing"
"Start with positive" Jumper J11=
"Start with negative"
"launching"
In the "launching" mode, the "+12v" terminal must be connected to the "start" terminal (no back-up battery)
IMPORTANT:
In the launching mode the siren starts howling as soon as power is supplied at the terminals "supply". In this
mode there is no first switch-on stop function.
