1. INTRODUCTION
SR 133 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).
2.REGULATION AND CONTROL
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"
Jumper J12=
"Start with positive"
Connect a 10Kohm resistor between terminal "START" and terminal "-12V"
"Start with negative"
Connect a 10Kohm resistor between terminal "START" and terminal "+12V"
"launching"
Jumper J12=
Jumper 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.
3. INSTALLATION
configure jumpers J11, J12 and LAUNCHING according to siren starting mode.
connect the 12VDC 2Ah buffer battery to the red and black wires with faston (in case of "launching" starting mode,
there is no battery);
connect external 13.8 VDC power supply to the SUPPLY terminals (*);
connect siren start line from the alarm panel to the START terminal (in case of "launching" starting mode, the START
terminal must be connected to the +12V terminal);
the anti-opening/tearing contact must be connected to the relevant circuit of the alarm unit through the TAMPER
contacts;
time the trimmer to desired sound and flash;
close the metal cover using the screws provided
close the siren by means of the plastic cover.
