SR 133
1. INTRODUCTION
ENGLISH
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).
3. INSTALLATION
ᇐ
configure jumpers J11, J12 and LAUNCHING according to siren starting mode.
ᇐ
connect the 12VDC 2Ah buffer battery to the red and black wires with faston (in case of “launching” starting mode,
there is no battery);
ᇐ
connect external 13.8 VDC power supply to the SUPPLY terminals (*);
ᇐ
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);
ᇐ
the anti-opening/tearing contact must be connected to the relevant circuit of the alarm unit through the TAMPER
contacts;
ᇐ
time the trimmer to desired sound and flash;
ᇐ
close the metal cover using the screws provided
ᇐ
close the siren by means of the plastic cover.

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.
