PRODUCT DESCRIPTION:
MINI MARINA L indoor sounder is a device conceived for both acoustic and visual notice in alarm
installations. Technical features: two inputs to activate two different sounds, trimmer, two
dipswitches enabling sound pressure adjustment for the various inputs, input for sound softening
control, high-intensity independent LED flashing unit for optical signalizations.

WIRING:
As shown in Pict. 1, connect the negative to GND terminal and the positive output of the control
panel (delivering min. 80mA and limited to 250mA) to one of the positive terminals (+IN1 and/or
+IN2). According to the terminal connected, the sounder produces a sound type.
To adjust the sound pressure (from 80 dB to MAX), rotate P1 trimmer clockwise.
To control the sound softening directly from the control panel (e.g. to notify a pre-alarm), connect
an auxiliary output of the control panel to LO terminal: when the terminal is brought to a positive
voltage, the sound pressure decreases of around 10 dB. For IN1 and IN2 inputs already to be
softened of around 10 dB (without LO command), set dipswitch 1 (in case of +IN2) and/or
dipswitch 2 (in case of +IN1) in ON position.
When the terminal +LED is brought to a positive voltage, the led DL2 on the sounder flashes
steadily.

MOUNTING:
Attention: the sounder must be installed by qualified staff, in indoor location, keeping into
consideration all related norms and measures and respecting proper distances and installation
heights to the purpose of obtaining the best acoustic and optical notice results from the device.
1. Remove the cover and fix the sounder on the wall through the 4 fixing holes located on the
sounder base (see Pict. 2) and using 4 5-mm wall plugs;
2. For the wiring: use a joint in case of installation with external pipes.
3. Once connection has been performed, close the sounder by screwing the closing screw
through the hole located in the front part of the sounder, as shown in Pict. 3.
