WIRING:
See Pict. 1 and connect the positive output of the control panel (delivering min. 55mA 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. Also connect the negative to
GND terminal as shown in Pict. 1.
To adjust the sound pressure (from 80 dB to 103 dB), 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.
SOUNDER INPUT: +13.8 Vdc
BI-TONE INPUT: +13.8 Vdc
INPUT FOR SOUND SOFTENING: +13.8 Vdc
POWER SUPPLY: NEGATIVE

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. Insert a screwdriver in the hole as shown in Pict. 2 and gently exert a slight pressure to lift the cover up a bit;
2. Take off the cover;
3. Fix the sounder on the wall through the 4 fixing holes located on the sounder base (see Pict. 3) and using 4 5-mm wall plugs (see
Pict.3);
4. For the wiring: use a joint in case of installation with external pipes.
