Operating Instructions:
The desired function is switched on or off by pressing
the respective buttons.
The volume of a communication is adjusted via
external potentiometer.
Communication from front to exterior
Press button „communication front > < exterior“,
front LED is on.
Version 797101
Press button „communication front > < exterior“
or press and hold down button „PTT“.
Communication from rear to front
Press button „communication rear > < front“,
front and rear LEDs are on.
Communication from rear to exterior
Press button „communication rear > < exterior“,
rear LED is on.
Communication from exterior to front and rear
(listen)
Press button „communication exterior > rear and
front“, front and rear LEDs are flashing (500ms on 1s off).
Switching on the gong
Press „call“ button, front and rear LEDs are on
during the gong signal is heard, then they are
flashing (500ms on - 500ms off).
Switching the siren on
Press button „siren“
Switching the siren off
Wait at least 2s, then press and hold down „siren“
or any other button till the siren is switched off.
Starting the system:
Tune the external potentiometer to the maximum or
bridge over pins 24 and 26.
Press button „communication front > < exterior“,
or hold button down (version 797101).
Tune potentiometers „exterior volume“ and „front
volume“ for desired exterior and interior volume.
In case of „push to talk“ mode (potentiometer
„balance“ < 6) hold down button „PTT“ to adjust
the „exterior volume“. Tone colour can be modified
by tuning potentiometers „treble“ and „bass“.
Press button for „communication rear > < front“
Tune potentiometer „rear volume“ to reach desired
rear volume.
Press „call“ button
Tune potentiometer „gong“ for desired volume.
The position of the potentiometer „balance“ affects
front, exterior and rear volumes, depending on the
operating mode. Together with the „PTT“ button the
operating mode changes from open duplex to simplex.
Communication front > < exterior
Tune potentiometer „balance“ towards zero to
decrease the exterior volume, press and hold the
„PTT“ button to decrease front volume.
Communication rear > < front
Tune potentiometer „balance“ towards zero to
decrease front volume, press and hold the „PTT“
button to decrease rear volume.
If the „balance“ potentiometer is turned to the ultimate
right-hand position, volume can´t be influenced by
pressing the „PTT“ button.
