Stop Terminal
The user can remotely activate and deactivate the
BExH120D Hootronic DC sounder by switching a connection
from the “Stop” terminal to the –ve or +ve supply lines,
depending on which switching mode is being used +ve or –ve
(see above) whilst the unit is powered. To achieve the “tail
off” sound at switch off the unit must remain powered.
AC Units Second and Third Stage Sound Selection
To select the second and third stage sounds on the
BExH120D Hootronic AC sounder the Common (C) terminal
on the four way terminal block on the pcb is connected to the
S2 terminal for the second stage sound and the S3 terminal
for the third stage sound.
Stop Terminal
The user can remotely activate and deactivate the
BExH120D Hootronic AC sounder by switching a connection
between the “Stop” terminal to the “C” terminal whilst the unit
is powered. To achieve the “tail off” sound at switch off the
unit must remain powered.

Volume Control
The BExH120D Hootronic sounder has a volume control to
adjust the output level. To set the required output level,
adjust the potentiometer on the pcb. For maximum output
level the potentiometer should be set to the fully clockwise
position.
17)
End of Line Monitoring (DC Units)
On BExH120D Hootronic DC units, dc reverse line monitoring
can be used if required. The DC unit has a blocking diode
fitted in their supply input lines. An end of line monitoring
diode or an end of line monitoring resistor can be connected
across the +ve and –ve terminals. If an end of line resistor is
used it must have a minimum resistance value of 3k3 ohms
and a minimum wattage of 0.5 watts or a minimum resistance
value of 500 ohms and a min. wattage of 2 watts.
