Volume Control - E2S BExS120E Manual De Instrucciones

the S3 terminal will automatically override a supply to the S2
terminal.
AC Units Second and Third Stage Tone Selection
To select the second and third stage tones on the BExS120E
and BExS110E AC sounders the Common (C) terminal on
the terminal block in the terminal chamber is connected to the
S2 terminal for the second stage tone and the S3 terminal for
the third stage tone.

16) Volume Control

All BExS120E and BExS110E sounders, with the exception
of 12V DC units, have a volume control to adjust the output
level. To set the required output level, adjust the
potentiometer on the pcb in the flameproof enclosure. See
section 8 of this instruction manual for access to the
flameproof enclosure. For maximum output level the
potentiometer should be set to the fully clockwise position.
17) End of Line Monitoring (DC Units)
On BExS120E and BExS110E DC sounders, dc reverse line
monitoring can be used if required. All DC sounders have 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 terminals provided in the flameproof
enclosure. Note monitoring components must not be
connected to the terminal block in the Increased Safety
terminal chamber. See section 8 of this instruction manual
for access to the flameproof enclosure.
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
minimum wattage of 2 watts.
