Tone Selection and 2nd and 3rd Stage Alarms
The BExS120D and BExS110D sounders have 32 different
tones that can be selected for the first stage alarm. The
sounders can then be switched to sound second and third
stage alarm tones. The tones are selected by operation of a
DIP switch on the pcb for both DC and AC units. The tone
table on page four shows the switch positions for the 32
tones and which tones are available for the second and third
stages. To operate the sounder on stage one simply connect
the supply voltage to the normal supply terminals (+ve and –
ve for DC units, L and N for AC units).
The operation of the second and third stages is different for
DC and AC units.
DC Units Second and Third Stage Tone Selection
The BExS120D and BEx110D DC sounders have the facility
to use ve or –ve switching to change the tone to the
second and third stages. For –ve switching connect the two
headers on the pcb to the left-hand (marked –ve) and centre
pins. For +ve switching connect the headers to the right hand
(ve) and the centre pins. To change to the second
stage tone, connect either a -ve or +ve supply line to terminal
S2, depending on which switching mode is being used while
maintaining the dc supply to the +ve and –ve terminals.
Similarly for the third stage tone, connect a -ve or +ve supply
line to terminal S3. The supply to 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 BExS120D
and BExS110D AC sounders the Common (C) terminal on
the three way terminal block on the pcb is connected to the
S2 terminal for the second stage tone and the S3 terminal for
the third stage tone.
15)
Volume Control
All BExS120D and BExS110D 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. For maximum output level the
potentiometer should be set to the fully clockwise position.
16)
End of Line Monitoring (DC Units)
On BExS120D and BExS110D DC units, 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 +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.
