Volume Control; Tone Selection - E2S D2xC2LD2 Series Instruction Manual

12) End Of Line Monitoring (DC Units Only)
On DxC2 DC units, dc reverse line monitoring can be used if
required. All DC units have a blocking diode fitted in their
supply input lines. 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 the following values:-
Min. Resistance
3.9KΩ
24V DC
15KΩ
48V DC
3.9KΩ
The resistor must be connected directly across the +ve and
-ve terminals of the sounder board, as shown in the following
drawing. Whilst keeping its leads as short as possible, a
spacing of at least 1/16 inch (1.58mm) must be provided
through air and over surfaces between uninsulated live parts.

For the Beacon, the resistor must be connected directly
across the +ve and -ve terminals as shown in the following
drawing. Form the resistor legs as shown in Fig. 7, remove
the +ve and –ve terminal plugs and fit the resistor across the
two terminal plugs before refitting them to the PCBA as shown
in Fig. 8. A spacing of at least 1/16" (1.58mm) must be
provided through air and over surfaces between uninsulated
live parts.

13) Setting

13.1. Volume Control

The alarm horn output level of the DxC2 unit can be set by
adjusting the volume control potentiometer (see Fig 2). For
maximum output, set the potentiometer fully clockwise.

13.2. Tone Selection

The DxC2 alarm horns have 64 different tones. The tones are
selected by operation of the tone setting DIP switches (see Fig.
2) on the PCB. The alarm horns can also be switched to sound
the second, third and fourth stage alarm tones. The tone table
(Table 1) shows the switch positions for the 64 tone and which
tones are available for the second, third and fourth stages.
13.3. Flash Rate Setting
The D2xC2LD2 beacons can produce different flash patterns as
shown in Table 1. The flash patterns are selected by operation
of the flash setting DIP switch on the PCB, Fig 6.
