The resistor must be connected directly across the +ve and
-ve terminals as shown in the following drawing. Whilst
keeping its leads as short as possible, a spacing of at least
1/16” (1.58mm) must be provided through air and over
surfaces between uninsulated live parts.

11.1 Tone Selection
The sounders have 45 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 six shows the switch
positions for the 45 tones and which tones are available for
the second and third stages. To operate the sounder on
stage 1 simply connect the supply voltage to the normal
supply terminals (+ve and –ve for DC units, L and N for AC
units).
11.2 Volume Control
The output level of the E2x sounder can be set by adjusting
the volume control potentiometer (see Fig 4 for AC & Fig 6 for
DC). For maximum output, set the potentiometer fully
clockwise.
12) Maintenance, Overhaul & Repair
Maintenance, repair and overhaul of the equipment should
only be carried out by suitably qualified personnel in
accordance with the current relevant standards:
EN60079-19
IEC60079-19
Explosive atmospheres - Equipment repair,
overhaul and reclamation
EN 60079-17
IEC60079-17
Explosive atmospheres - Electrical
installations inspection and maintenance
To avoid a possible ELECTROSTACTIC CHARGE the unit
must only be cleaned with a damp cloth.
Units must not be opened while an explosive atmosphere is
present.
If opening the unit during maintenance operations a clean
environment must be maintained and any dust layer removed
prior to opening the unit.
