12.1 Tone Settings
The 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 D210-95-001-IS 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).
Refer to wiring schematics D210-06-001 (DC) or D210-06-005
(AC).

12.2 Pulse Tone Operation
The BExTS110D Sontel has two modes of operation,
continuous tone operation and pulsed tone operation.
To select continuous tone operation the pulse tone header pins
should not be shorted. In this mode the output tone will be as
per the tone table.
To select pulse tone operation, the pulse tone header pins
should be shorted. In this mode of operation the selected tone
pattern will pulse on and off following the telephone input
signal.
Note if pulsed tone operation is selected it is advisable not to
select any of the intermittent tones, such as tone 11.

13. 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 Explosive atmospheres - Equipment
IEC60079-19 repair, overhaul and reclamation
EN 60079-17 Explosive atmospheres - Electrical
IEC60079-17 installations inspection and maintenance
The acoustic horn is made out of ABS plastic, therefore 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.
