POWER SUPPLY SELECTION
It is important that a suitable power supply is used to run the
sounders. The power supply selected must have the
necessary capacity to provide the input current to all of the
sounders connected to the system.

TONE SELECTION
The E2xS121EG 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 opposite 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 one simply connect the supply voltage to
the + & – terminals for DC units and the L, N & E terminals
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
To activate the second stage, remotely switch the negative
supply to the S2 terminal. To activate the third stage,
remotely switch the negative supply to the S3 terminal.
NOTE the DC power supply to the + & - terminals must be
maintained for 2
nd
and 3
rd
stages.
AC Units Second and Third Stage Tone Selection
To select the second and third stages on the E2xS121EG AC
sounders the Common (C) terminal must be remotely
connected to the S2 terminal for the second stage and to the
S3 terminal for third stage. NOTE the AC power supply to the
L, N & E terminals must be maintained for 2
nd
and 3
rd
stages.
VOLUME CONTROL
The volume on the E2xS121EG sounder can be set using the
volume control (see pcb layouts on page 1). For maximum
output level the potentiometer should be set to the fully
clockwise position.
WARNING – HIGH VOLUME MAY CAUSE HARM TO
PERSONNEL IN CLOSE PROXIMITY
