PRE-INSTALLATION
WARNING - Before the E2xS121UL sounder is installed the
required tone and output volume must be set. Note the units
are factory set to tone 2 (800/1000Hz alternating at 2Hz) and
maximum output. If necessary the unit should be connected to
a suitable power supply in a safe area to determine what tone
pattern and output level is required.

WARNING – DO NOT OPEN WHEN ENERGISED
CAUTION - DO NOT OPEN WHEN AN EXPLOSIVE GAS
OR DUST ATMOSPHERE IS PRESENT
WARNING - EXPLOSION HAZARD - SUBSTITUTION OF
COMPONENTS MAY IMPAIR SUITABILITY
FOR CLASS I, II DIVISION 2.
MOUNTING
The E2xS121UL sounder must be mounted using the rotating
bracket as shown. If the cover has been removed to set the tone
or volume control ensure that it has been correctly replace
before the sounder is mounted.

WIRING INSTALLATION
The E2xS121UL sounder is provided with 2 off M20 x 1.5 cable
entries.
1 x ½” NPT adaptor and 1 x M20 stopping plug are provided.
Installation using Field Wiring Leads and Conduit
If the sounder is supplied pre-wired with flying leads, these are
colour coded and should be connected as shown in the diagram
below.
The conduit running from the supply to the sounder must
include an equipment grounding conductor that is at earth
potential to facilitate ground connection of the device. A number
of sounders can be connected in a chain to the same supply
using field installed wiring compartments that are appropriate for
the hazardous location, provided that the conductor at earth
potential can be readily connected to the ground lead on each
sounder in the chain.
Installation using Cable Glands without Field Wiring Leads
If the sounder is supplied without field wiring leads, the cable
connections are made into the terminal blocks on the electronic
PCB assembly. Terminal blocks are suitable for field wiring
(AWG 18-12). Strain relief has to be ensured by installation with

a suitable cable gland. Follow the markings for the terminals
on the PCB and install wiring as shown in the diagram below.
Cable glands need to be UL certified to ANSI/UL 2225 or
C22.2 NO. 174-M1984. and to UL514B / CSA-C22.2 No. 18.3-
12, ratings for hazardous locations must be equal to or better
than the rating of the sounder used.
If a high IP (Ingress Protection) rating is required then a
suitable sealing washer must be fitted under the cable gland.
WARNING - ALL ELECTRICAL WIRING MUST BE
INSTALLED IN ACCORDANCE TO THE

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.
Unit Type Input Input @ 1kHz Max.
Voltage Current I/P Volts
E2xS121UL 24V DC 280mA 30V
E2xS121UL 48V DC 215mA 58V
E2xS121UL 230V 50/60Hz AC 76mA 253V
E2xS121UL 120V 50/60Hz AC 142mA 132V
TONE SELECTION
The E2xS121UL 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
flying leads (Red and Black for DC units, Black, White and
Green/Yellow 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 S2 orange
wire to the negative supply. To activate the third stage,
remotely switch the S3 orange wire to the negative supply.
NOTE the DC power supply to the Red and Black wires must be
maintained for 2nd and 3rd stages.
AC Units Second and Third Stage Tone Selection
To select the second and third stages on the E2xS121UL AC
sounders the Common (C) Violet wire must be remotely
connected to the S2 orange wire for the second stage and to
the S3 yellow wire for third stage. NOTE the AC power supply to
the Black and White lead must be maintained for 2nd and 3rd
stages.
VOLUME CONTROL
The volume on the E2xS121UL sounder can be set using the
volume control (see figures 2 and 3). 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
END OF LINE MONITORING
On E2xS121UL 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 resistor can be
connected across the +ve and –ve terminals. If an end of line
resistor is used it must have the following values:-
24V DC Sounders
Minimum Resistance 3k9 ohms Minimum wattage 0.5W
Minimum Resistance 1k ohms Minimum wattage 2.0W
48V DC Sounders
Minimum Resistance 15k ohms Minimum wattage 0.5W
Minimum Resistance 3k9 ohms Minimum wattage 2.0W
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 inch
(1.58mm) must be provided through air and over surfaces
between uninsulated live parts.
