Installing the Siren
Step 1 –Choose a Location for the Siren
Choose a location that is:
Out of reach of intruders and vandals.
Easily visible for maximum deterrence.
Within the allowable cable distance
(see Cable Recommendations on page
9).
Step 2 –Open the Lid of the Siren
1. With the siren not yet fixed to the wall,
open the hinged cover that gives
access to the lid-retaining screw (see
Figure 2).
2. Loosen the screw and open the lid.
Step 3 –Configure the Siren Jumpers
1. Remove the link/terminal cover (see
Figure 2) by pushing the two retaining
tabs to the side of the unit while lifting
the cover.
2. Set all jumpers in the siren to the
required positions (see Quick
Reference on page 4).
Step 4 –Disconnect all Power
Make sure that all power to the control unit
is disconnected, including the backup
battery. Also make sure that the battery in
the siren is not connected.
Step 5 –Install Cabling
Install all cabling between the control
unit/expander and siren (see Cable
Recommendations on page 9). Connect the
cabling at the control unit/expander end, but
leave the siren unconnected for now. Note:
To prevent water ingress, cables must enter
the cable-entry hole at the siren (see Figure
2) from below.
Step 6 –Attach the Siren to the Wall
1. Position the siren against the wall using
the built-in spirit level to assist levelling,
and mark all four fixing points.
2. Drill and plug the fixing points using the
screws and plugs provided.
3. Pass wiring through the cable-entry
hole.
4. Screw the siren to the wall. Use the
spirit level and revolving guides to
correct any misalignment.
Step 7 –Connect the Siren Wiring,
Power Up and Close the Lid
Note: The sounder should not activate
during the following process. However, be
prepared in the event that it does
activate; make sure that any very loud
noise produced cannot cause a fall.
1. Connect all wiring to the siren (see
Quick Reference on page 4).
2. Connect the siren battery (see Figure
1).

Page 3
The siren should power up in "silent
startup" mode, which is indicated by the
comfort LEDs remaining solidly lit.
3. Re-fit the jumper/terminal cover, close
the lid, tighten the lid-retaining screw
and close the screw cover.
(The LEDs will remain solidly lit and the
siren will not go into normal mode until
power is applied to the control unit.)
Step 8 –Power-up and Configure the
Control Unit
1. Connect the backup battery in the
control unit.
2. Switch on power to the control unit. A
siren tamper alarm may be indicated.
3. Configure the control unit. If you are
using an i-on or Menvier control unit,
you need to carry out the following for
the siren:

Connection Details
TR
The TR terminal provides the control unit
with the tamper status of the siren. TR is
activated (and the siren self-activates) if
any of the following occurs:
a) The siren's tamper switch is activated.
b) The BELL input from the control
unit/expander is cut, providing the Trig
Mon link (page 7) is fitted (SDR-WEXT-
G3 only).
c) Power from the control unit/expander is
disconnected.
When using the SDR-WEXT-G2, TR is 0V
in normal operation, and switched to open
circuit when a tamper is detected.
When using the SDR-WEXT-G3, the
voltage and termination of the TR terminal
must be configured using the Tmp Feed
jumper (see page 8).
ENG (Installer Mode)
Setting the ENG input to 0V sets the siren
in installer (engineer) mode. You should
normally connect ENG to a control
unit/expander output configured as type
"Installer on Site", which activates when
entering the Installer menu at a keypad and
deactivates when exiting the Installer menu
(at every keypad).
Installer mode prevents the sounder and
strobe from activating when the lid is
opened.
When installer mode is activated, both
comfort LEDs switch on continuously for a
few minutes.
STR and BELL
0V at the STR (strobe) input activates the
strobe. 0V at the BELL (trigger) input
activates the sounder. Some control units
provided dedicated strobe and bell outputs.
If not (or an expander is used), connect to
outputs of type "Strobe" and "Siren"
respectively.
F-F and F-R and RST
The SDR-WEXT-G3 provides F-F (Fault
Feed) and F-R (Fault Return) volt-free
terminals, which are used to provide
sounder and battery fault reporting to the
control unit.
To enable sounder and battery fault
reporting, see Quick Reference on page 4
for connection and configuration details.
Technical Detail for Advanced Installers
The siren tests the battery voltage under
load conditions every hour and when the
ENG input is deactivated. The sounder is
tested each time it is activated. Under
normal conditions, F-F and F-R are closed
circuit. If either test fails, F-F and F-R go
open circuit, which causes the control unit
to generate an alarm. The contacts remain
open circuit until the test is successful or
the siren's tamper switch is activated (in the
latter case, the siren assumes that an
engineer is fixing the problem).
A sounder or battery fault may prevent the
system from being set (depending on
grade) and cannot be cleared until the
siren's tamper switch is activated, or the
test is performed again and passes.
You can start a test manually by using the
Installer Menu –Test –Sirens & Sounders
–Wired Sirens –Remote Self-Test , which
tests both the sounder and battery.
When Remote Self-Test is used, the RST
(Remote Self-Test) input is set to 0V for the
duration of the test. This causes F-F and F-
R momentarily to go open circuit, which
confirms to the control unit that the siren is
healthy. If the siren passes, F-F and F-R go
closed circuit (normal state) within 60
seconds. The siren fails the test if the
contacts remain open after 60 seconds or if
the control unit does not detect the open
circuit at the start of the test.
A remote self-test occurs only when RST is
0V; setting RST to 12V or leaving it
unconnected disables remote self-test.

Page 7
TF
The SDR-WEXT-G3 has a TF (Tamper
Feed) terminal, which should be used only
if a Tmp Feed link is not fitted. TF and TR
go open circuit on a tamper condition; the
normal state is open circuit.
PCB Jumper Details
SCB/SAB
In SAB (Self-Activating Bell)
mode, which is the typical
choice, the siren draws all its
power from the control
unit/expander. The internal
battery is used only if power
from the control unit/expander
is disconnected.
In SCB (Self-Contained Bell)
mode, all power to operate the
siren when in a non-alarm state
is drawn from the control
unit/expander. When in an
alarm state, the siren sources
power from its own internal
battery. Typically, SCB mode is
used if the control
unit/expander is not able to
provide sufficient power (e.g. if
multiple sirens are used).
Trig Mon
The SDR-WEXT-G3 has a Trig Mon
(Trigger Monitor) jumper. Fitting a link
allows the siren to monitor the BELL input
for tamper conditions (e,g, caused by the
wire being cut). If a BELL tamper condition
is detected, the sounder and TR output
activate.
The output at the control unit/expander
end of the cable requires a 4k7 pull-up
resistor (between the output and 12Vdc ).
This is provided by default if you are using
an open-collector transistor output from an
i-on, Menvier or Scantronic control
unit/expander (such as provided by the
BELL output). If a relay-type output is used,
you need to add the resistor yourself. If you
are using an open-collector output from
another type of control unit and want to
check for the presence of a 4k7 pull-up,
temporarily connect a separate 4k7 resistor
between the output and 0V; if a 4k7 resistor
is present, the voltage at the output should
be half of the supply voltage to the siren
(typically 6.9Vdc).
The jumper setting is read when power is
applied or the lid is opened.
Tone Slct
Fit a link across Tone Slct (Tone Select) or
leave it disconnected to choose one of two
tones from the sounder. You may want to
use this feature if, for example, you want to
be able to distinguish two sounders that are
in close proximity.
Time
The Time (Cut-Off Timer) jumper
configures the maximum length of time the
sounder operates following an alarm (even
if the BELL input is still active). Choose 5
seconds, 3 minutes or leave the link
disconnected for a default cut-off time of 15
minutes.
Note: To reactivate the sounder, the BELL
input must be taken to 12V for at least two
seconds before 0V is reapplied.
The jumper setting is read when power is
applied or the lid is opened.
LED En
Fit a link across LED En (LED Enable) to
enable the comfort LEDs. The jumper
setting is read when power is applied or the
lid is opened.
During normal operation, the comfort LEDs
flash alternately when the siren has power
connected to give a visual indication that
the system is operational.
When installer mode is activated, both
comfort LEDs switch on continuously for a
few minutes. The comfort LEDs also switch
on continuously during the silent startup
period between connecting the battery and
10 seconds after closing the lid.

Page 8
Tmp Feed
The SDR-WEXT-G3 contains a Tmp Feed
(Tamper Feed) jumper, which determines
the voltage of the TR terminal and how the
sounder terminates TR, as described next.
EOL Setting
This setting ("eol") causes TR
to connect to 0V through a 2k2
on-board resistor.
Use the "eol" setting if:
You connect TR to a dedicated
bell/strobe TR input at the control unit,
and the input is programmed (see Note
1) to use FSL wiring.
Note 1: In i-on/Menvier systems, using
Installer Menu –System Options –
Panel Tamper Rtn.
"-" Setting
This setting ("-") causes TR to
connect directly to 0V.
Use the "-" setting if:
You connect TR to a dedicated
bell/strobe TR input at the control unit,
and the input is programmed (see Note
1 above) to use CC wiring.
You connect TR to a zone that is
configured as type "Tamper Return".
"+" Setting
This setting ("+") causes TR to
connect to 12V through a 1k0
on-board resistor. This may be
required for third-party panels.
"No link" Setting
When no link is fitted, TR
connects directly to TF.
Use the "no link" setting if:
You connect TR and TF to a zone
configured as type "Tamper Return".
You wish to fit an alternative in-line
resistor of your choice between TR and
12V/0V.
Fault and Tamper Monitoring
The siren monitors the following:
Tamper conditions –All tamper
conditions reported by the TR terminal
(see page 6) are continuously
monitored. The siren self-activates on
a tamper.
Battery voltage (SDR-WEXT-G3 only)
–The siren monitors the battery
voltage under load conditions and
reports a fault during a remote self-test
and at other times (see page 6).
Sounder operation (SDR-WEXT-G3
only) –If the F-R output is used, the
siren checks that the sounder is
audible during a remote self-test (see
page 6) and when operated.
Summary of Strobe Operation
The strobe operates if the siren self-
activates or if the control unit/expander sets
the STR input to 0V.
After 15 minutes of the siren being
activated, the strobe flashes at a slower
rate until the alarm is reset.
In i-on/Menvier systems, the strobe can
also be configured using the Set Conf link
and the Strobe on Set/Unset options (see
"PCB Jumper Details").
Maintenance
NOTE: Start installer mode (page 6) before
opening the lid of the siren. This should
prevent the sounder from activating.
However, be prepared in the event that
the sounder does activate –make sure
that any very loud noise produced
cannot result in a fall.
During routine maintenance, test the siren
for correct operation, carry out a remote
self-test (see page 6), check the tamper
switch and for any signs of water or insect
ingress and clean as necessary.

Page 9
NOTE: Equipment must be disposed of in
accordance with WEEE regulations and any
other local or national regulations.
Cable Recommendations
Standard 7/0.2 un-screened alarm cable
should be used.
The maximum recommended cable
distance is 50m if you are using SAB mode
and only TR for tamper monitoring (i.e. not
both TR and TF). This can be increased to
100m by doubling the 0V cores.
The maximum recommended cable
distance is 100m if you are using SCB
mode, or both TR and TF for tamper
monitoring.
