OPERATION
The Ness Radio Siren is designed to be installed
indoors as a wireless internal siren. This provides
the convenience of an extension siren without
the trouble of cabling between the control panel
and the siren.
For an external siren option the RSS Satellite
model has provision for an optional wired horn
speaker and strobe light to be cabled off the
internal unit.
The Radio Siren can program up to 8 radio
devices, meaning it can receive signals from
more than one control panel or from other Ness
radio devices such as Radio Keys, Radio Smoke
Detectors and Radio PIRs.
Both models are powered by a 17VAC plug pack
and the RSS Satellite model has an internal
backup battery for independent operation in case
of mains failure.
INSTALLATION
Mark a level reference line on the wall in the
position you will be installing the Ness Radio
Siren. See Diagram 1.
Line-up the reference mark with the Level
Reference slot in the base plastics.
Secure the base to the wall using the mounting
hardware provided.
Attach the provided spring to the tamper switch.
See Diagram 2.
Feed the plug pack cable through the cable
entry hole in the base and connect the two
17V AC wires to the 17V AC terminals on the
Radio Siren board. Polarity is not observed. The
earth wire is not used.
Insert the battery in the battery holder in the
base plastics and plug the battery leads into
the Battery terminal on the Radio Siren board.
(RSS Satellite model only).
The Radio Siren will be in program mode as
soon as power is applied with the tamper
switch unsealed. At this stage, if you need to
program radio devices, follow the programming
instructions in this manual.
Once programming is complete, attach the
Radio Siren cover to the base and secure it with
the screw provided. Double check to ensure the
plug pack is turned on.

Tamper:
The onboard tamper switch is connected to a 24 hour input and it must be sealed in normal
operation. There is also a terminal provided for connection of external tamper switch and
this terminal input must be terminated with a 2k2 EOL resistor even if unused.
Zone:
The zone input must be terminated with a 2k2 EOL resistor even if unused when operating
as a mini alarm panel mode.
In siren mode add the 2k2 EOL resistor to operate as reset mode.
Outputs
External Siren:
The radio siren capable of driving one 8ohm/4ohm horn speaker and its time out period is
preset to 5minutes.
Strobe:
Strobe output will time out after 11 hours. If mains power is off, the output will time out after
1 hour.
LED Operation:
Double fast flash every 2 seconds during program mode, one fast flash every 2 seconds to
indicate normal operation and continuous flash for low battery condition.
Battery:
The back up battery is float charged at 13.5V - 13.8V.

* RSS Satellite model only
PLUG PACK
The plug pack supplied must always be plugged
into a mains power outlet.
The RSI Siren is solely powered by the plug
pack.
The RSS Satellite uses mains power for normal
operation and to float charge the backup
battery.
ONBOARD SIREN
The onboard siren can output either an Alarm
sound or Fire sound depending on the type of
signal it receives from the transmitting device.
EXTERNAL ANTENNA
The Radio Siren has an internal antenna which
should provide excellent radio range in most
cases.
An external antenna is also supplied and can be
fitted in cases where local radio conditions may be
reducing or interfering with the radio signal.
Please note that if the RF conditions are particularly
adverse, the external antenna may not improve
reception.
OUTPUTS (RSS Satellite model only)
SIREN: The external siren output can drive
2 x 8 Ohm horn speakers. The siren sound can
be either the Alarm Siren or Fire Siren depending
on the type of signal received. The siren timer is
fixed at 5 minutes.
STROBE: The external strobe output can drive
1 x standard mini strobe light.
The strobe output turns on when a Strobe On
message is received and turns off when it receives
a Strobe Off message or after maximum run time.
The strobe will also turn on when the siren turns on
even without a Strobe On message, but in this case
the strobe turns off with the siren. Maximum run
time is 11 hours or 1 hour if mains power is off.
Note: In Strobe Mode, the strobe output is designed
to drive a strobe light only. However the output can be
configured as a Reset output if needed, see below.
RESET MODE: To convert the strobe output into
a Reset output, connect a 2k2 EOL resistor on the
Z1 input (across Z1 & 0V).
The strobe output will now reset after 5 minutes,
and the output voltage will be suitable to drive a
device such as a piezo screamer.
This option is useful in cases where you need
an additional wired internal screamer or even
a screamer/strobe combination on the same
output.
BATTERY (RSS Satellite model only)
If mains power is off, the battery can power the
siren and strobe for one alarm activation.
The battery is tested under load every hour. Low
battery condition is indicated by the LED flashing
continuously.
Note that when mains is restored after a power
failure, the LED will continue to flash for several
hours until the battery reaches full charge.
INPUTS (RSS Satellite model only)
EXTERNAL TAMPER: The 24hr Tamper input
terminals are provided for connection of an
external tamper if using the external siren option.
The Tamper input must be terminated with a 2k2
End Of Line resistor even if unused.
ZONE: The Zone input should normally be left
unconnected unless you need require the Strobe
output to operate in Reset mode, (See RESET
MODE).

PROGRAMMING
Programming of transmitters to the Radio Siren
is a simple two-step process.
1. ENTER PROGRAM MODE
To enter Program Mode, power-up the Radio
Siren with the internal tamper unsealed. The
Radio Siren will then be in learn mode for 30
seconds or until programmed. Program Mode is
indicated by the LED double flashing.
Once in program mode, resealing the tamper
will exit program mode immediately.
2. LEARNING TRANSMITTERS
Send a Learn Message from the radio device/
transmitter that will operate the Radio Siren.
The siren will chirp twice + double-chirp to
acknowledge it has successfully learned the
transmitter’s code.
As soon as the radio device is programmed,
the Radio Siren will automatically exit program
mode.
MESSAGE TYPES
The internal siren (and RSS model external
siren output) can output different siren sounds
depending on the type of message received.
The Ness RST Radio Siren Transmitter can send all
message types understood by the Radio Sirens.

be programmed to the Radio Siren.
(Program other devices such as Radio PIRs or
Radio Keys for special purposes such as stand-
alone use.)
PROGRAMMING ADDITIONAL DEVICES
To program a second device, remove power from
the Radio Siren (mains and battery) then power-up
and repeat Step 2 above.
Up to 8 devices can be programmed.
Programming a 9th device will erase the 1st
device so that there are no more than 8 devices
programmed.
