1. Introduction
The 9955 RFX is a Class 6 Radio Expander that allows you to connect up to
eight radio detectors to a 9750 or 9850 system. In addition each expander
also provides for up to six telecommands or PA transmitters.
Figure 1. RFX In Use.
The RFX communicates with the control panel using the same wiring as the
remote keypads. The radio detectors operate on 868.6625MHz.
The RFX can work with the following devices:
a) 719r. A photoelectric smoke chamber type detector.
b) 715r. A Passive Infra Red (PIR) movement detector with 15m standard
range . This detector has a three minute lockout time after detection, in
order to lengthen battery life.
c) 725r. A Remote Setting Device (also known as a “telecommand”) that
can be used to full set, part set or unset the system. The 725r can also
be used as a Panic Alarm.
d) 726r. A small radio transmitter that can be used to start a PA alarm.
e) 735r. A universal transmitter that can be used as a door contact or for
connecting hardwired inputs.
f) 747r. A Go/No Go test meter that provides a simple method for survey-
ing potential radio sites.
g) 746r. A test transmitter used with the 747r for surveying potential user
sites.

Each radio detector and remote setting device contains a digital identity code
that the RFX unit ‘learns’ during installation. The code is one of over 16
million possibilities. This ensures that the RFX unit will not respond to any
other detectors or remote setting switches apart from the ones it has learned.
Figure 2 shows the interior of the RFX unit.
Note: The RFX is designed to work with the 9750 and 9850 control units. Do not
attempt to connect the RFX to any other control unit.

3. Installation
Overview
Installing the RFX comprises the following steps:
1. Carry out a radio site survey and find the best position for the expander
unit.
2. Run a cable from the position of the RFX to the alarm system control
unit or a remote keypad (whichever is nearer).
3. Fit the RFX case back.
4. Connect the RFX to the alarm system control unit.
5. Make the RFX learn the wirefree detectors used for the installation.
All the transmitters designed to work with the RFX have a maximum range of
300m in free space. You must take care when siting these devices. In some
circumstances you may experience a reduction in signal strength to the
receiver. This reduction is called attenuation and can be caused by a wide
variety of natural and man-made hazards.
The most common form of attenuation is that caused by buildings. Some
building materials are more attenuating than others. Metallic surfaces of the
right size can stop all radio signals by reflecting them away from the receiver.
(This also means that sometimes the same surfaces can increase the signal
strength by reflecting more signal towards the receiver.) Wooden surfaces
are almost transparent to radio signals. Brick and stone have attenuations
somewhere between metal and wood. Always carry out a site survey before
starting installation (see below).
The RFX has a built in aerial. Do not attempt to extend the aerial or cut it
from its mounting. If you try to adjust the aerial you will reduce the received
signal strength at the RFX.
All the transmitters, apart from the 725r telecommand and 726r PA, report
every 30 minutes to the RFX. If any transmitter fails to report within 2.5 hours
then the control unit generates an alarm at the keypads and at the Alarm
Receiving Centre (ARC). Do not remove any radio detector from its area
without first deleting its zone number from the control unit.
Radio Site Survey
With a wirefree system we recommend that you carry out radio tests as part
of a site survey to ensure that the RFX can receive the radio signal from the
detectors. If you cannot do the tests during a survey, carry them out before
installation.

You will need a 747rEUR Go/No Go test meter and a 746rEUR test transmit-
ter.
1. Switch the test transmitter on by inserting the batteries. Place the
transmitter at the proposed site for the RFX. The transmitter sends out a
test message every 3.5 seconds. Note: the transmitter shuts itself down
after 30 minutes. To restart, re-insert the batteries.
2. Switch the Go/No Go test meter on and walk around the premises.
3. Hold the test meter at each proposed location for detectors. The test
meter will show a green "Go" LED if the signal strength is adequate.
(You must hold the meter in position for at least 5 seconds.)
4. Move to a different location to improve the signal strength if the meter
shows a red "No Go" LED. Make sure the new location is suitable for
the detector.
5. Change the location of the test transmitter if you cannot find a proposed
detector location with a suitable signal strength. Make sure that the user
agrees to the new location for the RFX.
Note: Do not assume that radio works from every location.
DO site the RFX:
a) In a convenient location to connect to the control unit or a remote
keypad.
b) Within the protected area.
Ensure that there is a clear space around the RFX to allow it to receive a
good quality radio signal.
Do NOT site the RFX:
a) Outside the area covered by the alarm system.
b) Near ground level.
Do NOT site the RFX or detectors:
a) Close to or on large metal structures, for example: metal doors or
frames, water tanks, cars, fridges and freezers.
b) Closer than one metre to mains wiring and metal water or gas pipes.
c) Inside steel enclosures.
d) Next to high voltage electrical equipment, or electronic equipment,
particularly computers, photocopiers or other radios.
Fitting the RFX
The following instructions assume that you have carried out a radio site
survey, found the best position for the RFX, and run the necessary cabling.
1. Remove the RFX unit from its packing.

2. Remove the case lid. Gently press in the lugs at side of the case and
ease the two halves apart.
3. The upper part of the case back provides a central keyway (see Figure
2). Mark and drill a hole for the keyway. Temporarily fix the case back to
the wall. Now mark the position of two more fixing holes, remove the
case back and continue to drill the holes.
4. Refit the case back to the wall using not less than 30mm x No 8 Dome
or Pan-head screws.
Connecting the RFX
Figure 3 shows the connections for the RFX to the alarm system control unit.
Note: use the cable entry at the bottom of the case. Do not feed cable
through the top of the case since this will interfere with the aerial.

Putting the RFX into Learn Mode.
To make the RFX learn transmitters you must connect the unit to a 12VDC
supply. Take the supply from the alarm system control unit by connecting as
shown in Figure 3. Alternatively, you can power the RFX temporarily by
connecting a 12V battery to the 12V and 0V connectors shown in Figure 2.
Once the RFX has learned the detectors it will retain the information if you
remove power.
The RFX will go into learn mode when you apply power for the first time with
the lid removed. On going into learn mode the display shows " 88 " for a few
seconds and then " -- ". You hear a short double beep.
Leaving and Returning to Learn Mode
To leave learn mode refit the RFX case lid.
Note: You MUST leave learn mode before removing power from the RFX.
To return to learn mode while power is present simply remove the RFX
case lid and press Select. The display shows " -- " when the RFX is in
learn mode.

Learning Transmitters
To make the RFX learn any transmitter:
1. If you have not already done so, put the RFX in learn mode.
2. Make sure the activity LED on the transmitter is pointing at the Learn
sensor on the RFX (see Figure 2) and no more than 100 mm away.
3. Activate the transmitter. (If necessary, activate the tamper on detec-
tors.) Make sure the light from the activity LED shines on the RFX Learn
sensor.
The RFX gives a short double beep if it successfully learns the transmit-
ter. For PAs and telecommands the display shows the total telecom-
mands learned, for example " t2 ", alternating with a digit that represents
the signal strength. For detectors the display shows the zone number on
the right, alternating with the signal strength on the left.
Note: The RFX gives a single low tone if it cannot learn the detector .
4. Repeat steps 2 and 3 for all the other transmitters you wish the RFX to
learn. Remember that the RFX can learn a total of six telecommands or
PA transmitters.
To Learn Detectors to Specific Zones
If you want to learn a detector to a specific zone, then:
1. If you have not already done so, put the RFX in learn mode.
2. Press Select until the display shows the zone number that you want.
If the display is steady then the RFX has already learned a detector for
that zone. If the display is flashing then the zone is free.
3. Make sure the activity LED of the detector is pointing at the Learn
sensor on the RFX (see Figure 2) and no more than 100mm away.
4. Activate the detector. (If necessary, activate the tamper.) Make sure the
light from the activity LED shines on the RFX Learn sensor.
The RFX gives a short double beep if it successfully learns the detector.
The display shows the zone number on the right, alternating with the
signal strength on the left.
Note: The RFX gives a single low tone if it cannot learn the detector .
4. Repeat steps 2 to 4 for all the other detectors you wish the RFX to
learn.

10 496482
Deleting Detectors
If you want to delete a single detector that the RFX has already learned:
1. If you have not already done so, put the RFX in learn mode.
2. Press Select repeatedly until the display shows the zone number of the
transmitter.
3. Press and hold Delete continuously for four seconds.
After four seconds the RFX gives a short double beep and the display
shows " -- ". The RFX has deleted the detector.
Deleting Telecommands and PA Transmitters
You cannot delete a single telecommand or PA transmitter from the RFX. To
delete one of these devices you must delete all telecommands and PAs and
then make RFX relearn the ones that you wish to keep.
1. If you have not already done so, put the RFX in learn mode.
2. Press Select until the left hand digit of the display shows a " t ".
3. Hold down Delete for four seconds.
After four seconds the RFX gives a short double beep and the display
shows " -- ". The RFX has deleted ALL telecommands and PA transmit-
ters.
Displaying the Received Signal Strength
If you want to show the signal strength from a single detector that the RFX
has already learned, then:
1. Put the RFX in learn mode, if you have not already done so.
2. Press Select until the display shows the zone number, or PA/
telecommand count.
Both the green Pass LED and the red Fail LED should be off (see
Figure 2).
3. Activate the telecommand, PA, or zone detector associated with the
number on the display.
The green Pass LED glows if the signal is strong enough, the red Fail
LED glows if the signal is too weak. The display alternates between the
zone number and the signal strength. Signal strength 2 is the minimum
acceptable strength for a reliable signal.
4. Press Select again to change the zone number and extinguish the Pass
and Fail LEDs. If you want to retest the same zone press Select until the
display shows the correct zone number.
