RFXAll the transmitters designed to work with the RFX have an approximatemaximum range of between 100m to 200m in free space. You must takecare when siting these devices. In some circumstances you may experiencea reduction in signal strength to the receiver. This reduction is calledattenuation and can be caused by a wide variety of natural and man-madehazards.The most common form of attenuation is that caused by buildings. Somebuilding materials are more attenuating than others. Metallic surfaces of theright size can stop all radio signals by refl ecting them away from the receiver.(This also means that sometimes the same surfaces can increase the signalstrength by refl ecting more signal towards the receiver.) Wooden surfacesare almost transparent to radio signals. Brick and stone have attenuationssomewhere between metal and wood. Always carry out a site survey beforestarting installation (see below).All the transmitters, apart from the 722r/723r/727r/728r telecommands and710r/726r PAs, report every 30 minutes to the RFX. If any transmitter failsto report within two hours then the control unit generates an alarm at thekeypads and at the Alarm Receiving Centre (ARC). Do not remove any radiodetector from its area without fi rst deleting its zone number from the controlunit.Radio Site SurveyWith a wirefree system we recommend that you carry out radio tests as partof a site survey to ensure that the RFX can receive a good radio signal fromthe detectors. If you cannot do the tests during a survey, carry them outbefore installation.You will need a 790r test meter and a 734rEUR-01 test transmitter. See 790rRadio Strength Monitor User Guide for full instructions on how to use the testmeter and transmitter.1. Fit the battery into the test transmitter then fit LK1. Place the transmitterat the proposed site for the RFX. The transmitter sends out a test messageevery fi ve seconds. Note: the transmitter shuts itself down after 20minutes. To restart, remove and then refi t the battery.2. Switch the test meter ON (right hand knob). Turn the left hand knob toSingle.4 of 10The top LED (9) fl ashes rapidly, indicating that the unit needs to learn anew Transmitter Code.3. Hold the Test Transmitter so that light from its Activity LED can shine onthe Learn Sensor on the Radio Strength Monitor.4. Activate the Transmitter. (Press and release the Tamper bar at the backof the Transmitter.)
