  17. 734r-00 External Connections Link out Internal reed & External reed, connect sensor and tamper as shown, B channel Only1 zone used but NO Transmitter Lid tamper A + B channel 2 Zones & Transmitter Lid Tamper If Internal Reed Linked Out, Connect External Reed to these terminals Shock Sensor or Roller Shutter Sensor Max cable = 3-10 metres, Note:This transmitter is designed to use the internal reed contact + an external Sensor (shock sensor or Roller Shutter Sensor) connected to external connection “Alarm” , thus 2 Zones could be triggered simultaneously if the area was attacked

  18. 2K2 4K7 734r-01 Universal Transmitter EN50131-1: Grade 2 Tamper Alarm Note: Transmission power output of 10mW and a supervision auto reporting time interval of 4 minutes. Battery Life 20- 24 Months depending on traffic.

  19. 734r-01 Universal Transmitter EN50131-1: Grade 2 LK2. Internal Reed Fitted = Disabled Not Fitted = active LK1. LED Enable/Disable Fitted = Enabled Note: If the internal reed is used and a 2K2 resistor is fitted across the terminals the transmitter can be learned as channel “A” and thus uses 1 zone only with the transmitter Lid Tamper enabled. If the external connection is used for a contact or sensor, LK2 is fitted the transmitter Lid Tamper will not be active unless the transmitter is learned into 2 zones = A + B channels.

  20. 739r Break Glass Transmitter Invert Input jumper Link to Enable LED Aritech/Sentrol Break Glass Detector, 3V operation Note:This Detector has NO enclosure Tamper switch thus is not EN50131-1 Grade 2 Note: Transmission power output of 10mW and a supervision auto reporting time interval of 4 minutes.

  25. What Type of Radio ? • Which is the best radio for use in a an Intruder Alarm System and why ? • Both AM & FM are used for low power telemetry • AM (Amplitude Modulation), where the message code is created by varying the size or amplitude, of the radio signal. • AM was the first method chosen, as it is easier and cheaper to build. • Radio reception on the AM bands, “long and medium wave” is often prone to interference, and at night sometimes totally impossible to listen to !

  26. AM Transmission Injected Sine Wave Data Content Signal Varying Amplitude Signal

  27. Types of Radio • Why change to FM ? • To solve this problem the broadcasters switched to FM (Frequency-Modulation), where the signal size remains constant but the frequency is varied in different degrees either side of a designated frequency. • FM is less affected by interference than AM and has one other very useful feature Signal Capture !

  28. FM Transmission Injected Sine Wave Data Content Signal Varying Frequency Signal Constant Amplitude Signal

  29. Type of Radio • Signal Capture • An FM receiver will select and lock-on to the strongest signal from a number of similar signals received.It will reject signals which cannot decode. • In similar circumstances an AM receiver can become totally confused and ignore all signals.

  30. Why Use 868MHz • The European CEPT organisation have allocated a specific frequency for Short Range Devices (SRD). • The frequency band is 868 > 870MHz. • The exact frequency chosen is 868.6625 MHz. • Within that band two specific sub-bands 100KHz wide is allocated and protected for Intruder Alarm use only. • The Radio equipment operating in this band must have a bandwidth (channel spacing) of <25KHz and a duty cycle of 0.1% (3.6 seconds transmission in any one hour)

  32. Operating Range • Transmission in Free Space: • We would love to quote a maximum & minimum range, mother nature imposes certain rules that effectively means every site is different, however we will support a Tx > Rx free space (Clear line of Site - outdoors) range of “Plus 200 metres”.

  33. Attenuation • The affect of radio transmissions in a building: • Attenuation is the amount of reduction in a signal from the transmitter to the receiver, and can be caused by a wide variety of natural and man-made hazards.

  34. Attenuation • The most common form of attenuation is that caused by buildings. Some building material are more dampening then others, metallic surfaces in sufficient size can actually stop all radio signals,whilst in other situations the same amount of metal can actually increase the signal by reflection.

  35. Attenuation • Even in the worst case, careful siting of the transmitters and the receivers can often reduce the problem.

  36. 868 Radio Site Survey • The Radio Site Survey will determine the correct location of each transmitter and ensure a reliable signal to the Radio Receiver (RFX). • Fit the batteries in the test transmitter and switch on the unit, it will start to transmit every 2-3 seconds. • Locate the transmitter where you want to mount the RFX • Switch on the 790rTest Meter/receiver, ensure that the battery is ok. • Learn the test transmitter into the 790r (see instructions) • Take 790r to each required transmitter location, note reading in a range 0-9. • Minimum signal strength acceptable is 3! • Ideal received signal strength 5 > 8/9. Note: The signal strength reading is equivalent to the RFX with the Lid on =Not Attenuated.

  37. 790r Site Test Meter

  38. 868 Does & Don'ts • Do NOT site the RFX receiver • Outside the area covered by the alarm system. • Near ground level. • Do NOT site the RFX or Detectors • Close to or on large structures, for example: metal water or gas pipes. • Closer than one metre to mains wiring and metal water or gas pipes. • Next to high voltage electrical equipment, or electronic equipment. Computers - Photocopiers - other Radios.

  39. 868 Does & Don'ts • Do site the RFX • In a convenient location to connect to the control unit or a remote keypad. • Within a protected area. • Ensure that there is clear space around the RFX to allow it to receive a good quality radio signal.
