  • Page 26: Project Engineering

    Project engineering Project engineering When planning a project, proceed as follows: Measure the radio wave propagation (field strength measurement) in the building with a suitable radio test set. Plan the subdivision of the radio coverage area in different radio cells. This information is required to plan the number and positioning of the radio gateways.

  • Page 27: Transmission Field

    Project engineering Transmission field In free environmental conditions, the field strenght decreases by 1/r²; i.e. with double distance the attenuation increases by 6 dB. In buildings this factor is, as a first approximation, 1/r , i.e. with double distance the attenuation increases by approx.

  • Page 28

    Project engineering To determine the actual attenuation at the location of the receiver, the guide values of the construction elements along the radio transmission distance as listed in the table must be added. Construction element Additional attenuation Partition < 1 dB dry bricks approx.

  • Page 29: Defining The Place Of Installation

    Project engineering Defining the place of installation General restrictions / system limitations Maximum number of radio detectors per radio gateway Maximum distance between radio gateway and radio detector 40 m or 90 dB Several radio gateways use the same basis channel Faults or malfunctions may occur.

  • Page 30: Installation

    Installation Installation Installation and connection of the radio gateway Prerequisite The detector line must be switched off! Install the radio gateway so that it is at any time easily accessible for battery exchange and for the operation elements MC-Link connector, button and reed contact. Pay attention to a correct positioning, so that the LEDs are visible.
