5    Duty Cycle Correction Factor


    5.1 Test Procedure
ANSI C63.10: 2013 Section 7.5 was followed for measuring the duty cycle and calculating the duty cycle
correction factor. When necessary the duty cycle correction factor was used to compute the average
value of pulsed emissions during the radiated testing.

Beacon DCCF = 20log (4.86 / 100) = -26.26dB

Max Duty Cycle Correction factor is -20 dB.


Note: Firmware changes were made after the original testing to reduce the total transmission time. These
changes are detailed in the operational description document. These changes impact the ping mode Duty
Cycle Correction Factor, which is calculated by the manufacturer in the
“OperationalDescription_Pages4&5_2019_04-09.pdf” as -18.85dB.

6     Transmission Timing

§ 15.231(a):
      The provisions of this section are restricted to periodic operation within the band 40.66-40.70 MHz
and above 70 MHz. Except as shown in paragraph (e) of this section, the intentional radiator is restricted
to the transmission of a control signal such as those used with alarm systems, door openers, remote
switches, etc. Continuous transmissions, voice, video and the radio control of toys are not permitted. Data
is permitted to be sent with a control signal. The following conditions shall be met to comply with the
provisions for this periodic operation:

     (1) A manually operated transmitter shall employ a switch that will automatically deactivate the
transmitter within not more than 5 seconds of being released.

      (2) A transmitter activated automatically shall cease transmission within 5 seconds after activation.

     (3) Periodic transmissions at regular predetermined intervals are not permitted. However, polling or
supervision transmissions, including data, to determine system integrity of transmitters used in security or
safety applications are allowed if the total duration of transmissions does not exceed more than two
seconds per hour for each transmitter. There is no limit on the number of individual transmissions,
provided the total transmission time does not exceed two seconds per hour.

       (4) Intentional radiators which are employed for radio control purposes during emergencies involving
fire, security, and safety of life, when activated to signal an alarm, may operate during the pendency of the
alarm condition

      (5) Transmission of set-up information for security systems may exceed the transmission duration
limits in paragraphs (a)(1) and (a)(2) of this section, provided such transmissions are under the control of
a professional installer and do not exceed ten seconds after a manually operated switch is released or a
transmitter is activated automatically. Such set-up information may include data.

7    Occupied Bandwidth

    7.1 Test Limits

§ 15.231(c): The bandwidth of the emission shall be no wider than 0.25% of the center frequency for
             devices operating above 70 MHz and below 900 MHz. For devices operating above 900
             MHz, the emission shall be no wider than 0.5% of the center frequency. Bandwidth is
             determined at the points 20 dB down from the modulated carrier.

8    Radiated Spurious Emissions (Transmitter)

    8.1 Test Limits

§ 15.231(a): The provisions of this section are restricted to periodic operation within the band 40.66-40.70
             MHz and above 70 MHz. Except as shown in paragraph (e) of this section, the intentional
             radiator is restricted to the transmission of a control signal such as those used with alarm
             systems, door openers, remote switches, etc. Continuous transmissions, voice, video and
             the radio control of toys are not permitted. Data is permitted to be sent with a control signal.
             The following conditions shall be met to comply with the provisions for this periodic operation

                  (2) A transmitter activated automatically shall cease transmission within 5 seconds after
                  activation.

                  (4) Intentional radiators which are employed for radio control purposes during emergencies
                  involving fire, security, and safety of life, when activated to signal an alarm, may operate
                  during the pendency of the alarm condition.

                  (b) In addition to the provisions of §15.205, the field strength of emissions from intentional
                  radiators operated under this section shall not exceed the following:



      Fundamental                     Field strength of fundamental        Field strength of spurious emissions

         Linear interpolations.

                  (1) The above field strength limits are specified at a distance of 3 meters. The tighter limits
                       apply at the band edges.

                  (2) Intentional radiators operating under the provisions of this section shall demonstrate
                       compliance with the limits on the field strength of emissions, as shown in the above
                       table, based on the average value of the measured emissions. As an alternative,
                       compliance with the limits in the above table may be based on the use of measurement
                       instrumentation with a CISPR quasi-peak detector. The specific method of measurement
                       employed shall be specified in the application for equipment authorization. If average
                       emission measurements are employed, the provisions in §15.35 for averaging pulsed
                       emissions and for limiting peak emissions apply. Further, compliance with the provisions
                       of §15.205 shall be demonstrated using the measurement instrumentation specified in
                       that section.

                  (3) The limits on the field strength of the spurious emissions in the above table are based on
                  the fundamental frequency of the intentional radiator. Spurious emissions shall be attenuated
                  to the average (or, alternatively, CISPR quasi-peak) limits shown in this table or to the
                  general limits shown in §15.209, whichever limit permits a higher field strength.

   8.2 Test Procedure

ANSI C63.10: 2013


   8.3 Example of Field Strength Calculation Method:
The measured field strength was calculated by summing the readings taken from the spectrum analyzer
with the appropriate correction factors associated with the antenna losses and cable losses. The
calculation formula and sample calculations are listed below:

Formula:
FS = RA + AF + CF + DCCF
       FS = Field Strength in dBV/m
       RA = Receiver Amplitude in dBV
       AF = Antenna Factor in dB
       CF = Cable Attenuation Factor in dB (Including preamplifier and filter attenuation)
       DCCF = Duty Cycle Correction Factor (used for average measurements only)
       DCCF = 20*log(Time on/100mS)

Example Calculation:
      RA = 19.48 dBV
      AF = 18.52 dB
      CF = 0.78 dB
      DCCF = -20 dB

FS = 19.48 + 18.52 + 0.78 -20 = 18.78 dBV/m

   8.5 Results:
All fundamental and spurious emissions not falling into the restricted bands met the limits outlined in FCC
Part 15.231(b). Additionally, all emissions falling within restricted bands of operation were found to be
below the limit specified in Part 15.209(a). The emissions listed in the following tables are the worst case
emissions and were investigated with the sample positioned in three orthogonal axis in order to report the
highest possible field strength.

9    Antenna Requirement per FCC Part 15.203

    9.1 Test Limits

§ 15.203:    An intentional radiator shall be designed to ensure that no antenna other than that furnished by the
             responsible party shall be used with the device. The use of a permanently attached antenna or of an
             antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply
             with the provisions of this section. The manufacturer may design the unit so that a broken antenna
             can be replaced by the user, but the use of a standard antenna jack or electrical connector is
             prohibited. This requirement does not apply to carrier current devices or to devices operated under the
             provisions of §15.211, §15.213, §15.217, §15.219, or §15.221. Further, this requirement does not
             apply to intentional radiators that must be professionally installed, such as perimeter protection
             systems and some field disturbance sensors, or to other intentional radiators which, in accordance
             with §15.31(d), must be measured at the installation site. However, the installer shall be responsible
             for ensuring that the proper antenna is employed so that the limits in this part are not exceeded.


    9.2 Results:

The sample tested met the antenna requirement. The antenna used was permanently attached to the
PCB.

10   Measurement Uncertainty

The measured value related to the corresponding limit will be used to decide whether the equipment
meets the requirements.

The measurement uncertainty figures were calculated and correspond to a coverage factor of k = 2,
providing a confidence level of respectively 95.45 % in the case where the distributions characterizing the
actual measurement uncertainties are normal (Gaussian).
