Signal Level - EMS FireCell Programming Manual

Signal Level; this menu allows the signal levels for selected Radio Cluster Communicator to be viewed.
When entered detailed signalling information is displayed on the two signalling channels used by the
RCC in both directions, as the devices are bi-directional. The received signal strength at the Hub from the
associated RCC is shown as a R01
the RCC to the Hub (the 01 represents the RCC number). The R01
response (30 seconds). The forward signal strength received at an RCC from the Hub is shown as a R01
Hub level, therefore indicating the signal that has been sent from the Hub to the RCC. This level is also
updated on every poll response or immediately when requested by selecting the Manual Update
Option from the menu. Turning the rotary control will change the display between the 2 channels.
Pressing the rotary control switch will revert between the R01
levels for each channel. Signal strengths are shown in dB. The levels displayed are already calculated
taking into account the background level away from the received signal strength, therefore no further
calculations are required.
Front Display Hub/RCC Options
Ch1 R01 Hub 070dB; this indicates the received signal strength at the Radio Hub from the RCC 01 on
the rst frequency channel used by the system. A level from 0 - 105 is shown to indicate the levels, a
table of which is shown at the end of this section.
Ch2 R01 Hub 070dB; this indicates the received signal strength at the Radio Hub from the RCC 01 on
the second frequency channel used by the system. A level from 0 - 105 is shown to indicate the levels, a
table of which is shown at the end of this section.
Ch1 R01 Hub 070dB; this indicates the forward signal strength received at the RCC 01 from the Radio
Hub on the rst frequency channel used by the system. A level from 0 - 105 is shown to indicate the
levels, a table of which is shown at the end of this section.
Ch2 R01 Hub 070dB; this indicates the forward signal strength received at the RCC 01 from the Radio
Hub on the second frequency channel used by the system. A level from 0 - 105 is shown to indicate the
levels, a table of which is shown at the end of this section.
