Signal Level - EMS FIRECELL Programming Manual

RCC Ch2 RFI Det– this description indicates that a radio frequency interference signal has been
detected on radio channel 2 that the RCC network communication path is operating on.
DEV Ch1 RFI Det – this description indicates that a radio frequency interference signal has been
detected on radio channel 1 that the radio device to RCC communication path is operating on.
DEV Ch2 RFI Det– this description indicates that a radio frequency interference signal has been
detected on radio channel 2 that the radio device to RCC communication path is operating on.
Un-Assigned – this description indicates that the device is un-assigned to the system. Assigning
the device is possible by pressing the rotary control to assign or visiting the previously detailed
'Assign Devices' option from the main menu.

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
been sent from the RCC to the Hub (the 01 represents the RCC number). The R01
updated on every poll response (30 seconds). The forward signal strength received at an RCC
from the Hub is shown as a R01
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 Hub level display and R01
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
1
Ch R01 Hub 070dB – this indicates the received signal strength at the Radio Hub from the
RCC 01 on the first 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.
2
Ch 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.
1
Ch R01Hub 070dB – this indicates the forward signal strength received at the RCC 01 from
the Radio Hub on the first 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.
2
Ch R01Hub 070dB – this indicates the forward signal strength received at the RCC 01 from
