Signal Level; Manual Update - EMS FireCell Programming Manual

Signal Level; this menu allows the signal levels for devices to be viewed. When entered detailed
signalling information is displayed on the two signalling channels used by the device in both directions,
as the devices are bi-directional. The received signal strength at the devices associated RCC is shown as
a D RCC01 level, therefore indicating the signal that has been sent from the device to the RCC (the 01
represents the RCC number). The D
forward signal strength received at a device from the RCC is shown as a D
indicating the signal that has been sent from the RCC to the device. The D
automatically every 6 hours 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 D
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.

Ch1 D RCC02; this indicates the received signal strength at the devices associated RCC (in this
example RCC number 02) from the device on the rst frequency channel used by the system. A level
from 0 - 45 is shown to indicate the levels, a table of which is shown at the end of this section.
Ch2 D RCC02; this indicates the received signal strength at the devices associated RCC (in this
example RCC number 02) from the device on the second frequency channel used by the system. A level
from 0 - 45 is shown to indicate the levels, a table of which is shown at the end of this section.
Ch1 D RCC02; this indicates the forward signal strength received at the device from the associated
RCC (in this example RCC number 02) on the rst frequency channel used by the system. A level from 0
- 45 is shown to indicate the levels, a table of which is shown at the end of this section.
Ch2 D RCC02; this indicates the forward signal strength received at the device from the associated
RCC (in this example RCC number 02) on the second frequency channel used by the system. A level from
0 - 45 is shown to indicate the levels, a table of which is shown at the end of this section.
20dB or greater
Manual Update; this menu allows individual devices to update the system with their current signal
levels. To send a signal request, press the rotary control button with the device shown on the display.
The menu will change to show that it's updating the signal level. Once completed check the new signal
level by entering the Signal Level menu.
