Each device analyses the format and timing it receives and establishes an indicator of the signal loop line
quality. The panel updates the display as it polls each device and shows the highest (maximum) value received
and indicates this against the device number.
The value for a specific device can be shown on the bottom line. Use the

buttons to select the device
number and the value will be shown to the right.
A line is considered normal and within timing specification if the maximum value falls within the range 32
– 96.
Line quality can be affected by a number of factors. However, should higher values be shown, check the
integrity of the wiring and that the shield is continuous around the loop and not connected to any other earth
point other than at the panel. If the quality figure reported is 192 or higher then the line quality could affect
performance of the devices.
