10.0 - VERIFY TABLE
Verify and Signal Strengths
1.Main Menu>>5.Verify Table
The verify information is essential to the engineer to ensure the system is set-up correctly. It details signal
strengths and performance information about all of the devices on the system. Each device regularly sends out
verify messages to the main panel. If these messages are not received, a verify fault message will be displayed on
the panel after a pre-programmed period of time. Although the system may appear to be working when tested, if
the signal strength is not adequate any devices with weak signal strengths are likely to fail over a period of time.
EN54 requires that the RSSI level for each device is a minimum of +10 (on a scale from -20 to +20). Devices with a
negative RSSI may not operate reliably and will need resolving.

From the ‘Verify Table’ menu, select ‘1-View Table’. Select ‘1-View Summary’. Using the and keys select number
of the device you wish to view details of.
RSSI Received Signal Strength Indicator. This is an indication of the signal strength for a
device and provides a simple ‘OK/LOW’ indication.
Count The time in seconds since the device last transmitted. The count will increment
every 5 seconds. A device transmits a verify message back to the control panel
approximately every 60 seconds.
Max Count The maximum time in seconds between two successful transmissions, received
from the device. This gives a good indication of how the device is performing. As
a device transmits every 60 seconds, if the value is around 60, it has never missed a
transmission, but if it is at 180 then two transmissions have been missed.
Pressing will display further information about the selected device.
Logged Indicates that the device has been logged on to the system.
Local Shows whether the device is assigned to communicate with this particular panel.
