On a panel network, information is not sent or received by any panel in access level 3 and the panels will only send and receive signals when in access level 1 or 2. When panels are networked to a BMS interface and an event comes through from the graphics system (fire, fault, disable, enable etc.), only panels in access levels 1 and 2 will receive this information.
If a panel was in access level 3 it did not receive this information, and when it came out of access level 3 into level 2, the signal was not re-sent. Therefore, even though the panel is then in access level 2, it still did not receive the event from the BMS interface.
A fix has been made so when a panel is taken out of access level 3 and put into access level 2, events from the BMS interface are re-sent, so the panel is now able to receive an update across the network to respond to the event (enable, disable, fire, fault etc.).
