Appendix A.6. Acknowledging Alarms This driver can be used to acknowledge alarms, reset or silence the Cheetah panel.
This functionality is limited. For this function to operate the Cheetah panel must be
configured to supervise the port that the FieldServer is connected to. In addition to enabling
this function, port supervision means that the panel will go into alarm if the FieldServer does
not respond to the supervision messages. In fact the request to ack /reset/ silence the panel
is included in the driver’s response to the supervision poll from the panel. The panel ignores
unsolicited messages. A consequence of this is that the driver cannot control the timing of
when the ack /reset/ silence message is sent to the panel.
In using this functionality you should also understand that the Cheetah panel protocol does
not acknowledge message receipt so this driver cannot report whether the message was
received by the panel and whether it was acted on.
The port supervision response message is sent even if you do not define a Port Response
Map Descriptor in the CSV file. In this case the command data will always be zero. Once
you define a Map Descriptor then the driver uses one Data Array element to determine the
command data to send to the panel. The value from this array element determines the
action the panel will take.
Bit
Action Decimal Value
0 Reset 1
1 Silence 2
2 Acknowledge
4
Example: If you wish to Silence the Panel, then set the value of the Data Array element to 2.
The driver supports older versions of panel firmware which transmit a shorter version of the
Panel Status command. This shorter version contains only panel data whereas the newer
version contains panel, zone & device data.
