One or both bits may be set (for a broadcast message). AlarmDecoder may not filter out messages sent to other addresses, which is only a concern in environments with multiple AUI’s. The examples used herein specify address 1.

used by the controller (binary data).

Queried many times while in programming mode by an AUI. Example:

 0060 620245 43f531fb 43 6c

Returns data very similar to the asynchronous notification:

 0e020000000050 fefe ec 01010101

Asynchronous comparison:

 160600000000 60 630245 43f531fb 45 6c f5ec01010101

The ASCII 1 parameter has no known purpose and does not appear to be related to the partition. When sent during Programming Mode the message returns a different status:

 0b040000000050 fefe ec 05

This sub-type requires a password. These commands do not function outside of an AUI scenario. There is likely some initialization sequence which is not being correctly followed (single character messages can be substituted). The first parameter contains a hex encoded ASCII password (1234), and the second parameter specifies the operation, in this example ARM STAY.

Example:

 00606203 88 ec 31323334 fb 456c f5 ec 010201010101

Returns an apparent status:

 0d020000000050 fefe ec 010001

Arm Message Format:

 00606203 88 ec P..P fb 456c f5 ec 010A0W010I01

Disarm Message Format:

 00606203 88 ec P..P fb 456c f5 ec 010101

Chime Mode Message:

 00606203 88 ec p..p fb 456c f5 ec 010C0F01

Unknown messages sent by an AUI.

Unknown 1
Sent periodically, even during Programming Mode. The first message sent by an AUI during startup.

Example:

 00606b02 4343

Returns:

 0e020000000050 fe ec 0201010000 (Programming Mode)
 0e020000000050 fe ec 0101010000 (Immediately after booting)
 0e020000000050 fe ec 01017f0000 (Normal return)

Used to query log entries.

Query Log Entry Count
Query the count of log entries using parameters.

Example:

 00606b09 4549 f5 A..A fb454a f5 B..B fb 4361

Returns:

 0d020000000050 fefefe 313030

Returns the number of entries in the log as a hex encoded ASCII value, in this example 100. Other parameters return different numbers. Using 1 or 2 for the first value appear to be valid, and using up to 14 - 24 appear to be valid for the second value. Reading logs does not function outside of an AUI device, likely due to incorrect initialization. Using the ASCII keypad method to retrieve entries after querying the total count does function.

Query Log Entry
Query a specific log entry using parameters.

Example:

 00606b09 4549 f5 A..A fb 454a f5 B..B fb 4543f5 N..N fb 436c

Returns:

 26020000000050 fefefefe ec 50302030312f30312030323a3330414d2045333032205a303030

Returns the hex encoded ASCII log entry, “P0 01/01 02:30AM E302 Z000” in this example. Note that querying log entries does not currently work.
