The ACK sentence used in AP5065
The Alarm Panel accepts the following sentence on the LISTENER port:
$aaACK,id*hh
• <aa> is the talker ID. This is disregarded by the Alarm Panel and may be set to any two-
letter combination.
• <id> is the alarm number ID. This is also disregarded by the Alarm Panel and may be
omitted (along with the preceding comma).
• <hh> is the checksum as previously described.
When the Alarm Panel receives such a sentence, it will forward mute requests to all the
connected systems. It is equivalent to pressing the MUTE button on the front panel.
