Probably it examines controller's NIF or generic/specific class to determine which type of command to send.

Also not so clear to me why it sends Alarm Sensor frame, even though it claims Alarm. But again, FGK doesn't have Alarm in NIF, it only has Alarm Sensor. I suspect their tech writers just don't distinguish between those command classes.

Ok, thanks.
Do you know about 'broadcast' alarm frames?
In manual they say

Code: Select all

The frame is sent in “broadcast” mode, i.e. to all devices within range -
information sent in this mode is not repeated by the mesh network.
So If I'm right the Frame is not relayed through network, and if controller is not in direct range from sensor then it will not see the Alarm?

Yes, broadcast packets are not routed (because it could create an infinite retransmission), so they're only received by devices in range. Also delivery of broadcast packets is not reliable, because they're not confirmed with radio ACK.
