IDNet is a Simplex protocol for addressable initiating devices, such as automatic and manual sensors, used to detect fire conditions [1].
It can be hosted on a system power supply or a dedicated IDNet option card and is programmed through the Hardware or Point tabs in the system software (Page 130) [1].
The protocol includes diagnostic capabilities to locate earth faults between specific isolators on the loop [2].
I couldn't find information regarding FlashScan or Signature in our manuals.
