Devices polled in blocks of 10
Each device responds with true digital signal.
CLIP only devices will give invalid reply in Flash Mode
FlashScan is an algorithm that greatly enhances the speed of communication between the
Analog intelligent devices. If one of the devices within a single group has new information,
The panel CPU stops the group poll and concentrates on single points. The net effect is a
response speed greater than five times that of earlier designs.
