Definitions:

Zone – Defines Sensor Input & Relay / Alarm Output

Group – Set of Sensors of the same type and output within the same zone

Average – Activation based upon an average of sensors in a group

Voting – Number of sensors needed to be above trip point to activate the output

Quorum – Number of sensors need to vote, 1 = any sensor
