Conventions
Circuits
Refers to an actual electrical interface for Initiating (Detection) and Indicating (Signal) or Relays
Zone
Is a logical concept for a Fire Alarm Protected Area, and will consist of at least one Circuit.
Often the terms Zone and Circuit are used interchangeably, but in this Manual the term Circuit is used.
Events
There are events associated with every initiating, indicating and common circuit of the fire panel displayed via the
LCD.
Wiring Styles
Initiating and indicating circuits are Class B (Style B and Y). Changing the initiating circuits to Class A requires an
ICAC-306 adder board which will convert SIX initiating zones from Class B (Style B) circuits to Class A (Style D).
This is done without penalizing the number of circuits, which remains the same as in Class B (Style B). Changing
the indicating circuits to Class A requires an OCAC-304 adder board which will convert FOUR indicating zones from
Class B (Style Y) circuits to Class A (Style Z) or an OCAC-302 adder board which will convert TWO indicating zones
from Class B (Style Y) circuits to Class A (Style Z).
