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.

Display Points

There is a display point associated with every initiating and indicating circuit of the FA-300 LED Series fire panel.
For an initiating circuit there are two LEDs for every display point: one single color (amber) and one dual color (red/
amber). For an indicating circuit there is only one LED: one single color (amber), for every display point.

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).
