3.0 Conventions
3.1 Circuits
Refers to an actual electrical interface for Initiating (Detection) and Indicating (Signal or NAC)
or Relays.
3.2 Zone
Is a logical concept for a Fire Alarm Protected Area, and consists of at least one circuit.
Often the terms zone and circuit are used interchangeably, but in this manual circuit refers
only to a physical electrical loop.
3.3 Display Points
There is a display point associated with every initiating and indicating circuit of the MR-2300
LED Series fire panel. For an initiating circuit there are 2 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.
3.4 Wiring Styles
Initiating and indicating circuits are Class B (formerly style B and Y).
Changing the initiating circuits to Class A requires an MR-2300-A adder board which converts
six initiating zones from Class B circuits to Class A. This is done without decreasing the
number of circuits, which remains the same as in Class B.
Changing the indicating circuits to Class A requires an MR-2300-NC4 adder board which
converts four indicating zones from Class B circuits to Class A or an MR-2300-NC2 adder
board which converts two indicating zones from Class B circuits to Class A.
