2.2 General Notes
Circuits
Refers to a physical electrical interface for the analog loop, indicating signals or relays, and
common alarm, supervisory, and trouble relay outputs.
Zone/Group
Is a logical concept for a Fire Alarm Protected Area, and will consist of at least one Circuit. The
FX-401 uses Groups extensively to facilitate annunciation of multiple input and output points
on the RAX-1048TZDS (up to 96 points) and to facilitate the indication of bypass points.
Display Points
The FX-401 LCD display annunciates the status of the system and connected devices. There
are up to two (2) RAX-1048TZDS Display Adder Module Display points that may be configured
to assign LEDs to groups of inputs or outputs. There are two LEDs for every display point; one
single color (yellow) and one dual color (red/yellow).
Wiring Styles
The addressable (SLC) loops can be configured system-wide as Class B (DCLB) or Class A
(DCLA). With the addition of isolators, a Class A (DCLA) loop will become a Class X (DCLC).
