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-3500 uses Groups extensively to facilitate annunciation of multiple input and output points
on the 30 (up to 64) LED display and to facilitate the bypassing of inputs and outputs.
Display Points
The FX-3500 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 analog loop can be connected in Class B (Style 4) or Class A (Style 6 or 7) configurations.
