Conventions

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. Groups are used
extensively in the FX-350 to facilitate annunciation of multiple input and output points on the 32 (up to 64) LED
display and to facilitate bypassing of inputs and outputs.

Display Points

The FX-350 provides an LCD display to annunciate the status of the system and connected devices. The FX-351
and FX-353 also provides up to 64 LED display points on the panel front in addition to the LCD display. Display
points may be assigned to LEDs during configuration to groups of inputs or outputs. There are two LEDs for every
display point: one single color (amber) and one dual color (red/amber).

Wiring Styles

The analog loop can be connected in Class B (Style Y) or Class A (Style D) configurations. 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). This is done without reducing the number of circuits.
Note: The Model FX-350-60-R and FX-350-60DR panels DO NOT recognize any devices with addresses
higher than 60.
