Product Details

The Fireye YZ320 is a 230 VAC interlock annunciator expansion module designed exclusively for the Fireye BurnerLogix burner management system, the higher‑voltage counterpart to the 120 V YZ300. This interlock annunciator module connects to ZB and YB series BurnerLogix chassis via ED580 communication cable, adding expanded limit-switch monitoring and first‑out lockout annunciation capacity. As a reliable first-out alarm expansion board, it supports 4 recycling interlock inputs and 16 non‑recycling interlock inputs; custom fault messages can be configured either through BLV512 / BLL510 local displays or the YZ300P programming software. This Fireye BurnerLogix annunciator is stocked as genuine replacement spare part, widely used on boilers, process heaters and dual‑fuel combustion systems to reduce troubleshooting time when safety interlocks trigger shutdown.

Supported Functions

This interlock annunciator module continuously monitors auxiliary safety limit switches wired to its terminal bank. The first-out alarm expansion board captures the very first interlock that trips before lockout and sends a descriptive text message to the BurnerLogix display, so technicians can identify root causes rapidly. This Fireye BurnerLogix annunciator also provides dedicated fuel selection logic for dual‑fuel setups and retains configurable alarm labels for each input terminal.

Core Functions

The first‑out capture function eliminates guesswork among multiple safety limits and shortens boiler downtime during service calls. The interlock annunciator module integrates seamlessly with existing BurnerLogix safety sequencing without modifying the core flame safeguard logic. Its terminal design supports jumper configuration for unused interlock points and single‑fuel or dual‑fuel mode selection. Standard communication protocol enables drop‑in substitution for a faulty YZ320 with matching host chassis and cable assembly.
