Fireye Burner Logix Annunciator – YZ300
Need help selecting your product?
The Fireye YZ300 and YZ320 modules help you find burner problems faster. They work with the Fireye BurnerLogix system and show clear messages when a burner shuts down. These messages tell you which safety switch caused the problem.
Each module connects to up to 20 interlock switches. If one switch opens, the BurnerLogix screen shows the first switch that failed. This saves time and helps prevent long burner shutdowns. The modules also work when two fuels are running at the same time.
You can change the message for each switch. Use a Fireye BLV512 or BLL510 display to choose from a list of built-in messages. Or you can write your own messages using Fireye’s YZ300P software on a Windows PC. You don’t need to connect the module to a burner system to do this.
The YZ300 and YZ320 connect to Fireye YB110, YB230, ZB110, or ZB230 units. For YB models, the engineering code must be 3 or higher. The module is small—just 4 inches wide and 7 inches tall—and fits in tight panels. It has 24 screw-clamp terminals, all clearly numbered for easy wiring.
These Fireye annunciator modules make burner systems easier to troubleshoot. They help lower repair time, support dual-fuel use, and improve system safety. For more details, see Fireye Bulletins BL-1001 or BLZ-1001.
