Fireye MicroM Series Flame Safeguard Control System

Fireye’s MicroM series flame safeguard control is a compact, microprocessor based, modular burner management system designed to provide automatic ignition and continuous flame monitoring for commercial sizes of heating and process equipment firing any type of fuel.

Unlike other flame safeguard control systems, the MicroM is not dependent on discrete components to provide timing functions. Through its microcontroller technology, MicroM includes smart diagnostic LEDs, smart reset function for multi-burner applications, and options for a local alphanumeric display output (ED510) and serial communications via Modbus or E500 communications interface.

A complete MicroM system includes a standard chassis and wiring base, a programmer module, plug-in flame amplifier, and a flame detector. Interchangeable programmer and amplifier modules let you change control function, timing, and flame scanning as your application needs change. Type of flame scanner and the flame failure response time (FFRT) are determined by the amplifier module.

Key Specifications

  • Automatic ignition and continuous flame monitoring
  • Choose from the following functions: relight, recycle, non-recycle, two-stage capability, non-recycle air flow, proof of air flow open at start, purge timing, early spark termination, pilot proving, and cutoff
  • LED indicators show current operating status and display fault as a coded sequence during lockout
  • Compatible with flame rod (flame rectification), ultraviolet (UV) scanners, and self-checking UV scanners for continuous operation
  • Optional ED510 alphanumeric display and communication interface module
