M4RT1 Fireye Flame Safeguard Control

Overview

The Fireye M4RT1 Flame Safeguard Control is a compact, modular burner management system designed to provide automatic ignition and continuous flame monitoring for commercial-sized heating and process burners. It is primarily engineered for burners using gaseous fuels, ensuring safe operation through precise sequencing of the burner cycle. The system integrates a built-in amplifier and programmer, using flame rectification technology to detect the presence of a flame and safeguard against unsafe ignition conditions.

Features

• Flame rectification sensing technology for highly accurate and reliable flame detection.
• Integrated safety checking circuit that operates on every start to prevent ignition if a flame signal is present during the off-cycle or purge.
• Onboard jumpers allow for factory or field configuration of functions such as recycle/non-recycle operation and purge timing.
• LED indicator lights provide real-time operating status and diagnostic information.
• Compact design with built-in terminals, often eliminating the need for a separate wiring base.
• Automatic lockout protection that activates an alarm circuit in the event of ignition failure or safety shutdown.

Specifications

• Supply Voltage: 120 VAC (min. 102, max. 132) at 60 Hz.
• Power Consumption: 12 VA (Operating).
• Purge Time: Factory default of 5 seconds (adjustable via jumpers to 7, 30, 60, or 240 seconds).
• Pilot Trial for Ignition (PTFI): 10 seconds.
• Flame Failure Response Time (FFRT): Fixed at 3 seconds.
• Ambient Temperature Limits: -40 degrees F to 125 degrees F (-40 degrees C to 52 degrees C).
• Shipping Weight: Approximately 2.2 lbs (1.0 kg).
• Approvals: UL Recognized and FM Approved.

Applications

The M4RT1 is ideally suited for monitoring flames from gaseous fuels in commercial and industrial combustion systems. It is commonly used with Fireye 69ND1 flame rods and can be integrated into various burner configurations for natural gas or propane. While optimized for gas, it can also be used in certain light oil-fired applications. It is frequently employed in boilers, furnaces, and other process heating equipment where dependable, automatic flame supervision is required.
