FLAME SAFEGUARD CONTROLS

WARNING: Selection of this control for a particular application should be made by a com-
petent professional, licensed by a state or other government agency. Inappropriate application
of this product could result in an unsafe condition hazardous to life and property.

DESCRIPTION

The Fireye® M4RT1 Flame Safeguard Control is a compact burner management system. It is
designed to provide automatic ignition and continuous flame monitoring for commercial sizes of
heating and process burners that use gaseous fuels.

Flame monitoring is accomplished by a Flame Rod detector, the built in amplifier and programmer.
Control functions and timing are factory set with onboard jumpers. Functions such as recycle/non-
recycle, purge timing, and pilot trial for ignition (P.T.F.I.) time are determined by the jumpers. Flame
Failure Response Time (F.F.R.T.) is fixed at three seconds. LED indicator lights indicate the operat-
ing status of the control.

In the event of ignition failure, or following a safety shutdown, the unit locks out, activating an
alarm circuit. Cycling the power OFF and back on will reset the control. A manual reset option can
be special ordered. Remote reset (via remote pushbutton) is also available as a special order option.
A detailed description of the programmer sequence is found later in this document. Test jacks are
provided to permit flame signal measurement during operation. 

The M4RT1 control incorporates a safety checking circuit that is operative on each start. If flame
(real or simulated) is detected prior to a start or during the purge, the fuel valves will not be ener-
gized, and the unit will lock out.

All M4RT1 controls do not require a wiring base due to the terminals included on the relay board.
See INSTALLATION OF CONTROL, SCANNERS, AND FLAME DETECTORS (page 2) for tem-
perature and wiring requirements.
