Honeywell R7849A1023 Flame Amplifier, Minipeeper

The R7849A,B Ultraviolet Flame Amplifiers are solid state plug-in amplifiers that respond to an ultraviolet signal from a C7027, C7035 or C7044 Ultraviolet Flame Detector to indicate the presence of flame when used with 7800 SERIES and R7140 Relay Modules.

Features:

• Flame failure response time of 0.8 or 1 second; or 2.0 or 3.0 seconds, depending on the amplifier and relay module selected.
• Plug-in to 7800 SERIES and R7140 Relay Module through printed circuit board edge connector keyed for proper orientation.
• Flame signal test jacks measure amplifier flame signal voltage.
• 0.0 to 5.0 Vdc Flame signal strength reading range.
• Color coded label identifies flame detection type:
• - Green—rectification. Red—infrared.
• - Purple—ultraviolet. Blue—pulsed rectification.
• - White—optical.
• R7847B, R7848B, R7849B Dynamic Ampli-Check circuitry tests all flame amplifier components 12 times per minute. The 7800 SERIES and R7140 Relay Module locks out on safety shutdown with amplifier failure.
• R7824C, R7847C Dynamic Self-Check Rectification Amplifier, R7851C Dynamic Self-Check Optical Flame Amplifier, R7861 Self-Check Ultraviolet Flame Amplifier and R7886A Dynamic Self-Check Ultraviolet Amplifier test the detectors and all electronic components in the flame detection system 12 times per minute. The 7800 SERIES and R7140 Relay Module locks out on safety shutdown with flame detection system failure.

NOTE: R7824C, Series 2 or greater and R7847C Series 4 or greater, pulse the shutter when signal of 1.5 Vac is sensed. Display readings of 0.7 to 2.4 Vdc are common.
