Description
Overview: Microprocessor-based integrated flame switch for detecting a flame using rectification, ultraviolet (UV) or infrared (IR) source. Provides level of safety, functional capability and features beyond conventional controls.
Features:
- Can be fitted with any 7800 Series Amplifier to provide relay action from two single pole, double throw (SPDT) relays when flame is present or not present. RM7823A and EC7823 are a flame detector relays only.
- Suitable primary control must be use to provide safe-start check, safety lockout, load switching and other functions required in flame safeguard systems.
- Three LEDs to indicate power, flame and alarm.
- Access for external electrical voltage checks.
- Nonvolatile memory.
- Shutter drive output.
- Compatible with existing Honeywell flame detectors.
The Honeywell RM7823A1016 is a microprocessor-based flame detector relay designed for use in industrial and commercial flame safeguard systems. Part of Honeywell's 7800 Series, this relay module detects flame using rectification, ultraviolet (UV), or infrared (IR) sources and outputs two single pole, double throw (SPDT) relay signals based on flame presence or absence.
This unit is a flame detector relay only — it is intended to be paired with a compatible primary control that handles safe-start checks, safety lockout, load switching, and other required flame safeguard functions. It must also be used with a Q7800A or Q7800B Universal Wiring Subbase and one of the compatible 7800 Series amplifiers (R7847, R7848, R7849, R7851, R7852, R7861, or R7886).
Key Features
- Dual SPDT outputs — two relay outputs activate in response to flame detection
- 7800 Series amplifier compatible — works with any standard 7800 Series flame signal amplifier
- Three status LEDs — indicates power, flame, and alarm states for fast on-site diagnostics
- Nonvolatile memory — retains settings through power cycles
- Shutter drive output — supports shutter-equipped flame detectors
- External voltage access points — simplifies maintenance and troubleshooting
- Compatible with existing Honeywell flame detectors — easy integration into current systems

Common Applications
The RM7823A1016 is commonly used in industrial boilers, commercial heating systems, process burners, and other combustion equipment requiring reliable flame detection and relay output. It is suitable for any application where a flame switch with dual SPDT outputs is required as part of a broader flame safeguard control system.
Important Notes
- This is a flame relay only — a suitable primary burner control is required for safe-start, lockout, and load switching functions
- Not weather-tight — when installed outdoors, unit must be protected by an approved weatherproof enclosure
- Power off before wiring; follow all Honeywell and UL/CSA installation guidelines
