401/029/3-83
The Honeywell R4343 E1006 is a flame switch designed to detect the presence or absence of a flame signal within burner control and fire alarm systems. Rated at 115V 50Hz with a contact rating of 2A 240V and a response time of less than one second, this component plays a critical role in ensuring rapid flame status confirmation. Onboard ship, flame switches of this type are integrated into boiler management, incinerator control, and fire detection circuits — forming part of the broader Fire Alarm System infrastructure. Reliable flame signal switching directly supports safe combustion management and contributes to fire safety compliance across a wide range of vessel types.
Key Features
✓ Rated supply voltage of 115V 50Hz with a 2A 240V output contact rating as specified on the nameplate, enabling integration into standard marine electrical circuits.
✓ Sub-second response time (T<1S) ensures near-immediate flame status switching, critical for safe burner shutdown or alarm activation in combustion control loops.
✓ Designed for use within Honeywell burner control and flame supervision systems; compatibility with specific panels or controllers should be confirmed against system documentation.
✓ Suitable for installation in machinery spaces and boiler rooms aboard marine vessels; installation conditions and mounting requirements should be verified against original system drawings.
✓ As a direct-replacement component within an established fire alarm or burner control system, sourcing the correct part number helps maintain system integrity and supports ongoing SOLAS-relevant fire safety obligations.
Marine Applications
✓ Boiler control systems on tankers, bulk carriers, and container vessels where continuous flame supervision is required for safe fuel combustion.
✓ Marine incinerator units fitted with automated burner management systems requiring fast-acting flame detection switching.
✓ Auxiliary heating systems on offshore support vessels and platform supply vessels where burner safety interlocks are mandatory.
✓ Fire detection and suppression control panels aboard passenger ferries and RoPax vessels requiring reliable flame signal processing.
✓ Engine room combustion monitoring circuits on naval auxiliaries and government vessels where flame switch reliability is operationally critical.
Why Marine Engineers Choose
Marine engineers specify the Honeywell R4343 E1006 because it delivers fast, reliable flame status switching with clearly defined electrical ratings, making it a dependable component in safety-critical burner control and fire alarm circuits where response time and contact reliability are non-negotiable.
Ideal For
Tankers, bulk carriers, container ships, offshore support vessels, passenger ferries, naval auxiliaries, and any commercial or industrial vessel operating boilers, incinerators, or fuel-fired heating equipment requiring flame supervision.
Technical Support & Compliance
Technical assistance is available to support troubleshooting, onboard commissioning, system integration, and retrofit or upgrade projects involving this flame switch. Guidance on wiring, compatibility verification, and replacement procedures can be provided remotely or coordinated for onboard support — all subject to confirmation of the specific system configuration. To confirm suitability and compatibility, buyers are encouraged to share nameplate photographs, existing part numbers, system model and version details, relevant wiring diagrams or drawings, vessel name, IMO number, and a clear description of the installation scope.
