Product details
Product Overview
The Fireye 59-546-9 is a smart 8-conductor cable assembly with an 8-pin female connector. It combines infrared and ultraviolet sensors in one rugged device. This unit delivers two flame relays, a fault relay, and two 4-20 mA outputs. It works with an intrinsically safe wireless handheld tool for easy setup. Ideal for industrial burners and boiler systems.
Key Features
- Dual-sensor technology – Infrared + UV in one housing.
- Three relay outputs – 2 flame relays (SPDT) + 1 fault relay (SPST).
- Standard 4-20 mA outputs – two isolated loops.
- Wireless commissioning – use the handheld tool without opening the panel.
- Wide ambient range – -40°F to +150°F (-40°C to +65°C).

FAQ
- What power supply do you recommend?
Fireye 60-2685 is recommended for stable 24 Vdc with hold time. - Can I use this with a dirty fuel?
Yes – increase purge air up to 15 SCFM for dusty conditions. - Is the mounting flange included?
No – order flange separately per bulletin CU-117. - How do I adjust sensitivity?
Use the wireless tool or the 4-20 mA output scaling. - What is the cable length?
9 meters (approx. 29.5 feet) with 8-pin female end. - Does it work with existing Fireye systems?
Yes – it is designed for the 59 series platform. - What if I need a longer cable?
Contact sales for custom lengths – not standard. - Is the wireless tool safe in hazardous areas?
Yes – it is intrinsically safe (IS rated).
Selection Guide
- For clean natural gas – use 4 SCFM purge air.
- For heavy oil or coal – choose 15 SCFM and high-temp flange.
- For outdoor installations – verify ambient temp range.
- For fast response – adjust relay delay via the tool.
- Always match the power supply to 24 Vdc with ≥20 ms hold.
