RKI F-IR3-ASX5 FlameSpec Triple IR (IR3)

The RKI F-IR3-ASX5 Triple IR (IR3) Flame Detector for Hydrocarbon Fires — Standard with HART 7 & SIL 2 (High speed detection). It watches three infrared bands at once for hydrocarbon fuel and gas fires at long distance, with the highest immunity to false alarms in its triple-spectrum design. It answers a fast fire burst or explosion in 40 ms.

HART 7 digital protocol provides advanced detector communications, event push notification, and HART 7 wireless readiness, and the unit is SIL 2 rated. Outputs include a tri-colour LED, 4–20 mA, three SPST relays (fire alarm, fault, and auxiliary), and Modbus RS485 — it wires straight into your fire panel or control system.

Note: each FlameSpec head must be ordered with a mount (sold separately) — choose the standard tilt mount, the fixed high-vibration bracket, or the HD tilt mount below.
