FRA Tested Fast Response

Secures a critical 90-second mitigation window with rapid off-gas and faster hydrogen detection compared to legacy LEL detectors.

UL9540A Validated

Independently proven by leading BESS OEMs to deliver clear visibility of cell venting and faster hydrogen detection in unit-level testing.

Immunity to Siloxane Poisoning

Sustains accurate sensitivity levels, avoiding the severe performance drops seen in traditional catalytic sensors.

Calibration Free

Completely calibration-free with up to a 10-year lifespan for VOC (electrolyte vapors) and Hydrogen detection.

Flexible Integration

Operates via Modbus RTU over RS485 and includes 3 programmable Normally Open relay outputs.

Strict Compliance

ETL listed to UL 2075 and CSFM-5275 listed.

Cross-Zoning at Detector Level

With the latest firmware, the detector now supports detector-level Cross-Zoning for H2 (hydrogen).

Award Winning Product

Recognized globally as the Best Active Fire Safety Product Winner for its patent-pending, calibration-free detection technology.

Unlike traditional catalytic sensors, the R-GAS-FLAMMABLE is engineered to withstand exposure to siloxanes without degrading. Independent testing exposed sensors to continuous D4 and D5 siloxane vapor over 60 hours to compare performance.

Cumulative Exposure Time	R-GAS-FLAMMABLE Sensitivity	Legacy Catalytic Sensor Sensitivity
0 Hours (Pre-Test)	Consistent Output	Baseline
12 Hours	Consistent Output	-8% Sensitivity Loss
24 Hours	Consistent Output	-13% Sensitivity Loss
60 Hours	Consistent Output	-20% Sensitivity Loss

The Verdict: The R-GAS-FLAMMABLE maintained consistent baseline output with zero drift across the entire test, while the catalytic sensor suffered a cumulative 20% loss in sensitivity.
