Frequently Asked Questions
Q What gases can this detector measure?
The detector is designed for combustible gases such as Methane and Propane, utilizing catalytic combustion or semiconductor sensors for accurate detection.
Q How does the device support calibration and adjustment without opening the casing?
It features an infrared remote control operation design, enabling full on-site setup and adjustments without needing to open the explosion-proof enclosure.
Q What communication and output interfaces are supported?
The system supports both S-BUS communication and a standard 4-20mA point-to-point output, as well as an active DC24V/30mA relay control output for sirens, fans, or valves.
Q What is the ingress and explosion-proof rating of the enclosure?
It offers an IP66 ingress protection rating and an Exdb IIC T6 Gb explosion-proof certification, making it suitable for harsh and demanding industrial environments.
Q What is the typical lifespan of the catalytic sensor?
Under normal operating conditions, the typical service lifespan of the catalytic sensor is approximately three years.
Q What are the default alarm thresholds configured on the device?
