Intrinsically Safe Certification & Hazardous Locations

The HX400IS, along with its intrinsically safe battery pack (FNB-115LIIS) and optional intrinsically safe speaker microphones (SSM-14A and CMP460), is certified to ANSI/UL 913-5th Edition standards. This certification is mandatory for use in hazardous environments where explosive atmospheres may be present. Approved applications include chemical tankers, LNG/LPG carriers, oil and gas platforms, petroleum refineries, chemical processing facilities, grain elevators, coal terminals, flour mills, and any location where flammable gases, combustible dusts, or ignitable fibers create potential explosion hazards. The T3 temperature code ensures the radio's surface temperature will not exceed 200°C, preventing ignition of surrounding hazardous materials.

Land Mobile Radio Capability

The HX400IS's 40 programmable land mobile channels (134-174 MHz) make it uniquely versatile for commercial operations requiring both marine and shore-based communications. Tanker operations, port facilities, terminals, refineries with marine access, and chemical facilities benefit from a single intrinsically safe radio that handles marine VHF and land mobile frequencies. Programming includes CTCSS (Continuous Tone-Coded Squelch System) and DCS (Digital-Coded Squelch) for private channel operation within groups. Note: Land mobile frequencies require appropriate FCC licensing. Contact an authorized Standard Horizon dealer for programming services.

Secure Communications

The built-in 4-code voice scrambler provides private communications for sensitive commercial operations, security personnel, or any situation requiring confidential voice transmission. Compatible with other Standard Horizon VHF radios equipped with scrambler capability, ensuring secure communication across your commercial fleet or organization without additional equipment purchases.

Compatibility

The HX400IS is compatible with Standard Horizon intrinsically safe optional speaker microphones SSM-14A (submersible) and CMP460 (submersible), both certified to ANSI/UL913 standards for use in hazardous locations. The radio uses a CAT460 antenna (included) and accepts compatible Standard Horizon replacement antennas. Compatible with all Standard Horizon scrambler-equipped VHF radios for secure communications. Programmable land mobile channels require FCC licensing and professional programming through authorized dealers.
