Safe-T-Alert FX-4 Marine Carbon Monoxide Alarm – 2-Pack | MPN: FX-4MARINE2-PACK

Protect your passengers and crew from invisible dangers with the Safe-T-Alert FX-4 Marine Carbon Monoxide Alarm 2-Pack (Part Number: FX-4MARINE2-PACK). Engine exhaust, generator emissions, and station-wagon effect backdrafts make carbon monoxide (CO) one of the most hazardous threats on the water. Engineered specifically for marine environments, the FX-4 provides reliable, continuous CO detection inside boat cabins, sleeping berths, and wheelhouses.

This convenient 2-pack allows boater owners to outfit multiple interior spaces—such as the main salon and forward stateroom—ensuring comprehensive safety coverage throughout the vessel. Designed for direct hardwiring into your boat’s 12V DC power system, the FX-4 eliminates the risk of dead battery failures, giving you round-the-clock protection whenever your vessel's electrical system is active.

Key Features & Performance Advantages

  • Dual Alarm Value Pack: Includes two (2) complete carbon monoxide detectors for complete coverage across multiple cabins, berths, or salon areas.

  • 12V DC Hardwired Reliability: Connects directly into the vessel's 12V power supply to ensure uninterrupted protection with zero dead battery worries.

  • ABYC & UL Certified: Meets strict ANSI/UL STD 2034, ABYC A-24, and NMMA marine safety standards for recreational craft.

  • Microprocessor Intelligence: Advanced sensor filtering prevents false alarms triggered by temporary engine exhaust fumes or high ambient humidity.

  • Loud 85 dB Alarm & LED Indicators: Emits a powerful 85-decibel piercing alarm accompanied by clear visual LED status alerts (Power, Fault, Alarm).

  • Smart Mute / Test Button: Easily silences temporary alarms during testing, automatically reactivating if carbon monoxide levels remain at hazardous concentrations.

  • Low Power Draw: High-efficiency circuitry draws minimal amperage from your battery bank during standby operation.

  • Surface-Mount Compact Footprint: Low-profile design mounts directly onto bulkheads or walls without requiring large rectangular cutouts.

Frequently Asked Questions (FAQ)

Q: Why do I need a 2-pack for my boat?

A: According to ABYC marine safety guidelines, a carbon monoxide detector should be installed in every enclosed sleeping space and main living area (salon/galley) where passengers spend extended time or where generator/engine fumes could accumulate.

Q: Will these alarms drain my boat's battery when moored?

A: No, the FX-4 utilizes ultra-low current draw microprocessors designed specifically to remain connected to 12V marine battery banks without causing significant battery discharge.

Q: Can I use residential 120V or battery-operated home CO detectors on my boat?

A: No. Home CO detectors are not built to handle the constant vibration, salt spray, high humidity, or temperature extremes of a marine environment. Only marine-rated alarms meeting ABYC A-24 standards should be used aboard boats.
