Outdoor Dual Circuit Marine Telephone JWAT304
The JWAT304 intrinsically safe marine telephone is a high-performance, reliable explosion-proof communication terminal. Developed with advanced electronic and digital noise reduction technology, it leverages our company’s extensive experience in industrial scheduling communication systems. This device connects seamlessly to various existing switches or scheduling hosts, creating a robust explosion-proof communication system ideal for marine environments.
Purpose-built for ships, offshore platforms, and coastal facilities, this marine telephone delivers reliable, fail-safe communication in the harshest sea conditions. It is a standard analogue phone (supporting pulse and tone dialing) that combines marine-grade durability with advanced system redundancy.
- Marine-Grade Durability: Rated IP65 weatherproof, the high-strength engineering plastic housing and waterproof keypad resist moisture, corrosion, and rough handling on open decks.
- Clear Audio in Noisy Zones: Designed for loud engine rooms, it features a powerful 85+ dB(A) ringer and a heavy-duty handset with a noise-canceling microphone to ensure voices are heard clearly.
- Fail-Safe Reliability: Equipped with dual-circuit protection and line fault tolerance. The phone continues working even if minor cable breaks or short circuits occur, and automatically reports faults to the ship’s dispatch system for quick repair.
- Simple Bulkhead Installation: The wall-mounted design uses secure RJ11 screw-terminals that withstand vessel vibrations. It is entirely line-powered, requiring no external power supply.
- Maintenance & Compliance: Fully certified to CE, FCC, RoHS, and ISO9001 standards. Supported by in-house manufactured spare parts for fast fleet maintenance, and available in custom colors to meet maritime safety codes.
