Product Description
DWJ-2Z Waterproof High-Power Siren For General Emergency Alarm System
Product Introduction
The Marine DWJ-2Z Waterproof High-Power Siren is an industrial-grade audible signaling device engineered to deliver exceptionally loud, penetrating, and reliable alarms in harsh maritime and offshore environments. Designed as a standalone siren or as a critical component of integrated safety systems, it is ideal for applications including General Emergency Alarms (GEA), fire alarms, toxic gas detection warnings, and muster alerts.
At the core of the DWJ-2Z is a high-efficiency acoustic mechanism capable of generating extremely high sound pressure levels (SPL), ensuring that alarms are clearly heard across vast open decks, through multiple compartments, and over background engine noise. It typically offers multiple selectable tone patterns—such as continuous wail, pulsing, or distinct coded signals—to convey different types of emergencies, thereby improving crew response and situational awareness.
Built for maximum durability, the siren features a robust, fully sealed housing constructed from corrosion-resistant materials like marine-grade aluminum alloy or reinforced composite. Its design achieves a high ingress protection rating (IP66/IP68 or higher), making it completely waterproof, dustproof, and resistant to damage from salt spray, UV exposure, and high-pressure washdowns. This allows for flexible and reliable installation in exposed outdoor locations such as masts, deckhouses, and topside structures.
The siren is designed for broad voltage compatibility (e.g., 24VDC/110VDC/220VAC), straightforward wiring, and minimal maintenance. Its solid-state construction ensures long-term performance with high resistance to vibration, shock, and temperature extremes. As a powerful and resilient audible warning device, the DWJ-2Z enhances onboard safety, supports regulatory compliance, and provides a dependable alarm signal when it matters most.
