Dual Alarm Modes for Tiered Marine Safety Response
The JIEXI Marine Sound and Light Alarm delivers high-performance visual and audible notifications designed for use in ballast water treatment and other marine safety systems. It supports two independent alarm types—early warning and fire alarm—which allow operators to distinguish the severity of onboard events. Both modes are linked to visual red light indicators and sounders to ensure high visibility and clarity, especially in noisy or visually complex marine environments. Designed for real-time response, the alarm signals are triggered by automatic detection equipment or manual activation through buttons installed at relevant positions, making it versatile for multiple alerting scenarios. Its reliability is critical in marine settings where detection and alarm delays can lead to costly or dangerous outcomes. The alarm integrates seamlessly into broader shipboard alert architectures, reinforcing multi-layered safety systems across compartments.

Independent Fault Feedback and Visual Signal Assurance
A key design feature of the JIEXI Sound and Light Alarm is its independent fault detection and feedback system. When the power supply of the bus fails or the wiring becomes disconnected, the alarm can automatically transmit a fault status signal back to the fire alarm controller. This ensures that any system-level failure is flagged immediately, avoiding blind spots in safety coverage. The LED indicators use multiple ultra-bright red lights, consuming low power while offering a long lifespan and vivid visibility in low-light conditions such as engine rooms, galleys, or enclosed control panels. The design is compact but robust, housing all components in a durable casing suited for marine corrosion and vibration resistance. These performance elements guarantee that the device continues working even under challenging environmental factors like heat, humidity, and operational wear and tear, making it ideal for deployment near pressure gauge or temperature detection instruments.

Manual Override and Signal Integrity in Critical Events
The alarm unit remains operational even when the signal bus is damaged or disconnected. A short-circuiting external control terminal allows the alarm to be activated through manual push buttons, ensuring functionality when automated signals are not available. This safeguard enhances operational security, especially in shipboard fire emergencies or component malfunctions. Signal buses and power supply connections are non-polarized, simplifying installation and reducing the risk of incorrect wiring during maintenance or emergency replacement. The alarm also provides stable start-up without interference from signal fluctuations, ensuring consistent alerting capabilities. Its manual override allows real-time testing during inspections, or immediate activation in the event of early smoke or unusual pressure gauge fluctuations, before automatic systems trigger. Altogether, the JIEXI alarm is a mission-critical tool that helps protect personnel, equipment, and vessel integrity in high-risk operational scenarios.

Product Advantages

Two-Level Alarm System with Audible and Visual Feedback
Unlike conventional alarms that provide a single trigger level, this JIEXI device includes both early warning and fire alarm functionality, enabling crew members to assess the urgency of an alert and initiate the appropriate response. Each level is supported with high-intensity sound and LED indicators, which are visible and audible across a range of marine compartments. The dual-level system ensures alerts are escalated progressively, reducing unnecessary panic while maintaining strict safety control. This tiered structure provides more situational clarity for crew and maintenance personnel, helping differentiate between operational warnings and emergency events that require full evacuation or fire suppression protocols.

Energy-Efficient LED System with Long-Range Visibility
The alarm includes a visual alert system powered by multiple ultra-bright red LEDs, capable of cutting through low-visibility conditions like fog, steam, or dark enclosed spaces. These LEDs offer high output while consuming minimal energy, making them ideal for vessels with strict power budgets. The long service life of these LEDs ensures extended usability without frequent replacement, even in high-demand applications such as continuous engine monitoring or thermocouple fire detection systems. The design is compact, minimizing installation footprint, while offering maximum visibility and audibility for alerts, making it a dependable addition to any onboard alert system.

Redundancy and Control System Integrity
One of the strongest advantages of this JIEXI unit is its signal reliability. Even in the event of a signal line failure or a dropped voltage on the power bus, the alarm remains responsive via the independent control circuit. Fault signals are automatically transmitted to the controller, ensuring no failure goes unnoticed. The non-polarized terminal design minimizes wiring errors and supports faster installation in tight deadlines. Its manual control interface acts as an emergency fallback, allowing alarms to be triggered immediately without controller activation, offering maximum flexibility in both automated and manual operations. These safeguards are vital for vessels operating in high-risk waters or harsh conditions.

Use Scenarios

Ballast Water Treatment Plant Fire Monitoring
In marine ballast systems, early detection of fire or heat abnormalities is crucial. This alarm unit integrates with thermocouple sensors or pressure monitors to trigger visual and audible alerts when predefined thresholds are exceeded. The dual-mode alarm makes it easier for crew to understand whether the issue is minor or escalated, enabling preventive intervention or emergency procedures. Since these compartments are often unmanned, the combination of visible lights and audible sound ensures maximum alert reach even from a distance.

Control Room Emergency Notification System
Installed in ship control rooms or bridge stations, the JIEXI alarm acts as a last-line visual and audible notification point, delivering rapid alerts for events such as pump overpressure, fire in ventilation ducts, or loss of power to safety-critical instruments. By distinguishing early vs. emergency alerts, it supports more intelligent response coordination among officers and crew. Its pressure gauge monitoring integration makes it especially useful for mechanical systems prone to overheating or pressure imbalance.

Manual Emergency Signal in Machinery Spaces
In high-noise areas like engine rooms or mechanical compartments, traditional alarms may go unnoticed. The JIEXI alarm’s loud audible siren combined with flashing LED lights offers maximum visibility. Furthermore, manual activation buttons allow crew to trigger alarms during abnormal manual inspections, especially when monitoring oxygen detectors, flow meters, or temperature gauges. This provides an additional layer of safety in confined spaces where sensor-based detection may be limited by location or coverage.
