BBJ-2 Explosion-proof Audible And Visual Alarm Unit

Product Introduction

The Marine Explosion-Proof Audible & Visual Alarm is a high-integrity, intrinsically safe signaling device designed for use in hazardous or potentially explosive atmospheres onboard vessels and offshore installations. Engineered to meet stringent international safety standards, this dual-function alarm provides simultaneous, powerful audible and visual warnings to alert personnel to emergency situations such as gas leaks, fire, or machinery malfunctions in zones where flammable gases, vapors, or dust may be present.

Constructed with a rugged, certified explosion-proof enclosure—typically made of corrosion-resistant copper-free aluminum, stainless steel, or reinforced polymer—the device prevents internal sparks or high temperatures from igniting the surrounding atmosphere. The housing is fully sealed and designed to withstand internal explosions without allowing flames or heat to propagate externally, ensuring operational safety in critical areas like fuel pump rooms, cargo tank decks, paint lockers, and engine rooms.

The alarm integrates a high-decibel electronic siren or horn with a bright, multi-LED strobe beacon, providing clear and attention-commanding signals even in high-noise or low-visibility conditions. It often features selectable sound patterns (e.g., continuous, wailing, or pulsed tones) and flashing light modes to differentiate between types of alerts. Designed for durability in harsh marine environments, it offers high ingress protection (IP66/IP67 or higher) against water, dust, and salt spray.

Certified to international standards such as ATEX, IECEx, or specific marine hazardous area classifications, this explosion-proof alarm is essential for ensuring crew safety, regulatory compliance, and reliable emergency communication in high-risk zones onboard.
