  • Explosion Proof Bells and Horns for Notification and Alerting

    Stay Safe with Emergency Notification Systems 

    Explosion proof bells and horns are specialized audible signaling devices designed for use in potentially hazardous environments where there is a risk of explosion. These devices are built to withstand and contain any sparks or arcs that could ignite flammable substances or gases present in the surrounding atmosphere. If you are looking for Explosion Proof  devices for use in potentially explosive environments and suitable for use around all gas groups this article can help you.

    Here are some key features and considerations regarding explosion-proof bells and horns:

    1. Construction: Explosion Proof Bells and Horns are typically constructed with robust materials such as cast aluminum or stainless steel to ensure durability and resistance to corrosion. They are engineered to prevent the release of electrical energy that could trigger an explosion.
    2. Certification: These devices undergo rigorous testing and certification processes to meet industry standards and safety regulations. In the United States, the Underwriters Laboratories (UL) certification, particularly the UL 1203 standard, is commonly used to assess explosion-proof equipment.
    3. Sealing: Explosion-proof bells and horns employ sealing techniques, such as o-rings or gaskets, to prevent the entry of flammable substances into the device. This helps to minimize the risk of an explosion by containing any potential ignition sources.
    4. Spark-free operation: Special measures are taken to ensure that these devices do not generate sparks or arcs during operation. They may incorporate intrinsically safe circuitry or use sealed contacts to eliminate any potential sources of ignition.
    5. Audibility: Explosion-proof bells and horns are designed to produce loud and distinct sounds to alert individuals in hazardous areas. They are available in various sound output levels and tones to suit different environments and applications.
    6. Environmental ratings: These devices often carry specific environmental ratings to indicate their suitability for different hazardous locations. Common ratings include Class I, Division 1 or 2 (for flammable gases and vapors) and Class II, Division 1 or 2 (for combustible dust).
    7. Integration with control systems: Explosion-proof bells and horns can be integrated into safety control systems, enabling them to be activated in response to specific events or as part of an overall emergency warning system.

    When considering the use of explosion-proof bells and horns, it is crucial to consult relevant safety standards and regulations in your jurisdiction and involve experts familiar with hazardous area classification and electrical systems to ensure proper installation and compliance with safety requirements.

  • Horn Strobes for Fire Alarms and Emergency Notification


    For Audio and Visual Fire Alarm and Notification

    Horn Strobes are a type of audible and visual signaling device commonly used in fire alarm systems and emergency notification systems. They combine both a loud audible sound (generated by a horn or speaker) and a bright visual strobe light to effectively alert people in a building or area of an emergency situation.

    Here are some key features and characteristics of horn strobes:

    1. Audible Alarm: The horn strobe produces a loud sound, typically in the range of 85 to 120 decibels, to ensure that the alarm can be heard over ambient noise levels. The sound is often a Continuous Horn or Temporal sound designed to grab attention and indicate the need for evacuation or response.
    2. Visual Alert: In addition to the audible alarm, horn strobes incorporate a high-intensity strobe light. The strobe light emits bright flashes of light or candela setting, usually in a synchronized pattern, to provide a visual alert. Field Selectable Candela settings include15/30/75/110cd or 135/185cd (Multi-Candela models) or 1575cd (single candela model) and Ceiling Mount 15/30/75/95cd or 115/177cd The combination of sound and visual signals helps ensure that individuals with hearing impairments or those in noisy environments can be alerted.
    3. Integration with Fire Alarm Systems: Horn strobes are typically integrated into fire alarm systems and are activated when a fire alarm is triggered. Usually 24V or less common are 12V devices. They are often installed on walls or ceilings in strategic locations throughout a building to provide comprehensive coverage.
    4. Different Output Settings: Horn strobes can often be configured with different output settings to accommodate various environments. This includes adjustable volume control for the audible alarm and adjustable intensity for the strobe light.
    5. Code Compliance: Horn strobes must comply with local fire codes and regulations, which often specify requirements such as sound output, strobe intensity, placement, and visual signaling standards.
    6. Variations: There are different types of horn strobes available to suit different applications. Some models are weatherproof and suitable for outdoor use, while others are designed for indoor environments. Variations also exist in terms of the design, color, and size of the strobe housing.

    Horn strobes play a crucial role in alerting and warning individuals during emergencies, allowing for timely and orderly evacuation or response. They are commonly found in commercial buildings, industrial facilities, educational institutions, healthcare facilities, and other public spaces where fire alarm systems are required. We carry major brands Including Wheelock, System Sensor and Federal Signal.
