A8BM-24DCR

Overview

The Moflash A8BM-24DCR is a surface-mounted marine bell from the A8BM series, operating on 24V DC with a current consumption of 400mA. It produces a single-tone sound at 108 dBA measured at 1 meter distance. The unit features an IP66 rating for dust and water resistance, suitable for harsh environments. Operating temperatures range from -25°C to 50°C. The housing is constructed from durable materials with a diameter of 219mm (8-inch gong size). It includes up to four M20 cable entry knockouts for secure wiring installation.

Feature Summary

• Produces a rich, clear traditional bell sound free from mechanical clatter
• IP66 rated enclosure ensures protection against dust and powerful water jets
• Surface mounting design with anti-tamper gong bolt mechanism
• Compliant with EN 50130-4:2011 alarm system standards

Applications

• Marine vessel signaling systems
• Industrial alarm installations requiring high durability
• Outdoor warning systems in harsh weather conditions

Procurement Notes

Verify the specific voltage requirement matches the application circuit, as this model is designated for 24V DC operation. Confirm that the 108 dBA output level meets local noise regulations for the intended installation site. Ensure mounting surfaces can support the physical dimensions and weight of the 8-inch gong assembly. Check for necessary M20 cable glands compatible with the provided knockouts.

Selection Notes

Select this model when a higher sound pressure level than the A6BM series is required. The 8-inch gong provides greater acoustic projection compared to smaller variants. Consider the 24V DC input if low-voltage safety or existing control systems dictate the power supply choice. Verify space availability for the larger 219mm diameter footprint.

Part Context

This component belongs to the Moflash A8BM series of industrial and marine bells. It shares design principles with the A6BM series but features a larger 8-inch gong for increased volume. The series is designed for robust performance in demanding environments, offering various voltage options within the same form factor.

Replacement Considerations

The A6BM-24DCR is a similar model within the same product line but features a smaller 6-inch gong and lower sound output. Direct substitution requires verifying if the reduced acoustic level is acceptable for the application.
