AKW Red Fire Alarm Bell, 6 Inch 120V AC
The AKW 6-inch fire alarm bell operates on 120V AC, a common specification for building-wide signaling systems. It is UL-listed, providing a standard of safety and reliability for public facilities such as schools and hotels. Back boxes are sold separately, enabling flexible mounting options on walls or cabinet enclosures. The device is frequently used as a school bell or alert signal, where a clear, attention-grabbing tone is needed. The compact 6-inch size supports retrofit projects or smaller outdoor installations, while the 120V AC power requirement aligns with central alarm circuits in many commercial buildings.
Safeguard Supply Fire Alarm Bell – 12V DC
This 12-volt DC bell is designed for versatility, capable of serving as a fire alarm, doorbell for hearing-impaired users, or a loud signaling bell in industrial settings. The bell is made from industrial-grade ABS material, offering resistance to oxidation and chemicals for demanding interior locations. It supports multiple installation methods by wiring into any device with a 12V DC output, enabling integration with existing control panels or standalone signaling setups. Its simple, robust construction makes it suitable for warehouses, schools, or large indoor facilities where a compact but prominent alarm is needed.
Alarm Bell, 4 Inches Metal Fire Bell for Outdoor(12V)
The 4-inch metal outdoor alarm bell is designed for wall or ceiling mounting and includes a portable wired power supply for easy installation. The surface finish uses electroplating to enhance corrosion resistance, making it a practical choice for exterior use where exposure to moisture or salt air is possible. It features strong tapping and reliable operation, delivering a durable option for smaller outdoor alert needs or secondary signaling in larger systems. Its modest size makes it adaptable for compact installations in outdoor stairs, walkways, or utility areas.
Estink CB-6B 95dB Fire Alarm Bell
The Estink CB-6B offers a robust 95dB alert at 110V AC, with an aluminum base that emphasizes durability in demanding environments such as schools, elevators, factories, and construction sites. The alloy construction withstands wear and deformation, delivering a long service life in outdoor or indoor applications. Its wide application range includes signaling during evacuations or general industrial alarms. The design prioritizes a strong, clear tone suitable for environments where audible alerts must penetrate noise and bustle.
Red Fire Alarm Bell, 10 Inch 120 Volt
The 10-inch fire alarm bell provides a larger audible signal for outdoor areas or open spaces. Powered by 120V AC, it is designed to be used as a school bell or hotel alert, offering prominent sound distribution over a wide area. The larger bell size helps ensure signals cut through ambient outdoor noise, making it a practical option for campuses, stadium perimeters, or large outdoor facilities where visibility and audibility are critical. Back boxes may be required for secure mounting.
Hopoint CB-6B 95dB 5.9in Aluminum Fire Alarm Bell
The CB-6B model from Hopoint delivers 95dB at 110V AC with a sturdy aluminum base, ensuring durability for school, home, factory, or construction site use.

This bell is suitable for indoor and sheltered outdoor applications where reliable audible signaling is essential and where long-term operation is required in challenging environments.
Buying Guide
- Voltage compatibility: Choose a bell that matches your existing fire alarm system or electrical infrastructure (12V DC, 24V, or 110-120V AC, depending on the site).
- Decibel requirements: Higher dB ratings offer clearer alerts in noisy environments; assess the space and audience to determine the minimum effective level (90–95 dB is common for large open areas).
- Outdoor vs. indoor use: For exterior installations, prioritize weatherproof or corrosion-resistant materials and weatherproof back boxes when needed.
- Mounting options: Consider mounting flexibility (wall, ceiling, or cabinet within a back box) and whether additional components are required for secure installation.
- Durability: Aluminum bases and rugged housings improve longevity in harsh environments, such as schools, factories, and construction zones.
- Wiring and compatibility: Ensure compatibility with existing wiring, control panels, and power supplies; many units support multiple installation methods and integration points.
- Certifications and safety: Look for UL or equivalent safety listings to ensure adherence to safety standards for public and commercial spaces.
- Size and audibility balance: Larger bells produce broader sound coverage but may require more mounting space; smaller units fit tighter installations but may need amplification for open areas.
