DB3BDG048N2BBR EATON

Description

Detailed Parameter Table

Product Introduction

The DB3BDG048N2BBR is a rugged, explosion‑proof audible signaling device designed for harsh industrial and hazardous environments. As part of Eaton’s DB3B series of sounders and alarms, DB3BDG048N2BBR offers a durable, high‑intensity alert signal, typically used in gas zones or explosive atmospheres. The “048” in the model designation indicates its 48 V DC design, and this fits within systems where standard 48 V power rails are used for signaling.

In service, DB3BDG048N2BBR is mounted via its stainless steel ratchet bracket to equipment or structure surfaces and is wired into alarm circuits or safety systems. Upon activation, it emits a loud acoustic output (around 113 dB) serving to alert personnel of faults, hazardous conditions or system states requiring immediate attention. Its explosion-proof housing ensures it can be safely deployed within classified areas, maintaining operational safety and compliance.

Within industrial automation, DB3BDG048N2BBR acts as an essential audible alarm endpoint—integrated with control systems, fire & gas controllers, or safety PLC systems. Where visual alarms may not suffice, this device ensures audible signaling in environments such as offshore platforms, petrochemical plants, refineries, storage facilities, or any zone requiring ATEX/IECEx certified signaling.

Core Advantages and Technical Highlights

High audible output:
DB3BDG048N2BBR delivers a strong 113 dB (approx.) output, ensuring the alarm is heard even in noisy industrial atmospheres, enabling reliable alerting in critical scenarios.

Explosion‑proof / hazardous area suitability:
The device is built to operate safely in gas‑explosion zones, with housing and design conforming to standards typical for the DB3B series. This allows direct integration in Zone 1 / Zone 2 or equivalent hazardous classifications without additional barriers.

Robust construction and mounting:
Its stainless steel ratchet bracket provides secure and adjustable installation capability, resisting corrosion, vibration, and mechanical stress in harsh conditions.

Standard voltage compatibility & ease of integration:
Designed for 48 V DC systems, DB3BDG048N2BBR can be readily used alongside other field devices on standard 48 V rails, simplifying wiring and power infrastructure.

Reliable duty cycling and longevity:
The internal design supports repeated activations without rapid degradation, a necessity for safety systems requiring ongoing readiness and durability.

Diagnostic and maintainability-friendly:
Because it is part of a well-established Eaton DB3B family, DB3BDG048N2BBR benefits from known repair practices, spare-part availability, and integration compatibility across systems.

Typical Application Scenarios

The DB3BDG048N2BBR is ideal for any industrial or hazardous setting requiring dependable audible signaling:

• Offshore platforms and marine structures: to provide alarms for gas leaks, fire, or equipment failure in salt spray and harsh environments

• Petrochemical / chemical plants: as part of gas detection or fire & gas systems, where high audible alert is necessary

• Storage tank farms: to signal alarm conditions or safety breaches across wide, open areas

• Refinery units and process areas: used alongside control and safety systems to alert operators to abnormal states

• Hazardous zone machinery and equipment rooms: mounted near critical machinery as local alerting devices

In all these scenarios, DB3BDG048N2BBR enhances safety through loud, reliable alarm signaling within certified hazardous environments.

Installation, Commissioning and Maintenance Instructions

Installation preparation:
Before installation, ensure the alarm circuit is de‑energized and the mounting location is robust and corrosion-resistant. Verify that wiring cables and glands meet explosion-proof and ingress protection standards. Install the stainless-steel ratchet bracket securely to structure. Provide correct 48 V DC supply capacity and ensure polarity checks.

Commissioning:
Mount DB3BDG048N2BBR on its bracket, route and terminate power supply and control wiring. Energize the circuit and apply a test activation signal. Listen for proper acoustic output and check for distortion. Verify that the device remains stable, that current draw is within specification, and that any supervision or monitoring circuits report normal status.

Maintenance suggestions:
Periodically clean the horn or sound outlet to remove obstruction or buildup. Inspect the bracket, mounting fasteners, and cable glands for corrosion or loosening. Check electrical connections for signs of corrosion or heat discoloration. Test the acoustic output from various distances to ensure integrity. Replace with matching Eaton DB3B spare if output drops below specification. Maintain spares in field stock to reduce downtime.
