Notifier SBB-D4 Backbox Assembly, Four Tiers, Black
The Notifier SBB-D4 Backbox Assembly with four tiers offers an ideal solution for housing multiple fire alarm modules or power supplies in one compact, secure location. Designed for professional installations, this backbox provides ample space, durable construction, and a clean black finish to meet the demands of modern fire protection systems.
Key Features
Four-Tier Capacity
With its stacked four-tier configuration, the SBB-D4 maximizes vertical space without expanding the wall footprint. This layout supports dense module arrangements while maintaining accessibility for wiring and servicing.
Rugged Steel Enclosure
Manufactured from heavy-duty steel, the SBB-D4 ensures reliable physical protection against impact and tampering. Its durable construction also helps safeguard internal electronics from environmental factors like dust and debris.
Black Powder-Coated Finish
The professional black finish not only enhances aesthetics but also adds a layer of corrosion resistance. Consequently, this box performs well in both standard and demanding environments.
Knockouts for Flexible Wiring
The enclosure includes multiple knockouts that simplify conduit entry and cable management. This design speeds up installation and helps maintain a tidy and organized setup.
Applications
Ideal for housing power supplies, chargers (such as the CHG-75 or CHG-120), and other Notifier modules, the SBB-D4 suits installations in commercial buildings, hospitals, schools, and high-rise residential structures. It’s particularly useful in systems that require expanded capacity in a single mounting location.
Installation Recommendations
Install the SBB-D4 on a secure, flat surface using appropriate mounting hardware. Plan conduit entries using the available knockouts to ensure efficient cable routing. Since the backbox accommodates multiple modules, be sure to leave room for airflow and service access.
