Honeywell Silent Knight RBB Remote Battery Box 2x33ah

Product Description

The Honeywell Silent Knight RBB is a remote battery box designed to house and support sealed lead-acid batteries for fire alarm control panel systems. It accommodates up to two 33Ah batteries, extending backup power capacity beyond what a standard control panel enclosure can hold. This unit is installed by licensed fire alarm technicians and integrating contractors working on commercial fire detection and notification systems where extended standby power is required by code or project specification.

The RBB is suited for commercial fire alarm installations where the primary control panel enclosure cannot physically accommodate large-capacity batteries. It provides a dedicated, remote housing that keeps backup power organized and accessible. Typical applications include mid- to large-scale commercial buildings, institutions, and facilities requiring extended battery backup runtime to meet NFPA 72 standby power requirements.

Key Features

• Accommodates up to two 33Ah sealed lead-acid batteries for extended backup power
• Designed as a remote enclosure, keeping battery mass separate from the main control panel
• Supports compliance with NFPA 72 standby power duration requirements
• Sold as an individual unit (each)

Compatibility

Designed as an OEM-style remote battery enclosure for use with compatible Honeywell Silent Knight fire alarm control panels requiring external battery expansion.

Installation Notes

Installation should be performed by a licensed fire alarm technician in accordance with NFPA 72 and all applicable local codes. Disconnect and lock out power to the fire alarm control panel before connecting or disconnecting battery leads. Verify battery polarity before making connections, and ensure the enclosure is mounted securely in a conditioned, accessible space free of excessive moisture or temperature extremes.
