Kidde AB4G-SB Surface Box for Sounder Base

The Kidde Commercial AB4G-SB Surface Box for Sounder Base streamlines surface installations of audible bases, delivering a fast, professional mounting solution for fire and security projects.

Built to Kidde Commercial standards, the AB4G-SB reduces installation time, lowers on-site disruption, and helps ensure consistent placement for surveillance, monitoring, and alarm systems. Ideal for contractors, integrators, and facilities teams, it integrates cleanly into fire mounting and enclosures workflows and helps maintain code-compliant, professional-looking installations.
