The Siemens SL2SBB-R is the red surface-mount back box for the SL2-series of wall notification appliances. Specifically, it pairs with red SL2 horns, strobes, and horn-strobes used in indoor wall installations. In addition, it matches the SL2 trim plate footprint so the appliance sits flush against the wall surface.
What the Siemens SL2SBB-R does
First, the SL2SBB-R provides a clean surface-mount enclosure when no recessed electrical box is available. Then, the SL2 appliance attaches to the back box and the trim plate snaps over the assembly. As a result, technicians can install SL2 appliances on finished walls without cutting drywall or pulling new conduit.

Compatible SL2 appliances
The SL2SBB-R supports the red SL2 wall family. Specifically, it pairs with SL2HWR-N horns, SL2SWR-series strobes (clear, amber, and blue lenses), and SL2HSWR-series horn-strobes (FIRE, ALERT, AGENT, pictogram, and no-lettering faceplates). In addition, it works alongside an alternative single-gang back box or a 4-inch (10.2 cm) square back box when those mounting paths suit the job better.
Mounting and wiring context
The SL2 appliance family uses in-out terminals that accept #12 to #18 AWG wires per Siemens DS 2601. Furthermore, the SL2 series is UL 1638, UL 1971, UL 464, ULC-S525-16, and ULC-S526-16 Listed, plus FM and CSFM Approved. For surface installations, the SL2SBB-R is the appliance-matched mounting accessory called out by the SL2 series datasheet.
